|TEXT||THE JACOB PRICE FIELD LOCOMOTIVE
Our Plowing Engine, as it is frequently called, is now in the fifth year of its existence. In that time it has gone into extensive and successful use in nearly all the states and territories lying west of the Mississippi river and a considerable foreign demand, covering nearly all parts of the civilized world, has arisen for it. During the whole of this time the designer of the machine has spent nearly all the summer months in the field, observing its operation at all kinds of work, and this has led to some recent
VITAL IMPROVEMENTS and many minor ones both on the engines and the plowing attachment. The most important of these are described in other pages of this circular. In the matter of strength, durability, quality of work and ease of handling, they place this engine almost beyond criticism. Concerning power, no improvement is claimed because that has always been more than sufficient to do the work that it is represented to do, as all who have seen it work will testify. A CONCISE STATEMENT OF THE CAPABILITIES AND GENERAL FEATURES OF BOTH SIZES OF THESE ENGINES is given on this page and is enlarged upon further on. There are two sizes the smallest being of 40 horse power and the largest of 80 horse power. (Details, relating to dimensions of parts, horse power, capacity, steam pressure, speed of engines, prices, etc., are given in tabular form page 14, but some of the more important facts are also stated here.) The weight of the 40 horse engine is 5 tons three tons less than the 18 horse threshing engines of several makers. Its price, without plows, is $2,500. It travels, when plowing, or doing other heavy hauling, three miles per hour, and can be speeded to about 4 miles when running light. The plowing attachment cuts from 5 to 6 feet according to nature of work at each passage and costs 250. The amount that can be plowed in a day, with the smallest engine will vary from 10 to 20 acres according to condition of soil, energy and skill of operators, promptness of fuel and water supply, length of day, etc., etc. The machine must be run about 21 miles to plow 15 acres, which can be done in 7 hours if it is kept moving. It will haul from 15 to 20 tons of freight, on suitable wagons, over a reasonably good road, having grades not exceeding 300 feet per mile. Has band wheel for running threshing machines or other stationary machinery. The weight of the 80 horse engine is in round numbers 10 tons or from 1 to 3 tons heavier than 18 horse threshing engines of other makers. Its price is 4,000. Its speed when pulling heavily is 3 miles per hour. With a light load 5 miles. The plowing attachment cuts from 10 to 12 feet in width according to character of soil and depth of plowing at each passage, and costs 500. The amount that can be plowed in a day will vary, for causes enumerated above, from 20 to 40 acres. It must run about 21 miles to plow 30 acres. This distance can be accomplished in a day almost without effort. The 80 horse machine will haul from 30 to 40 tons of freight, on suitable wagons, over a fair road having grades not exceeding 300 feet to the mile. [...] The above estimate, as before stated, is for the largest machine. The figures will not be proportionately less for the smallest one. Perhaps from two to three dollars can be saved on fuel. Probably in most localities the cost of a day's run will not exceed 15.00 for the largest and 10.00 for the smallest one. Where prices range as given above and the outfit is intelligently and energetically handled, on lands adapted to steam cultivation, the cost of plowing, per acre, will range from 50 to 75 cents with the 80 horse machine and from 75 cents to 1.00 with the smallest one. The foregoing statement of the capacity and power of these engines is purposely made conservative in order that a demonstration thereof, in the field, may be made easily. The smallest machine is easily of 40 horse power and the largest one of 80, taking the boiler pressure of the former at 175 pounds per square inch and of the latter at 150 pounds. But this must not be understood to mean that they should be worked up to that power constantly but that they can be so worked, temporarily, if necessary. Five years experience with pulling engines has shown that they must have a reserve power and strength of at least one-half in other words that they must be able, in a pinch, to do twice their regular work. The horse power as given above is correct according to the usual method of computation, but to simplify the matter, the pulling power of these machines is given in another form. "The 40 horse engine, besides propelling itself, will do as much plowing or hauling in a stated time, as 20 average horses, and the 80 horse in addition to propelling itself will do as much as 40 horses." This does not mean, however, that the 40 horse engine will pull at the rate of three miles per hour as much as 20 horses will pull at the rate of two miles per hour (which is the walking speed of a horse pulling a full load) or that the 80 horse will pull at three miles as much as 40 horses at two miles. The distance the load is moved must be considered as well as the weight of it. These engines are sold to work as above stated but it is proper to say that either size will move twice the load given as right for it. Thus the small machine will walk along with plows cutting 12 feet (ordinary plowing) and the large one with plows cutting 24 feet; and the small one will move 40 tons and the large one 80 tons on wagons, but the continuous use of this excess of power, which is absolutely necessary to make a plowing or pulling engine a success, would be injudicious and unreasonable. Of course it is plain that if the 40 horse engine should be driven three miles per hour for a long day it would plow over 30 acres and the large one, handled in the same manner, would accomplish 60 acres; but experience has shown that these theoretical amounts are seldom or never accomplished. A high class traction engine is, perhaps, the most perfect machine to which steam has been applied and the work it will do is almost endless in variety. IT INCLUDES PLOWING, FREIGHTING ORE, COAL, GRAIN, ETC., LOGGING, HARROWING, CULTIVATING WITH DISC HARROWS OR OTHER CULTIVATORS, PULLING STUMPS AND RUNNING THRESHING MACHINES, SAW MILLS, PUMPS, AND OTHER STATIONARY MACHINERY. THE REASON FOR THE UNQUALIFIED SUCCESS OF THE JACOB PRICE ENGINES in a field where there had previously been nothing but failures, may be briefly summarized as follows: Great power in proportion to weight. An enormous fire-box or furnace. A boiler of nearly double the strength of any previously used in traction engines, and of great steam generating capacity. The use of very high, superheated steam (from 150 to 200 pounds per inch.) High piston speed, (saving in weight of engine and preventing loss by condensation.). Very high and wide carrying wheels, (of fully twice the bearing surface in proportion to weight of any before used,) keeping the machine on top of the ground. The use of the best, simplest and most direct system of gearing, made in the most perfect manner, each piece of which runs snugly against a strong box (thus securing perfect alignment and avoiding unfair strains on the teeth and preventing friction.) The simplest form of construction possible and the use of steel to the almost entire exclusion of other material, (resulting in a machine that is very light in proportion to its power.) These engines carry very much higher steam than ordinary traction engines and therefore get a much greater amount of work out of a gallon of water or a pound of coal. The enormous advantages of high steam, (as exemplified in the modern steamship and railroad locomotive) have not, until now, been made available for threshing and farm work but it cannot be doubted that its superiority and economy will be as great in this field, as in any other.
A VERY SIGNIFICANT AND IMPORTANT FACT in connection with these engines must not be overlooked. The weight of metal in them, per horse power, is about 250 pounds against about 750 pounds in the common traction. This fact alone is sufficient to account for their success. In making this engine the utmost effort was put forth to make it LIGHT IN PROPORTION TO ITS POWER. Too little power and steam making capacity and too much weight has been the almost fatal defect of pulling engines hitherto. The builder of this machine has gone on the theory that a Field Locomotive must be light and very powerful and have large wheel surfaces so that it will stay on top of the ground and roll over it, not consume half its power in pushing two or three ditches through it in its progress. THE OBEDIENCE AND ACTIVITY OF THESE MACHINES IS SOMETHING REMARKABLE. At a touch of the link lever they will move forward or back, an inch at a time if desired, or according to size of engine will walk off with a train of common loaded wagons from 100 to 200 feet long or with plows cutting from 6 to 12 feet. Or, if required, they will roll across a plowed field, or other ground as difficult, almost as fast as a man can run. They will go slowly down the steepest hills, climb over shrubs and logs in forests or lift themselves up an almost perpendicular bank eighteen inches or more in height. The use of an upright boiler permits these engines to ascend or descend grades of any inclination without uncovering the crown sheet. THE WORKMANSHIP OF THESE LOCOMOTIVES is of a very high character. The engines have piston valves controlled by a very neat and perfect acting form of link motion. The valves have spring packing rings (4 in each one) and never leak. They are, as is well-known to engineers, perfectly balanced and move as easily under 150 pounds pressure as under none. The gearing has teeth of the most perfect form obtainable, much of it being made from cut metal patterns. The water tank of this machine is very large (500 gallons for the larger and 300 for the smaller) and is built into and forms part of the frame. It is located low so that it can be filled, by gravity, from a wagon tank, in one or two minutes. This saves over one hour per day, as it requires from 15 to 20 minutes to do this, when the water has to be transferred with a pump or small hose.
SPECIAL NOTICE. The Jacob Price Field Locomotive for freighting, plowing or other work will be sent to any part of the United States east of the Rocky Mountains, warranted to work as represented in this circular. Payment for it must be deposited with the manufacturer, or with third parties, previous to shipment. This will be promptly returned if its work is not fully up to the representations. A competent man will be sent from the factory to superintend the starting and working of it for a few days and no charge will be made for his services or expenses. All expenses of operating in when on trial, and the freight to destination, must be paid by the intending purchaser, and will not be refunded under any circumstances. Experience has shown that the purchaser is rarely, if ever, ready to handle the machine to good advantage on its arrival. From one to three weeks is required to familiarize the men with their duties, to get the proper equipment of tools, etc., and to obtain a prompt fuel and water supply, hence a large day's work, at first, is not practicable. Therefore, it must not be expected that the person sent from the factory will remain until the machine does a large day's work, but only until it has shown that it will do so when properly handled. When the engine shows that it will pull the plows, or do other work as represented, maintains steam while doing so, stays in order without serious breakage, travels as fast as stated, and in a general way operates as represented in this circular, the duties of the person sent from the factory will have been performed. In case a machine fails to comply with the representations, it must be returned to the most convenient railroad station and loaded on a car at the expense of the party for whom the trial was made. When an engine is sold under a special contract the provisions thereof will, of course, take precedence of those of the above Special Notice.
