CORN-HARVESTER.

SPECIFICATION forming part f Letters Patent N0. 563,522, dated July 7', 1896.

Application led January 8,1895. Serial No. 534,239. (No model.)

T0 a/ZZ whom t may con/cern.-

Be it known that I, CHARLES S. I/VATERS, a citizen of the United States, residing at lVorstville, in the county of Paulding and State of Ohio, have invented a new and useful Corn-Harvester, of which the following is a specification.

My invention relates to corn-harvesters, and particularly to shocking apparatus for maio chines of that class, and the objects in view are to provide a simple and eicient shockingtable and means for operating the same, whereby as the fodder is cut and is fed rearwardly by the conveying apparatus it is received upon a table, and while being held in a vertical position suitable for forming a shock is carried rearwardly until a suflicient number of stalks have been accumulated, after which the table is dropped and drawn quickly zo from beneath the shock to allow the latter to fall upon the ground, where it remains standing, the table meanwhile being returned to take its position at the front of the machine to replace a second table which is being lled during the emptying and returning of the first-mentioned table.

Further objects and advantages of theinvention will appear from the following description, and the novel features thereof will be particularly pointed out in the appended claims'.

In the drawings, Figure l is a plan view of a machine constructed in accordance with my invention. Fig. 2 is a side view of the saine. Fig. 3 is a longitudinal section. Fig. 4 is a bottom plan view. Fig. '5 is a transverse section on the line 5 5 of Fig. 3. Fig. 6 is a detail section of the shocking apparatus, showing one of the tables as seen just prior to being raised by the elevating-spring at the limit of its return movement. Fig. 7 is a detail section on the line 7 7 of Fig. l.

Similar numerals of reference indicate corresponding parts in all the gures l of the drawings.

l designates the side beams, connected near their front ends by a transverse beam 2 and near their rear ends by a transverse beam 3, said side beams comprising inner and outer beams lad and lb, respectively, connected by interposed spacing-blocks 4 and covered by a flooring 5. Intermediate transverse braces '6 connect the inner members of the side beams.

Mounted in bearings 7 upon the under side of the outer members of the side beams is a driving-shaft 8, to which are attached the ground-wheels 9, said driving-shaft carrying a series of bevel-gears for communicating motion to the various parts of the mechanism comprising the machine.

Stalk-guides or gathering-arms 10 project in front of the framework, and contiguous to their rear ends are arranged the front ends of vertical gathering-aprons 11,mounted upon pivotal frames l2, which are pivoted at or near the rear ends of said gathering-arms and are free at their rear ends to be adj usted laterally. The front rollers 13 of these aprons are provided with bevel-gears 14, with which mesh similar bevel-gears l5 on the short countershaft 16, arranged in the framework and provided with other bevel-gears, 17, which mesh with the gears 18 on the driving-shaft 8, and the rear rollers 19 of said aprons are mounted at their lower ends in sliding blocks 20, the longitudinal slots 2l of which receive stationary guide-pins 22 on the framework, springs 23 being arranged in said slots to press the rear ends of the apron-frames inward or t0- ward each other in pairs, whereby a yielding pressure is exerted upon opposite sides of the stalks as they are fed toward the cuttingknives 24. These cutting-knives are arranged in pairs, with their peripheries or cutting edges overlapping, and they are driven by the shaft 8 through pinions 25, which mesh with the gears 26 on said shaft.

Arranged in rear of the rear ends of the gathering-aprons are the conveying-aprons 27, mounted in frames 28 and 29, the'latter or inner framesbeing yielding to accommodate the quantity of stalks which pass therebetween. The frames 29 are pivoted at their rear ends upon the rear rollers 30 and are provided at their front ends with the rollers 3l, which are mounted in sliding blocks 32, constructed as described in connection with the blocks 20 and provided with actuating-springs The frames 28 are ,pivoted at their front ends on the rollers 3l and having their rear rollers 30 mounted in sliding blocks 32, similar to those IOO above described. Motion is communicated to the conveying-belts from the gears 18 and 26 through the pinions 34 and 34 and the pinions 34b,rwhich are carried by the front rollers of the conveying-aprons.

The space between the inner members of the side beams l is open at the rear to allow the shocks, after being dropped, to maintain a vertical position, and on the inner sides of said inner members of the side beams are arranged upper and lower guides 35 and 36, adapted to receive the lian ged rollers 37 of the shockin g-tables 38, which operate between the side beams, said guides consisting of channels formed by upper and lower webs 39 and 40 and an intermediate web 4l. These guides are connected in front of their center by vertical channels 42 and 43, the latter of which is arranged at the extreme front ends of the guides and the former at a distance in rear thereof corresponding with the interval between the rollers 37, wherebj7 a table may be raised from the lower to the upper guide at the front end of the latter by passing its rollers through the Said upper j of their center by inclined ways 44 and 45, of

which the former is arranged adjacent to the extreme rear ends of the guides, while the latter is disposed at an interval therefrom corresponding with the distance between the rollers 37 of a table, whereby when a table passes along the upper guide to the rear end thereof it may be moved downward and forward through the ways to the lower guide.

The channel 42 and the ways 44 and 45 are provided with bridgingpieces 46, which are normally held in the elevated position (shown in full lines in Fig. 6) by means of actuatingsprings 47, but which may be lowered to the horizontal position (shown in dotted lines in Fig. 6) to complete the intermediate webs or bridge the openings formed therein to allow the flanged rollers 37 to pass freely thereover. Furthermore, an inclined switch 48 is arranged adjacent to the guideway45 and normally bears at its free lower end upon the upper surface of the lower web 40, as shown in full lines in Fig. 6, but which may be elevated to open the lower guide, as shown in dotted lines in said figure. Said switch is norm ally held in its lowered position by gravity. A cushion-spring 49 is arranged at the rear end of each upper guide, and an im pulsespring 50 is arranged at the front end of the same, while between the channels 42 and 43 and secured to the upper surfaces of the webs 40 are the elevating-springs 5l, which curve upward toward their front ends to hold the antifriction-rollers 52 at their upper extremities in the upper guides. Obviously, the elcvating-springs 51 are arranged inward suiiiciently to pass the inner edges of the intermediate webs 4l.

Arranged with their upper sides projecting slightly above the plane of the bottoms of the lower guides 36 are the feeding-gears 53, the

rear gear 53 being arranged adjacent to the lower free ends of the switch 48, and arranged with their upper sides projecting slightly above the plane of the lower sides of the upper guides 35 are the feeding-pinions 54, a similar pinion 55 being arranged with its lower sides projecting slightly below the plane of the upper sides of the upper guides in rear of the way 45. The gears 53 are driven by the main shaft- 8 through the longitudinally-disposed shaft 56, which receives motion through the intermeshing gears 57 and 58 and the transverse shafts 59, which carry said gears and are provided with bevel-pinions 60, meshing with similar pinions 6l on the longitudinal shaft, and the upper pinions 54 receive motion from the longitudinally-disposed shaft 56, through a small shaft 62, driven by intermeshing gears and 64 and provided with bevel-pinions 65,meshin g with similar pinions 66 on the transverse shafts 67, said transverse shafts carrying the feeding-pinions 54. The feeding-pinion 55 is adapted to be operated by hand, and for this purpose its shaft is connected by intermeshing gears 68 and 69 with the spindle of a crank 70, which is disposed above the plane of the upper surface of the side beam. The spacing-blocks by which the members of the side beams are connected form suitable supports for the bearings in which the parallel shafts 56 and 62 are mounted.

Arranged upon opposite sides of the space between the side beams, in position to form supports for a sh ook, are the parallel stationary guide-rods 7l, and pivotally mounted at opposite sides of said space adjacent to the rear ends of the conveying-aprons are the shock-holding arms 72, which approximately meet at their rear free ends above the plane of the shocking-tables and which are held in such position by means of springs 7 3. Spurred packers 74 are located at the rear ends of the conveying-aprons and consist of spurred plates carried by crank-shafts 75, which receive motion from the rollers of the conveying aprons through suitable chaingearing, (indicated at 76.)

The tables are provided at their side edges and upon their under surfaces with racks 77 for engagement by the teeth of the feedinggears 53 and pinions 54, and are provided at one edge on their upper sides with racks 7 8 for engagement by the pinion 55.

This being the construction of the improved apparatus, the operation thereof is as follows: As the fodder is out and carried rearwardly by means provided for this purpose and is fed upon the table which is arranged in position to receive it, said table is moved slowly to the rear by means of the pinions 54, the bridging-pieces 46 being depressed bythe rollers of the table to provide a continuous track. When the table has become filled sufficiently to form a shock and has passed beyond reach of the rear feeding-pinion 54, it remains at rest to give the assistant ICO IIO

opportunity to tie the shock, after which he turns the crank 70 to move the table to the rear sufficiently to carry its rollers over the rearmost bridging-pieces. This compresses the cushion-spring 49, whereby, when the rollers have passed beyond the extremities of the bridging-pieces, which cover the inclined connecting- ways 44 and 45, and said bridging-pieces are elevated at their rear ends to open the said ears, the cushion-spring eX- pands and gives the table an impulse which causes it to pass quickly downward and forward. This rapid downward movement of the table, succeeded by a rapid forward movement due to the engagement of the large gears53 with the racks on the table, draws t-he latter from beneath the shock and allows it to fall vertically to the ground. The table is carried .forward by said large gears until its rollers 37 come opposite the channels 42 and 43, (previous to which it has depressed the free front ends of the elevating-springs 5l.) It is elevated by the springs provided for that purpose to the upper guide 35. The operation of elevating the table strains the spring 50, and therefore, after the rollers 37 have reached the upper guides, said spring 50 gives a rearward impulse to the table and throws it a suiiicient distance to cause the engagement of its racks with the small feeding-pinions 54, which move it rearward to receive another shock.

In order to avoid loss of time between the formation of one shock and the arrangement of the table for a second shock, I preferably employ a plurality of tables operating simultaneously. In the drawings I have shown two tables, one of which arrives at the front end of the upper guide in time to take its place as the preceding table passes from engagement with the rearmost feeding-pinions 54, this being possible by reason of the more rapid return or forward movement than advance or rearward movement. In other words, the loss of time necessitated by tying the shock is compensated for by the succeeding rapid movement of the table when it reaches the lower guide, whereby the table which has just discharged its shock returns to the initial position and is ready to receive a second shock, by the time the shock on the preceding table is completed. Thus the operation of harvesting and shocking is continuous and automatic with the exception of the tying of the shock which occupies a short 'time and which does not interfere with or retard the operation of harvesting and shocking, inasmuch as during the interval occupied by tying the shock a succeeding shock is being formed upon a table which has taken the place of the filled table.

It will be understood that in practice various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the spirit or sacriiicing any of the advantagesof this invention.

Having described my invention, I claimp l. The combination with guiding, cutting and conveying mechanism, and means for operating the same, of a shock-receiving table mounted in guideways, and means for moving the table alternately in opposite directions in the guideways, the movement in one direction being rapid to withdraw the table from beneath a completed shock and the movement in the opposite direction being slow to allow time for the accumulation of stalks to form a shock, substantially as specified.
