HARVESTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 767,795, dated August 16, 1904. Application filed December 23, 1902. Serial No. 136,410. (No mode To all whom, it may concern.-

Be it known that I, ANDRE OAs'rELIN, a citizen of the French Republic, residing at 17 Rue St. Florentin, Paris, France, have invented certain new and useful Improvements in Mowing and Reaping or Harvesting Machines, of which the following is a specification.

This invention relates to harvesting-machines.

The object of the invention is to provide an efficient machine which may be used either for mowing or reaping or for harvesting.

The present invention is adapted to effect I 5 accumulation and compression of the material by separate mechanisms, and it effects the placing on the ground of a sheaf that is as compact as possible without being bound, the material being ejected at intervals of time regulated with the density of the cropor with the size of the sheaves.

For the purpose of the invention I provide a novel mechanism by which a series of rakes are provided for effecting the accumulation of the material, which rakes are lowered during a portion of the operation and are then raised and held in an elevated position while the material, which has been accumulated by the rakes in their lowered position, is ejected. In the accompanying drawings, Figure 1 is a plan of the whole machine. Fig. 2 is a section on the line A B, Fig. 1. Fig. 2 is a view showing in detail the oscillatingdevice of Fig. 2 in its second position. Fig. 3 is a 3 5 detail top plan view of a portion of the mechanism represented in Fig. 2, the deck or platform of the machine being omitted. Fig. t

is an elevation (as seen from the interior of the machine) of parts comprised in Fig. 3. 4 Fig. 5 is a section on the line C D of Fig. 1 seen from the right-hand side. Fig. 5 is a detail bottom plan view. Fig. 6 is a section on the line E F of Fig. 1. Fig. 7 is a section on the line G H of Fig. 1, and Figs. 8, 9, and

10 show separately details of some of the parts in Figs. 5 and 7. Figs. 11 and12 show in detail a system of adjustment by universal joints for the rod operating the cutter-bar of the machine. Figs. 13 to 16, inclusive, are longitudinal sectional elevations of the platform or table of the machine, showing particularly the action of the rake members and certain of their associated parts.

According to this invention the moving device for transporting the material or crop toward theend of the platform or table 12 consists of two chains 1, moving parallel to each other and operated by two pinions 2 and passing over guide-pinions 3 at the right of the machine. The driving of the machine, which may be operated either mechanically or by animal-traction, comprises a main shaft 4:, carrying an endless screw 5, transmitting motion to achain 6, which operates the releasing mechanism hereinafter described. The shaft 4 is in connection with a countershaft 4, which operates the chains 1 by toothwheels 7 7, and the shaft 4' carries at one of its ends the crank 8, which drives the cutterbar of the machine. The chains 1 are connected to each other by two rods 9, arranged at points dividing the chain into two equal parts. These rods are formed of tubes connected to a link on each chain in such amanner as to turn freely. For this purpose the link carries a sort of trunnion 10, in which the end of the tube engages, as shown in Fig, 3.

The tubes 9 carry a series of rake-teeth 11,

, which project above the platform 12 of the machine, which is grooved or slotted throughout its length in order to give them passage. These grooves are shown by the dotted lines 13 in Fig. 1.

At the end of the platform curved arms 14:, (shown in Fig. 5,) which I term accumulators, are employed, against which the material is presscd as it is pushed forward by the teeth 11 of the rakes. Since the presence of the material thus pressed would prevent the rakes reaching the end of their course, and, on the other hand,- it is necessary for allowing the ejection of the material to allow the teeth of the rakes to go to the end of the platform, an arrangement is provided enabling these teeth to descend to beneath the platform at a certain distance from the end during the accumulation of the material and to project when the ejection is to take place. For this purpose the rakes carry on one side a small eleat 15, Figs. 2 and 3, having a friction-roller 16 at one end which moves along a guide 17, consisting of a U-shaped rod, of iron, fixed to the wooden girder 18 of the machine. At the place where the teeth 11 should be lowered or depressed this grooved rod is joined by a part 19, constituting a switch jointed at 20.

The axis is connected by a link 21, connecting the crank- arms 85 and 86 on the shafts 20 and 22 to an axis, Figs. 4 and 5, which extends from one side of the machine to the other, passing under the table which supports it. When the part 19 is in the position shown in Fig. 2, if the rake be displaced in the direction of the arrow F the friction-roller 16 will be deviated from a straight line while passing along the groove 17 and a partial rotation will be imparted to the tube 9, which carries it, and the teeth 11 will be inclined, so as to come under the platform. To secure the complete lowering of these teeth, I arrange below the plate 12 an arm 23, attached to a spring 24, fixed to the girder, 18 and having a tendency to draw it in the direction of the arrow shown in Fig. 3. On the axis 20 a linger is fixed, which when the links 21 occupy the position shown in Fig. 4 rests on an inclined plane 26 of the spring-pressed arm 23, so as to thrust it inwardly. When the links 21 are lowered, the finger 25 releases the arm 23, which is drawn outwardly by the spring 24, and thus allows the teeth of the rake, which remain projected above the platform, to pass freely.

At the end of the groove in the guide 17 are spring-actuated plates 26, the springs of which serve to normally hold the plates in their effective positions to close the discharge end of the groove. In other words, the plates constitute switches, and when they are engaged by the rollers 16 the latter deflect or thrust the plates or switches downward. As soon as the rollers pass out of contact with the switches they are instantly returned to their initial positions by the power of the springs thereof, thereby to prevent the return of the roller into the groove. At the opposite end of the groove 17 is situated a channeled plate 27, (see Fig. 2,) the channel of which registers with the widened entering end of the groove in the guide 17 and is arranged to receive the rollers 16 during the travel of the rods 9 around the pinion 3, thereby to elevate the fingers to a position above the slotted platform of the machine. Supplemental or auxiliary fingers 28 operate in connection with the pressing-fingers 11 and are adapted as the rollers enter the channel of the plate 27 to travel along the edge of said plate to thereby prevent lateral motion ofthe fingers 11.

In order to secure the passage of the roller 16 from the channel 27 to the groove of the guide 17-that is to say, in order to prevent it from escaping from the space which must necessarily exist between these two parts-a finger 28 is provided on the rod 9, which finger bears under the aforesaid plate and keeps the rake in position. To cause the discharge of the material to take place at intervals of time varying according to the density of the material, oscillation of the part 19 must be produced at variable intervals of time, and this is effected by the mechanism shown in detail in Figs. 5 to 10. On a fixed cross-bar-29 of the machine, Figs. 2 and 7, supported on one side by a support 30 and on the other side by a support 31, slides a tube 32, terminating at one end in a hand-wheel 33 and atthe other end in the integral enlargement 34, provided with a catch or finger 35. Within the enlargement 34 a spring 36 is arranged, said spring bearing at one end on the washer 37, suitably fixed to the shaft 29, (see Fig. 10,) and at its opposite end against the plate or washer 38, closing the open end of said enlargement and rigidly connected therewith. The plate 38 is free of said shaft, from which it will be apparent that when the sleeve 32,

and naturally its integral enlargement, is

drawn toward the right in Figs. 7 and 10 said spring will be compressed in order that on the release of the hand-wheel 33 the spring will return said sleeve to its original position. To facilitate this movement, a fixed wheel 39, serving as a rest, is arranged behind the Wheel 33, the tube 32, with its sleeve 34, turning freely on the cross-bar 29. At the side of the sleeve 34 is placed a cam 40 with afinger 41 and a notch 42 for receiving the catch or finger 35 of the sleeve 34. At the side of this cam is placed a wheel 43, which, for example, is a wheel with thirteen teeth arranged like a wheel of twenty-six teeth with every alternate tooth suppressed. This wheel is opposite a cam 44, placed on the shaft45,-so that it makes a thirteenth portion of a turn for a turn of the shaft 45. In the face of the Wheel 43 are arranged thirteen grooves 46, in which the finger 35 of the sleeve 34 can also engage, and this finger should have a suificient length to enable it to penetrate into these grooves after having passed through the notch 42 of the cam 40. The course of the tube 32 over the cross-bar 29 should be sufiiciently limited to prevent the finger 35 being released from the notch 42. In other words, the length of the finger 35 is such that it will not leave the notch 42 when the tube 32 is slid outward along the cross-bar or shaft 29. The wheel 43 is made with a ratchet 47 also having thirteen teeth. This ratchet, which can turn freely on the cross-bar 29, (as well as the wheel 43 and cam 40,) is connected to the said cross-bar by a spiral spring 48, and the said ratchet carries a finger 49, bearing on the fixed abutment 50, arranged on the support 31. When the ratchet 47 is no more in gear with its pawl 51, under the action of the spring 48 it takes the position shown in Fig. 5. The cam 44 is arranged in relation to the wheel 43 in such a manner as to cause it to advance a little more than one-thirteenth of a turn, so that the ratchet 47 at each displacement which follows this movement shall advance one tooth in relation to the pawl 51, with which it'is in gear. On the axis 87 of the pawl 51 is a lever 52, one end of which carries a frictionroller 53, against which the finger 41 of the cam 40 bears. The pawl 51 carries a finger 54, which bears on the lower face of the lever 52, so that when this lever is lowered under the action of the cam 40 it also lowers the pawl 51 and releases it from the tooth of the ratchet-wheel 47. The pawl 51 is connected by a spring 55 to a fixed part of the machine. The lever 52 is connected by jointed rods 56 57 to the axis 22, Figs. 4 and 5, which operates the crank- arms 85 and 86, connected by the link 21, itself connected to the oscillating part 19. The operations of this portion of the mechanism is as follows: The position of repose of the ratchet 47 is shown in Fig. 5. By means of the hand-wheel 33 theposition of the finger 41 of the cam 40 can be regulated with regard to the friction-roller 53. If, for example, these two parts be separated a distance corresponding to six teeth of the ratchet or six notches of the wheel 43, the finger 41 and the roller 53 will come into contact after the sixth turn of the shaft 45, (or the cam 44.) As the wheel 43 advances, and with it the ratchet 47, the spring 48 is wound up or tensioned. When the tooth 41 lowers the roller 53, it releases the pawl 51 from the ratchet 47, and this latter under the action of the spring 48 resumes its original po-- sition, and since this ratchet is sleeved onto the wheel 43, which is itself secured to the cam 40 and the sleeve 34 by the finger 35, the mechanism will return to its initial position after each release. At the moment of release the rod 56 is raised and communicates, by means of the lever 57, axis or shaft 20. and link 21, an oscillation to the part 19, which assumes the position shown in Fig. 2, which leaves a free passage for the friction-roller 16 toward the end of the guide 17; but as soon as the said roller meets the second portion of the part 19 it brings it to its original position. It is thus the part 19, which raises the crankarms 85 and 86, connected by the link 21, acts on the axis or shaft 22 and rod 56, and brings the lever 52 back into its original position. The pawl 51, as clearly shown in Figs. 5, 5, and 7, is pivoted on the stud 87, on which is also pivotally mounted the lever 52, which car-' ries the roller 53. Said pawl 51 carries on its lower part a finger 54, bearing on the lower face of the lever 52. When the finger 41. of

the cam 40 bears against the roller 53, the lever- 52 is lowered. The pawl 51 is simultaneously lowered through the finger 54 and disengaged from the ratchet-wheel 47 until the finger 41 isfree of theroller 53. The mechanism is then ready to start again. In order to retain the crank- arms 85 and 86, connected by the link 21, in their extreme positions, a small bolt, such as 58, worked by hand, is provided, placed at or about one of its ends. The bolt 58 is hand-operated when it becomes necessary to either raise or lower the levers 85 and 86. When the release of the mechanism takes place, the discharge of the material or crop commences and at the same instant the accumulators or compressors 14 must be raised. They are connected to the release mechanism, which consists as follows: The accumulators consist of branches 14, fixed to a shaft 59, supported by a cross-bar 60 on the frame of the machine. One end of the shaft 59 is connected by a rod 61, Fig. 5, and crank-arms 61 to a ratchet 62, secured to the axis 63. \Vith this ratchet gear two pawls, one, 64, (whose head forms a bolt,) being connected by arod 65 to the lever.52. The other pawl, 66, is kept in gear with the ratchet by means of a spring 67 and is mounted on the axis 68, which traverses the girder 18. This axis carries a finger 69, which is in the path of the rod 9 of the rakes. When the rods meet this finger, (being displaced in the direction of the arrow shown in Fig. 6,) the pawl 66 is released from the ratchet 62. The pawl of the lever 52 being then lowered acts at the same time on the rod 65, which presses on the pawl 64 and causes the ratchet to advance, and the rod 61 moves and raises the accumulators 14, and these are kept raised by the pawl 66, which remains in gear with the ratchet 62. When the rod 9 strikes against the finger 69, the ratchet 62 is set free and the accumulators 14 drop down again. All these release movements are operated by the shaft 45, which receives its motion from the transmission-chain 6, Fig. 2. This shaft by means of bevel-gear 7 O operates the beaters 71, the position of which may be regulated by any knownor suitable means.

This .machine is intended to mow or reap material of various kinds. For cereals with long stalks the alinement must be retained during their transport to the platform. If they are caused to lie down while making them oscillate round the point 74 of the reaper, Fig. 7, the movement of the reaper or cutter deranges the alinement and entangles the crop. In order to remedy this defect, the following arrangement is adopted according to this invention: The'inclined plane 75, which extends from the cutter 74 to the platform or table'12,

is jointed to this latter in such a manner that it can be raised. Feet 76 under this inclined plane enable it, for reaping, to be kept in the raised position shown-by the dotted lines at Fig. 7.. The arms of the beater 71 will cause the stalks to lie on the platform, they turning on the point 77. The lower ends are thus immediately separated from the cutter and their alinement is not interfered with. When mowing, the plane 7 5 is left in its lowered position, and the height of the beater 71 is so regulated that its arms come level with the cutter-bar and keep it free. Fig. 1 shows on each side of the knife points 78 and curved plates 7 9, which make way through the material and facilitate the forward. movement of the machine, which it will be understood takes place in the direction of the arrow F Fig. 1. The cutter 88 is operated by a crankplate 8 and rod 80. A system of universal joints is employed for the connections of this red. This is shown in detail in Figs. 11 and 12 and consists in fixing at the two ends of the rod 80 plates 81, between which the sleeve 82 can oscillate. The sleeves 82 turn freely the one on the pin of the crank-plate 8 and the other on the trunnion 83 at the end of the cutter-blade. A bolt or pin 8a keeps each sleeve in position. A universal joint is thus obtained which perfectly transmits movement while bending itself to all deformations to which the machine is subject.

Having now particularly described and ascertained the nature of my invention and in what manner it may be carried into effect, I declare what I claim is 1. In a machine of the class described, the combination of a deck, a rake for feeding material along said deck, a switch cooperative with the rake and serving when traversed by the rake to shift the latter into an ineffective or non-feeding position, accumulators for momentarily arresting the passage of material from the deck, and mechanism for simultaneously shifting the switch and accumulators, the switch being shifted into position to throw the rake into its feeding position, and the accumulators into a position to release the accumulated material on said deck.

2. In a machine of the class described, the combination of a slotted deck, a pair of feedchains supported for traveling movement under said deck, rake members pivotally carried bysaid feed-chains, the working portions of which are arranged to extend upward through said slots, a switch located in the path of the rake members and adapted normally to shift said rakemembers into an ineffective position, accumulators at the end of the deck, and mechanism for simultaneously operating the switch and the accumulators, the switch being moved into a position to throw the rake members into their working position and to move the accum ulators into position to permit the release of the accumulated material on the deck.

3. In a machine of the class described, the combination of a deck, a rake for feeding material along said deck, a switch for controlling the position of the rake, a lever, connections between the lever and the switch for shifting the latter, a cam for operating the lever, accumulator-arms at the end of the deck,a ratchet connected with the accumulator arms for shifting the same into a position to release the accumulated material on the deck, and a pawl operable by the said lever for actuating said ratchet.

4C. In a machine of the class described, the combination of a deck, a rake for feeding material along said deck, a switch for controlling the position of the rake, a lever operatively connected with the switch for shifting the same, a cam for actuating the lever, a springtube provided with a projection, the cam having a notch to receive said projection, a toothed wheel having grooves to also receive said projection, a cam for operating said toothed wheel, accumulator-arms at the end of the deck, a ratchet operatively connected with the accmnulator-arms for shifting the latter, and a pawl operated by the said lever for turning the said ratchet.
