ments in Potato-Harvesters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.
This invention relates to potato-harvesters; and it consists of the novel construction, combination, and arrangement of parts hereinafter shown, described, and claimed.

Fig. 3 shows aclutch by means of which the operating-gear is thrown into and out of operative position. Fig. 4 is a sectional view showing a portion of 2c the carrier. Fig. 5 is a perspective view of a platform andsupport carried by the rear end of the machine. Fig. 6 is a longitudinal sec tional view taken through the entire machine and shows the arrangement and construction of the different parts. Fig. 7 is an enlarged detail view showing the means by which the driving-gear is normally held in position. Fig. 8 is a perspective view of a portion of the mechanism carried at the rear of the ma- 0 chine. Fig. 9 is a view of the machine from the rear. Fig.10 is a perspective view of the lower carrier. 7
Referring to the drawings, 1 indicates the traction-wheels, carried by which is asuitable 3 5 frame or bed 2, preferably of corrugated iron.
The said frame is provided with an open bottom, and pivoted to the sides of the said frame and inclining downwardly toward the front is a carrier-frame 3, which is provided on its 0 lower end with a digger-point 4, the purpose of which is to operate beneath the surface and raise the potatoes up to the carrier. Said frame is provided with a vertical side 5, by
means of which the potatoes are retained on thecarrier, which will now be described.
The. carrier-frame 3 is constructed with an open bottom and carries near its upper extremity a horizontal shaft 6, and a similar shaft 7 is carried near the lower end of the said carrier-frame. Inclined strips 9 form r p the bottom of the carrier-frame and are spaced a suitable distance apart to allow the passage of the soil as it becomes separated from the potatoes. If preferred, the bottom 9 may be shaken during the operation of the machine in order to facilitate the separation of the soil from the potatoes. Rigid with the shafts 6 and 7 are sprocket-wheels 10, around which are carried chains 11, to which are secured at suitable intervals the strips 12. The potatoes as they are raised by the point 4 are carried up to the strips 9, and the operation of the chains 11 carries them up by means of the strips 12, and at the upper end of the carrier frame they are deliveredinto asuitable pocket 13, from which they are taken by the upper carrier and delivered to any suitable receptacle.
The carrier-frame 3, as stated, is pivoted to the frame 2, and may be raised or lowered 7e and adjusted to variations of the surfacelevel. The shaft 6 projects a suitable distance through one side of the frame 2 and carries on its outer end a pulley 14, around which is passed a belt 15, which also passes around a similar pulley on the shaft 16, supported in bearings in the sides of the frame 2, and carried on the opposite end of the shaft 16 is a gearwheel 17, which meshes with the internal gear-teeth 18 of the wheel 19. Said wheel 19 is keyed on the shaft 20, supported in bearings in the sides of the frame 2. The shaft 20 projects beyond the wheel 19, and feathered thereon by means of an integral key 21 is a gear-wheel 22, the key 21 operating within a keyway 23. The outer end of the shaft 20 is provided with an integral head 24, and a spring 25 is mounted around the shaft between the head 24 and the wheel 22, thereby holding the wheel 22 in operative position.
Rigid with the rear axle is a large gearwheel 26, with which the spring 25 normally holds the wheel 22 in mesh, and as the machine is drawn over the surface the rotation 5 of the axle and the wheel 26 will rotate the shaft 20, and through the connecting-belt 15 the shafts 6 and 7 will be rotated and the strips 12 will be moved, carrying the potatoes up and delivering them into the pocket 13 in the manner described. On some occasions it is desirable to move the machine with- 5 by to remain stationary. This is done by means ofa'friction-clutch, the construction of which is 'best'shown in Fig. 3.
A rod 27 is supported by the side of the frame 2 and has its rear end bifurcated, as indicated by 28, and the bifurcated rear end engages around the shaft 20, between the wheels 19 and 22. A wedge-shaped member 29 is carried by the fork 28, and when the rod 27 is drawn forwardly the said wedge is drawn between the wheels 22 and 19 and the spring 25 is compressed, the wheel 22 being thrown out of mesh with the wheel 26. The pa nay be retained in this position aslong as desired, and when it is desired to throw thorn again into operative position the rod 27 is moved rearwardly, removing the wedge shaped member 29 from between the'wheels 1:9jand'22, and-the tension of the s'pring 25 wiliautomatieally throw the gear 22 back into mesh with the wheel 26.
Carried by the frame 2, adjacent to the pocket 13, is a shaft 30, and a similar shaft 31 is supported by the rear end of the fraine 2. Sn, po -ted between the shafts 30 and 31 is a As shown in Fig'. 6, the carrier-strips 35 operate within-the pocket 13, and the potatoes as they are delivered into the pocket will be receiyed by the upper carrier and will be carrieid upwardly above the frame 32 and delivered at the rear of the machine.

serving thepo'tatoes. A platform or support chin-e is in operation.
supported by the frame 3B is a fan-casing 45, within which; is carried frame 32; comprising a series of strips l1av The potatoes at the rear of the mao-hinearedelivered ontoa frame 38, are ranged at a suitable incline, from which they t-"QI end of the platform 39 isa vertical n em or 40, hinged to which is a deflecto'rplate 41-, by means of which the potatoes may f be caused to pass on either side of the plat form, as desired. Supporting-loops 42 are snpported by the platform 39, and rigid with the said loops are the suspending-hooks 43', Q by means of which any receptacle may be; supported ad jacent to the platform 39 for reerejiee beyond theend of the casing and carries a small pulley 5 1. Apulley 52 is secured upon the end of the shaft 31', and a belt 53 is'passed around the said pulleys 51 and 52, thereby rotating the fan whenever the machine is in operation. The current of air created by the fan .50 passes out through an opening 54 and assists in removing foreign particles which may have been carried up with the potatoes. 7
The shafts 55 and 56 are supported by the frame 2 above the shafts 30 and 31, and wheels 57 are carried by the said shafts, around which are passed chains 58. Connecting-rods 59 are carried by the said chains 58, and projectingfroni the rods 59 are fingers or projec-' removeit from the potatoes, carrying it upwardly to the shaft 56, where it is removed by means of the hooks 62, with which it ongages as the carrie-Fframe op rates. The books 62 project'rearwhrdly and downwardly, and the material which is engaged thereby will become detachedand drop to the ground. A sprocket-wheel 63 is carried on the end or the shaft 31, and asimilar'sprocketwheel 64: is carried by the shaft 56, and a chain 65, passing around the said sproeket-wheels, supplies the motive power whereby the shaft 56 is driven. The said shaft-56is supported by the rear ends of the gear-racks 65-, slida-bly carried by the frame 2-. A gear-wheel 67, sup ported onthe trunnion 68, meshes with the rack 66, and whenever said gear-wheel 67 is I 3 rotated the rack 66 and the shaft 56 'will be p 0n the outer end of the shaft 31 isa sprocket I 3'6, and a chain 37 passes around the wheels 19 and 36, thereby rotating the shaft 31 and operated. An arm 69 depends from the trunnion 68, and pivoted to the lower end thereof is an operating-rod 70-, which projects forwardly along the side of the machine and terminates adjacent to the'seat 71. The operator by moving the rod 70 will rotate the-pinion 67, thereby operating the racks 6G and moving the shaft 56 inwardly or outwardly, as required; Whenever the shaft 56 is moved, the chains 58 will be placed in a greater or less tension, as the case may be. H
Supported by the frame 2 above the chain 37 is a trnnnion 72, upon the outer end of which is a small 'sprocket whe'el 73, whioh is operated by the chain 37. A second sprocketwheel 74 is carried by the trunnion 72, and a chain 75 passes around'the said trunnion and l u p is carried forwardly around thev spro'clcet- 4-415 carriedbelow the platform 39, upon: "which the operator may stand when the mawheel 76, carried by the shaft 77, supported in bearings above the frame 2. A shaft 78-,
corresponding to the shaft 77, is supported 2 below the frame below'the frame 2 in advance of the carrier frame 5, and sprocket-wheels 79 are keyed a rotary fan 50, the shaft of which projects upon the said shafts. Chains 80 are passed ICC around the sprocket-wheels 79,and the carrierstrips 81 are secured to the said chains 80.
By this means an auxiliary carrier is formed which cooperates with the carrier in the carrier-frame 3 and assists in elevating the potatoes into the pocket 13 and also assists the carrier mounted around the shafts 55 and 66 in engaging with the herbage.
All the parts heretofore described are driven when the gear 22 is in mesh with the gear 26; but whenever the gear 22 is out of mesh with the gear 26 the entire mechanism will remain stationary and the machine may be drawn over the surface without operating an y of the parts.
Connected to the sides 5 of the carrierframe 3 are the rods 82, which extend upwardly within the frame 2 and operate within suitable guides. At the upper edges of the frame 2 the rods 82 are turned forwardly and are again bent downwardly, forming a vertical portion 83, which operates within the guides 84:. (See Fig. 6.) On the lower ends of the vertical portions 83 are carried colters 85, which operate in alinement with the sides 5 of the carrier-frame.
On some occasions it is desirable to move the machine over the surface without having the lower carrier-frame in contact with the earth. As a means for raising the said carrier-frameI provide a lever 86, pivotally carried by the frame 2. To the lower arm of the lever is connected a rod 87, the opposite end of which is secured to the sides 5 of the carrier-frame. A ratchet-segment 88 is secured to the frame 2, and a pawl 89, carried by the upper arm of the lever 86, operates upon the said ratchet-segment, thereby retaining the carrier-frame in any adjustment in which itis placed.
The carriers 35 operate around the grateframe 32, the members of which are arranged at such a distance from each other as to allow the smaller potatoes to drop downwardly and be received within a receptacle 90, supported below the frame 2, while the larger potatoes are carried upwardly and delivered onto the frame 38, from which they are removed in the manner described. The rear end of the receptacle 90 is provided with a hinged bottom 91, which may be operated downwardly, thereby allowing the potatoes which may be received within the said receptacle to be removed therefrom. I provide a means for operating the said bottom comwhich is best shown in Fig. 1.
prising the lever 92, which is connected by suitable connections to the rear end of an operating-rod 93, carried in suitable bearings 94, secured to the side of the frame 2. The forward end of the operating-rod is arranged adjacent to the seat 71, the arrangement of By drawing the rod 93 toward the rear the lever 92 and the connections connecting the same to the rod 93 will be operated, thereby lowering the rear end of the bottom 91 and allowing the potatoes to drop out of the receptacle 90.
I claim- 1. In a potato-harvester, an inclined carrier-frame having a grate-bottom, an adjustable digger carried by said frame, an elevating-carrier operating around the grate-bottom of the carrier-frame, a pocket above the carrier-frame for receiving the potatoes, a vinecarrier operating close to said pocket, an anxiliary carrier above theinclined carrier-frame for assisting the elevating-carrier and for delivering the vines to the vine-carrier, a second potato carrier for receiving the potatoes, means for. asserting and for delivering the smaller potatoes into a receptacle supported below the frame, the larger potatoes being carried by said second-mentioned potato-can rier onto a suitable frame at the rear of the machine, and means for delivering said potatoes from said frame into any suitable re ceptacle, substantially as specified.
