PLOW.

SPECIFICATION forming part of Letters Patent No. 708,312, dated September 2, 1902.

,Application filed January 2S, 1902. Serial No. 91.584. (No model.) i

T all whom. t may cm1/06772,:A

Be it known that I, HENRY BRYAN, a citizen of the United States, residing at Modesto, in the county of Stanislaus and State of Oalifornia, have made certain new'and useful Improvements in Flows, of which the following is a speciiication.

My invention is an improvement in the class of wheeled plows, more particularly gang-plows, whose` frame is su pported at the rear end by a wheel adapted for vertical adj ustment for the purpose of varying the depth of furrow or for supportingthe plows proper above the surface of the ground when the plow is being hauled or shipped.

My invention pertains particularly tothe construction, arrangement, and combination of parts whereby the rear wheel is adjusted.

In the accompanying drawings, forming part of this specification, Figure 1 is a perspective view of the main portion of a gangplow frame provided with my improved attachment. Fig. 2 is an enlarged detail view presenting a portion of my improved attachment. Fig. 3 is an enlarged section taken horizontally and practically on the line 3 3 of Fig. l. Fig. 4 is an enlarged section of a portion of the mechanism by which the rear Wheel is locked in any required adjustment. The frame Aof the gang-plow is essentially triangular in form, and its front end is supported by two running Wheels B B and its rear end by a vertically-adjustable wheel C. In practice a series of plows are attached to said frame A and pendent therefrom in gang, and the frontportion of said frame is also provided with a draft" attachment, such as forms the subject of an allowed application for Letters Patent filed by me September 6, 1901, Serial No. 74,480. Such allowed application also exhibits the subject of this present application, but without claiming the same.'

The rear wheel O is journaled upon a stubaXle 1, (see Fig. 2,) which is rigidly attached to a crank-arm 2, having a lateral journal 3, which is hung in bearings 4, attached to the under side of the diagonal bar 5 of frame A. The bearings 4 consist of two perforated lu gs, which are spaced apart to adapt them to receive a collar G, which is applied to the journal 3 of the crank 2, and provided with a of the bar 11.

clamp-screw 7, as shown in Fig. 2, for the purpose of securing it to said journal, and thereby holding the latter in due position in the bearings 4 and atthe same time permittingit to rotate freely,'as required for the different adjustments of the wheel C.

The lower end of the crank-arm 2 is provided with a lateral stud 8 on the inner side, and thereto is attached a rod 9, which extends upward and is pivoted to a hand-lever 10, by which it is adjusted` for changing the position-that is to say, vertical adj ustment--of the wheel O. As shown in Figs. 1 and 3, the head of connecting-rod 9 is inclosed in a keeper 9 and a pivot-pin passes through the said parts. The lever 10 is pivoted at its forward end to avertical bar 1l, which is rigidly attached to the frame-A and provided with a series of holesthat. permit the fulcrumed end of the leverto be adj ustedvvertically as conditions may require. The lever 10 passes througha keeper 12, forming an attachment of a sleevel, which is adapted to slide vertically upon a bar 14, which is also attached rigidly to the frame A a short distance in rear The said bar 14 is provided with a series of holes which are at right an gles to the bar 11. The said sleeve 13 is provided with alined transverse perforations, as shown in Fig. 4, and a locking-pin 15 is adapted to slide therein. The said pin 15 is provided with a reduced extension 15, Whose outer end is connected by a rod 16 With an elbow-lever 17. The reduced portion 15 of the pin is arranged ina tubular extension of the sleeve, consisting of a tube 18 and a cap 19. (See Fig. 4.) A spiral spring 2O encircles therod 15 and presses at its opposite ends against the head of the cap 19 and the pin proper, 15. It is apparent that the spring tends to hold the pin 15 inthe position shown in Figs. 3 and 4 and that since the pin passes through perforations in the'vertical bar 14 the sleeve 13 is normally held locked in any vertical adjustment. The lever 17 :is pivoted to a lateral keeper 2l, attached to the handlever 10, but adapted to slide thereon. The sleeve 13 is likewise connected with the keeper 21 by means of a rod 22. (See Fig.. 3.)

It is apparent that the sleeve 13 slides ou the lever 10 only so far as required by the segment of the slight are through which the leve r IOD moves in adjusting the Wheel C, and itis further apparent that the keeper 21 will be shifted only to a corresponding degree. Thus the lever 17, whose longer arm projects alongside the handle portion 10 ofthe lever 10, is practically always in due position to be grasped as required for the purpose of withdrawing` the pin 15 from locking engagement with the bar 14, which operation enables the sleeve 13 to be shifted up or down by means of the lever 10, according to the height or depth to which the wheelC is to be set. Such adjustment of the Wheel is made for the purpose of varying the depth of the furrows produced by the ploW- shares'or for raising the frame, as may be required to support the shares out of action. By applying the Wheel C to the journal of a swinging crank-arm, as shown and described, and by adjusting such crank-arm at different angles to the vertical bar the wheel C is held steady in any required position, and an improved practical advantage is obtained over plows of this general class in which the rear transporting-wheel is attached to a vertical bar or other vertical member connected directly with an adjusting-lever. As shown in Fig. 1, the side bar of frame A is extended rearward and formed as a handle a, adapted to be grasped by the plowman, and, further, that the rear or handle end of the lever 10 is in such local relation to the handle a that the said lever may be adjusted as required with great facility, the plowman in such case seizing the handle a With one hand and the leverhandle with the other.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with a gang-plow frame having front transporting-wheel, of a rear transporting-wheel, a crank-arm carrying said wheel and journaled on the frame, whereby it is adapted to swing in a vertical plane, a hand-lever fulcrurned on a Xed support in front ofthe wheel, an adjusting-rod pivotally connected with said lever in rear of its fulcrum and also with the free end of the aforesaid crank-arm, a straight bar fixed in vertical position on the frame, in rear of the Wheel, a sleeve adapted to slide on said bar and also on the said lever, and a spring-lock connected with the lever and sleeve, for securing the latter firmly in any adjustment, in the manner shown and described.

2. The combination, with a gang -plow frame, having front transporting-wheel and a rear extension formed as a handle, of the rear transporting-Wheel, a crank-arm upon which the same is journaled, the said arm being journaled in slotted bearings on the under side of the frame extension, a clamp-collar and screw applied to the journal of the arm in the slot of said bearings, a hand-lever fulcrumed at a point in advance of the bearings and extending rearward over the handle of the frame, whereby both are adapted to be conveniently seized and manipulated, a rod connecting the Wheel crank-arm with the lever at a point in rear of its fulcrum, a straight rod iiXed vertically on the frame in rear of the wheel-bearings, and the sleeve adapted to slide on said bar and the lever, and means for locking them together at any point to which the lever may be adjusted, as shown and described.

HENRY BRYAN.
