WHEEL-FRAME FOR PLWS OR CUL-TIVATORS.

SPECIFICATION forming part of Letters Patent No, 644,875, dated March 6, 1900. Application led October 12, 1899. Serial No. 733,363. (No model.)

Cultivators, of which the following is a specip ication. p

This invention relates to certain new and useful improvements in wheel or sulky plows, the object being to provide a wheel-supported frame, the parts thereof being so constructed as to provide means for attaching to the frame and operating therefrom either abreaking plow-to wit, one with a point, moldboard, and landsideor oultivators,as shovelplows, harrows, or other implements which are attached to beams.

The invention consists in the general construction and combination of the parts, as will be hereinafter set forth and specifically pointed out in the claims.

In the accompanyings drawings,which form a part of this specification, Figure 1 is a side elevation showing a plow applied to a wheel or sulky frame constructed in accord with my invention. Fig. 2 is a rear elevation of the structure shown in Fig. l. Fig. 3 is a plan View of Fig. l. Fig. 4 is a side elevation showing the arrangement or organization of parts of the frame for use as a cultivator or shovel-plow. Fig. 5 is a plan view of the parts when arranged as shown in Fig. 4. Fig. 6 is a detail perspective view of the locking device for one of the levers, and Fig. 7 is a perspective View of a part of the means employed to support the cultivator-,beams The frame is preferably made up of iron or steel and comprises a dat bar A, the ends of which are bent at right angles to form the outer side portions of hangers. To the under side of the bar A is rigidly secured a bar A', which is of less length than the bar A, and the ends depend and form the inner side of the hangers, which construction braces the cross-bar of the frame andprevents its sagging under the weight which is placed thereon. The lower ends of the hangers A2, which are formed by the downwardly-bent end portions of the fiat bars A and A', have journaled therein crankaxles a, and above the bearings are bolts which connect to the hangers segmental plates a' and the ends of bars which constitute a part of the frame. The upper ends of the segmental plates are connected to the frame immediately above the hangers, and said plates have openings to receive the bolts of leverswhich operate both the crank-axles or cultivator-frames, as will be hereinafter set forth.

The forward portion of the frame is made up of a hat bar the ends of which are bent downward and rearward, the lower ends being bolted to the hangers by bolts which pass through the coiled ends of the segmental plates, said plates havinglaterally-projecting side pieces which hold the side pieces of the hanger apart, so as to prevent their being drawn together when the bolt is tightened. To the inclined portion of the bars A3 are pivoted the forward ends of levers B, said levers having spring-actuated bolts or catches attached thereto in the usual manner for engagement with the openings in the segmental plates, the bolts being connected by wires or rods to hand-grips which are pivoted adjacent to the grasping portion of the levers.

lThe bars A, A', and A3 of the frame are connected by bars, as shown more especially in Figs. 3 and 5, and the general construction and arrangement is such as to provide a frame which is extremely rigidpand light and one that can be manufactured without the use of special tools.

lThe horizontal bars of the frame have suitable openings through which pass bolts or equivalent means for connecting to the upper faces of said bars a tongue B', also the support for the drivers seat B2. The depending sides of the hangers A2 have several perforations, which are inline with each other, so that the position of a bail which is pivotally attached to said hangers may be changed, and the inclined portions ofthe bars Ahave openings below the fulcrum of the lever to receive the upper ends of links d4, the lower ends of the links being attached to crankaXles a, which are journaled in the hangers, the outer ends of said crank-axles having mounted thereon the su pportin g-wheels.. The upper end of the link (L4 is constructed so that it may engage with a lever B or with one of IOO the perforations a3 in the bar A3, especially when it is desired to hold the axles in a 'fixed position.

When the frame is used with a breakingplow, the supporting-wheels may be positioned, as shown in Fig. l, so that one of the axles will incline forward and the other rearward to position the supporting-wheel nearest the plow in advance of its point. To raise the frame, power is exerted upon the levers B by bearing down upon the rear ends thereof, which is an advantage, as the weight of the driver or plowman is used to accomplish this end.

To the tongue B, between the horizontal cross-bars A A A3 of the main frame, there are attached depending bars b, which are braced by inclined bars b2, the upper ends of which are adjustably connected tothe tongue, and near their lower ends is a bolt b3, which extends across the plow-beam and connects the bars together and limits the upward movement of the plow-beam, its downward movement being restrained by a bolt h4, which passes through the bars b' underneath the plow-beam and rear of its clevis. The loop which is formed by the bolt b3, the ends of the bars b', and the bolt b4 is of such size that the plow-beam may move freely therein to a limited extent, and the object ofthe series of perforations in the upper ends of the bars is to provide for a range of adjustment, so that plows of different sizes can be attached to the frame.

A lever C is fulcrumed to the tongue B in advance of the frame, and it extends rearward toward the drivers seat, and adj ustably connected to this lever is a link c, through the lower end of which is passed one of the short ends of a bail D. This bail is pivoted to the inner side pieces of the hanger and is connected to the plow-beam by means of a snitable clip. The tongue carries in advance of the f-rame a catch or plate c', with which a detent or ratchet-tooth on the link cis adapted to engage when the lever is raised, and the lower end of said link is moved to one side, so as to be normally held in engagement with the plate by a spring c2, one end of which bears upon the link, while theother end contacts with the bent portion of the bail. To disconnect the tooth or detent from the plate, with which it engages to prevent the bail swinging on its pivot, the end of the lever is moved sidewise and is depressed. Such movement forces the link downward and raises the rear portion of the bail, which is attached to the plow-beam. It will be thus seen that the downward movement of the lever is prevented by the catch, and upward movement is limited by the inturned end of the bail contacting with the tongue. lVhere the bail is fulcrumed or pivoted to the hangers, said bail is flattened and provided with openings, through which pass the connecting-bolts.

Vhen the parts are organized as shown in Fig. 1 of the drawings and the lever is locked,

tions by depressing the lever which is pivoted to the tongue,` and the arrangement of the seat is such that the driver can readily reach the plow with his foot to clean the same or remove obstructions therefrom when the plow is in use, and as the drivers weight is rear of the axles it will tend to balance the frame. Vhen it is desired to hold the plow clear of the ground, the lever C can be depressed and its end caused to engage a hook c4, attached to the rear portion of the tongue.

When it is desired to use the frame hereinbefore described as a frame for cultivators, shovel-plows, or implements of a like nature, the position of the bail is changed, the crossbar thereof being attached to the upper ends of the hangers, and the now forward and depressed ends of the bail are connected to the front ends of cultivator-beams, and braces g g engage with the inturned ends of the bail and extend upward to the bolt which attaches the tongue to the front cross-bar A3. The crank-axles are made fast to the main frame, so that they will preferably incline forward. To the hangers, at points where the bail was previously attached, are pivoted cranks E E, which have arms c c, which engage, respectively, with slots or loops e2 in the levers B, the other arms engaging rollers ff, which have circumferential grooves and are held in close proximity with each other by staples which are 'connected to the upper ends of bars F, which bars have near their central portions quarter-bends, the lower ends being adjustably connected to the beams of the cultivators. By the construction shown the frame, when the plow is detached, may be used as a straddle-row cultivator or for other purposes. The crank-arms and rollers provide means for moving the cultivators sidewise while in use, so that they may be brought near to plants which are not directly in a row, or they may be moved to one side to clear obstructions. By depressing the rear ends of the levers B the cranks will be rocked and the rear ends of the cultivators raised. The cultivators may be of any suitable type, according to the purpose for which they are used, and in some instances the cultivatorbeams are provided with caster-wh eels, which may coact with the wheels to support the main frame.
