DEVICE FOR ATTACHING HANDLES TO PLOWS.

SPECIFICATION forming part of Letters Patent No. 362,321, dated May 3, 1887.

Application filed February 28, 1887. i

To all whom it may concern.-

Be it known that 1, CHARLES F. SEAMAN, a citizen of the United States, and a resident of Hamburg, Berks county, Pennsylvania, have invented certain Improvements in Devices for Attaching Handles to Plows, of which the following is a specification.

One object of my invention is to provide for' the ready application of the handles to the plow and their support in proper position on" the plow prior to making the permanent con nections, a further object being to provide for the locking of the attaching device by the straining-bolt usually employed in connection with the two handles.

In the accompanying drawings, Figure 1 is a sectional plan view of part of a plow and its handles with my improved handle-attaching device. Fig. 2 is a side view of the plow with part of the landside broken away and one of the handles shown by dotted lines. .Figs. 3, 4,

side an eye, d, and at therearend of said shank and 5 are perspective views of the handle-attaching plates forming part of my invention, and Fig. 6 a transversesection illustrating the locking. action of the straining-bolt.

In Fig. 1, A represents part of the moldboard,and B part of the landside, of an ordinary plow, D D being the handles of the same. Befo e attaching the handle structure to the plow it is provided with the usual transverse braces, so that the two bars D D will occupy the proper relation to each other.

It is advisable to provide some simple device whereby the handle structure may in the first instance be attached to the plow, and by which it will be retained in its proper position in relation to the plow while it is being permanently fastened thereto. The devices which I employ for this purpose consist of latchplates F and G, the plate F being attached to the inner side of the mold-board of the plow and the plate G being secured to the handlebar D. The plate F has a projecting wing, a,

suitably bent to conform to the curve of the inner side of the mold-board,to which the wing is rigidly bolted or riveted, so that the shank b of the plate projects from the inner side of the mold-board at an angle similar to that of the bar D of the handle structure whenthe latter is in place. The shank I) has on the inner side of the plow by means of the anglebrace I,

Serial No. 229,140. (No'modelJ is a hook, f, and on the plate G of the handlebar is a projecting tongue, 9, for adaptation to the eye (I, and a laterally-projecting wing or finger, h, for engagement with the hook f on the plate F.

' The tongue 9 can be readily slipped into the eye (1 of the plate F, and thelug h then dropped into the hook f, and when this has been done the handle structure will be supported in its proper position in respect to the plow,and the bar D of the plow can be permanently secured to the outer portion of the mo1d-board by means of the curved brace H, and the lower end of the handle-bar D can be secured to the landone wing of which is bolted to said landside and the other wing to the lower end of the handle-bar.

It is usual to provide the handle structure of a plow,near thelower end, witha transverse straining-bar, m, for 'forcing apart the lower ends of the bars D D and maintaining the landside and mold-board of the plow in their proper positions. I utilize this straining-bar to lock the latch-plates G and H in position, each of said plates having a beveled opening, it, which openings, when the two parts are in engagement with each other, coincide and form a beveled recess for the reception of the beveled end of the straining-bar m, the opposite end of which is threaded for the reception of a nut, p, having its bearing upon the handlebar D.

The plates F and H are bolted to the moldboard,and the brace I is bolted to the landside before the faces of said mold-board and landside are ground and polished, so that as the heads of the securing-bolts are ground off flush with the faces of the mold-board and landside, and not afterward disturbed, they afford no obstruction to the free passage of the plow through the soil.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. The combination of the plow and its handle structure with latch-plates, one of which is secured to the mold-board of the plow and the other to one of the bars of the handle structure, one of said plates having front and rear projections and the other plate being constrncted at front and rear to engage with and end of which is adapted to openings in the retain said projections, all substantially as 1 latch-plates, wherebyit serves to prevent the specified. unhooking of the same, all substantially as I 5 2.
