JERRY DION, OF NORTH BEND, NEBRASKA.

WELDING-BENCH FOR FLOWS.

SPECIFICATION forming part of Letters Patent No. 386,387, dated July 17, 1888 Application filed August], 1887. Serial No. 245,906. (No model.)

To aZZ whom it may concern.-

Be it known that I, JERRY DION, a citizen of the United States, residing at North Bend, in the county of Dodge and State of Nebraska, have invented a Welding-Bench 1113011 which to Veld the Landside and Share of a Plow Together, of which the following is a specification.

My invention relates to a machine for se cnrely holding in place the landside in an upright position and the share lying flat on a bed, so as to. enable a workman to make the weld more perfeetlyand more quickly than is usually done upon an anvil. I attain this by the mechanism shown by the accompanying drawings and by the specification herewith.

Figure 1 is a front view of the machine; Fig. 2, a back View ofa partofit; Fig. 8, an end view of the same part from the right hand; Fig, 4, a top and front edge view of the bed-plate A; Fig. 5, a top and side view of the clamp B, having a lipped tongue, I), projecting down from it, which slides between the two jaws of the bed-plate A, as at a a in Fig. 4; Fig. 6, a side view of foot-lever C; Fig. 7, a short lever held fast to top end of shaft D by set-screw; Fig. 8, a gage against which upper edge of share is placed to bring it in true line with landside while being welded; Fig. 9, the lower end of shaft D, showing an upper washer, 3, as bearer on the eyebolt 4, and a lower washer, 5, kept in place by a nut. This arrangement keeps the rod from rising when pressure by K on the top of the share as it lies on bed-plate A is put on by depressing foot-lever 0.

Similar letters refer to si milar parts th roughout.

A is the bed-plate, curved on its upper face, so as to form the share when hammered down upon it, and of weight to bear welding on.

B is a clamp, which, when forced forward by upper end of lever O, holds the landside against the upright face of A, as shown at 6 in Fig. 3.

G is a foot-lever working on its fulcrum P, as shown in Figs. 1, 2, and 3.

D is an upright shaft turning on eyebolt 4 in Fig. 9 at its lower end and in abushed hole H is a short lever on D.

K is a bent lever on upper end of D, which, when G is depressed, swings round to the right and holds the share firmly to the top face of bed-plate A.

M is a gage-plate slotted and moving endwise on bolt 0, Fig. 4. This holds landside from moving under blows of the hammer while welding.

O is a bolt which holds M.

P is a bolt, the fulcrum of lever O, and, in connection with tie-rods R It, Fig. 2, holds bedplate down to frame Y.

S is a heavy plank on top of frame, holding all the machinery.

Visa bearing and hold-down of shaft D.

\V is a spiral spring fast to O. Vhen the foot is taken off of 0, this draws lever G forward, throwing top end back, relieving from pressure, while X, another spiral spring, eoneealed in the body of bed-plate A, Fig. 4, forces the clampB back and releases the work.

a a representjaws of A, between which lever 0 moves, clamp B slides, and spring X opcrates.

The machine operates in this manner: The landside on edge is placed between A and B at 6, Fig. 3. The share is laid on top of bedplate A, its top edge against G, the two surfaces to be welded being brought together. Pressure of the workmans foot on lever O forces its top end against B. Then B slides up against landside. At the same moment shaft D turns to the right. Gent lever K swings round, its lower end pressing the share down to bed-plate A. The weld is now made, the foot taken off of O, and the work is released.

What I claim as my invention, and desire to seeu re by Letters Patent, is-

l. The combination of the bed-plate A, having jaws a a and curved on its upper faee,with

ver 0, substantially as and for the purposes described.

3. The combination of the curved bed-plate A, the gage G at one end of it, the clamp B, the lever G, and spring 'W, connecting therewith, the rod D, having lever K at its upper end and the short lever H at its lower, the rod E, and the springX, acting on the clamp, substantially as described.

4. In a welding-bench, a plate fixed to the bed-block and adapted to hold the share, a clamp for holding the landside against said plate, and a spring adapted to operate on said plate, a lever for moving said clamp, and a spring for drawing said lever back, substan- 15 'tially as described.

5. The bed-plate A, having jaws a and spring X therein, and the gage M, combined 7 with the clamp B, having a lipped tongue, 6,

a lever operating said clamp, and a swinging 20 Witnesses:
