Y BALING-PRESS.

SPECIFICATION forming part of Letters Patent No. 3771.942, dated February 14, 1888.

Application filed April 3, 1886. Serial No. 197.652. (No model.)

.To all whom it may concern:

Be it known that 1, OWEN B. KINNARD, of Minneapolis, Hennepin county, Minnesota, have invented certain Improvements in Baling-Presses, of which the following is a speciflcation.

This invention relates'to improvements in presses for baling hay and other brous material; and the object Ihave in view is to provide an improved means for operating the plunger of the press. f

rIhe invention consists,generally,in the construction and combination hereinafter described, and particularly pointed out in the claim.

In the drawings forming a part of this specication, Figure 1 is a side elevation of a portion of thepress, showing a portion ofthe plunger with the means for operating th same. Fig. 2 is a plan of the same.

2 represents the frame-work of the machine, which may be of any suitable construction.

3 represents the plunger, which may be of any preferred construction, and reciprocates in a rectangular plunger-case, 5, intowhich the hay is fed through a suitable hopper, (not shown,) and from which it is forced by the vplunger into the baling-chamber. The balingchamber may be of any ordinary or preferred construction. The plunger is connected by a pitman, 7, with a crank, 9, that is journaled in a bearing, 11, upon a suitable support, 10. A'geanwheel, 13, is mounted upon a stud, 15, and is driven through a gear or pinion, 17, that engages therewith. The pitman is secured to a suitable crank-pin, 19. One end of this pin is secured to the crank9 and the other is secured to asliding block,21,that is mounted in a radial slot, 23, in the gear-wheel'. The gear 13 is turned by the pinion 17. The crank 9 is thereby turned on its axis, and the pitman and plunger are reciprocated. The throw of the crank is suicient to move the 4block 21 back and forth in the slot 23. Power is applied to the circumference of the gear-wheel, and its center forms the fulcrum, the Aradius of the gear being one arm of the lever through which power is applied to the pitman and the portion ofthe radius between the center andthe position of the crank-pin at any point inthe revolution of the gear being, at that point, the other. The axis of the crank 9 is on the side of the center of the gear 13 farthest from the plunger. Y

When the parts are inthe position shownin Fig. 1, and from this point until the plunger begins to recede, the crank-pin is very near the center of the gear. The leverage is therefore very powerful, which gives the plunger great force at the time when it is compressing the hay in the bale. After the crank-pin passes below the centerit begins to move toward the circumference of the wheel, giving to the plunger. a quick return movement. plunger has a quick movement in the first part of its stroke, a slow movement with great power in the latter part thereof, and a quick return movement, as described, which is an especially desirable movement for apress of this class.

I claim as my invention- The combination, in a baling-press,with the wheel having the radial slot 23, the crank 9, the crank-pin 19, to which the pitman is connected, and the block 2l, fitting in the slot 23 and having the crank-pin secured thereto,sub stantially as described.

The

reciprocating plunger and pitman, of the In testimony whereof I have hereuntoset my hand this 29th day of March, 1886.
