WILLIAM BUEL HOERR, OF CHICAGO, ILLINOIS.

SHIPPING-MACHINE.

Specification of Lettere atentr Patented June 16, 1908.

,y Application filed June 17, 1907. Serial No. 379,322.

To all whom it may concern:

Be it known that I, finden B. Honnn, a citizen of the United States, residinga Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in. Clipping-Machines, of which the following is a specification.

My invention relates to improvements in clipping machines, such as are employed in shearing sheep, clipping horses and the like, and has for its salient purpose to provide new and improved construction involving improved pressure devices for maintain-ing effective cutting contact between the oscillating cutter and the fixed cutter.

A In the embodiment oi' my invention shown; Figure 1 is a plan view, and, Fig. 2 a central vertical section, through a clipping machine.

Throughout the drawing like numerals of reference refer always to like parts.

In the drawing 5 indicates a lined cutter or comb, and an oscillating cutter, connected for oscillation by the customary dowels 8 The oscillating cutter lever is preferably of peculiar construction, involving an inclined section 9. which I may term a pressure section, extending downwardly and rearwardly with respect to the plane of oscillation of the movable blade, having adjacent its top a suitable ball seat or recess, and `vthence entending downward, as, shown at 10, at a smaller angle to a ball bearing seat 11 embodied in the lower surface of the lever, and thencecontinuing rearwardly in the form of 'an operating arm 12, connected in any suitable manner with the power appliances, as through the agency of the customary eccentric connections, generally indicated at 13. The frame 14, carrying the comb or rigid blade 5, is provided with a suitable seat for theball 16, with which the bearing 11 coacts, and is provided with the customary housing 17, having a tubular extension 18 alining With the pressure part 9 ol the lever. Threaded in said tubular extension is an adjusting cap 19, of hollow construction, having therein a strong spring 20, at its upper end bearing against an adjusting screw 21, closing the outer end of the hollow cap 19, and at its lower end bearing against the head 23 0f the stud 22,- which takes through a bottom aperture hollow cap. At its end the 'f' 'stud 22 provides a seat for a ball 24, bearing in depression in the cup or head ol link 25,

which at its lower end provides a similar cup bearing uponv the ball 26, resting in the seat ci the extremity of pressure member 9.

New it will be seen that pressure of the spring 20 is applied through the stud 22, the link 25 and the ball bearings at opposite ends thereof, to the pressure member of the pressure portion 9 of the oscillating lever arm, in a direct line, at a considerable'angle, (preferably approximately degrees) to the cutting surface of the movable blade, at a point relatively closer to the movable blade 6 than to thelever fulcrum point 16. By this means the desired pressure for effective cutting may readily be applied to the oscillating blade, and yet the oscillating lever is left com aratively free in its movements upon bal 16. The slight difference in the eiiective distance from the cutting surfaces to the adjusting cap 19, caused by the oscillating movements of the cutter lever, are compensated for by slight axial movements of the head or stud 22, and the 'pressure is maintained practically constant through the agency of the strong coiled spring 20. Obviously the pressure may be accurately'adjustedv by movements of the cap 19.

While I have herein described in some detail a specific embodiment of my invention it will be apparent that some changes may be made therein without departure from its 'spirit and scope.

Having thus, described my invention, what I claim and desire to secure by Letters Patent, oi' the United States is:

1. t In a clipping machine, the combination with a case, a stationary cutter, and a movable cutter, of an oscillating cutter lever arm, comprising a pressure part at an angle to the cutting plane, and means for applying elastic pressure directly to said pressure part in substantial alinement therewith.

2, In a clipping machine, a stationary and movable cutter, a pivoted lever arm bearing upon the movable cutter, having an upwardly extending pressure part between the pivot and the blade, and resilient pressure devices for applying elastic tension directly to said pressure part of the lever in substantial alinement therewith.

3. In a clipping machine, a stationary blade, a movable blade, a pivoted lever arm,

connected with and bearing on said, movable blade, and comprising an upwardly extendmg pressure part, intermediate the pivot and the blade, an adjustable pressure regulating cap substantially alining with said pressure portion of the lever arm, and a connection between said cap and lever arm comprising a link and ball joint at opposite ends of said link.

4. In a clipping machine, a stationary I blade, a movable blade, an oscillating lever arm pivoted in rea-r of said blade and bearing directly upon the movable blade, said arm comprising an upwardly and rearwardly extending part 9, a suitable veasing, an adjusting 4head 19 in said easing, a spring within said head, an axiall movable part carried by said head, a link interposed between said axially movable part and the portion 9 of l5 the oscillating lever, said part 9, the link and the cap 19 beingarranged in substantial alinement.

In testimony whereof I hereunto set my lland'in the resenee of two witnesses.

. ILLIAM BUEL IIOERR. In the presence of JU-L1Us MILLER, W. S. WRIGHT.
