T0 ALL WHOM IT MAY CONOERN: I

Be it known that I, ALEXANDER ALLEN, of Chicago, in the county of Oooh, and State of Illinois, have invented a new and useful Improvement hiding-Clipping Machine; and I do hereby declare and make known that the following is a full, clear, and exact description of the same, reference being had to thc'ac'companying i drawings, and the letters and figures marked thereon, which form part of this specification.

My said invention consists in a novel machine, whereby the lseams and other hard and knobby portions are cut or clipped from rags in a rapid and eiiicientmanner, and by mea-ns of which the labor ot' preparing rags as 4aforesaid is much more readily and econemically performed than heretofore. i

Toenable those skilled in the' art to understand how to make and use my invention, I will proceed to Q desc'ribe the same with partieularity, making reference in so doing to the I aforesaid drawings, in whichi 'Figure 1 represents a planAor't-op view of` my invention.

Figure n, an end view or elevation ofthe same.

Figure 3 is a. side view or elevation thereof; and

Figure 4 is a vertical section of the same at :v in Iig, 1.

Similar letters of reference denote the same parts of my invention in the di'erent figures.

A represents a table, supported upon any suitable frame, having at or nearits centre an opening, in which are arranged a pair of shears, a b, ot' suitable size, the jaw a beingy stationary, and rigidly secured to the table A, while the jaw Zz opening downwards, is pivoted to the stationary jaw at c, by a suitable rivet, as shown. Upon each side of the shears a Z7, and at their point, there is arranged a movable rest or support for the cloth being operated upon, marked B, which is hinged at one end, as shown at n, in fig. 4, to the table A, at the point of the shears, and is held up above the surface of the table by means oi a spring, S, or its equivalent, sloping `upward from the point to the heel of theshears, as shown., and yielding upon pressure from above, so 'that when the cloth is being drawn up between the shearsduring the operation of the machine, it holds the cloth close up against the stationary upper jaw of the shears, while the movement of the jaw b, as hereinafter specified, cuts the lseam from the cloth, thus greatly facilitating the operation ofthe machine. The said rest or bed-piece B, extending up each side of the shears to the stationary edge a, serves as a guard to preventthe accidental cutting or clipping ofthe Jfingers of the operator. i

The end of Athe handle b of the cutting or movable jaw of the shears is connected, by a ball-and-soclret joint, with a short arm, marked e, said joint being represented at d inthe drawings. The arm e is connected by ajoint,f, to an arm, g, which is rigidly fixed at its opposite end to a .rock-shaft, 7L, which has its bearings in hangers H, attached 'to the frame of the machine, as shown in fig. 3.

` C represents a wheel having a camgroove or way, D, upon its circumference, as shown in tig, 2, supported upon a shaft, F, having its bearings upon the frameof the machine, as shown, said shaft being provided with a. crank, G, and pitman J, `which is connected to a treadle, T, upon a rock-shaft, R, as represented in g. 2, the' machine shown being designed to be driven by the foot of the attendant, revolving` said drive-wheel by means Of .thetreadle T and its connections'aforesaid. -But said drive-wheel may, when desired'or convenient, be opera ated by steam, water, or animal, or any other power. y

By making the joint cl universal, it enables the shears to be arranged at any angle upon the table as desired, or as may, under diii'erent circumstances, be convenient; but where no such variation is desired, the joint d need not be a universal joint. y

By obvious arrangements of the parts of this machine, readily understood by any mechanic, the shears may be so arranged as to act horizontally, instead of vertically, as shown. I

In iig. B, m represents an arm attached rigidly to the roch-shaft 7L, having a point, p, entering the camgrooveD upon the exterior of the wheel C. Thus it will be seen that the revolution of the wheel C, whether accomplished by means of the treadle T, or in any other convenient manner, will give an oscillating movement to the shaft z, and thus impart the required opening and closing movement to the jaw b, while the cloth may be drawn up in the proper positioh, the seam upon one side of the shears, and the cloth upon the other, and thus l the seam will readily and rapidly be clipped 0E and separated as desired.

If' desired, the lower jaw ofthe shears may be stationary and the upper one movable, or both jaws may be movable, t'liough I regard one stationary'jaw and one movable one as the better arrangement.

Having described the construetien and operation of my machine, I will new specify what I claim and desire to secure by Letters Patent.

1. I claim the combination of the table A, shears a b, and movable bed or guard B, all arranged and operating in the manner and for the purposes described and set forth.

2. I claim, in combination with said shears a b, the rock-shaft 7L, arm m, paWl-wheel C, when arranged With connecting arms and joints substantially as specied, and for the purposes described.

ALEXANDER ALLEN.
