DAVID w. SEELY, or ELMIRA, NEW YORK.

CHALK-SUSPENDER.

SPECIFICATION forming part of Letters Patent No. 365,867, dated July 5, 1887.

Application filed November 23, 1886. Serial No. 219,679. (No model.)

To all whom it may concern.-

Be it known that I, DAVID W. SEELY, a citizen of the United States, residing at Elmira, in the county of Ohemung and State of New York, have invented a new and useful Improvement in Ohalk'Suspenders, of which the following is a specification.

My invention relates to an improvement in chalk-suspenders for billiard tables; and it consists in the peculiar construction and combination of devices, that will be more fully set forth hereinafter, and particularly pointed out in the claims. In the drawings, Figure 1 is a side elevation of my invention complete, showing the weightring dropped when not in use. Fig. 2 is a sectionalview ofthe same,showingtlieweight-ring pulled up to the pulley-frame when in use. Fig. 3 is a vertical transverse section of the chalk-holder on the line 2 2, Fig. 4. Fig. 4 is a horizontal section on the line g 3 of Fig. 5. Fig. 5 is a vertical transverse section on the line x 00 of Fig. 4. Fig. 6 is a plan view of the blank from which the chalkho1der is stamped.

A represents a rectangular frame or box, which is made from a single piece of sheet metal bent in the form of the letter U in crosssection and provided on its upper side, at the center, with an opening, 13, through which the screw or pin 0 passes to enter the ceiling and secure the frame A thereto. On the screw or pin 0 is mounted a block, D, that is i nterposed between the pulley-frame A and the ceiling, and prevents the said frame from coming in contact therewith when the pulleyframe is rotated. It will be observed that the frame A is free to rotate on the screw, which thus forms a swivel for the frame. In the ends of the frame A, between the sides thereof, are

' journaled pulleys E, having grooved peripheries,which pulleys are thus arranged at some distance apart.

F represents a counterbalancing weight, which is preferably made in the shape of a ring, providedonitslowcrsidewithopeningsfiwhich are arranged closely together, and on its opposite or upper side with openings f, which are arranged a considerable distance apart. The distance between the top series, f, of openings in the weight-ring is less than the distance between the pulleys E of the pulley-frame A.

G represents a suspending cord, which is passed through one of the lower openings, f, and upwardly through one of the top openings, f, and has one end knotted to prevent it from being drawn through the openingf, thus securing the said cord to the weight. The cord then passes from opening f upward to the pulley-frame A and down throught the remaining openings f andf in the weight-ring. To the lower end of the cord is attached a chalk-holder, H. This chalk-holderisformed from a single oblong piece of sheet metal, as

walls, h, has its outer edges bent under, parallel with the said central portion, h' thereby forming re-enforce strips h, which strengthen the chalk-holder. Through the end walls, h, are made aligned openings h, at a slight distance below the under side of the top h. A

screw, k passes through the openings and has at one end a nut, h. In practice the nut is soldered to the chalk-holder, so as to be held from movement, the screw only being capable of adjustment. The piece of chalk, which is represented at K, is inserted between the end walls, h, and the latter are clamped together onthe chalk by turning the screw it, thereby firmly holding the chalk to the chalk-holder, as will be readily understood. The side flanges, h,on the end walls, h, hold the chalk from lat eral movement.

The operation of my invention is as follows: The device is suspended from the ceil'i ng above the billiard-table. In order to lower the chalk when it is desired for use, it is only necessary to grasp the pendent end of the cord and draw on the same, and thereby draw the cord through the pulley frame A and raise the weight, so as to permit the chalk to be lowered to any desired point. In order to raise the chalk, the ring is grasped and lowered on the cord, as will be readily understood. By providing the ring with the openingsf, arranged at a considerable distance from each other, theportions of the cord betweentho said ring and the frame A will be separated and kept apart, thereby preventing the cord from becoming twisted or entangled by the twisting or rotary motion of the weight. The ring=shaped weight when in use circles around and untwists the cord. It is necessary that the cord be kept untwisted, for when twisted it cannot be drawn through the weight without considerable effort. In' Fig. 2 I show how far the weight can be drawn up in practice. The arrangement of the openings f of the ring at a less distance apart than the pulleys of the frame A is an important factor in preventing the Weight from being drawn up so as to collide with the frame A and injure the I pulleys.

The chalk-holder herein described is capable of adjustment to hold any size piece of chalk, and is substantial and will not get out of order.

Having thus described my invention, I claim 1. The chalk -holder made from a single piece 'of sheet metal and bent to form the top and depending end walls, h, the said end walls having the side plates or flanges bent at right angles to their outer edges, and the top having the bent reenforced plates on its under side, for the purpose set forth, substantially as described.

2. The chalk-holder herein described, made from a single piece of metal bent to form the top and depending end walls, and the screw cord passing over the pulleys, the weight having openings f f, arranged at a less distance apart than the pulleys E, the cord having its pendent ends passing through the openingsf f, one of the ends being secured to the ring and the other end being free and provided with the chalk, as set forth.

4. The frame A, having pulleys E, arranged at a distance apart, in combination with the cord passing over the pulleys, and the weighted ring G, having the cord connected thereto at points less distant than the space between the pulleys E, as set forth.

5. In a chalk-suspender, the pulleys, in combination with the cord, and the weighted ring on the cord, the cord being passed through the center of the ring, leaving side portions of the ring on each side of the cord, as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
