SASHHCORD SUPPORT.

SPECIFICATION forming' part of' Letters Patent N0. l751,858, dated February 9, 1904.

Application filed May 25, 1903. `Serial No. 158,653. (No model.)

To @ZZ whom it may concern.'

Be it known that I, JOSEPH KREIMER, a citi- Zen of the United States, and a resident of Piqua, in the county of Woodson and State of Kansas, have invented a new and Improved Sash-Cord Support, of which the following' is a full, clear, and exact description.

This invention relates to means for supporting sash-cords and counterbalancing-weights for window-sashes, and has for its object to provide a novel simple sash-cord support that is adapted for convenient and quick application, that maybe firmly but detachably secured in the window-easement jamb, and that will afford a reliable support for the sashcord, sash, and weight when applied for service.

The invention consists in the novel construction and combination of parts, as is hereinafter described, and deiined in the appended claims.

Reference is to be had to the accompanying` drawings, forming a part of this specilication, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is a side view of the improvement applied. Fig. 2 is a plan view of the same detached, and Fig. 3 is a front end view of gie device seen in direction of the arrow in In the drawings that illustrate the construction and application of the invention, A represents a sectional side view of a window-casemcnt in part, and B an upper sash held to slide on the jamb of the easement.

rlhe sash-cord support that is to be affixed in the casement-jamb A', comprises the following details: A pair of plate-like'flanges 5, formed integral with and properly spaced apart in parallel planes at the normal inner end of a head-block 6, form with said headblock a pulley-supporting bracket-frame. The head-block 6 is eXteriorly cylindrical and tapers slightly from the outer to the inner end, a thread a being formed in its peripheral surface. It will be seen that two cutting edges 6b extend along the outer surfaces of the flanges 5, these portions of the head 6 serving as reamers to true up a hole into which the bracket-frame is screwed. An openingb is longitudinally formed in the head-block 6,

having parallel sides that are equally spaced apart from the inner surfaces of the anges 5 and are respectively level therewith. In the head-block 6 a grooved pulley 7 is pivoted, as indicated at c, the body of the headblock 6 having opposite recesses 6 formed therein to permit the ends of the pintle c to be secured in place by riveting, said recesses cutting down through the thread va without injury thereto. Between the flanges 5 a grooved pulley 8 is pivoted, the pintle (Z therefor being preferably riveted at its ends upon' the outer sides of the flanges to prevent displacement, and, as shown, the pulley 8 is of greater diameter than the pulley 7. At opposite points on the head-block 6 and flush with the normal outer end of the same two ears 6c may be formed that project outward, these ears each having a screw-hole e therein, as best shown in Fig. 3. It is to be understood, however, that the ears may be dispensed with, if this is preferred.-

In applying the device to the Casement of a window a circular perforation is formed in the jamb wall or stile A at a suitable point for the support of a sash B, the perforation having such diameter as will permit the headblock C to be1 screwed therein, and the cutting-shoulders 6" cut away all inequalities before the thread a enters the aperture.

It will be seen that the ears 6, if employed, afford means to engage a suitable wrench or other lever with the head-block for its enforced rotation within the circular aperture in the Casement jamb or stile A. If the ears 6c are not used, a suitable tool may be inserted in the opening b to turn the head-block 6 and screw it into or out of the casement-jamb.

It is to be observed that, due to the formation of the recesses 6a, abrupt shoulders are formed at opposite sides of said recesses, said shoulders producing cutting edges on the screw-thread formation a, so that the headblock 6 is adapted to cut a continuous screwthread in the defining side wall of the hole into which it is screwed. The ylength of the pulley-supporting bracket-frame, comprising the flanges 5 and head-block 6, is so proportioned that when the latter is screwed into place the ears 6, if used, will contact with IOO the outer face of the stile or jarnb Al and may be thereto secured by screws 7a or similar means.

It is necessary for the proper operation of the device that when it is in secured position upon and in the easement A the pulleys7 and 8 shall be disposed in the same vertical plane at such a point as will permit free play for the sash-cord C in the usual weight-holding box A2, into which the bracket-frame projects. As indicated in Fig. 1, the sash-cord C may be freely engaged with the pulleys 7 and 8, resting upon theV upper portion of their grooved peripheries, so that ends of the sashcord may be respectively secured upon an edge of the sash B and upon a sash-weight (not shown) for a slidable support of the sash.

Having described' my invention, I claim as new and desire to secure by Letters Patentl. In a sash-cord support, the bracket-frame, comprising two parallel-spaced ilanges projected from one end of a hollow head-block, said block being circular on its periphery,

threaded thereon, and having two recesses formed oppositely therein, producing abrupt cutting-shoulders on the thread, which cut a corresponding thread in the wall of the oriice wherein the head-block is screwed.

2. In a device of the character described, the bracket-frame, comprising two parallel-spaced flanges projected from one end of a hollow head, that is circular on its periphery, recessed oppositely therein, provided with cutting edges at the shoulders of the recesses, and having extensions of the cutting edges on the flanges, the circular portion of the periphery of the head having a screw-thread thereon that terminates in cutting edges at the shoulders of the recesses.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
