PULIrEY-CASE.

Specification of Letters Patent.

Application filed September 30, 1914. 7 Serial No. 864,229.

To all whom it may concern:

.of the borough and county of the Bronx,

city and State of New York, have invented a certain new and useful Improvement in Pulley-Cases, of which the following is a specification.

My invention relates to pulley cases and has for its object to provide a case which consists of a single piece ofmaterial bent to the desired shape to-form a rigid, durable support adapted to accommodate single, doubleor other pulleys and which is particularly adapted for use in connection with windows of the type commonly known as double hung windows.

Other Objects of my improvement will appear from the description hereinafter and the features of novelty will be pointed out in the appended claims.

Reference is to be had to the accompany ing drawings which illustrate an example of my improvement and in Which Figure 1 represents the blank from which the case is constructed; Fig. 2 is a side elevation of the finished case with the pulley in position therein; Fig. 3 is a plan view thereof and Fig. 4 is an end elevation.

As shown in Fig. 1 the blank comprises two main sections 5 and 6 which converge toward and are connected with a relatively narrow intermediate section 7. The main sections 5 and 6 are continuedtransversely in opposite directions to form auxiliary sections 8 and 9 each of which in turn is prolonged lengthwise to form projecting sections 10 and 10 The main sections 5 and 6 at the edges opposite to those at which the and 10 are similarly provided With openv ings 16 for the accommodation of screws or other fastening devices.

In forming the case the main sections 5 and 6 are bent at right angles to the inter medlate sectlon 7 along the lines 17 to form the opposite side Walls of the case, the section 7 forming the top thereof as shown in Figs. 3 and 4. The auxiliary sections 8 and 9 in the example shownare now bent in opposite directions along the lines 18' until they extend at rightangles to the main sections 5 and 6 in whichcondition the free edge of each section 8 and 9 will lie against an edge of the opposite sections 5 and 6 and theprojectionsll and 12'wil1 be located re-.

spectively in the recesses13 and 14. The said sections 8 and 9 thus form the end walls of the case it being understood that the projections 11 and 12 may if desired be of suflicient length to permit the ends thereof to be bent over upon the sections 8 and 9 for the'purpose of securingthe side walls 5 and 6 and end. walls 8 and 9 firmly together.

At this stage the projecting sections 10 and 10 arebent along the lines 19 soas to extend outwardly from the end walls 8 and 9 at any desired angle thereto to form attaching lugs, the illustrated form showing said lugs extendinghorizontally at right angles to said end walls. In this condition the apertures 15 are in axial alinement so that the pulley 20 may be placed in position in the case and the axle 21 thereof inserted through said apertures and the axial opening of the pulley and the ends of said axle riveted or otherwise secured in the side walls 5 and 6. In this manner the pulley 20 is rotatably supported in the case while the axle 21 provides an additional securing means for maintaining the case in its oper- Patented Mar. 23, 1915."

ative condition against any strains to which the pulley 20 or the case may be subjected.

It will be seen that the completed case is open at opposite corners and at the bottom so that it may be readily utilized to support the pulley in position to accommodate cords or the like extending vertically, horizontally or at any angle intermediate thereto, the lugs 8 and 9 serving as a means for securely attaching said case to a supporting means in each instance. The openings at the corners of the case also permit access to the cords or the like and make it unnecessary to detach the case if such access is desired for any purpose. At the same time the dead Weight of the case is reduced to a minimum Without in any way impairing its strength. By properly proportioning the section 7 and the sections 8 and 9 the case may be made of any desired width adapted to properly accommodate pulleys having single, double or more grooves, or one, two or more separate pulleys if desired.

My improved case is extremely simple in construction, comprises no complicated lines necessitating intricate apparatus to produce and is of maximum serviceability and easy to attach and detach as may be found necessary.

My improved case in all of its forms occupies a minimum of space and is thus particularly adapted for use in places of small dimensions.

It will of course be understood that the auxiliary sections 8 and 9 may both be formed integral with the same main section 5 or 6 instead of as shown in which case both sections 8 and 9, would be bent in the same direction into engagement with the other main section when forming the pulley case. It will also be apparent that the locations of the projections 11 and 12 and the recesses 13 and 14. may be reversed if desired and further that in some instances these elements may be omitted entirely.

Various changes in the specific form shown and described may be made Within Gopies of this patent may be obtained for the scope of the claims Without departing from the spirit of my invention.

I claim:

1. A blank for a pulley case comprising an intermediate section main sections extending therefrom in opposite directions, auxiliary sections extending from said main sections in a direction transverse to the length of the blank and projecting sections forming continuations of said auxiliary sections in opposite directions.

2. A blank for a pulleycase comprising an intermediate section, main sections extending in opposite directions therefrom, projections extending outwardly from oppo site edges of said main sections, auxiliary sections extending from opposite edges of said main sections in directions transverse to the length of the blank and provided at their outer edges With recesses adapted to receive said projections, and projecting sections forming continuations of said auxil iary sections in opposite directions parallel to the length of the blank.

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.
