UNITED STATES PATENT OFFICE.

CHARLES A. BRINLEY, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE AMERICAN PULLEY COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PENN- SYLVANIA.

HOUSING FOR SASI-I-PULLEYS.

Specification of Letters Patent.

Patented July 21, 1908.

Application filed December 30, 1907. Serial No. 408,504.

To all whom it may concern:

Be it known that I, CHARLES A. BRINLEY, of Philadel hia, in the county of Philadelphia and tate of Pennsylvania, have invented certain new and useful Improvements in Housings for Sash-Pulleys, whereof the following is a specification, reference being had to the accompanying drawings.

My invention is particularly available for use in connection with sash pulleys, and hence in said drawings, I have illustrated it in that embodiment and in a preferred form as to certain structural details.

Figure I, is a side elevation of such a sash pulley. Fig. II, is a vertical transverse section on the line II, II, of Fig. I. Fig. III, is a horizontal section on the line III, III, of Fig. I. Fig. IV, is a view in perspective of one of the housing-pieces which are secured to the face plate.

The object of my invention is to provide a sheet metal housing for such a structure as a sash pulley, the elements of which can be economically pressed or stamped from sheet metal and easily assembled, and which shall possess great strength, as well as a desirable external finish.

Generally speaking, the present invention is, in some respects, in the nature of an imrovement upon the device set forth in etters Patent of the United States No. 828,699, dated August 14th, 1906, since in its preferred form it utilizes an element set forth in said patent. The organization about to be described, however, affords a much more eflicient means for securing the parts together, so that the tilting or displacement of the housing-pieces is eflectually prevented.

In the drawings, 1, represents the pulley member, mounted upon a headed stud or axle 2.

3, indicates the housing member, and 4, the base member. The housing member consists preferably of two similar pieces of sheet metal, one of which is shown in perspective in Fig. IV, the line of division of said two housing-pieces being upon the long axis of the housing.

Each housing-piece has inwardly turned end portions 6, with vertical edges adapted to meet the corresponding edges of the other piece, and form a close joint therewith, and also having along its lower edge a recessed Patent No. 828,699, dated August 14th,

1906; that is to say it may comprise a front member 13, which I term the face-plate, and a back member 17, which I term the backing-plate, having aninterposed circumferential spacing flange 18, which in the instance shown, is represented as integral with the backing-plate.

The face-plate is provided with raised sockets 16, which fit snugly within countersunk sockets 19, on the backing-plate, and

the two plates are secured together, by upsetting or riveting the edges 15, of the sockets 16, over the edges of the sockets 19. The apertures of said sockets afford openings for screws, whereby the device may be secured to the window frame.

The base is provided with an elongated central opening adapted to receive the edges of the housing-pieces, and when the tw0-part base is employed, I construct the openlng in the backinglate of slightly larger dimensions than t e corresponding opening, in the face-plate, the configuration 0f the two openings, however, being similar. I At the sides of the opening in the backingplate are two raised integral flanges 20, whose dimensions are such that they will fit snugly within the recesses beneath the shoulders 8, formed along the flat central portions of the housing-pieces.

The two housing-pieces with their vertical edges in juxtaposition, are inserted in the opening of the base, and, since the edge of the opening in the face plate extends beyond that of the backing-plate, the bottom edges of the housing-pieces will rest upon the inner surface of the faceplate, while the shoulders 7, rest upon the surface of the backing-plate. The housing 55 portion forming shoulders whose outlines are 1 pieces are secured to the said flanges 20,

preferably by electric welding, the regions of Welding being indicated conventionally by the circles at 21, in Fig. I, and by the upsetting or heading it at the opposite ends,

so as to clamp the two housing-pieces firmly together.

I prefer to employ the two-part base above described, since it gives great rigidity to that portion of the structure, and

3 also conceals the bottom edges of the housing-pieces. But, obviously, a single thickness of metal, such as the backing-plate alone, Without the flange 18, might be employed for the base, the edges of the housingpieces below the shoulders 7, being of such depth as to be flush with the bottom surface of the single plate. It is also'obvious that the housing members may be formed of a single piece of metal bent back upon itself and having vertical edges adapted to meet at only one end. Such modifications of detail are entirely consistent with the features in which my invention resides.

Having thus described my invention, I wish it to be understood that I, of course, do not claim any of the features set forth or described in Letters Patent No. 828,699, above referred to.

1. The combination of a base member, having an elongated opening with raised flanges along its sides; a housing member having a bottom edge fitting snugly Within the opening of the base and having recesses on its sides adapted to receive the raised flanges of the base; means for securing said housing member to said flanges; shoulders adjacent to the ends of said housing member, adapted to rest on the surface of the base; a pulley; and an axle therefor secured to said housing member.

2. The combination of a base, comprising a face-plate having an elongated opening and a backing-plate having an elongated opening of similar configuration but of larger dimensions, and having raised flanges along the sides of said opening; means for securing the face-plate to the backing-plate; housing-pieces having shoulders at the end portions adapted to rest upon the corresponding portions of the opening in the backing-plate while permitting the edges of the housingpieces to abut against the inner surface of the face-plate, said housing-pieces also having recesses, along the sides, adapted to receive the .raised flanges of the backing-plate; means for securing said housing-pieces to said flanges; a pulley; and an aXle therefor secured to the housing-pieces.

In testimony whereof, I have hereunto signed my name, at Philadelphia, Pennsylvania, this twenty-seventh day of December 1907.

CHARLES A. BRINLEY.
