E. 0. STEARNS. SASH CORD GUIDE.
No."496,069. A Patented Apr. 25, 1893.
UNITED STATES PATENT OFFICE.
EDWARD C. STEARNS, OF SYRACUSE, NEW YORK, ASSIGNOR TO E. O.
STEARNS & 00., OF SAME PLACE.
SASH-CORD GUIDE.
SPECIFICATION forming part of Letters Patent No. 496,069, dated April 25, 1893.
Application filed October 28, 1891. Serial No- 410,109. (No model.)
To all whom it may concern:
Be it known that 1, EDWARD O. STEARNS, a citizen of the United States, residing at Syracuse, in the county of Onondaga and State of New York, have invented a new and useful Improvement in Sash-Cord Guides, of which the following is a specification.
The objects of this invention are to simplify the means whereby the casing of the sash cord guide is secured in the window frame and the devices whereby the centers are marked for the auger holes which form the mortise in which the casing is secured.
In the accompanying drawings: Figure 1 is a side elevation of a sash cord guide provided with my improvements showing the same secured in a window frame. Fig. 2 is a front elevation thereof. Fig. 3 is a plan view thereof. Fig. 4 is a horizontal section in line c% Fig. 1. Fig. 5 is a vertical transverse section in line y-y Fig. 1. Fig. 6 represents a prepared blank from which my improved casing is formed.
Like letters of reference refer to like parts in the several figures.
A represents a rectangular blank of sheet metal from which the casing is formed by bending the blank midway of its length. The blank is provided at its ends with a tenon a and a recess 1) which interlock with each other and retain both ends of the casing in alignment. The sides of the casing have the form ofa series of tubular swells or intersecting cyl lnders c to permit the mortise D in the window frame d, which receives the casing, to be made by a series of intersecting auger holes.
6 represents a rivet arranged transversely in openingsf formed centrally in the sides of the casing and which prevents the sides of the casing from spreading and serves as an arbor on which the grooved pulley G turns. The face of the casing may be provided with a narrow flange h which engages against the outer side of the window frame and limits the inward movement of the casing;
I represents spurs projecting laterally from the sides of the casing with their pointed ends toward the face thereof and which serve to hold the casing in its seat. These spurs are stamped out of the casing by forming V- shaped slits in the blank, as represented in Fig. 6, and then bending them slightly outward so that the spurs project obliquely toward the face of the casing. Upon driving the easing into its seat, the spurs yield as they are somewhat elastic but embed themselves into the wood and resist any force which tends to draw the casing out of its mortise, thereby holding the casing firmly in place withoutthe use of any additional fastening device. This means of securing the casing in the mortise avoids the use of face plates or ears on the casing and of fastening screws passing through such face plates or ears and constitutes an extremely simple and reliable fastening device. The spurs are preferably arranged equidistant and on the summits of the tubular swells of the casing,'so that they can be used for marking the centers for the auger holes which form the mortise for the casing.
My improved sash cord guide is very simple and inexpensive in construction and can be securely applied to a window frame in a very simple and expeditious manner.
I claim as my invention- A sheet metal pulley casing having a flexible or elastic pointed locking spur struck out from the metal of the casing,'such spur overlying an opening in the casing and free except at its base where it is united to the easing, substantially as set forth.
WVitness my hand this 14t-hday0f October, 1891.
EDVARD C. STEARNS.
