SPECIFICATION forming part of Letters Patent No. 565,849, dated August 11, 1896.

Application filed February 5, 1896. Serial No. 578,120. (No model.) I

To all whom it mag concern:

Be it known that I, ALEXANDER ERKLIN, of New York city, in the county and State of New York, have invented a new and useful Improvement in Window-Frames, of which the following is a full, clear, and exact description.

My invention relates to an improvement in window-frames, or frames for sashes, and the object of the invention is to provide frictionrollers in the sash-grooves of the frame, the said rollers being provided with a yielding or spring support, whereby they will constantly bear upon the window-sashes while the said sashes are within the frame, no matter whether the sashes be in a lower or in an upper position.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming apart of this specification,

in which similar characters of reference inclicate corresponding parts in all the figures.

Figure 1 is a front elevation of a windowframe containing sashes, the frame having the improvements applied thereto, and a por tion of the frame being in section to disclose one set of friction-rollers. Fig. 2 is a vertical section through the window frame, taken practically onthe line 2 2 of Fig. 1. Fig. 3 is a section through a portion of the windowframe, the said section being taken at right angles to the section shown in Fig. 2, and substantially on the line 3 3 of the latter figure. Fig. 4 is a detail view of a portion of the upper or fixed section of the window-sash stop.

Fig. 5 is a perspective view of the removable for engagement with the inclined surface of the abutting section; and the removable section of the parting-strip B is fitted in a suitable groove 13, made in the frame, as shown best in Fig. 2.

The division in the parting-strip B is so made that when the upper and lower sashes G and D are in their closed position the connection between the two sections of the parting-strip willbe at or near a point above the upper edges of the meeting-rails of the said sashes. One of the inner-sash stops E is preferably made in two sections, an upper section 14 and a lower section 15. The upper section 14 may be secured to the frame in the usual manner, and where the two sections of the outer-sash stop connect their opposing faces 16 are correspondingly beveled, and also the connection between the two sections of the sash-stop is made preferably at or near a point horizontally opposite to the connection between the sections of the parting-strip B- The lower removable section 15 of the innersash stop is provided with a groove 17 in its 'upper edge, as illustrated in Fig. 5, the said groove being adapted to receive a web 18, preferably of metal, which is ordinarily in the central portion of the lower face of the upper or fixed section 14, and in addition to the locking engagement thus made between the opposing ends of the two sections of the sash-stop the lower removable section of the sash-stop E is usually provided at or near its lower end with a bolt 19, or its equivalent, adapted to enter a suitable keeper in the sill of the window-frame.

In order that the sashes may be raised and lowered with the least possible amount of resistance, and, furthermore, inorder to prevent the sashes from having a rattling move ment in the window-frame, I provide for each window-sash at each of its sides a tension device F. Each tension device comprises a face-plate 20, having openings 21 at each side of its center, through which extend portions of the peripheries of friction-rollers 22. These friction-rollers are ordinarily pivoted in horizontal brackets or hangers 23, and the hangers are secured to the end portions of a spring 24, the said spring being secured at or near its center, preferably upon the inner end of a post 25, projected from the inner surface of the face-plate 20 about midway between the friction-rollers 22. Two of these tension devices are located at each side of the window-frame, one being placed in each of the sashgrooves, and the location of the tension devices is such that when the lower sash is in its closed position one of the rollers of each tension device belonging to that sash will be above the upper face of the upper rail of the sash, the lower rollers engaging with the side edges of the sash, and when the upper sash is in its upper position one roller of its tension device will be in engagement with the sash and the other below it, so that no matter how the two sashes are moved in the window-frame they will be in engagement With the two friction-rollers, one at each side. The tension devices are located in suitable recesses 26, made in the sashgrooves, the outer portions of the said recesses being closed by the face-plate 20 of the said tension devices.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with a window-frame,

of tension devices adapted for engagement with the sashes, the said devices being located in recesses produced in the back wall of the sash-grooves of the frame, each device comprising an apertured face-plate, having a central support on its rear face, a spring secured to said support at the center of its length, and friction-rollers attached to the end portions of the spring, a portion of their peripheral surfaces extending through an opening in the face-plate, as and for the purpose specified.

2. A tension device for windows, consisting of a face-plate having an opening near each end and provided with a post projecting from its rear face, a spring secured at the center of its length to the post, brackets on the ends of the spring, and rollers mounted in the brackets and projecting into the openings of the face-plate, substantially as herein shown and described.
