IMPROVED SASH-FASTENER.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that I, HENRY B. SNYDER, of Cherry Grove, Hamilton count-y, State of Ohio, have invented certain new and useful Improvements in Sash-Fasteners; and I do hereby declare the following to be a sufficiently full, clear, and exact description thereof to enable one skilled in-the art to which my invention appertains, to make and use it, reference being had to the accompanying drawings, making part of this specification.

The nature of Tuy-invention consists in so combining a spring-key with a spring-pawl, which acts upon a' ratchetwheel secured to one of the rubbertired rollers of a window-sash, that the sash can be supported at any desired point in the frame, and yet, by a slight pressure on the head of the key, admit of the lowering of the saine, as hereinafter more fully described,

In thel accompanying drawings- Figure l is an elevation of a window-sash, partly sectioned,'in which my rollers and frames are secured.v

Figure 2 is a detached perspective view ot the combined rubber-tired roller, catch-device, and releasingkev.

Figure 3 is a view of a roller and frame without the catch-device.

' A is an ordinary window-sash. the combined roller and catch at the lower right-hand corner, and the plain rollers, iig. 3, at the other. corners.

'lhe rollers B have rubber tires or thick bands, C,A

firmly secured to their peripheries, and are suitably journalled in the frames D, which are secured to the sash by common screws, as shown.

4The roller E is similarly jonrnalled in the frame F, and is provided with rubber tire G.

To this roller a ratchet-wheel, H, is secured, into which the spring-pawl I engages.

I prefer to attach y This device, by permitting the roller E to revolve in but one'direction, sustains or supports the sash when raised, and will not permit it to fall unless the sp'ring-pawl is released.

To release this, I provide the key K, whichI yslides through the plate L, the latter being secured to the insideiof the sash, as shown.

Ooiled spring M, between the plate Land the collar N, on the key K, serves to keep theond of the keyy always against the spring-pawl.

lhe keyK is provided with a head, k, for the thumb or nger of the operator to act against in releasing the pawl. y The rubber tires of the rollers, when the rollerrames are in place, project so far beyond the face ot' the sash-sides, that when ther sash is forced into place within its frame, the rubber is tightly compressed, and thus serves to prevent the sash from rattling loosely in the frame.

The rubber onroller E, inasmuch as the roller cannot revolve (when the catch is engaged) in such a direction as would be given it when the frame-is falling, serves, by pressure on the sides of the frame, to act vas a brake, and thus support, in almost any desired g position, the weight of the sash.

I claim herein as new, and of my invention- .The spring-key K, arranged to operate directly upon spring-pawl I, in combination with ratchet-wheel H and rubber-tired roller E, arranged to operate substantially as and for the purpose set fortl'i.

In testimony of which inventiou,l hereunto set'myhand.4
