IMPROVEMENT IN sAsH-HoLDERs.

The Schedule referred to these Lett-ers P atent and making part of the same.

To alt whom Ait may concern .Beit known that I, JOHN F. DLN'GEE, of Bedford Station, in the county of Vestchester and State of N ew York, have invented a new and improved Window-Regulator; and I do hereby declare that the following' is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the saine, reference being had to the accompanying drawingforming part of this specification.

MyA invention relates to sash-holders, and consists in the improved combination of parts hereinafter described, and more particularly pointed out in the claim.

The drawingr represents a vertical section of the sash-regulator, showing the parts of which it is composed, and the manner of its application and operation.

A represents the window-sash in red, and as seen in the drawing the lock is applied to its edge as when holding it'up.

B is the case or frame of the lock.

C is the roller, which is attached to plates D by a central pivot, e.

F is a ratchet, lwhich is attachedvto'the roller C and is revolved with it.

G is a triangular-hooked ratchet-pawl, which is also attached to one of the plates D by pivot at h.

rlhe plates D are pivoted to another movable plate, i, through .which plate the screw J passes, and in which it works.

The screw is fixed as regards its longitudinal mo-` tion, oneoil its bearings upon which it revolves being in the vertical bar o, and the other, or its end, having a bearing in the frame B, as secn in the drawing at p.

It will be seen that, as the screw works inthe plate or stud i, upon revolving or turning the screw the plate D and the roller will be moved out or in, and

thereby the roller will be made to bear more or less against the sash. This adjustment is necessary to adapt the lock to sashes of di'ereut size or weight.

When the sash is being raised the hooked pawl Gr will not act on the ratchet to hold it, as seen, as at a certain point the ratchet is thrown out of reach of the pawl; but when the-weight ofthe sash brings the down pressure on the roll the 4ratchela-teeth are thrown into the hooked pawl, as represented in the drawing. lhe roller C is made of rubber or some elastic ma 'ter-ial, so as to create the necessary frictionwhen it is pressed against the sash. Being prevented by the ratchet and pawl from turningwhen presseddowm' ward by the sash, the friction thus created holds the sash in any desired position.

'n is a spring, which bears against the pawl to press it down so as to engage with the ratchet, as seen.

This sash-regulator may be applied to the sashes of any window, thus aiording all the conveniences for sustaining the sashes in any desired position that can be derived fromthe expensive box window-frame with its weights, pulleys. and cords:

Having thus described my invention,

I claim as new-and desire to secure by Letters Patent- A The pivoted roller C, ratchet F, and spring-hook pawl G n, combined as described with pivoted plates D, movable plate i, and swiveled scre'w J, for the purpose specified. l

JOHN DINGEE.
