SASH-HOLDER.

SPECIFICATION forming part of Letters Patent No. 306,307, dated June l0, 1884.

Application filed September 2i, 1883.

j?) @ZZ whom t may 0011/067111/ Be it known that I, Josera P. CnN'rNnR, a citizen of the United States, residing at lPittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Sash-Holders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to improvements in sash-holders5a-nd the object is to produce a sash-holder that is reliable at all times, holding the sash in any position desired, which is not liable to get out of order, and can be readily applied to new as well as old windows, and at avery moderate expense.

The invention consists in securing to the n sides of the sash a rack or toothed plate, into the teeth of which a pinion meshes. Said pinion is journaled in a spring, bent at its outer end around the axle of the pinion on both `of its sides, and turned over a pin attachcd tothe sides of a metal box or ease, and bearing with its rear end on a projection or rib on said box. A ilat auxiliary spring attached to the pin assists in forcing the pinion in Contact with the rack.

It also consists in certain dctailsof construction, as will be more l'ully deseribedhereinafter, and more speeically pointed out in the claims, reference being had to the accompanying drawings.

Like letters oi reference indicate like parts in the different -igures ofthe drawings, in uhiel1- Figure ll. represents a side elevation of a window-trame and sashes, partly in section.

Fig. 2v is a vertical cross-section on line a: wol' i Fig. 1. Fig. 3 is an edge view of the sashcs, showing the racks or toothed plates. Fig. 4 is an enlarged sectional view' ot' the box with the )inion and urines. Fig. 5 is a )lan viewv D C l of the same. l

In the drawings, il represents a windowtrame, and li B are the sashcs, made of any required size. To the sides ot' the sashes are secured the racks C C in any suitable manner.

or receptacles a., made of any suitable material, and in them the pinions D D are journlled by means. of a pin, b, and wire spring E. This spring is forked or recessed, and the forked ends embrace the axle c of the pinion on each side. It is then turned around the pin b near its rear end, and bears withthe projecting part on a| cross-bar, d, secured or east to the box a. Between the forked ends ofthe spring Eis arranged a lighter dat auxiliary spring, F, which passes under the pin b. This spring'assists the main spring in forcing the pinion into contactwit-h the rack, so as to mesh with it. The springs may be made of steel, brass, or other metai. rEhe racks and pinions may be made of any suitable material and size, aecordin g to the requirements of the ease.

The advantages of my improved sash-holder will be readily appreciated, and among some of them may be mentioned that it is perfectly l noiseless, it will hold a sash in any position desired, it is automatic in its operation, itis out ot` sight entirely, it is not liable to get out of order, it can be produced at avery reason able cost, and can be readily applied to new as well old sashes and windows.

It will be readily understood that the racks and pinions may be reversed-i. e., the racks may be secured to the frame of the window and the pinions attached, with their casing, to the sashes-\vithout departing 'from the spirit of my invention, although I prefer the arrangement shown and described above.

It' desired, only one rack and pinion may be employed on one side oi' cach sash, instead of using one on each side, although not so good.

The operation is as follows: The pinions are forced into Contact with thetceth ol` the racks or toothed plates, with which they mesh, by means ofthe main spring E, as well as the auxiliary spring F. 'The sash will remain stationary at any desired height until forced up or down bythe person operating it. It will be readily understood that the pinions, being in elastic or yielding bearings, will be forced back when the sash is raised or lowered, and at any point it is stepped the pinions will or" course be forced into Contact with the racks, and by the pressure of the springs on the pinions will securely hold the sash Wherever desired.

IOO

I am aware that ratchets and pawls operatl ing WindoW-sashes are old; also, that ratchetteeth plates and pawls, as Well as cams or ecoentries With teeth or roughened surfaces to form a friction or gripping device, are old, and l therefore disclaim all such; but,

Having thus described my invention, what I claim, and desire to secure by Letters Patent,

l. A sash-holder consisting-of a boX or oasing containing a pinion journaled in a spring secured to a cross-pin, and bearing against a cross-bar, d, substantially as shown, and for the purpose set forth.
