SASH-HOLDER.

SPECIFICATION forming part of Letters Patent No. 536,729, dated April 2, 1895.

Application filed November 16 1893. Serial No. 491,114. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM LINDEN, of Helena, in the county of Lewis and Clarke and State of Montana, have invented a new and Improved Sash-Holder, of which the following is a full, clear, and exact description.

My invention relates to an improvement in sash holders, and it has for its object to provide a holder of exceedingly simple and durable construction, capable of attachment to any window, and of manipulation whereby a window may be held either in a lowered or in an upper position as required.

Another object of the invention is to provide a sash holder in which the holding or clamping member will be made entirely of a yielding material such as rubber, and to pro vide a means whereby as the bearing surface of the holding or clamping member becomes worn, said surface may be expeditiously and conveniently adjusted to renew its positive contact with the article it is adapted to engage, and to provide a means whereby the sash holder will be of exceedingly simple, durable and economic construction.

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 claim.

Reference is to be had to the accompanying drawings ,forming a part of this specification, in which similar figures and letters of reference indicate corresponding parts in all the views.

Figure 1 is a front elevation of the sash holder. Fig. 2 is a similar View, illustrating the locking device employed in connection with the holder; and Fig. 3 is a vertical section taken practically on the line 3-3 of Fig. 1.

In carrying out the invention, the holder consists of two plates 10 and 11, constructed of metal or other hard or unyielding material, one of the plates having'a handle 12, attached thereto, and a disk 13, solidly constructed of ayielding substance, preferably rubber. The plates 10 and 11, are shown circular in general contour, and such is their preferred shape. The yielding or elastic disk 13 is of greater diameter than the plates 10 and 11, and is placed between the two plates, the plates being one beneath the other and eccentrically located upon the disk. The disk 13 may be termed a clamping disk, as it is the yielding .14 and 15, the said screws being placed ordinarily one at each side of the center, and it will be observed that by tightening the screws the plates will be carried in direction of each other, and will exert such pressure upon the elastic or yielding disk as to increase its circumference. Thus it is evident that should the peripheral surface of the clamping disk become worn, by tightening up the plates 10 and 11 the circumference of the disk may be restored to its original or desired measurement, or substantially so.

The handle 12, is usually connected to or made integral with the lower or under plate 11, and the handle is made to terminate in a knob 16, or its equivalent, whereby it may be readily manipulated. An aperture 17, is eccentrically produced in the plates and the disk, the aperture being centrally located with respect to the plates and disk, yet is placed near one margin of both. In fact, the aperture may be located any desired distance from the center of the plates and disk.

The holder is adapted to be located upon the window sash A, being pivotally connected therewith by a screw 18, or its equivalent,

passed through the aperture 17in the holder and into-the sash. The holder is so placed with relation to the window frame B, that when the handle hangs perpendicularly downward, or is in a perpendicular upper position, the peripheral surface of the clamping disk 13 will be in binding or clamping engagement with the inside of the Window frame, as shown in the drawings. hen the handle 12 is in its upper position, the disk by engagement with the window frame will hold the sash down, and by turning the handle down, or in its lower position, the sash will be prevented from falling down. The holder may be maintained in either of the two positions above named by passing a screw 19, or its equivalent, over the handle 12 and into the window frame, as shown in Fig 2.

This device is exceedingly simple, durable and economic, and is capable of attachment to, or of use in connection with any description of sliding window.

Having thus described my invention, I

the disk, whereby upon drawing the plates together the circumference of the disk will be increased, a handle whereby the plates and disk are conjunctively moved, and a locking screw adapted for engagement with the ham dle and for attachment to an adjacent fixed support, as and for the purpose specified.

WILLIAM LINDEN.

claim as new and desire to secure by Letters Patent-- The combination, with a window sash and frame, of a sash holder consisting of adisk of l yielding or elastic material, plates engaging with opposite faces of the disk and eccentrically located thereon, the disk being adapted for engagement with the window frame, a pivot passed eccentrically through the plates and disk into the window sash, adjusting screws holding the plates in engagement with Witnesses:
