SASH-LOCK.

SPECIFICATION forming part of Letters Patent No. 228,471, dated June 8, 1880.

Application filed October Q5, 1379.

To all whom it may concern:

Be it known that we, SPARROW M. NICKER- son and .latins P. TANsEY, or' Chicago, in the county of Cook and State of illinois, have invented certain new and useful Improvements in Sash-Locks, which. are fully described in the following specilication, reference being had to the accompanying drawings, in which- Figure l represents a vertical section of a window frame and sash with our improved sash-lock applied; Fig. 2, a detailed transverse section taken on line x oc, Fig. 1; Fig. 3, a front elevation of our improved fastening' for lthe upper sash of the window; Fig. 4, a rear elevation ofthe same 5 Fig'. 5, a sectional elevation taken online i/ y, Fig. 3, Fig. 6, a front elevation of our improved fastener for the lower, sash 5 Fig. 7, a vertical section of the same, taken on line e e, Fig. 6; Fig. S, a perspective view, showing a modification in the construction and arrangement of some parts of the fastening; Fig. E), a rear elevation of the same; Fig. 10, a perspective view oi' one of the thumb-pieces shown in Fig. S; Fig'. ll, a plan view of one of the dogs used with the same; and Fig. l2, side and end elevations of the holder by means of which the lower end of the fastening-rod is secured in place.

Our improvements herein described and shown relate to sash-fasteners belonging to that class in which a rod is used, on which dogs or catches are made to bite, and especially to that division of this class of fastenings in which the dogs are fastened to the window-frame and the rod to the sash-frame, so as to move with the latter.

Our invention consists in certain special devices and combinations of devices, all of which will be hereinafter more fully described, and pointed out definitely in the claims.

In the drawings, A represents a windowframe; B, the lower', and B the upper, sash. To each of the sash-frames is applied a rod, C, fitted in a groove, I) or b', in the edges of the respective sashes at one side of the window. These rods are inserted in the sash-frames by means of bends c at each end thereof, and one end, preferablyr the lower, is held in a keeper of such construction that it may be readily removed therefrom. This keeperD is a tubular piece of metal. with a screw-thread formed upon its outer surface, by means of which it is held in a socket provided for it in the sashframe. The tubular opening in this socketpiece is adapted to receive the bent end of' the rod, in which it is readilyinserted, and from which it is easily removed, so that the rod may be detached from the sash with great ease when the latter is removed from the window-frame, but is held in place when the sash is in place.

For the fastening for the upper sash we provide a shield or keeper, E, which is fastened to one side ol" the frame, and has a long arm, c, projecting out at one side thereof sufficiently to extend along the side of the windowframe and'project outside of the stop-bead a thereon. This arm ends at its outer extremity in a thumb-piece. c. This keeper is let into the side of the frame so as to be flush therewith. 1 Upon the outer face of thev body or main portion of the keeper a lug, F, projects, which is perforated, and receives the rod attached to the sash-frame, as shown in Fig. 3 of the drawings. Two smaller lugs, j', also project from the same face ofthe keeper on each side of the lug F, and are provided with notches f', which receive the rod and steady the movement of the latter. Just underneath the lug F is an opening, c2, in the keeper, and the bent inner end of a dog, G, projects through this opening, and is provided with a perforation, g, through which the sash-rod passes. This dog is arranged behind the keeper, as shown in Fig. 4 of the drawings, the inner end being held loosely between a curved or bent lug, H, on the back of the keeper just below the central opening therein, and a straight lug, 7L, above the saine, while the outer end rests upon a lug, h', at the outer end of the arm c, and is bent around in front oi' the latter, terminating in a thumb-piece, g.

A spring, I, is arranged on the sash-rod between the biting' end of the dog and the lng F. In this fastening, as it is only necessary to secure the upper sash from falling-that is, fastened in any one directionit is only necessary to have the one dog above described.

The principal operation is the same as usual in this style of fastening; but it will be noticed that the dog is not secured to the keeper in any fixed position, but is loosely held thereto when the keeper is fastened to the window-frame, and is permitted to have a certain amount of motion besides the ordinary rocking motion which would be necessary to relieve the sash-rod from its bite. This permits the dog to lit itself to the sash-rod with readiness and with such latitude of motion that the operation of the fastening is made certain, and does not depend upon a certain fixed position of the dog, as is the case when the latterl is mounted on a pivot in a fixed position. This also prevents the fastening from becoming useless by the wea-rin g of the dog in service.

The fastening ofthe lower sash is constructed upon the same general principle; but as it is desirable to be able to lock the lower sash in both directions-that is, so that it can be neither raised nor lowered-two dogs are employed, as shown in Figs. 6 and 7 of the drawings, one being arranged above and one below the central lug, F, on the keeper. The lug h on the back ofthe keeper is also arranged between the inner ends of the dogs, and of course there are two bent or curved lugs, H,

one above the upper dog and the other below the lower one, as shown in Fig. 7 of the drawings. The spring I must also be duplicated.

le have also provided a device for preventing the sudden dropping of the sash when the bite of the dogs on the si sh-rod is released. This device is in the nature of a frictional stop operating on the rod to prevent thc sash from dropping with its own weight, but at the same time yielding to permit the latter to be drawn down upon the application of slight force.

The stop consists of a conical washer, K, made of leather, rubber, or any other material, and placed in a conical seat, 7.7, in the lug of the keeper, through which the sash-rod passes. This washer is perforated to permit the sash-rod to pass through it, and is arranged with its-smaller end downward, as shown in Fig. 7 ofthe drawings.

It will be evident that the downward movement of the sash-rod will tend to pull the washer into its conical scat, thereby pinching it up tighter on the rod, and so preventing the dropping of the sash. `At the same time, as the washer is made of elastic material, it yields readily to permitthe sash to be pulled down with the exertion of but little force. The washer is held in place by the spring above it and between it and the end of the dog. This frictional device may be applied to the fastening of either the upper or lower sash, as may be desired. The change necessary to apply it to the upper fastening, dcscribed above, will be obvious to any ordinary mechanic.

It may sometimes be desirable to arrange the outer ends of the dogs and keepers within the stop-bead, and in Figs. 8 and 9 'We have shown a modification of our fastening adaptingit to this purpose.

It will be noticed that the outerl` ends of 7o the dogs are cut off and formed to suit separate thumb-pieces L, which, at their inner ends, are provided with slits or recesses l, in which the outer ends of the dogs are loosely fitted. The outer ends of the dogs are intended to reach only to the stop-bead.

The thumb -pieces are arranged at right angles to the ends of the dogs, as shown in Fig. S ot' the drawings, and are let into the inner edge of the stop-bead, and are held by a keeper, M, which is fastened to the latter. This keeper M may have a thumb-stop, n, cast with it, with a projection ou the back side thereof, connected by a loosejoint to the end ofthe keeper E.

The principle of construction and operation, it will be noticed, however, is precisely the same as when the fastening is constructed as above described, and shown in the other figures ot' the drawing..

Other changes may be made in construction and arrangement of some parts ot' the fastening to adapt it to different locations without changing the principal operation, and the friction-stop may be employed with this fastening or not, as may be desired, and may also be applied to fastcnings differing in construction from that herel described.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. The combination, with a keeper attachcd to the window-frame and provided with a lug, through which the sash-rod passes, of a pair of dogs loosely connected to the keeper by means of lugs, substantially as dcscribed, and perforated at their inner ends to receive the sash-rod, whereby the windowsash is held and prevented from movement in either direction, as set forth.

2. A keeper', E, provided, as described, with lugs F andfon its front face and H h on its back face, as described, in combination with the dogs G, held loosely to the keeper by means of the back lugs and the sash-rod, a spring or sl'nings, I, and the sash-rod C, substantially as described.

In a sash-fastener,a sash-rod, in combination with biting-dogs, through which the rod passes, and a frietional stop acting on a rod to prevent the dropping of the sash when released from the dogs, substantially as described.

4. The sash-rod C, in combination with the conical elastic washer, conical seat k for the latter on the keeper, and one or more dogs or locking-catches, G, substantially as described.
