:SPECIFICATION forming part of Letters Patent No. 311,872, dated February 10, 1885.

A ppliention filed May 2l, 121184.` (No model.) I

To all whom it may concern:

Be it known that I, NORMAN CLARK, a citizen of the United States, residing at Sterling', in the county of Whiteside and State of Illinois, haveinvented certain new and useful Improvenients in Sash-Fasteners; and I do hereby declare thcfollowingto be a full,clear,and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Myinvention pertains to sash-fasteners; and it consists more especially in the provision ot' two mutually-pivoted jaws provided at their outer ends with a rubber or other cushion to prevent abrasions of the window-frame, and

tail.

A is the sideof the window-sash to which the fastener is attached.

is the adjacent window frame, at right angles to such sash, and against which frame the impinging ends of the fastener are in contact.

C C are jaws adapted to be mutually pivot- Y ed at their centers, and having their ends divergent. The outer orimpinging ends of the jaws C are furnished with a rubber or other pliable impacting-cushion, D, so as not to mar or abrade the contiguous face of the windowframe B. I

E is a screw which, passing through the holes a in the jaws C C into the sash A, forms the pivot for the jaws C C.

F is a washer having holes b b, one end of which is placed under the head of the screw E, and the other end of which is attached, by nieans of a screw, G, to the sash A between the inner ends of the jaws C.

H is a spring which is bent or coiled at or near its central portion around the screw G, and the free ends of such spring respectively press outward against the inside of the inner end of the jaws G C, thus holding the opposite or outer ends of such jaws ,in contact with the frame.

It will be observed that the jaws G are withdrawn-from contact with the frame B and the sash thus released by the operator elasping the inner ends of the jaws C be tween his thumb and finger and pressing such ends together. If one end of thespring His weaker than the other, but one jaw 'C might be actuated and the fastening not entirely released. To obviate this I place the screw G in such relation to the adjacent faces of the jaws C that when the latter are pressed together they strike such screw G before they come in4 contact with each other, so that if in compressing such jaws one ol' the latter is actuated so easily as to be moved toward theV other while thelatter remains stationary, directly after such moving-jaw has been withdrawn from the frame B it will be stopped by the screw G, when the further compression will withdraw and release the opposite jaw G. Thus the certain withdrawal of both jaws is assured. It will be seen that the outer ends of the jaws C C, by being bent or deflected, respectively, up and downthe frame B, when in'contact with such frame lock the sash from both upward and downward movement. The washer F serves as a brace for the screw E, and therefore a smaller screwE can be used,

and the sash less punctured than if such screw were required to alone sustain the pressure upon it, and such washer also assists the pivotal action of the jaws C, as otherwise the head of the screw E would be sunken in the jaw G and increase the friction.

The screw G serves a triple purpose of an attachment to the washer F, a seat for the spring I-I, and a stop for the jaws C.

Myy invention has the advantages of being simple in construction, easily put in place,

durable, requires no cutting of the frame or sash, causes no abrasions, and locks the sash at any desired point against both upward and downward movement, and acts automatically.

Vhat I claim as myinvention, and dlesire to secure by Letters Patent of the United States, 1s-

In a sash holder, the jaws C C, furnished with the holes a, through which, by means of the screw E, such jaws are pivotally attached to the sashl in such relation to the windoW- for the pivot E, substantially as shown, and ro frame as that the outer ends of sueh jaws will for the purpose described. respectively engage the side of suoh frame In testimony whereof Iafx my signature in above and below the pivotal point E, such presence of two Witnesses.

` 5 outer ends of the jaws C beings` held in Work- T ing position by the spring H, seated on a LORMAN CLARK' screw, G, serving as a central stop for the in- Vitnesses: ner ends of such jaws, and also, by means of VALTER N. HAsKELL, the double Washer F, servingas an outer brace V. S. FERGUSON.
