FASTENER FOR MEETlNG-RAlLS OF SAS HES SPECIFICATION forming part of Letters Patent No. 297,605, dated April 29, 1884. Applisation filed February 1, 1884. (Model.)

To all whom it may concern:

Be it known that I, OLIVER S. J 131), a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Sash-Fasteners, of which the following is a specification.

My invention relates to improvements in sash-fasteners of the class shown in my Patent No. 50,136, September 26, 1865. The

' principal object of my invention is to improve upon said sash-fastener so that it will not easily get out of order by becoming bent in use. I attain this object by the construction illustrated in the accompanying drawings, in which- Figure 1 is a plan view of my improved sash-fastener; Fig. 2, a side elevation of the same. Fig. 3 is a vertical section thereof,- partly in elevation on line m of Fig. 1. Fig. 4 is a plan view of the half of my sashfastener which is designed to be applied to the upper rail of the lower sash. Fig. 5 is aplan view of the locking-lever. and cam.

In the accompanying drawings, A desig.

nates the part of my sash-fastener which is applied to the lower rail of the upper sash, and'it consists of the latch a, having slotted stud c for engaging with the locking-lever e,

with solid trunnions to journal it with the I receive said stud, and provided with a lock- 100 and of the base-plate b and spring h, Fig. 3. This hereinbeforedescribed part is, with the exception of the slotted stud c, the same as has heretofore been manufactured by me.

13 designates the part of my sash-fastener that is designed to be securedto the upper rail of the lower sash, and consists of the keeper (2, the lever e, and integral therewith the Cam f. The keeper presents a fiat and smooth surface on top, and is provided with the orifice g for the reception of the slotted stud c. The lever e and integral cam f are placed within the keeper, after which the under side of the keeper is covered by a plate, a, and a rivet is passed through the hub of the cam and lever and headed upon its under side to secure the plate a and to journal the lever in place. If desired, instead of this rivet and a hole through the hub of the lever, the lever may be provided keeper and the platen. In addition to the curve at the edge of the cam, as shown by .plan view, Fig. 5, the cam is made thinner at its forward part, and gradually thickens on its under side, as shown by the side elevation, Fig. 3. The shank of the lever works in a slot in the front edge of the keeper, and its handle rises upward a little, but not quite so high as the middle upper surface of the keeper. The advantage of this construc- .tion is that when the lower sash is thrown up far enough to strike the window-frame the fiat upper surface only will come in con tact with the frame, and therefore there is no liability of bending the lever or otherwise injuring the parts. Furthermore, this upper surface of the keeperis so broad that it will not indent the window-frame and form a depression in it, as will a pointed knob or stud. As shown in the drawings, the cam f is underneath the upper shell of the keeper; but, ifdesired, the cam might be placed on top of the keeper, and in that event the cam itself might constitute the rivet-head, by which the lever and plate aare secured, care being taken to drive or otherwise secure the rivet within the hub of the lever, sothat the cam will necessarily move with the lever the same as if it were moved integral therewith.

I operate my device as follows: To look the sash, I turn down the latch a, so that the slotted stud 0 will pass through the orifice g in.

the keeper d, and by then swinging the lever e and its cam f to the left said cam will engage the slotted stud 0, thereby drawing the latch down into the keeper and drawing the meeting-rails together, firmly looking it thereto. When I wish to unfasten the sashes,-I have simply to move the lever and 'cam to the right and out of engagement with the slotted stud .0, when, by means of the spring h, the latch a is raised up out of the way of the lower sash, and is held there by said spring, as indicated by the broken lines in Fig. 2.

I claim as my invention 1. The herein-described sash-fastener, consisting of the spring-pressed latch having the slotted stud, the keeper having orifice g to ing-lever and cam for engaging said slotted stud, substantially as described, and for the purpose specified. I

2. In a sash-fastener of the class described,

5 a chambered keeper having a fiat upper surface containing a slotted orifice, and provided with a locking-lever mounted within the chamber, substantially as described, and for the purpose specified.
