NORMAN B. HURD, OF NEW BRITAIN, CONNECTICUT, ASSIGNOR TO THE RUSSELL da ERWIN MANUFACTURING COMPANY, OF SAME PLACE.

FASTENER FOR THE IVIETING-RAILS OF SASHES.

SPECIFICATION forming part of Letters Patent No. 471,553, dated March 29, 1892.

Application lecl February l, 1892. Serial No. 419,871. (No model.)

To all whom t may concern.-

Be it known that I, NORMAN B. I-IURD, a citizen of the Unites 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.

In the accompanying drawings, Figure 1 is a plan view of my fastener, together with the meeting-rails of the sash. Fig. 2 is a vertical section of my fastener on the line @c of Fig. 1. Fig. 3 is a vertical section of the same on the line y y of Fig. 1. 'Fig. 4 is a plan view of the base-plate and sliding latch. Fig. 5 is a plan view of the pin-plate. Fig. 6 is an edge view of said plate. Fig. 7 is a plan view of the lever, and Fig. 8 is a reverse plan view of the cap.

The base-plate A is designed to be secured to the upper rail B of the lower sash, while the keeper C is designed to be secured to the lower rail of the upper sash. This keeper is provided with a pin or post9 of any ordinary form for being engaged by the hook of the sliding and swinging latch 10, substantially as in ordinary fasteners of this class. In the center of the base-plate A, I attach a pivotal post 1l, which .may be Vsecured to this plate in any ordinary manner-as, for instance, by means of a screw 12. The base-plate is also provided with lugs 13 and 14. The latch 10 rests immediately upon the base-plate. It is provided with a slot 15, through which the V pivotal post 11 extends, and with a narrower slot 16 at the heel of the latch, as best shown in Fig. 4. The heel of the latch is rounded, as shown, the curve on the right-hand side of the narrower slot 16 being on a larger radius than the curve at the lett-hand side, whereby a shoulder 17 is formed at the heel of the latch at one end'ot the lesser curve, while another receive the pivotal post 11 and a pin-hole 25 at one side of the same, as shown in Fig. 7. The pin-plate lies between the lever and latch, (its contour as it lies over the latch being indicated by broken lines in Fig. 4,) with the pivotal post 11 passing through its slot and with its pins 2O and 22 resting, respectively, in the pin-holes of the latch and lever, whereby said plate is pivoted at one point to said lever and at another point to said latch. The

portions immediately surrounding the pivotal post 11 are covered by a cap 26, and the elliptical contour of the pin-plate is to enable it to oscillate within this cap. Between the under side of the cap and the head of the lever is a frictional spring 27 to create a slight friction between the parts; but such spring is not essential to the operation of 4the fast ener. The cap 26 is notched or recessed on its edge, as at 28, Fig. 8, for the projection of the lever and also partially cut away, as at 29, Fig. 8, to accommodate the projecting end of the latch. This cap moves with the latch the same as it :integral therewith, and aside from forming a cover and chamber for the frictional spring its. uses are ornamental rat-her than functional. s

In Figs. 1, 2, 3, and 4 the parts are represented in their locked position. As the lever 23 is turned to bring its handle to the front., the pin-plate acts through its pins to move the latch lengthwise outwardly in a radial dip p rection from the position shown in Fig.4 into a position where its curved portlon between the shoulders 17 and 18 is inside of the inner versed, the parts all moving together until the movement ot the latch 10 is arrested by the shoulder 17 at the point of the heel coming in contact with the stop-lug 14. The further movement of the lever from directly in front to the position shown in'Fig. 1 operates the Ioo pin-plate to draw the latch radially inward again into the position shown in Fig. 4, with the narrower slot 16 drawn over the lug, 14 to iirmly lock the latch in this position. The inner edge of the stop-lug 14 and of the guiding-lug 13, against which the curved edges of the heel of the latch bear, serve to guide the latch and support it as it swings about the axis of the pivotal post.

By my improvement the parts are of simple and easy construction, whereby the fastener is produced at a small cost. By the einployment of the pin-plate between the latch and the lever the operation of the fastener is not only certain and effective, but'the parts work very smoothly and easily.

I claim as my invention- 1. rThe combination of a base-plate, the slidby a pin to said pin-plate, substantially as de` scribed, and for the purpose specified.
