FASTENER FOR MEETING-RAILS OF SASHES.

SPECIFICATION forming part of Letters Patent NO. 366,756, dated July 19, 1887.

(No model.)

To all whom, it may concern:

Be it known that I, GEORGE L. BARNES, of the town of North Haven, in the State of Con necticut, have invented certain new and useful Improvements in Fasteners for Meeting-Rails of Sashes, ofwhich the following is a specification.

My invention relates to a fastener for the meeting-rails of sashes, and has for its object to provide a sash-fastening device adapted to simultaneously clamp the meeting-rails snugly together and force the respective sashes tightly to their seats against the horizontal parts of the wi ndow-jamb, with the fastening-arm positively secure from unlocking, except by the movement of the operating-handle, whereby thesashes are held closely shut and secure from rattling, and cannot be unfastened from the outside of the window or by jarring action.

The invention consists in the novel arrangement and construction of an obliquely-journaled fastening-arm, which is adapted to swing on an incline into the plane of the upper sash to engage the holding-hook and draw axially to seat and clamp the sashes together, an operating-handle journaled concentrieto and adapted to actuate the arm by the coaction of a radial pin and spiral cam on the respective parts, and a base-plate having inclined bearings to support the oscillating parts, and a locking-notch, all as hereinafter more fully described and claimed.

In the accompanying drawings, Figure 1 is a perspective view of my sash-fastener mounted on the sash-rails and in locked position. Fig. 2 is aside elevation of the fastener in unlocked position, and Fig. 3 is a similar view showing the fasteningarm engaged with the holdinghook and in position to draw upward to force the sashes into place. Fig. 4 is a vertical central section through the fastener, with the parts shown in locked position. Fig. 5 is a front view of the base-plate, with dotted lines indicating the several positions of the operating-handle as shown in Figs. 2, 3, and 4. Figs. 6 and 7 are rear views of the fastener with the holding-hook removed, respectively showing the parts in locked and unlocked positions. Fig. 8 is a plan of the base-plate Viewed in aline at a right angle to the axis of the journal-bearings. Fig. 9 is a plan of the holding-hook and plate. Fig. 10 is a front elevation of the operating-handle, and Fig. 11 is a view of the fasteningarm and its shaft.

Referring to the drawings, A designates the base-plate of the fastener, which is mounted upon the meeting-rail B of the lower sash and firmly secured at each end by suitable screws inserted through the vertical perforations c. The base-plate is hollowed out on its lower side to reduce its weight, and is formedwith a pair of parallel brackets or ears, 0 0, ar ranged, respectively, coincident with the front and rear edges of the casting, each sloping backward or rearward from the base, and thus leaning or inclining toward the upper sash,as shown. Each bracket is perforated through at right angles to its face, to form a journalbearing, f, transverse to the base, and both bearings are in the same axial line and oblique to the plane of the sashes. The rear bracket is formed with a locking notch or recess, (2, in its rear face, vertically over the journal-bearing, and preferably extending from the perforation to the upper edge of the bracket. A projecting shoulder or stop, 9, is formed on the back of the rear bracket, 0, coincident with one side of the locking-notch d, and preferably extending the entire height of the bracket, to facilitate molding the casting; but the upper part only of the stop adjacent to the notch is required in the action of the parts.

I in the drawings designates the fasteningarm of the lock mechanism, or the part which fastens the sashes together. The fasteningarm is formed on the end of a cylindrical shaft or trunnion, k, which is fitted in the journalbearings f of the base-plate A, with the fastening-arm on the rear side of the base. The fastening-arm is nearly as wide as the lockingnotch (Z, and has a locking-projection, a, on its front side fitting the notch. The face of the projection is adapted to bear against and slide in contact with the rear face of the bracket as the arm turns from a position vertically downward through a semicircle to the opposite position vertically upward and coincident with the locking-notch. The shaft of the arm has a radial perforation, 7b, in which a pin or stud, t, is driven or otherwise secured, with one end projecting beyond the circumference of the shaft, as shown.

A cylindrical sleeve or perforated hub, in, is received or journaled upon the shaft of the ICO fastening-arm between the brackets e c, and is formed with an operating-handle, 1', which projects radially and .frontward, terminating in a knob, s, projecting clear of the front of the base. The sleeve is fitted to'turn freely on the shaft and between the brackets, and has a cam-slot, a, on one side, extending spirally around the hub analogously to the thread of a nut. The slot opens entirely through to the inside of the sleeve and receives the radial pin it on the shaft. Thespiral is preferably extended around the sleeve in the right-hand direction-that is, in the same direction as the threads of ordinary right-hand screws-and the shaft, pin, and slot are so placed that when the fastening'arm is vertically down and the operating-handle is at the back or left-hand extremity of its throw the pin will be at the leading end of the slot as the sleeve is turned over to theright. With this motion of the sleeve, therefore, the spiral cam-surface presses on the pin in the direction to draw the shaft axially forward; but as the fastening-arm bears against the face of the rear bracket, e, the rotation of the operatinghandle will cause the piu,'shaft, and arm to revolve until the arm is arrested by the stopshoulder y, coincident with the locking-notch, when with the further movement of the bandle the spiral surface on the rear side of the slot will slide along the pin and draw the shaft axially forward, thus entering the projection n into the locking notch. In this Position the fastening-arm cannot be turned or moved ex cept by the backward or reverse motion of the handle.

Mounted upon the meeting-rail of the upper sash opposite to the front base-plate is a holdinghook, L, formed integral with a base, y, which is held in place by common screws. The hook is bent over forward aud-downward in suitable form to interlock or.hook over the fastening-arm I when the arm is uppermost. The front face of the hook is set just back of the plane of the joint between the sashes, and the fastening-arm is set to also just clear the joint-line when down. arranged the sash-rails will pass freely; but as the operating-handle r is turned from the position shown in Figs. 2 and 7 over to the right the fasteuingarm will be swung on an incline into the plane of the upper sash and under the holding-hook L, as shown in Fig. 3, and thus drawn axially until the arm is locked in the notch 61, as shown in Figs. 1 and 4, thus clamping and securing the sashes together, and seating them tightly against the horizontal parts of the window-jamb, effectually pre- Venting rattling and excluding the wind or rain. The reverse motionof the handle un- "locks the arm and swings it down out of the plane of the uppersash. The weight of the operating-handle holds it down at each extremity of its-throw, and thus the parts. can neither be fastened nor unfastened by jars or accidental causes. The fastening-arm may be made to lock in either direction, according as With the parts thus.

the cam slot is made right or left hand.ed; but the right-handed action shownus preferred. The slot is preferably made w th a varylng pitch,.bcing almost circumferential to the shaft at the end where the pin tremains when locked, in order to prevent the arm from backing out of the notch 01. v

It is not necessary to arrange the fasteningarm so that it turns through an even half-revolution, as shown; but any fraet1on of a revolution that will conveniently sw1ng the arnr Clear of the holding-hook or keeperlssuffi cicnt.

The angle of the incline of the 3X18 of the fastening-arm may be varied considerably, it required, and the positions of the pin 15 and.

cam-slot may bereversed that is, with the pin in the sleeve and the slot in the shaft; but it is most convenient to arrange themas shown. It is also preferable to place the pin in line with the fastening-arm, so that there will be very little cramping action on the shaft; but the pin may be placed anywhere around the circumference of the shaft, 1f reuired. q In situations where it is not required to lock the parts securely the handle may be rlgldly fixed on the shaft of the fasteningarm, and the arm then merelyswung into engagement with the holding-hook, but not locked. The base and the arm may be made so that the locklngnotch and projection on are differently placed, and the fastening-arm may be formed on the zoo sleeve andthe operatinghandle placed on the shaft, the sleeve being made with sufficient end-play to draw axially, and the shaft belng held by thrust-collars, so that 1t cannot move endwise, which converse arrangement of the parts will fulfill the same functions as the preferrcd form; but the construction shown and described is very simple and impossible to get out of order, acts and holds positively and without the use of springs or frlction devlces, requires no skillful fitting or riveting together, as the pin it, when inserted, secures all the parts in place, and the lock may therefore be cheaply constructed, perfectly and eas ly 0pcrated, and is of neat and compact design.
