sAsH-FAsTENER.

SPECIFICATION forming part of Letters Patent No. 508,361, dated November 7, 1893.

Application' filed June 17l 1893.

To all whom it may concern.-

Be it known'that I, DAVID YOUNG, a citizen of the United States, and a resident of Anglesea, in the county of Cape May and State of New Jersey, have in vented certain new and useful Improvements in Sash-Locks or Fastenfollowing to 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.

This invention relates to sash-locks orfaswindows, and has for its object to provide a device of the character set forth which is strong and durable and will stand vibratory force and shocks or blows incident to the jarring and jolting of a moving car without becoming injured or impaired, and will thereby always insure a ready operation without the inconveniences and disadvantages usually attendant upon the fastenings of car-windows. With these and other objects in view, the

rangement of the several parts as will be more fully hereinafter described and claimed.

In the drawings: Figurel is a front elevation of a car-window frame and sash broken away at several points and showing the improved lock or fastener applied thereto. Fig. 2 is a section on the line Fig. 4:,showing the lock or fastener operated to release the bolt for the purpose of raising the sash. Fig. 3 is a view similar to Fig. 2 with the bolt in locked position. Fig. 4 is a transversevertical section on the line y-y Fig. 1. Fig. 5 is a detail perspective view of parts of the lock or fastener disassembled.

Similar numerals of reference are employed to indicate corresponding parts in the several figures of the drawings.

Referring to the drawings, the numeral 1 designates the sash frame having the customary sash-grooves in opposite sides thereof in one of which is formed a series of recesses 2 and thereover is fixed a metallic wear strip 3 having openings -i therein aligning with the said recesses 2. The lower part of the right of the sash is provided with a mortise 5 having a front opening 6 and at the edge is supplied with a bolt opening 7. Over the said bolt SerialNo. 477.997- (No model.)

opening is mounted an escutcheon plate 8 having an opening therein aligning with the said bolt opening 7 and acting tohold the bolt in proper position and take up wear.

ToV the outer lower side of the sash is secured a tubular sleeve 9 having an inner integral collar l0 that bears against the sash and in advance of the said collar the said sleeve is formed witha pair of oppositely disposed lugs 11. Within the said sleeve 9 is located a pushbar 12 having an outer shouldered collarI 13 .which is movably fitted in the said sleeve and formed with an outer a'nged head 14 provided with a milled edge, the said flanged head limiting the inward movement of the collar 13 and the push-bar l2. The push-bar 12 is surrounded by a coiled spring 15 which has its inner end bearing against thelugs l1 and its outer end against the shouldered collar 13, the normal tendency of the said spring being to force the said collar outwardly as will be readily understood. Pivotally mounted between the lugs 11, is a bell-crank lever 16, having a cam-arm 17 with a stud or post 18, rising therefrom, and a cam-lug 19 in rear of the said stud or post. VThe other arm, 20, of the said bellcrank lever is formed of about the same thickness as the greater part of the said cam-arm, and is supplied with an opening 21 near the end thereof. The elbow of the said lever has an opening 22 therethrough throu gh which eX- tends a rigidly mounted pin 23, whose opposite ends are secured in the said lugs 11 and on which the bell-crank lever freely turns. The inner end of the push-bar l2 is iiattened and formed to somewhat resemble a cam to engage the curved edge of the cam-lug 19 which is adjacent thereto for the purpose of properly operating the bell-crank lever. The said inner end of the push-bar is formed with an opening 24, through which the stud or pin 18 passes to provide a pivotal connection of the two parts.

To the arm 20 of the bell-crank lever is pivotally connected the inner bifurcated end 25 of a slide-bolt 26, the said slide bolt being normally disposed in a plane at a right angle to the plane of the push-bar l2, and has its outer end beveled as at 27 for evident and wellknown purposes.

in the opening 7 of the sash and is adapted to IOC This slide-bolt is mounted have bearing in the escutcheon 8, andengage the recesses 2 for holding the sash in its adjusted position. When the collar 13 and head 14 thereof are free to be iniiuenced by the spring 15 the bolt 26 occupies a normal locked position, as the said spring exerting its force on the push-bar 12 through the collar 13draws the cam-arm l7 of the bell-crank lever outwardly and through the arm 2O of said lever toward the sash frameand consequently moves the slide-bolt in a similar direction. By the intervention of the said bell-crank lever it will be observed that the spring 15 is caused to act reversely on the slide-bolt in view of the operation of springs of a similar character usually employed with sash-locks or fasteners for car-windows. On pressing the push-bar 12 inwardly as shown in Fig. 2 the adjacent bearing edge of the cam-lug 19 is engaged firmly by the inner end of the said push-bar and the beILcrank lever is thereby operated on its pivot to move the arm 20 backwardly from the sash-frame and retract the slide-bolt 26 to permit the sash to be raised. The provision of the cam-lug relieves the stud or post 18 of a part of the wear and tension which would otherwise be brought to solely bear thereon. It will also be seen that in raising the sash the sleeve 9 may be eiectually used as a grip in addition to the ordinary linger `grip which will be provided as shown in Fig. l, and the movement of the operator to release the slide-bolt, being an inward push, instead of an outward pull, the sash may the more readily and quickly be raised.

While the device is shown applied to a car- Window, it will be understood that it can be as readily employed in connection with any other form of sash and in all forms of application thereof, such changes that lie within the scope of the invention together with a Variation in the proportions might be made and substituted for those shown and described without in the least departing from the nature or spirit of the invention.`

Having thus described the invention, what is claimed as new islIn a sash lock or fastener, the combination of a spring actuated push bar, a slide bolt disposed at a right angle thereto, and a bell crank lever connected to the inner end of said slide bolt and push bar, and having a projecting cam lug with which the inner end of said bar is adapted to engage said cam lug, being located on the outer side of the bell crank lever having its bearing edge corresponding in contour to the inner end of the push bar, substantially as described.

In testimony whereof Il have signed this specification iu the presence of two subscribing witnesses.
