sAsH-FAsTENlEa SPECIFICATION forming part of Letters Patent N o. 664,162, dated December 18, 1900.

Application tiled October 4. 1900. Serial No. 32,037. (No model.)

To @ZZ whom/'it 1v1/ty concern:

Be it known that I, GEORGE E. LINT, a citizen of the United States, residing at York, in the county of York, State of Pennsylvania, have invented certain new and useful Improvements in Sash-Fasteners, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to sash-fasteners, and particularly to a structure by which one end of a bolt may be retracted within its casing by a spring tension or projected and held beyond the casing under an independent spring tension.

The invention has for one obj ect to improve the construction of parts shown in my prior patent, No. 651,464, of June 12,1900, so as to permit the lock-pin therein to perform all of the functions contemplated in that patent and also to adapt the saine to bey projected under an independent spring tension in order to automatically lock the window in any raised or lowered position when the pin cornes into alinement with a socket therefor. A

A further object of the invention is to provide a structure involving independent springs, one of which is capable of being placed under tension in order to project and hold the bolt in a direction opposite from that of the retracting-spring.

Other objects and advantages of the invention will hereinafter appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings,l Figure l is a perspectiveV of a window with the fastener applied thereto. Fig. 2 is a vertical section showing the parts in position to operate as a push-pin to release a locking-catch. Fig. 3 isa vertical section showing the projecting spring under.

beveled face A adapted to contact with the adjoining sash, and thus force the latch backward into its casing until the latch reachesa locking-recess in the adjoining sash. The beveled face of this latch diers from that shown in my prior patent by reason of the bevel upon the face A. The beveled face herein illustrated extends longitudinally of the latch and also laterally thereof, so that the point of contact with the latch begins at one corner a thereof and gradually increases until the entire lower edge is in contact. (See Fig. 6.) By this meansthe resistance to the movement of the sash is very slight and the latch easily depressed with the greatest or initial pressure in line with the guidepin A3, which extends backward from the face A'. This latch is circnlarin coniiguration, and thus rnuch more easilyapplied by simply boring a socket than the rectangular.

casing,'for which the socket must necessarily be mortised. The latch is provided with a iiange A2, fittingthe interior of the casing,

and the reciprocation of the guide-pin is lime,

ited and controlled by means of a slot A4,Y through which the `cross-pin of the casing These features of construction, however, are similar to those disclosed in my former patent. The latch is normally projected outward by means of a spring-latch O', located between the flange A2 and the rear wall of the casing O.

The push and lock bolt or pin E is located within a casing F, having at its inner end a collar F and at its outer end a face-plate F2, which may be secured to the casing by any desired means-for instance, lugs F3, passed through apertures F4 in the plate F2 andl bent down thereon. (See Fig.`3.) The pin E is provided at its inner end with a circular portion E', adapted to pass through the collar F',

andV with anintermediate reduced portion E2, around which the coiled projecting spring G is adapted to be located. The retractingspring H, which normally holds the pin within the casing, as shown in Figs. 2 and 5, bears at one end against the iiange E,3 upon the outer end of the pin and at its opposite'end against the collar or shoulder F', so that the tendency of this spring is to draw inward the end E of the pin. For the purpose of locking the retracting-spring under tension with IOO the bolt projected a locking-spring H is provided, which is secured at one end to the pin, and the opposite end H2 is bent at an angle and crosses the outer end or face of the pin E. This spring H is provided with a locktooth H3 and a slot Hl in the face H2,wh ich slot, in connection with a headed pin E, limits the movement of the spring, so that the tooth may be engaged or disengaged from the edge of the aperture in the face-plate F2, through which the pin passes. The general structure of the retracting-spring and its connections is similar to that disclosed in my prior patent, with the exception that the lockingspring is simplified in structure to obviate the necessity of the head or cap and permit the same to be formed of a single piece of metal readily secured in position to perform all of the necessary functions in the operation of the device.

The projecting spring G, heretofore described, bears at one end against a shoulder E5, formed between the parts E and E2 of the pin, and is connected at its opposite end with a tension-plate G', provided with a lockingtooth G2 and a finger-piece G3, by which said tooth may be depressed. The plate G is located wilhin a groove or recess formed in one face of the pin E, and the locking-tooth is adapted to engage a pivoted contact-plate G4, mounted upon the face-plate F2, which faceplate is cut away beneath the contactl in order to permit a free passage of the lockingtooth G2 when the pivoted contact-plate is thrown out of position. It will be seen4 that if the plate G/ be forced inward by means of the iinger-piece G3 the tooth G2 will engage the rear of the plate G4, placing the projecting spring G under tension and normally holding the end E of the bolt beyond the casing, whereby it will be automatically seated in any socket I into alinement with which it may come. The socket may be formed in any desired manner, but is preferably oval in configuration, as this shape insures a quick and accurate seating of the pin in the socket when the same comes into alinement, particularly if the sash is being rapidly moved.

From the foregoing description it will be seen that the operation of the retractingspring and locking-spring when the pin is used as a push-pin to release a latch is substantially the same as that disclosed in my prior patent and need not be here enlarged upon. The operation of the novel arrangement of projecting spring, however, is an improvement upon the former patent, by means of which the pin is adapted for use as an automatic locking-pin. When the parts are in the position shown by dotted lines in Fig. 3, it will be seen that if the plate G be pressed inward and the locking-tooth engaged behind the contact-plate G4 the spring G may bev placed under a tension greater than that of the spring H and thel end E of the bolt projected. The parts are then in the position shown by full lines in Fig. 3, whereby the projecting spring bears at one end against the shoulder E5 of the bolt and at the opposite end a iixed contact is secured by means of the connection of thc plate with the faceplate F2. When the end E of the pin travels in contact with the face of the sash, the spring will be compressed and the outer or pushing end thereof forced backward into the position shown by dotted lines, but as soon as the end E' cornes into alinement with the socket I the tension of the spring projects the end of the pin into the position shown by full lines and locks the sashes together. By a proper disposition of the sockets the upper sash may be lowered any desired distance for ventilation and locked in such position, or the cooperating sashes may be secured together in any other desired relation. In this connection it may be stated that if the contact-plate G4 be raised the tension of the projecting spring G is immediately released and the retracting-spring H at once act-s to withdraw the pin from the socket, and if it be desired to lock the pin in the socket the same may be accomplished by means of the locking-spring H', as described in myprior patent. The present invention therefore presents in a single device a push and lock pin or bolt capable of the several functions heretofore attained by independent devices, and thus renders the apparatus capable of use in a variety of different methods, dependent upon the wishes of the occupant of the premises.

It is obvious that changes may be made in the details of construction and configuration of the several parts without departing from the spirit of the invention as defined by the appended claims. As shown in Fig. 4, the retracting-spring may be omitted from the bolt and the same used as a sliding bolt or a spring-actuated bolt. The several parts of the projecting spring and the plate for placing the same under tension are capable of action independently of the retracting-spring, which has been herein disclosed as associated therewith.
