UNITED STATES PATENT OFFICE.

HIRAM WALTER HOLMES, OF OAKVILLE, CONNECTICUT.

SASH-FASTENER.

To all whom it may concern:

Be it known that I, HIRAM WALTER HOLMES, a citizen of the United States, residing at Oakville, in the county of Litchfield and State of Connecticut, have invented certain new and useful Improvements in Sash-Fasteners, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain new and useful improvements in sash locks and has for its object to provide a device of this character which will permit of the adjustment of the sashes for purposes of ventilation, and is adapted to absolutely lock said sashes against movement to prevent the entrance of intruders into the apartments.

Another object is to provide a lock of simple construction which is adapted to be mounted upon the top of the lower sash, adjacent to the window frame, said lock having a plurality of slidable bolts adapted to engage in sockets in the upper window sash and in the frame.

A further object resides in the rovision of suitable means for holding saic locking bolts in their locked or unlocked positions whereby their actuation will be effectually prevented by the attempted relative movement of the sashes.

With these and other objects in view, the invention consists of the novel features of construction and the combination and arrangement of parts hereinafter fully described and claimed, and illustrated in the accompanying drawings, in which- Figure l is a perspective view of a portionof the window sashes and frame, showing my improved lock arranged in operative position; Fig. 2 is an enlarged top plan view, the top of the lock casing being removed; Fig. 3 is a section taken on the line 33 of Fig. 2; Fig. 4 is a detail perspective view of the bolt actuating element; Fig. 5 is a detail perspective view of one of the sliding bolts; Fig. 6 is a similar view of the holding spring; Fig. 7 is a detail view of the key; and Fig. 8 is a similar view of one of the socket casings. 7

Referring more particularly to the drawings A and B indicate the lower and upper sashes, respectively, and C the window frame in which said sashes are mounted in the usual manner.

Upon the top of the lower sash, preferably Specification of Letters Patent.

Application filed January 20, 1910.

Patented Sept. 13, 1910.

Serial No. 539,087.

at the left hand side thereof, my improved lock is mounted. This lock comprises the casing 5 which is provided with a removable top or cover plate 6 adapted to be seated upon the upper edges of the body of the casing and secured thereto by means of suitable screws 7 which are disposed through the cover plate and through the bottom of the casing, said screws entering the sash rail. The lock is further secured to the sash by means of the downwardly extending ears 8 which are struck outwardly from the bottom of the casing and disposed upon the side of the sash rail, said ears receiving suitable fastening screws.

Arranged within the lock casing for sliding movement are the locking bolts 9 and 10. These bolts are disposed at right angles to each other, and the longer locking bolt 9 is adapted for longitudinal movement and is engaged in the window frame in a manner to be hereinafter set forth. The other of the locking bolts 10 has transverse sliding movement and is adapted to engage with the side of the upper sash to lock the same against movement. It will be observed that the outer end of the lock casing is semi-circularly formed between the longitudinal edges thereof, as shown at 11. Between this semicircular portion and one side of the casing the locking bolt 9 is adapted to move. It is further guided in its sliding movement by means of the stud 12 secured in the bottom of the lock casing and extending through the cover plate 6 thereof. Similar guiding studs 13 are also formed upon each side of the transversely movable bolt 10 and have their upper ends disposed through suitable openings in the cover plate. An opening of suitable diameter is, of course, provided in the side of the lock casing through which the bolt 10 moves. Normally the locking bolts are disposed as shown in Fig. 2 ot the drawii'igs, wherein it will be noted that their inner ends are flush with the side and end of the lock casing when in retracted position.

An actuating element 14 is pivotally mounted for oscillatory movement within the casing, and comprises a substantially triangular-shaped body 15 through which the pivot pin 16 is disposed. Diverging arms 17 are integrally formed with this body and the outer ends of said arms are formed with longitudinal slots 18. Each of the bolts is formed with a flattened under face on its inner end, as shown at 9 and 10, respectively, and depending from these flattened faces are the pins 19. These pins are disposed in the slots 18 in the outer ends of the diverging arms 17, said arms moving on said pins in the actuation of the locking bolt. The point of the triangular body portion 14: is reduced, as shown at l-fl, and is adapted to be engaged by resilient blade 20. One end of this blade is secured upon a stud 21, and adjacent to said end it is disposed against the side of the lock casing. The major portion of the spring blade, however, is diagonally extended, as clearly shown in Fig. 2, and has its free end disposed in one corner of the casing and engaged with the inner end of the locking bolt 9. Intermediate of its ends the blade 20 is formed with a plurality of corrugations 22. The pointed end let of the actuating member is adapted to be engaged in one of these corrugations and yieldingly held against unintentional movement by the spring blade 20. WVhen the actuating member is moved by the insertion of a suitable key into the lock, the point thereof will move over the central corrugation and bend or flex the blade, and when the bolts have been moved outwardly in the casing to their locking positions, the point of the actuating member will be disposed in the other of the corrugations and securely held in such position. The inner end of the bolt 9 is preferably beveled, as shown at 23, for engagement with the end of the blade 20. The body of the actuating member let is provided adjacent to its outer end with the socket or recess 24 which is adapted to receive the end 26 of a key 25. This socket is disposed immediately beneath an arcuate slot 27 in the cover plate 6 of the lock casing. An opening 28 is also provided in the plate 6 adjacent to the slot 27 and is adapted to receive the short projection 29 formed on the end of the key, the portion of the lock casing between the slot 27 and opening 28 being received between the projecting studs 26 and 29 formed on the end of the. key.

In the side rail of the window sash and in the face of the window frame, a plurality of openings or sockets 33 are formed. These sockets are adapted to be protected or reinforced by the tubular sheet metal casings 34 which are disposed therein and are each provided with an annular flange on its outer end and the laterally extending ears 35 which are formed with suitable openings to receive the fastening screws 36. In the operation of the device the locking bolts are adapted to be received in these tubular casings, which will prevent wear upon the sash and frame and overcome the vibration of the window sashes which would result from a loose engagement of the locking bolts in the sockets.

In the operation of my improved sash lock,

after the sashes have been properly adjusted in the frame to secure the desired amount of ventilation at the top and bottom of the window, the key 25 is inserted into the lock, the longer stud thereof ext-ending through the arcuate slot 27 and into the socket or recesses 24 in the actuating member 14: while the shorter stud 29 is disposed in the opening 28 in the cover plate. They key is then turned, and the actuating member oscillated upon its pivot against the tension of the holding spring blade 20. Upon this movement the arms 17 will be moved downward and outward in the lock casing, and slide the bolts therein outwardly into engagement in the sockets in the side rail of the upper window sash and the window frame. Owing to the slot and pin connection between these arms and the bolts, the arms will slide upon the pins during the oscillatory movement of the actuating member, while the locking bolts are moved in a constant direction. The locking bolts are held in their locking positions by means of the holding spring 20 in the manner previously set forth, and the retraction of said bolts is effectually prevented until the key' is again inserted into the lock to move the oscillatory actuating member.

From the foregoing it is believed that the operation and many advantages of my improved sash lockwill be readily apparent without necessitating a more extended description. But few parts are employed in the construction of the lock and they are thoroughly incased and protected whereby the proper operation of the device is insured. The locking bolts are simultaneously moved at right angles to each other, and the locking engagement of the bolts with the window frame and sash is very quickly attained by but a slight movement of the key, thus facilitating the easy and rapid looking or unlocking of the window sashes.

WVhile I have shown and described the preferable form of the various parts and the manner in which they are to be associated, it will be obvious that the same is susceptible of numerous modifications without materially departing from the essential features or sacrificing any of the advantages of the invention.

Having thus described the invention what is claimed is:

A lock of the character described comprising a lock casing having a cover, sliding bolts mounted in said casing having angular relative movement, an oscillatory actuating element pivotally mounted in said casing comprising a body and diverging arms integrally formed therewith, said arms having movable connection with the inner ends of said locking bolts, the body of said. actuating element having a key receiving socket therein, a corrugated spring blade arranged within the casing engaged with said element and adapted to yieldingly hold the bolts against actuation, said cover plate having an arcuate slot above the socket in said actuating member and an opening adjacent to said slot, a key having lugs formed upon one end adapted to be received in said slot and opening, one of said lugs being disposed in the socket in the actuating member and adapted to move the same to slide the 10 bolts when the key is turned.

In testimony whereof I hereunto afiix my signature in the presence of two Witnesses.
