SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 769,374, dated Sep be 6, 1904.

i Application filed March 10, 1904. Serial No. 197,508. (No model'.)

. To all whom it may concern.-

Be it known that I, SrARKs M. BERRY, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented anew and useful Sash-Fastener, of which the following is a specification.

The object of this invention is to provide a sash-fastener which when in proper place on the sash and locked or unlocked and with the sash either raised or lowered will be almost entirely concealed from view, the general The accompanying drawings illustrate the invention, and referring thereto Figure 1 is a perspective of a portion of a window with the invention applied to the sash. Fig. 2 is a plan view of the invention, showing part of the sash. Fig. 3 is a horizontal section taken through the center of the sleeve, showing part of the sash. Fig. 4 is a'plan view of the lockframe with the top plate broken away. Fig. 5 is a rear elevation of the device. Fig. 6 is a perspective of'the'face-plate. Fig. 7 is aperspective of the locking-bolt. Fig. 8 is afront elevation of the bolt-frame.

Referring to the drawings, 1 designates the upper sash, and 2 designates the lower sash. To the uppersash 1 is screwed aface-plate 3, having an orifice 4. The plate is beveled, as at 5, forming an inclined bearing-face which gradually merges with the wall of the orifice 4. A bolt-frame, which consists of a top plate '6 and a front plate 7 at right angles thereto,

is screwed to the lower sash 2, and the top plate 6 is provided with an elongated slot 8, which merges with an offset slot 9, affording stop- walls 10 and 11, and a guard 12. The front plate 7 has an orifice 13, similar in outline to the orifice 4. A sleeve 14 projects inwardly from the face-plate 7 underneath the top plate 6, With its axis substantially parallel withthe top plate. The sleeve in its upper wall isslotted longitudinally at 15 and is provided with asegmental slot 16. Arevoluble and slidable locking-bolt 17 lies within the sleeve 14 and has a neck 18,.whichcarries a head 19. A finger-piece 20 projects radially from the bolt 17 and lies within the slot 8, and by-rocking the finger-piece through the slot 8 the bolt 17 may be turned.

The finger-piece 20 is preferably formed integral with the bolt, which necessitates making the slots 9 and 15 open at the rear and substantially in the same plane with the axis of the bolt, so that the finger-piece can pass into the slot 8 as the bolt is inserted into the sleeve 14. The stop 12 stands across the portion of the slot 9 in line with the end of slot 8,.and will thereby.engagewith the fingerpiece 20 and prevent its passage out of the slot 9 until it has been rocked beyond the stop.

The head 19 of the bolt isrectilinear in outline and is adapted to enter the plate 3 through the slot 4, and by turning the bolt the head sweeps around and grips theback of the plat-e 3. The inner face of the head 19 is beveled, as shown, so that as the finger piece 20 is turned toward the stop-wall 10 the inclined face of the head 19 rides upon the beveled face 5,

and the resulting action is to draw the upper and lower sash toward each other and squeeze the plates 3 and 7 tightly together. By constructing the-bolt and frame in this manner it is necessary to recess the sash for the boltframe and the face-plate and also for the sleeve and the head of the bolt, so that the front plate and the face-plate will each be flush with its sash, and thus permit of the two sash making a close joint when the window is closed.

The sash may be unlocked by turning the finger-piece 20 against the stop-wall 11, which rocks the locking-bolt, so that the head 19 may readily pass through the orifice 4.in plate 3. The finger-piece 20 is then pulled into the slot 9 until it strikes the guard 12, which slides the locking-bolt along the sleeve 14 and withdraws the neck and head of the lockingbolt from the plate 3. i

It will be noted that the screws which fasten either member of the device to the sash pass transversely'into the sash, so that the holding power of the screws is very much greater than the holding power of screws as employed in securing the ordinary form of sash-fastener to the sash, as in the latter when sufficient force is applied to raise or lower the sash the screws may be forced lengthwise out of the wood, the wood tearing out along the screwthreads, while in the present device it is impossible to force a sash open, as the pressure sustained by the screw is a lateral pressure and the only way to force the attachment free from the sash would be by shearing the screws, which could not be accomplished without injuring the sash itself in consequence of the severe strain necessary to shear the screws.

When the device is unlocked and the fingerpiece 20 lies within the slot 9, the angular disposition of the finger-piece 20 causes it to abut against a shoulder 21, and this shoulder serves to prevent the accidental outward shifting of the locking-bolt when unlocked, making it necessary in order to lock the device to slightly raise the finger-piece 20, so that it clears the shoulder 21, before the locking-bolt may be slid outward. Sufiicient clearance is provided between the finger-piece 20 and a shoulder 22 to allow of the necessary slight upward raising of the finger-piece 20 to clear the shoulder 21.

It is obvious that when the device is applied to the sash the only thing projecting from the sash at any point is the small tip of the fingerpieee 20, and this is of such insignificant proportions that it does not mar the appearance of the sash. 7

It is obvious that it is impossible to force a window when locked by the present device without tearing the sash or breaking the glass, and this feature, together with the unobtrusiveness of the device when applied, is considered of particular importance and value.

What I claim is 1. A sash-lock comprising a slotted boltframe, a sleeve thereon below the top and having its axis substantially parallel therewith, a bolt revoluble and slidable in the sleeve,

a finger-piece on the bolt extending through the slot in the frame, a plate having an orilice for receiving the bolt, and means on the bolt for engaging the plate.

2. A sash-lock comprising a slotted boltframe, a sleeve thereon below the top and having a longitudinal and segmental slot, a bolt revoluble and slidable in the sleeve, a finger-piece projecting from the bolt through the slotted sleeve and through the slot in the frame, a head on the bolt, and a plate having an opening for receiving the head of the bolt.

3. A sash-lock comprising a bolt-frame havinga top plate and a side plate, the top plate having an elongated slot, and having an oilset slot merging therewith, a guard at the mouth of the offset slot, a sleeve on the frame below the top plate, a bolt revoluble and slidable in the sleeve and a linger on the bolt projecting through the slot.

4. A sash-fastener comprising a bolt-frame having a top plate and a side plate, the top plate having an elongated slot and an oll'set slot merging therewith and the side plate having screw-holes, a slotted sleeve on the frame below the top plate, the slot in the sleeve and the offset slot in the top plate, each being open at the rear and the offset slot being provided with a stop at its mouth, a bolt rcvolu ble and slidable in the sleeve, a neck and head on the bolt, a linger-piece on the bolt projecting through the slot in the sleeve and through the slot in the top plate, and a faceplate having a slot for receiving the head of the bolt.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, at Los Angeles, in the county of Los Angeles and State of California, this tth day of March, 1904.

SPARKS M. BERRY.
