COMBINED SASH LOCK AND OPENER.

Specication of Letters Patent.

Patented Mar. 21, 1911.

.Application filed April 23, 1908. Serial No. 428,754.

To all whom it may concern:

Be it known that I, CLINTON D. TABoR, a citizen of the United States, residing at New Dorp, in the county of Richmond and State of New York, have invented a new and useful Improvement in Combined Sash Locks and Openers, of which the following is a specification.

This invention relates to opening and locking means which are applicable more particularly to centrally pivoted sashes which are capable of both a horizontally swinging movement and also a vertically sliding movement in the frame.

The object of this invention is to provide simple and eflicient means whereby these functions can he easily and reliably performed.

In the accompanying drawings consisting of 2 sheets: Figure 1 represents an inside elevation of a sash and frame provided with my improvements. Fig. 2 is a vertical section thereof in line 2 2, Fig. 1. Fig. 3 is a horizontal section in line 3--3, Fig. 1. Fig. 4 is a fragmentary vertical section on an enlarged scale taken in line 4-4, Fig. l, and showingthe position of the sash ,opening and locking device when the sash is closed. Figs. 5, 6 and are views similar to Fig. 4 showing diiferent positions of the sash opening and locking device. 9 and 10 are perspective views showing the parts of the sash opening and locking de-` vice detached. Fig. 11 is a fragmentary vert-ical section in line 11-11, Fig. 1.

Similar letters of reference indicate corresponding parts throughout the several side jambs and a horizontal head jamb 5 connecting the upper ends of the side jambs.

6 represents the sash which is capable of turning in a horizontal plane and also of sliding vertically in vthe frame. For this purpose the sash is pivoted centrally by its upper and lower rails 7, 8 by any suitable means. In the closed position of the sash the same is in line with the frame and engages by means of an` outwardly facing shoulder 9 on its outwardly closing stile 12 with an inwardly facing shoulder or stop Figs. 8, y

its inwardly closing stile 12a with an outwardly facing shoulder or stop 13 on the adjacent side jamb 3 of the frame while its lower rail 8 rests upon a stool 14 secured to the upper side of the main sill. rlhe space between the top rail and the head jamb is closed by a follower or strip 15 which engages with its under side against the upper edge of the top rail while its upper edge is arranged in a pocket or a recess 16 formed between inner and outer cleats, strips or bars 17, 17 secured to the underside of the head j amb. While in this closed posit-ion a weather tight joint is produced between the bot-tom rail and stool by means of a longitudinal rib 18 formed on the upper side of the stool and engaging with a longitudinal groove 19 on the underside of the bottom rail and the joint between the top rail and the follower is also rendered weather tight by means of a longitudinal rib 21 formed on the underside of the follower and engaging with a longitudinal groove in the upper side of the top rail, as shown in Fig. 11.

The pivotal connection between the lower rail of the sash and the stool comprises a sill plate 22 secured centrally to the upper side of the stool and provided with an upwardly proj eeting pivot pin 28 which enters a socket formed partly in a lower sash plate 24 which is secured centrally to the underside of the lower rail and partly in said rail above the plate 22.

The pivotal connection between the upper or top rail of the sash, the follower' and the head jamb consist-s of a vertical pin 25 secured at it-s upper end to the head j amb and arranged with its lower part in a central opening` 26 in the follower and a socket 27 in the top rail and also through coinciding openings 28, 29 formed in pivot plates 30, 31 which are secured respectively to the upper side of the top rail and the underside of the follower, as shown in Fig. 2.

The follower is yieldingly held in its depressed posit-ion in engagement with the top rail of the sash by a spring 36 surrounding the upper pivot pin 25 and bearing at its upper end against the base of said pin while its lower end bears against the upperside of the follower plate 31.

Upon turning the sash from its closed and lowered position the wedge action of the ribs and grooves between the lower end of the sash and the frame causes the sash to be lifted until the lower rail of the sash reaches the top of the lower ribs after which it rests on top of these ribs and remains in this vertical position upon swinging the sash horizontally into a more or less open position. While thusl raising and turning thev sash the follower rises with it and is raised an additional extent by the wedge action of the cooperating upper ribs and grooves between these parts. Upon swinging the sash back into its closed position into line with the frame the sash drops with its lower groove over the rib on the stool and the follower descends with its rib into engagement with the groove of the head rail.

My improved means for opening the sash and locking the same in its closed position are constructed as follows :H37 represents an upright locking plate secured to the face of the jamb 2 by screws or otherwise and provided with a forwardly projecting locking lug 38. The latter is provided at its front end with an upwardly projecting lip 39 forming an outwardly facing shoulder -LLO while its inner end is curved or rounded downwardly and outwardly to a downwardly facing shoulder Ll1 on the underside of this lug.

42 represents a pivot plate secured to the edge of the sash stile l2 and provided with an inwardly projecting pivot lug 43 which carries a pivot pin or stud 44 projecting laterally toward the adjacent side jamb 2 of the frame. Upon this stud is pivoted the upper end of a vertically swinging handle or hand lever l5 which has its lower end constructed in the form of a hook-shaped finger piece for convenience in taking hold of the same with a finger. Below its pivot this handle is provided with an upwardly facing shoulder #il which is adapted to engage with the downwardly facing shoulder 41 of the locking lug 3S on the frame. Projecting inwardly and downwardly from the handle adjacent to its pivot is a locking dog 4G which is adapted to engage with the inwardly facing shoulder at its front end with the outwardly facing shoulder on the upper side of the locking lug 40. Above its pivot the handle is provided with a heel or tail piece 4S which is arranged at an angle to the handle and adapted to engage with the adjacent part of the locking lug plate or other stationary part on the frame.

lVhile the sash is swung into its closed and lowered position land the opening' and locking device is in its operative position the handle is arranged vertically and engages with its upwardly facing shoulder against the downwardly facing shoulder on the underside of the locking lug, the locking dog engages its end with the rearwardly facing shoulder of the locking lug and the heel is separated from the frame. as shown in Fig. fl. In this position of the parts it is impossible to raise the sash owing to the engagement of the handle shoulder with the underside of the locking lug and it is also impossible to turn the sash horizontally owing to the engagement of the dog with the outwardly facing' shoulder of the locking lug. It is therefore impossible to open the sash from the outside of the building and it is also impossible to open the sash from the inside of the room except by manipulating the opening and locking device. 1When it is desired to open the sash, the hand lever first swung inwardly and upwardly until its locking dog clears the outwardly facing shoulder of the locking lug and the heel thereof bears against the adjacent part of the sash or locking plate, as shown in Fig. 5, and upon then continuing this upward and inward movement of the handl-e and sash is simultaneously raised and its swinging side is moved inwardly. during which movement the upwardly facing shoulder, of the handle swings inwardly and upwardly around the curved face of the locking lug and clears the same so that the sash can be swung wide open. As the tail of the hand lever engages the frame during this inw-ard and upward movement of the handle a lifting effect is produced on the sash which relieves the wedge action of the cooperating inclined surfaces of the rib and groove on the stool and the bottom rail, thereby causing these parts to wear less and the sash to be opened more readily and easily.

lVhen the sash has been fully opened and the handle is released the parts of the opening and locking device assume the relative position, shown in Fig. 6. Upon subsequently turning the sash in the direction for closing the same the'parts of the locking device remain in this position until the sash has nearly completed its closing movement at which time the locking dog engages with its underside against the top of the locking lip, as shown in Fig. 7. As the sash completes its horizontal closing movement and drops into its lowered position the locking dog is lifted by the lip together with the handle and when the dog has cleared this lip it drops into engagement with the shoulder on the outer side of this lip and` the handle swings with its lower shoulder around the curved end of the looking lug and into engagement with the shoulder on the underside thereof, as shown in Fig. 4, whereby the sash is again locked against upward and inward movement. This operation of locking the sash is wholly automatic and effected solely by swinging the sash into .its closed position in line with the frame, thereby dispensing with separate closing and locking operations for this purpose. By thus combining the sash opening and locking device in one structure the fittings which ordinarily would be required for this purpose on a window of this character are materially reduced and the appearance of the same is much improved.

I claim as my invention:
