UNTTED A, STATES PATENT OFFICE.

HENRY U. PRINDLE, OF VOODLAND, CALIFORNIA, ASSIGNOR OF ONE-HALF TO JOHN IV. GUTI-IRIE, OF SACRAMENTO. CALIFORNIA.

SASH-LOCK.

SPECIFICATION forming part of Letters Patent No. 645,213, dated March 13, 1900.

Application filed March 29, 1899. Serial No. 711,041. (No model.)

State of California, have invented a new andv Improved Sash-Lock, of which the following is a specification.

This invention, which relates to improvements in .sash-locks, more particularly refers to that class of sash-holders inwhich the lock xo is mounted in the window-casing and provided with suitable clamping means for engaging the sash and holding it locked to any of its adjusted positions.

Primarily my invention seeks to provide a x5 lock device of this character of a very simple and economical nature, which can be easily fitted to the Window casing and sash, easily manipulated, and which will effectivelyserve for its intended purposes. zo This invention comprehends a novel construction of sash-lock having a combined guide and lock member movable with the sash and lock-clamp devices held to engage such member when under a normal condition z5 and to be moved to a position to allow for a free play of the said combined lock and guide member when they (the clamp devices) are manipulated by the unlocking key or tumbler.

In its subordinate features my invention embodies a peculiar combination of parts and novel details ot construction, as will be first described in detail and then be specifically pointed out in the appended claim, reference being had to the accompanying drawings, in

which Figure 1 is a face view of a portion of a window with my improved sash-lock device applied. Fig. 2 is a vertical section of a portion of the window sash and casing and my improved locking devices, the lock-clamps being shown to their normal (locked) posi-I tion in full lines'and to their unlocked position in dotted lines. Fig. 3 is a horizontal section of the parts shown in Fig. 2, taken on the line 3 3. Fig. 4 is a transverse section on the line 4 4, illustrating the key or tumbler devices more clearly. Fig. 5 isa detail View of the tumbler.

5o view of one of the sash-brackets or bearing members for the slide-rod. Fig. 7 is a detail Fig. 6 isa detaill View of the lock-casing and detachable coverplate therefor, and Fig. 8 is a detail View of one of the pivoted clamp-plates hereinafter particularly referred to.

.and bottom plates 2 3, provided with bosses 6o 2 3, having threaded sockets for the screws which secure the detachable cover-plate 4 in place, said topaud bottom plates also having vertical face portions 2b 2, which form the securing-anges which are apertured'for 65 the passage of the securing-screws 5 5. The casing is also formed With an integral front side portion (5, which merges with the loop or sheath 7, disposed over the front face of the lock-casing, butwhich is of a length less 7o than the height of the front open end -8 of the casing, whereby open ways 9 9 are formed at the upper and long ends of such front for a purpose presently explained. 'The front and back Walls of the casing have alining apertures 11 11a to receive the ends of the hub 122L of the tumbler 12, the construction of which is clearly shown in Figs. 2 and 5, by reference to which it will be seen the hub has a non-circ ular transverse aperture 13,adapted 8o to receive the flattened end 14CL of the operating-key shank,which has alinger-knob 14, preferably formed integrally therewith and having an annulargroove14b to receive the inner semicircular edge of the'divided Washer- 85 plate 15, which is securedto the casing and serves as a retainer to hold the key-shank in its proper position, as clearly shown in Figs.

l and 4.

In the practical application of my inven- 9o tion mortises are cut'in the runways of the sash, one near the upper end of the lower sash and thevother near the lower end of the upper sash, into which the lock-casings, with their integral members, are fitted, their securing-lianges 2b 2c being fitted in countersunk depressions to bring their faces flush with the slideface of the runways, and with each lock-casing mortise connects the key slot or bore 16 16, as clearly illustrated in Fig. 4, by roo reference to which and to Fig. 1 it Will be observed that nothing of my sash-lockdevices but the inger-knob and the retainer-Washer appear to view, The front back-walls of the lock-casing near their upper ends have coincident apertures 17, which form bearings for their laterally-projected pintles 18a ou the swinging clamp-plates 18, (in practice made of steel,) which have their front ends projecting through the open ways 9 9 and in line with the sheath or loop portion 7, While their inner ends rest against the opposite sides of the tumbler, aga-inst Which they are l always held pressed by the stout coil-spring 19, disposed about the slide-rod 2O and between the outer ends of such clamp-plates 1S, which ends are provided with apertures 2l, slightly elongated for a purpose presently described and through which the slide-rod 2O passes.

The slide-rod 20 is secured to and travels with the sash 22, a-nd to provide for a simple means of adjustment said rod has its opposite ends formed with right and left threads adapted to engage with the correspondinglyapertured bracket-plates 24, secured in countersunk seats to the upper and lower edges of the sash, the lower end of the rod 2O terminatiug on the slotted hub, whereby it may be readily turned by means of a screw-driver.

As will be seen by reference to Figs. 2 and 3, the rod 2O is held iush with the outer edge of the sash,vvhich is provided with a longitudinal groove to receive it, which groove, however, is of a Width sufficient to allow for a free sliding of the sash edge over the loop or sheath 7 of the lock-casing, which encircles the said rod 20.

From the foregoing, taken in connection With the drawings, it is thought the operation and advantages of this invention Will be readily understood. It will be seen by arranging the clamp mechanism as described and shown the normal action thereof will be to clamp the rod 20 and hold the sash from movement in either direction, and byturning the key to the right the tumbler will swing the clamp-sash so that the front ends will close toward each other sufficient to release their clamping action and bring their apertures in such relation to the sash 22 as to admit of its sliding freelytherein, the apertures of the said clamp members being slightly elongated forv this purpose, it being understood that when thus shifted to the right the tension of the spring will cause the inner ends of the clamps to bear tightly against the tumbler,and thereby maintain the said clamps in their unlocked position until such tumbler is again shifted to the left.

By arranging the spring on the rod 2O the same can be quickly fitted in place and at all times held in a position in which it cannot be 'readily broken or dislodged. Furthermore,

by constructing the casing in the manner shown and arranging the clamps as described the lock-can be manufactured at a very low cost and be of a strong and durable character. Again, by providing the casing with an integral loop or sheath member 7 the rod 2O will at all times be held to its proper alinement and the spring from frictional contact with any part of the sash, the sheath also forming a long guide-bearing for engaging the sash to overcome any sagging or rattling thereof.

While I have shown my improvements as more especially adapted as a sash -locking means, it is manifestly not confined to such use only, as it can be employed in various mechanical devices Where it is desired to hold a sliding member locked to any of its adjusted positions. v

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

In a sash-lock of the character described; the combination with the sash having a grooved edge and the vertically-disposed sliderod secured thereto; the lock-casing having an open front edge and an integrally-formed sheath or loop projected over said front edge, and adapted to engage the sash-groove and form a iiXedly-held guide for the sash and to hold the same from engagement with the clamp device; a pair of opposing clamp members pivotally mounted Within the casing-a tumbler means for adjusting the clamps to a IOO
