souri, have invented a new and useful Sash-Lock, ofV

which the following is a specification.

This invention relatesl'to a sash lock adapted for use' in `connection with windows, with or. without counter-balance weights for the sashes, wherebythesashes `can be locked either closed, or opened partially 4for the purpose of ventilation, without danger of their'gbeing -opened from the outside by unauthorised persons.

The invention has for one of its objects to provide a sash lock which is of simple and inexpensive constmction, easy to apply to ordinary windows, and reliable for holding a sash in any desired position.

A further object of the invention is the provision of a device .of this character, which comprises two parts, and, which serves as a grip or hand-hold for assisting in raising or lowering the sash.v A

With these objects in view, and others, as will appear as the nature oithe invention is better understood, theA invention comprises the various novel features of construction and arrangement o f parts, which will be more fully described hereinafter, and set forth with .particularity in the claims appended hereto.

.- ln the accompanying drawing, which illustrates cerof'fthe embodiments of the invention, Figure lis a fragmentary perspective view of a Window showing in' its unlocked positionby dotted lines. Fig. 3 is av side elevation, partly broken away, of a modified form of sash lock. Fig. 4 is a perspective view of a'mpdified form of gripping member.

Corresponding parts in the several figures are indicated throughout by similarcharacters of reference.

Referring tothe drawing, 1 designates the lower sash and 2 the frame of a window to whichy the ,locking device is applied. The locking device comprises a straight,-

smooth-rod 3, suitably fastened at its ends, and a lock- Aing member 4. The rod 3 may be attached to thrn window frame 2 and the locking member 4 to the sash, as

extending eye 5 for securing to the-sill of the window frame by means of a screw 6, or equivalent means. The upper end of the rod 3 is held in a bracket 7 which comprises a plate presented to the stile of the window frame and secured thereto by screws 8. vOne `end of the plate is turned laterally in a. horizontalplane toform a lug 9 having a central aperture 10 in which the upper end of the rod 3 is held. The rod 3 lmay thus be of any length and the bracket 7 can be arranged at any desired`point, so as to accommodate the sash lock to sashes Specification of Letters Patent. gippnmion nea october11,`19o6. serial sessanta.

venting children from opening thewindows far enough v to fall out. Another manner of securing the upper end of the rod 3 is shown in Fig. 3, wherein the extremity of the rod is formed into an eye 11 for receiving a screw, or equivalent `means, 12', whereby the said eye is securely fastened tothe stile of the window frame. l

The locking member 4 comprises, preferably, though not necessarily, a single piecefstructureV having abase 13 and two forwardly projecting portions 14 forming gripping jaws. ',lhe base 13 is presented to the inner face or front 'of the side rail of the window and secured thereto by screws 15 extending through apertures in lthe base 13 and screwing intothe said side-rail. The jaws or members 140i the locking device 4 are diverged from the base 13. and are normally under a tension that tends to spread them apart. Each jaw 14 is provided with an aperture 16 through which the rod 3 extends. The edges of the aperture 16 at the point 17 bite the v rod 3 and prevent relative movement between ,the said rod 'and the locking` device 4. The strip of metal from soA which the locking device 4 is made is of suitable spring.

material and the jaws14 are under considerable tension which tends to mhve them farther apart so that they will grip the rod 3. \The ends of the jaws opposite from the base 13 are bent inwardly toward each other at 18, andV these inwardly bentportions 'are themselves bent forwardly and outwardly inthe general direction of the jaws and form nger pieces or holds whereby the jaws can be gripped between the thumb and first ringer and compressed toward each other, so as to release the biting edges 17 of the jaws fromthe rod 3 when it is desired to move the sash. In Fig. 2, the full line posi.

tion of the jaws or members 14 represents the device 4 locked with respect tothe rod 3, while the dotted line position represents the device unlocked. It will be noted that in the dotted line position, the linger-holds 19 are in contact and thus they serve as stops for preventing the jaws from being compressed to such an extent as to bite on the rod 3 and thus prevent the sash from moving. When it is desired to adjust the position of the sash, the finger-holds 19 are taken between the thumb and. r'st finger of' the left hand and the jaws moved to the dotted line position shown in Fig. 2.

IWhile the device 4 is held-in this manner, the handhold 20 on the sash is'gripped -in the right hand and then the sash can be raised or lowered by liftingup with both hands or pushing down, as the case may be.

v While the jaws are held in the dot-ted line position, the

device 4 serves as a hand-ho1d sirnilarto the handhold 20 to assist in raising or lowering 'the sash.

In Fig. 3, the locking device is composed of two parts,

l 20 and 2l whichare oi substantially the same construction and arranged one within the other and secured by the same screws to the window sash. rlhis construction is employed where a strong gripping effect is desired, the relatively thin member 21 serving as an auxv iliary gripping device and to reinforce theiouter memof sheet spring metal, but the said device can be made from spring wire, if desired, as, for instance, as shown in Fig. 4. In this construction, a single piece of Wire of suitable length is employedand it is shaped at its middle to form the iat'base portion 22 that serves as an' eye for receiving screws 23 Whereliy the device is secured to the Windenr sash. From the flat base portion 22, the wire is bent vertically in opposite directions to "a suitable distance, and then forwardly to constitute the jaws 24.l Thejaws-24 are provided with eyes 25 through which the rod '3 extends, the said e'yes taking the place of the biting edges 17 oi the construction shown in Fig. 2. The outer-vends of the members 24 are turned toward each other and terminate in the finger-holds 26. It will thus be seen that the gripping or locking device can be constructed of Wire and obviously other forms than that shown may be employed.

I have described the principle oi operation of the in- Y vention, together with the apparatus which I now conv sider to be the best embodiment thereof, but I desire to have it understood that the apparatus shown is merely illustrative, and that various changes may be made, when desired, as are Within the scope of the invention.

What is claimed isz l. In a sash lock, the combination with a rod adapted to be attached to one of the parts having suitable securing means at one end and having a locking portion, and a guide for the upper or Afree end of said rod having a rod receiving portion slidahle longitudinally ot' the rod to permit the guiding bracket to be secured to a suitable support atditerent distances from the attaching end of the rod and serving :is an adjustable stop, of a locking device adapted to be secured to the other part of the window and having a clamping portion adapted to coperate with said rod .and adapted to coiperate with the adjustable guide to limit the opening movement of the sash to different heights..

2. ln a lock of th e character described, the combination with a locking rod. of a clamping device adapted to coperate therewith composed of a single piece of wire having an intermediate portion formedinto a loop adapted to reeeive' securing screws at opposite ends thereof, the ends oi' the wire being bent forwardly substantially at right angles to the plane of the securing loop and having convolntons forming clamping portionsadapted to coiiperate with the said rod.

ln a lock of the character described, the combination I with a rod adapted to be secured to one part, of a coperating clamping device adapted to be secured lo the other part comp sed it' a single piece ot' wire havingr an intermediate portion nent to form a loop adapted to receive securing screws at opposite ends, the wire being thence crossed Aand extended in opposite directions parallel to the plane of the loop, thence. bent forwardly at an angle to the plane of the loop `to form' oppositely arranged clamping,r arms; the latter hlaving eonvolutons formed therein to receive and coperate with the locking rod` the forward extensions of said arms serving,r as operating portions.

4. In a locking device of the character described. the combination with n rod and a lguide and stop slidubly connected to the rod` of a clamp composed ot' a single piece of resilient material embodying an intermediate attachingl portion adapted to engagea suitable support and to receive securing screws. fiyrwardly extendingr clampingarms nrranged substantially at `rightangles to the plane ot' the nt- 'taching portion and having.r portions adapted to l'rclionally engage the rod. and 'forwardly arranged inwardly oli'set angel-pieces on the ends el" the clamping arms adapted to coipcrute with one' another when the clamping' arms are proxnluted to insure releasing of both clamping arms relatively to the rod. I
