Specification of Letters Patent.

Application led January Z6, 1906. Serial No. 297,950.

To all whowb it maf/ zj concern:

Be it known that I, JAMES B. VINCENT, a citizen of the United States, residing at Flatbush, Long Island, in the county of Kings and State of New York, have invented certain new and useful Improvements in Sash- Locks, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to locks for windows; and the object thereof is to provide an improved device of this class which is simple in construction and operation and which is invisible eXcept from the inner side of the window; and with this and other objects in view the invention consists in a device of the class specified constructed as hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which- Figure 1 is an inside view of the bottom portion of the upper sash and the top portion of the lower sash of a window and showing said parts provided with my improved sashlock; Fig. 2, a section on the line 2 2 of Fig. 1, and Fig. 3 a plan view of the construction as shown'in Fig. 2.

In the drawings forming part of this speciiication I have shown at a the bottom part of the upper sash of a: window and at l) the top part of the lower sash, and the bottom part 'of the upper sash is provided with a bottom rail a2 and the top part of the lower sash with a top rail b2, and in thepractice of my invention I form in the top part b2 of the bottom sash a longitudinal recess or chamber b3, which opens backwardly through said part of the upper sash at one end of said chamber, as shown at b4, and the back surface of the part b2 of the bottom sash is also provided in the form of construction shown with a countersunk plate b5, having an opening similar to that of b4.

The bottom rail a2 of the top sash c is provided in the front surface thereof with a chamber or recess a3, 'adapted to register with the opening b4, and secured to the front surface of the part a2 is a guard-plate a4, having an opening which corresponds with the chamber or recess a3.

Pivoted in the chamber or recess b3 in the top rail b2 of the bottom sash and ranging longitudinally of said chamber is a dog c, said dog being pivoted nearer one end of said chamber than the other, as shown at c2, and the free end of said dog is provided with a backwardly-directed nose c3, 'which is adapted to enter the chamber c3 when the sashes are in their closed position, and formed in the head of the dog c is a recess c4, and pivoted to Vthe front surface or face of the top rail b2 of the bottom sash b is a catch d, adapted to enter the recess c4 and to hold the dog c out of engagement with the top sash when the sashes are not locked together. A guardplate e is also preferably secured to the top rail b2 of the bottom sash and provided with an opening which corresponds with the chamber b3 and to which the catch d is pivoted in the form of construction shown, and said plate is provided withstops e2 and c3, which are adapted to limit the movement of the catch cl, and in practice the dog c is pivoted to the inner side of the said plate c.

The operation of this device will be readily understood from the foregoing description, when taken in connection with the accompanying drawings and the following statement thereof. When the dog c is in the position shown in full lines in Fig. 2 the sashes are locked together, and when said dog is in the position indicated in dotted lines in Fig. 2 and shown in full lines in Fig. 3 the sashes are free to be moved or adjusted to any desired position. The dog c may be held in the unlocked position by the catch d, and when this is done there is no danger of breaking the dog or the nose thereof or of injuring the sashes by the vertical movement of said sashes when the dog is in the operative position. The dog c is swung into the operative the head end thereof and into the inoperative position, as shown in Fig. 3, by pressing on the heel thereof,

I-Iaving fully described my invention, what I claim as new, and desire to secure by Let-v ters Patent, is

l. A sash-lock comprising an oblong chamber formed in the front surface of the top rail of a bottom sash, a dog pivoted in said chamber and provided at one end with a nose adapted to pass backwardly through said rail and to entera recess formed in the front wall of the bottom rail of the top sash, and
