ILOCK MECHANISM FOR REVERSIBLE WINDOWS.

srnoi rron'rioiv forming part of Letters Patent No. 655,382, dated August 7, 1900. Apnlication filed March 26, 1900. Serial No. 10,195. (No magi.)

To all whom it may concern; V

Be it known that I, WILLIAM H. TALBOT, a citizen of the United States, residing at the city and county of San Francisco, State'of California, have invented certain new and useful Improvements in Lock Mechanism for Reversible W'indows; and I do'hereby declare the following to be a full, clear, and exact description of the same.

The present invention relates more especially to certain new and useful improvements in the means for lifting or actuating the lock rod or bar forming connection be tween the window-sash and the slide shoe or block of reversible windows; and the objects of the invention are to simplify the actuating means for the lock-rod, reduce the expense of manufacture,and at the same time enhance the appearance of the window.

In order to understand the invention, reference should be had to the accompanying sheet of drawings, wherein- Figure 1 is a general view disclosing the upper sash of the window partly broken away. Fig. 2 is a vertical sectional view taken on line a; a, Fig. 1; and Fig. 3 is a detail view of the lock-rod and its actuating mechanism.

In the drawings the letter A is used to indicate one of the window-sashes, which is slidable with relation to the casing A of the window and of such a width from side to side as will permit of turning between the partingstrips of the casing. The sashes are guided by the grooves or channels A within which are fitted the slide shoes or blocks A To these slide shoes or blocks the sash is pivoted at about the center by suitable centerpins. The slide-shoes are formed with channels 13, extending vertically, and corresponding channels B are made in the sashes. IVithin these channels in the sashes are fitted the lock-plates B preferably made of metal and of a thickness which will permit them to be moved into the channels B in the slide-shoes, so that when in this position the sashes and slide blocks or shoes will be locked together and will then be slidable up and down in the channels in the casing in the manner of an ordinary window. When thelock-plates are moved into the channels B in the sash, so as to be disengaged from the sliding blocks or shoes, the sash will be free to turn about its pivot-pins, as before described. These lock rods or plates vB are provided with inclined slots a a near their upper and lower ends, and these slots fit over pins a which are fixed in the sashes at each side, near the upper and lower edges, and upon these pins the lock bars or plates ride and raise and lower as moved inward and outward, owing to the inclination of the slots. It will be understood that as the lock plat-es or bars move downward and outward they enter the channels B inthe slideshoes, and thus lock the same to the sashes.

In the channels B of each sash,nearits lower edge, is fitted a stirrup or' guide C, within which the lower portion of the lock bars or plates work. That portion of the lock plates or bars working in said stirrup or guide is provided with a T-shaped opening C, within which is fitted the head C of the releasingrods D. ing in the rear edge of the guides or stirrups C, and the ends thereof are screw-threaded, and onto the same screws the shank D, carrying at its outer end a button or knob D The shank D of the releasing-rods. works through transverse openings 12 in the sash, the knob or button D projecting slightly beyond the inner edge of the sash. The shank D is held in place and prevented from being unscrewed from its rod D by means of the keeperplate 17, which plate gives a finish to the sash at this point.

When it is desired to raise the lock plates or bars B in order to disengage the sash from the slide shoes or blocks, it is only required that the releasing-rods D be drawn outward by drawing the knob or button D at each side of the sash outward, Fig. 2. IVhen thus moved, the enlarged head C pulls against the inner wall of the opening C and forces the lock bars or plates inward, causing the same to ride upon the pins a and move upward within the channels B of the sash. To relock the parts, the knobs or buttons D are forced inward, which movement forces the head C against the outer wall of the opening 0 and causes the lock plates or bars to move downward and outward into the channels B of the lock shoes or plates. When the releasing-rod is thus forced inward to cause the locking of the sash and slide-shoes, the knobs or buttons are all that is noticed to distinguish the sash from These rods extend through an openan ordinary slide one. The said knobs or buttons serving merely for the purpose of a handle by which to actuate the releasing-rods, the same may be constructed in any suitable manner or ornamented as desired.

Having thus described the invention, what I claim as new, and desire to secure protection in by Letters Patent, is

1. In a window of the described character, the combination with the sashes, of the slide blocks or shoes, vertical grooves or channels in the slide-shoes and the edges of the sashes in line with each other vertically, the vertically-slidable lock-plates fitted in said grooves or channels, of transversely-movable releasing-rods working through the sashes, and of a free or movable connection between the inner end of said releasing-rods and the lockplates whereby the inward and outward movement of the releasing-rods serves to vertically move the lock-plates out of and into engagement with the slidesh0es.

2. In a window of the described character, the combination with the sashes, of the slideshoes, vertical grooves or channels in the slideshoes and edges of the sashes in line with each other, slidable lock plates fitted in said grooves or channels, said lock-plates having inclined slots therein at their upper and lower end portions, pins extending into the channels or grooves of the sashes and upon which the'lock-plates ride as moved inward and outward, a" T-shaped slot in each lock-plate, a

transversely-movable releasing-rod working through the sashes, said rod having an en larged head fitted within the opening of the lock-plates.

3. In a window of the described character, the combination with the lock-plates, of the transversely-movable releasing-rods for actuating the same, said rods comprising, an enlarged head fitted within an opening in the lock-plates, a screw-threaded stem extending therefrom, and a knob or button having a shank screwed onto the screw-threaded stem, said releasing rod working through transverse openings in the sides of the sashes.

4. In a window of the described character, the combination with the lock-plates fitted to move in vertical channels or grooves in the sashes, a stirrup or guide secured within said channels or grooves, a releasing-rod working through said stirrup or guide, the same com- .prising, an enlarged head fitted within an opening in the lock-plates, a stem extending from said head and a knob or button secured to the outer end of the stem,-said releasingrods working through transverse openings in the sides of the window-sashes.

In witness whereof I have hereunto set my hand.

WILLIAM H. TALBOT.
