HARRY E. ROGERS, OF ST. LOU

Application filed IToveiiiberl 16, 1921.

IS, MISSOURI, ASSIGNOR OF ONE-HALF TO l'OI-IlilL ONEAL,

0F ST. LOUIS, MISSOURI.'

SASH LOCK.

T 0 all whom t may concern.'

Be it known that I, HARRY E.

Roenes, a

citizen of the United States of America, a

resident of the city of ofY Missouri,

St. Louis and State have invented certain new and useful Improvements in Sash Locks, of

which the following is a act description, accompanying drawings, this specification.

reference being` full, clear, and exliad to the forming a part of This invention relates to improvements in sash locks, and more lockingv device adapted for use particularly to a on a window having an upper sash and a lower sash. The main object of theinvention is to produce a strong, simple and inexpensive sash lock that can be easily and quickly applied to a window. A further object is to produce a lock of this kindwhereby the upper and lowerr sashes can be forced toward each other.

With the foregoing and other objects in view, the invention comprises combination and arrangement of struction,

the novel conparts hereinafter more specifically described and illustrated in the ac companying drawings wherein is shown the preferred einbodiment of the invention. However, it is to be understood that-the invention comprehends changes,

variations and modifications `which come within'y the scope of the claims hereunto appended.

Fig. I is a vertical section illustrating portionsof a window equipped with a sash lock' features of this invention. front elevation showing the window.

embodying the Fig. IIis a sash lock applied to a Fig. III is a horizontal section on the line III in Fig. II.

Fig. IV is a perspectiv e view showing the tubular bolt-receiving nienber and one end of the locking bolt associated A designates an upper a bottom rail 1 and a sti a lower sash having a 4. As shown by Figs.

therewith. sash provided with le 2. B designates top rail 3 and a stile I and II, the window casing C is provided with the usual vertical uideways for the saslies.

The locking guide or bearing 5 hav seated on the top of the cured thereto by means pass through said ianges.

device comprises a tubular ing side {ianges 6 lower sash and seof screws 7 which A locking bolt 8 is slidably mounted in the guide 5 and provided with a lateral projection 9 adapted to extend through a longitu dinal slot 10 in the Serial No. 515,442.

guidee. AV transverse slot 10 is formed in the tubular guide 5 so as to communicate with the slot 10, and the projection 9 is movable in an angular path, or passageway, formed by said slots 10 and 10. As shown by Fig. I, the slot 10 is open at the inner end of the tubular guide 5, so the locking bolt canbe easily applied tov said guide, and when the device is secured to a window the bolt cannot be withdrawn from the guide.

D designates a bolt-receiving member, or keeper, cated in the stile of the upper sash A and adapted to register with. the bolt 8. This tube is providedwith coarse, external screw threads extending from one of its ends to the other and adapted to be screwed into the upper sash. Thissash canv be drilled, or bored, to receive the tube D, and said tube can then be very easily screwed into the sash, as will be hereafter described. The outer end of the tube D is preferably flush with the inner face of the sash.

As shown most clearly by Figs. I and IV. the tubeD is provided with an angular slot 11 adapted to receive a lateral projection 12 extending from the bolt 8. A portion of this slot is parallel with the longitudinalv slot 10 in the guide 5, as shown by Fig. Land this portion of slot 11 is open atthe'exposed end tion can be moved from. the vertical position shown by full lines to the horizontal position shown by dotted lines. It can also be moved longitudinally of the slot 10 when it occupies the horizontal position. It will therefore be understood that one end of the locking bolt 8 can be readily inserted into and removed from the tube D.

When the projection 10 is moved upwardly from the position shown bvdotted lines to the position shown by full lines. the bolt 8 is turned and its projections 9 and 12 cooperate with the tubular members 5 and D to force the sashes toward each other. To accomplish this, the slot 10 is provided with an abutment face 13 (Figs. I and III) adapted to engage the projection 9. and the slot 7 has an abutment face 13 (Figs. I and IV) adapted to engage the projection 12, said face 13 being in the form of a cam. I'Vhen the projection 9 is moved upwardly in the form of aV tube preferably loico to the position shown by full lines in the drawings, it travels along the abutment face 13, and at the same time the projection 12 moves along the cam face 13', with the result offorcing the sashes toward each other. At this time the bolt 8 is placed under tension, and its projections 9 and 12 firmly engage the faces 13 and 13', as shown most clearly by Fig. I.

In applying' the locking device to a win` dow, the locking bolt 8 and its guide 5 can be used as a tool for screwing the tube D into the upper sash. After the upper sash has been bored to receive the threaded tube D, the locking bolt 8 is inserted into the slot 11 whereby it is interloclied with the tube D, and the guide 5 can then be turned to impart a rotary motion to the bolt 8 and tube D, thereby screwing the tube into the upper sash.

To prevent rotation of the tube D, the threads of said tube are provided with alined notches 15 in their peripheral edges and a pointed anchoring member 16, preferably in the form of a nail, is driven into these notches.

I claim:

1. A sash lock comprising a tubular boltreceiving member adapted to be introduced into the upper sash of a window, a tubular guide member adapted t'o be secured to the lower sash, each of said tubular members being provided with an angular slot formed through the walls of said tu'bular members, said slots being of the same Widths thro-ughout their lengths and the slot in one of said members being provided with a cam face, and a locking bolt movable longitudinally in said tubular guide member so as to locate one of its ends insaid tubular bolt-receiving member, said locking bolt having projections movable in the angular slots in said tubular members, and one of said projections being adapted to engage said cam face to force the sashes toward each other.

2. A sash lock comprising a bolt-receiving adapted to be driven into member adapted to be introduced into the upper sash of a Window, a guide member adapted to be secured to the lower sash, and a locking lbolt movable longitudinally in said guide member so as to locate one of its ends in said bolt-receiving member, said locking bolt being` free` to turn in said guide member when said end is located in said bolt-receiving member, one of said members having a slot oit' constant width 'formed through the wall thereof, said slot comprising a portion extending longitudinally ot said member and a curved portion having a cam face and said locking bolt being provided with a projection movable on said cam face when the bolt is turned in said guide member.

8. A sash lock comprising a bolt-receiving member in the form of a tube having external threads adapted to be secured into the upper sash of a window, a guide member adapted to be secured to the lower sash, a locking bolt movable longitudinally in said guide member so as to locate one of its ends in said bolt-receiving member, said locking bolt being free to turn in said guide member when said end is located in said bolt-receiving member, one of said members having a slot of constant width formed through the wall thereof, said slot comprising a portion extending longitudinally of `said member and a curved portion having a cam face and said locking bolt being provided with a projection movable on said cam face when the bolt is turned in said guide member, said external screw threads on said bolt-receiving member Ibeing provided with alined notches in their peripheral edges, and a pointed anchoring member said alined notches to prevent rotation of said bolt-receiving member.

In testimony that I claim the foregoing I hereunto affix my signature.

HARRY E. ROGERS.
