GEORGE F. BLACK, OF BALTIMORE, MARYLAND,

COMBINED SASH HOLDER AND FASTENER.

To all 'whom t may concern.'

Be it known that l, GEORGE F. BLACK, a citizen of the United States, residing at Baltimore, inthe State of Maryland, have invented certain new and useful Improvements in Combined Slash Holders. and Fasteners; and l do declare, the following to be a full, clear and exact description of the invention, such as will enable others skilled in the art to which it appertains, to make and use the same.

This invention relates to a combined sash holder and fastener.

The object of the invention is to provide a novel device of this character which is of such construction that it will hold the window open when itis one position, and when reversed to another position, will re tain the window in locked position, that is when the window is closed.

Another object of the invention is to generally improve upon devices oi this class by providing one oi' extreme simplicity, one which is highly eilective in operation, one which is easy to manipulate, one which will not inar or bruise the woodwork as the majority of devices of this class do7 and one which is extremely inexpensive to both the manufacturer and user.

Other objects and advantages of the in vention will be apparent during the course Vof the following description.

In the accompanying drawings forming apart of this specification and in which like numerals are employed to designate like parts throughout the same:

Figure l is an elevational view of a device constructed in accordance with my invention, showing the same applied and disclosing the position it takes when it is ineffective.

Fig. 2 is a view showing the position the device assumes when holding a window in the window in closed position.

Fig. 3 is a view showing the device reversed, which position it assumes to retain the window in closed position.

Fig. l is sectional view taken on the y line 4-4 of Fig. 3, looking in the direction Fig. 2.

Specification of Letters Patent.

F ig. 6 is a detail perspective view 'of a device constructed in accordance with my invention disclosing one method of making the same.

Fig. 7 is a like view showing another method of making the device. v

In the drawings for the purpose of illustration, I have shown a portion of a window frame, designated bythe numeral l, and portion of a window which slides in the trame, being designated by the numeral `2. M y improved device is to be applied on the window in such a position as to engage the window frame.

rlhe device comprises a fiat metal triangular plate 3 provided with a centrally disposed slot 4l which extends from a point adjacent the base of the triangle, to a point adjacent the apex thereof. In addition to this slot, the plate is further 'provided' with a plurality of ears 5, two of which are at the corners of the plate, and the other ol which is at the apex of the plate. Each of these ears'projects outwardly beyond the two converging edges of the plate, andthe edge of each ear is rounded in the manner shown.

Carried by the two ears adjacent the base of the plate, are cylindrical lugs 6 which serve a purpose to be described and also serve as knobs or handles, as will be hereinafter more thoroughly set forth. Carried by the remaining ear is another lug `7 .of arcuate formation. These lugsin conjunction with the ears form a plurality oi' friction shoes which are spaced from one another andare designed to engage the window frame l in the manner shown. By this arrangement it is possible to reverse the plate to either of the positions shown in Figs. 2 and 3, and in either of these positions a two-point contact will be had. is to be laid on this two-point contact feature because of the fact that it insures effective operation of the device. To describe this Vfeature more thoroughly it may be said that because of this construction the Vfriction shoes will obtain an effective grip von the window frame regardless of whether or not there are slight irregularities on the frame. It may be stated` that on some window frames there may` be projections in Patenteiimv. 9,1920; Application filed May 13, 1920. Serial No. 381,140. l

the form of hardened paint, tacks, and the like, and if the edges of the plate were corrugated orsmooth, an effective grip would not loe had due to the fact that the edge of the plate would not engage such irregularities but would merelyslipV over them' and not take hold. W ith my construction this is not thelrcase, because the,

friction shoes extend outwardly from the divergent edges of the plate, consequently the shoes will at all timesobtain an effective grip -whether or not there Aare irregularities on the window frame. This' is a, feature of construction to be carefully considered. Close examination of the disclosure of the devicecwill disclose'the fact that the' curved working surfaces of the lugs 6 and ears 5 are flush with one another. .By working surfaces I meanthesurface of these parts which frictionally 'engage the window frame. Due to Vthis manner of constructing the friction shoes, it will be seen that the shoes cannot mar or bruise the woodwork'as the majority of devices of this class do. This is another feature of vconstruction to be carefullyconsidered. rThe 'lugs 6 in addition to forming a part ofthe friction shoes, serve as knobs or handles, kby'means ofwhich the plate is reversed from the position shown in Fig. 2 to the position shown in Fig., 3. v

In thel construction of inv device so far described, it will be' seen that the plate 3, ears 5, and the lugs 6 and -7 are made of a single casting. This isone way of making the device, but I do `not desire` to limit myself to this method of construction, be

cause it may be made in the manner shown in Fig. 7.v By referring to this figure it will be seen that the device is stampedfrom sheet metal. For the sake of convenience and clearness of description, I will place the same reference characters on this form of my invention as are employed to designate the several parts of the forni of Vmy invention shown in Fig. 6. n

' In use, the plate 3 is fastened upon the window frame 2 by means of a screw or the like 8, the latter extending through the slot 4'in the plate. In its normal position, the device will take the position shown inFig. 1, wherein the screw 8 is at one end of the slot 4. It is for this reason that I form the lug Tof arcuate formation. To explain, it is to be said that by-so forming the lug, a clearance space for the head ofthe-screw 8 will be had. If it is desired to hold the wini dow in an elevated position, one of the'friction shoes, which serve as handles, may be gripped and the plate krnoved to the position, shown in Fig. 2. This may be done by merely pushing the plate upwardly from the position shown in Fig. l. l Vhen in this position the slot 4 is inclined toward the window frame, and vshould the window move action will be obtained, it may be necessary to hold the vdevice Vagainst movement with one hand while the window is moved slightly downwardwith the other hand. Thispractice will prevent the` device from dropping,

due to its weight,-to an ineffective position,

as it might do ify it were not held in the foregoing manner. ToV retain the window in locked position when it is closedfit is obvious that it is only necessary to reverse the position of the device from that just described to the position shown in'F ig. 3, Y

wherein the base of the triangular Vplate is swung upwardly. When in this position the slot'4 will-be inclined at a different* angle, consequentlyif an attempt'is made to raise the window, the Vscrew acting in the slot will force the friction shoes into effective engagement with the window frame and prevent the window from being opened.

A device constructed in accordance with my invention will be found extremely novel and advantageous, due to the fact that the friction shoes will always obtain an effective grip on the window frame regardlessof whether or not the latter has any irregularities thereon. It may be stated at this point, that in many cases there is a weather strip secured on the window frame, consequently there is a slight space, in some cases, between the weather strip and the window. Because of this, it is necessary that the plate be ofsuilicient thickness to prevent it from working into this space and not obtaining a grip. WithV my construction I overcome any such circumstances because the lugs 6 and 7 project far enough beyond the'pl'ate to 'prevent this. My device is extremely simple and easy to manipulate, andis inexpensive.

I am aware that devices of similar construction to mine are patented and are in use, but I do not know of any device that possesses all the constructional Vadvantages that my device does. u

A oarefulconsideration of the foregoing description will enable persons skilled in the art to which this invention relates, to obtain a thorough'understanding of the same, therefore, further description is deemed unnecessary.

I claim:
