sAsH-srnme- To all whom it may concern:

Be it known that I, Hanny H. Sor-ritorna, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invente@ certain new and useful Improvements in ifiaslrtprings;.and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numbers of reference marked thereon, which form a part of this specification.

lt is an object of this invention to provide means insertible in the sliding sash of a' window adapted to contact the fixed 'weather stripping means on the frame to maintain the complemental engaging means secured on the sash in close contacttherewith.

It is also an object of this invention to provide a device adapted to be secured in practically any position in the stile of the `window sash and affording means preventing rattling of the sash in the frame.

It is also an obJect of this invention to provide a device in which the actuating'elements are inclosed within interlitting` casings and thereby thoroughly protected.

It is also an object of this invention to provide a sliding member capable of slightly differential movement to enable the same to readily adapt itself to inequalities of an uneven Surface..

It is also anfobject of this invention to providea device in which the elements are retained in properv relation by means of a single removabley pin.

It is furthermore an object of 'this invention to construct adevice in which the slidable casing is capable of slight diiferential movement andis actuated by springsl at each end thereof. p y

It is furthermore an object of this inven` tion to provide a device in which' all the elements thereof are loosely engaged therein and the whole maintained together by means of a single pin. Y y

It is iinally an object of this invention to provide a device constructed of simple metal stamping of durable construction, and which may be assembled and installed by persons not having previous experience with the same.

The invention (in' a preferred form) consists in the matters hereinafter described and more fully pointed out and defined in the appended claims.

Specification of Letters Patent. Patentd Jun@ i917, Application filed March l12, 1913. Serial No. 753,767. i

In the drawings:

Figure l is a vertical transverse section taken through a. car window, the sashes of which are equipped 'with a. device embodying the principles of my invention.

Fig. 2 is a transverse horizontal section taken on line Q-Zof Fig. l, showing a con struction of the window post and the relative position and operation of the sash frame.

Fig. is a front elevation of a device shown attached toa window sash.

i Fig. a is a vertical section online Ll-i of Fig. 3. y

Y Fig. 5 is a horizontal section on line 5-5 of Fig. `l.

As shown in the drawings:

Referring to Fig. l, the reference numeral l, designates an outer sliding sash of a car window, of which the inner sliding sash is denoted by the reference numeral 2. The window'is provided with inner and outer transom lights 3 and 4, respectively, which are oii'set on each side of said sliding sashes l and 2, to permit thel same to be raised upwardly between said transom lights when it .is desired to open thewindow. The window post comprises a T bar 5, which has rigidly secured to the iianges thereof, inner and outer channels G, and 7, respectively, said channels ubeing of unequal width so as to receive the extremities of a continuous jamb and cheek. plate S, therebetween.

As shown, the outerA channel or cheek plate 7, is provided at the ends of its side iianges with laterally' extendingrflanges 9, which engage in a suitable recess in the stiles of the outer sash l. The recess in the outer sash l, is'provided byrabbeting the outer edge. of the stile in a; stepped manner, and securing therein and flush with the outer face of the stile, a small T bar or strip of metal l0.

The cheek plate 8 extends inwardly on each side, thereby affording the side walls and end wall of the windowpost. Said cheek plate is providedf4 with longitudinally disposed parallel recesses in they side walls thereof, the walls of. said recesses being acutely angled in converging relation, and

vas clearly shown in Fig. 2, the rear surface of the metal forming the bottom of the recesses ll, have secured thereto, by spot welding or otherwise, the Z bars l2, which are rigidly connected to the T bar 5.

Resilient metallic inner sash stops 13, are

shown engaged in the recesses 11, and stops through for attachment. A cup member 19,Y

is shown inverted in the casing-16, the outside dimensions of said cup member being slightly less than the inside dimensions of said casing 16, to permit a small amount of differential movement of the cup member therein, and to insure easy sliding of the saine. The depth of the cup memberis a trifle less than that of the casing member 16, so that the cup may be depressed within the casing flush with flanges 17, thereof. Said cup membery is provided in the side walls thereof withtransverse slots 20, which are centrally positioned and adapted to correspond with the apertures inthe sidewalls of the casing 16.

A small pin 21, is inserted through the apertures in the casing 16, and the slots 20, of the cup member 19, to engage the cup member and casing together in sliding relation. For the purpose of normally pressing said cup member outwardly, spiral springs 22, are loosely engaged between said members at each end thereof, and in order to maintain said springs in proper position,

a channel shaped bridge member 23,' is sprung within the cup member 19, and extends from the bottom thereof, to a point flush with the edges of the'side walls.

The operation is as follows:

As shown in the drawings, theV device ras connected in the window sash is adapted to bearV against the fixed weather stop flange 9, thereby thrusting the sliding sash inwardly and bringing the members 9 and 10, into close contact 'to effect a seal. Inasmuch as the cupV member 19, is slightly i smaller than the interior of the casing 16,

and isl retained therein by the single pin `21, a small amount of pivotal movement isv to assume differentialpositions. The amplitude ofmovementof said cup members is of course limited by the length of the slot 20. As shown more particularly in Figs. 3 kand 4c, the 'ends and outer edges of the YcupV member are rounded to facilitate op- Y erationof the device.

Of couise, 1 amk aware that details ofconstruction and operation may be varied with-i yout departing from the principlesl of my invention, and 1 therefore do notpui-pose limiting thepatent granted otherwise than necessitated' by the prior art.

l claim as my invention: 1. 1n a device of the class described loosely interfitting cup members one inverted within 'the other, one member aper tured and the other slotted in Vboth of the side walls of each thereof, a pin engaged in said apertures and slots to retain said inembers together, springs loosely engaged in` each end of said iiiterfitting members, and a bridge member sprungwithin one of said cup members adapted to space Vsaid springs in proper relation.

2. 1n a device of the class described, cup members, spiral springs, a pin holding said members engaged to one another, and means bridging said pin sprung within one of said membersV adapted to space said springs in proper relation.

3. ln a device of the class described the Y p combination with a window sash, ofy a cup member disposed longitudinally thereof and recessed thereinto, another cup member inverted thereinto and having a sliding relation therewith, said first mentioned cup member having apertures therein and said second mentioned cupmember having slots therein disposed to register with said apertures, a pin extending transversely through said interfitting cup members engaged in the apertures of the one and also in the slots of the other of said cup members, spiral `springs disposed at each end of said interfitting` cup members bearing against each thereof to normally impel thesame apart, and a spacing member mounted within said second mentioned cup member to maintain said springs properly positioned with respect to one another.

4t. ln'a device of the class described interfitting cup members, the one having slots therein and the Vother having apertures therein, a pin extending transversely through said cup members engaging through said respective slots and apertures to permit a 'simultaneous' pivotal and sliding movement of one of said cupmembers with respect tothe other, springs disposed within said cup members acting normally te resist pivotal Yand sliding movement therebetween, and means' bridging said pin to hold said springs in position.

In witness whereof I have hereuntoV subscribed my name in the presence of two subscribing witnesses. Y
