T0 all whom, it hwg] concern:

Be it known that l, .MYnoN CossEY, a citizen of the United Statespand a resident of the boroiighof Brooklyn, city of New York,

State of New York, have invented certain new and useful Improvements in Door Carrying and Operating Devices, of which the following is a specification.

My invention relates to im rovements in door. carrying and operating r evices, and is especially well adapted for eases where it is desired to move two or more doors simultaneously in the same direction and at varying invention, however, is not limited to moving the doors simultaneously in the saine direction, but, on the contrary, is adapted, if modified, toniove them simultaneously in opposite directions and at varying rates of speed. li'li'ireovcr, my invention may be a )plied to doors moving vertically or upwardly, as well as laterally or in In the present case it is illust-rated and described as appliedto laterall}-'movable doors. The-relative speed of the di ors may be varied. Thus one door may move twice as tast as the other, or it may be made to move either more or less than twice asV fast.

l have found from experience that wherever operating mechanism is utilized to trans mit movement from one door to another it is important, il'v not-essential, to prevent the transmission ot' strains from anv of the doors tothe operating mechanism. lf the operating mechanism directly or indirectly connects doors which are either moving in the saine direction and past each other or moving in opposite directions and toward each other, any breakdown of the operatingdevices will result in rendering impossible any movement of the doors without a com lete destruction o f the operating devices. y the use of my invention I prevent transmission of. any strains to the operating devices both-when the doors arein normal operation and also in Obviously the device for prevention of transmission of strains may be placed, strictly speaking, intermediate the .doors and operating mechanism or may be nierelv so constructed with respect to the doors and the operating mechanism and to produce the same general result.

ln the a cimpanying drawings, Figure l shows diagrai'nmatically my invention applied to three sliding doors arranged to move and antifriction devices.

in the same direction.A F ig. -2 shows diagrammatically my invention applied t0 two doors arranged to move'in opposite directions. Fig. 3 shows a gear-wlieel adapted to be used in a modification of my inveiition.`

F igs. 4, 5, and 6 are front elevations of a construction embodying a preferred form of my invention and showing two doors sliding in the same direction and in three different positions. Thus 4 inFig 4 the doors are closed, in Fig. .5 they are partially open,vand in Fig. 6 they are entirely open'. Fig. 7 is a top or plan. View" with the parts in the positions shown in Fig. 4. Fig. S is a view, partially in section and partially in plan, showing the same construction illustrated-in Fig. 7, but

with cert-ain parts removed to show more clearly the arrangemeiit of the racks, gears,

K Figi) is a crosssection on the line S) 9 of Fig. 4, and Fig. 10 a cross-section on the line 10 l0 of Fig. 4.

Taking up, now, the diagrammatic views,

F ig. l'shows three sliding doors moving 1n A the saine direction, the door AL movingwith twice the speed of the door A and the door A3 moving with twice the speed of the dooi A2 or four times as fast as the door A. These results are brought about as follows: The doors A', A?, and A3 are hung, respectively, from the sliding bars D', Dla'nd D, these bars being supported in any suitable manner to permit of longitudinal reciprocating motion. The bars D and D are provided, as shown, on their upper sides with rack-teeth. The bar D is provided with a gear-wheel B', rotatably mounted thereon in any suitable manner. This gear-wheel meshes, as shown, with the movable rack lD2 and, further, meshes with the stationary rack C. Considering now the effect of the mechanism so far' described with reference to the relative movement ot doors A and A2 and disregard in; for a moment the door A, it-will be seen that when the door A is moved in the direction of lt-he arrow-that is to say, to the left-it will cause the gear-wheel B to rotate in a clockwise direction, due to the fact that it. meshes with the fixed rack C and that such rotation of the gear-wheel compels the movable rack l.)2 and the door N, suspended therefrom, likewise to move tothe left and in the same direction as the door A. Moreover, the,

IOO

door A2 will move with twice thc speed of the y door n'. Referring again to Fig. 1 and considering now the relation of the door A to the others, it. will be'noted that the door A is rio geared to 'the door A2 in precisely analogous fashion to the manner in which door A2 is geared to A. In other words, the door A3 is suspended from a slidable rack, D3,.corre spending with DZ. A gear-wheel Bz is rovided corresponding with the gear-whee B 'and is mounted in similar manner thereto,

and a fixed rack C, corresponding with the .rack C', is also provided'to mesh with said gear-wheel. The effect ofthe operation of this duplicate mechanism is also the same as before, which is to compel the door A"l to move with twice the s eedv of' the door A, or, in other words, with our times the speed of the door A'. I

Referring to Fig. 2, my invention is there shown diagrammaticall as applied to two doors which are compeled to move in opposite directions, one twice as fast as the other. This result is attained, as will be seen.' by a comparison of Fig. 2 with Fig. 1, by locating the movable rack and the fixed'rack on the same side ofthe gear-wheel. Thus, referring still to Fig. 2, C is'the fixed rack, andDz the movable rack, both -located on top of the gearewh'eel B and ofcourse arranged to meshv therewith. The gear-wheel B', as before, is mounted on the movable bar D, which in turn supports the door A. Again, as before, the movable rack D2 supports the other door A2. When the door A is moved to the left, for example, it will be seen that tne fixed rack C will compel the gear-wheel B to rotate in a clockwise direction, which inturn will compel the movable rack D2 and the door A2 to move to-the right and awa from the door A and with a speed twice as ast.

Thus far all the constructions describedv have shown one door moving twice as fast as its adjacent door. This, however, is not a necessary condition, because by a simple modification of the gear-wheel the relative speed of the doors either in the same or in opposite directions can be varied at will. One

method of doing this consists in substituting for the gearwheel B', for example, in Fig. 2, thc duplex gear-wheel shown in Fig. 3. This duplex wheel consists merely of two gearwheels of different diameters rigidly con-v nected. The effect of the substitution of the duplex wheel upon the relative speed of the doors will depend upon whether the larger wheel or the smaller is made to mesh with the lixed rack. Thus if the large wheel X' be made to mesh with the fixed rack C and the small wheel Y with the movable rack D? then the movable rack, and consequently the door A2, will move less than twice .as fast as the door A', the amount of dierence in speed Vdepei-iding upon the relative size of said The oregoin description4 of' the diagram'- matic views of ies. 1, 2, andfS vwill now makedoor either more orless than twice and more than e ually as fast asanother.

the practical worlbring constructions shown inthe remaining figures easily understood.

In the practical operation-0fA myinventionit is desirable to provide somemeans for preventing the transmission-of strains from the doors' to the racks and gear. A preferred means for this purpose is to provide-a doorhanger comprising two outer bars or guides, which constitute one element, and an intermediate bar,;whch constitutes another elel ment, with antifriction devices between the outer bars or guides and theintermediate bar. One of" these elements is designed to have endwise movement with respect to the other, and in the present case I have, as illustrated in Figs. 4 to 10, shown the intermediate bar movable with respect to the outer Y bars or guides. Thus in t e said figures it will be seen that there are two doors shown, A and A2, the door A being connected by links 1 1 to a movable bar D', which bar is slidably supported upon antifriction devices between the fixed bars or guides 2 and 3. As

shown, these antifriction devices comprise balls 4, which are loosely held in fixed rela a ball-carrier 5, the balls themselves running in longitudinal grooves 6 and 7 (see Figs. 9 and 10,) located on the respective edges' of the fixed bars or guides 2 and13. readily be understood that the bar D might beifixed and become the guide and 'the bars 2 and 3 b'e movable. Of course in this eveht the links l would have to be connected to the bars 2 and 3.

As shown more clearly in Figs. 9 and 10, the antifriction devices or ba s serve not only as antifriction devices, but also vto retain the intermediate bars in operative position with regard to the outside bars 'and prevent any movement between the movable element and the fixed element at a right angle to the endwise movement. This has several advantages. In the first place it does away with the necessity of any other retaining means, and in the second lace it affords an absolutely sure means of eeping thev intermediate bar in its roper relation to the out side bars and algo permitting va certain amount of flexibility. Furthermore, in the event of any one of the doors striking an obstruction during movement the resulting strains are distributed over all the balls,

tion to each other in a well-known manner by l n will esame l a which obviously reduces the strain .on any one ball. The aforesaid movable bar D' carries a pair of guides 8 9, similar to thc other guides 3, already described. ln the precise foi-m shown, Figs. 5 and 10, these guides 8 and 9 are each rigidly secured to a common'basr-iplate D* by bolts or rivets a, and the baseplate l)4 is secured to the movable bar D', so as to move with it; One ol' the linksl may be utilized to connect the bar 1)' and baseplatc D, as indicated in Figs. Sand It), or they may be connected together by other means. able bar D?, similar to the movable ba'r D' and adapted, like D', to slide back and forth between the guides 8 t) and running, as before, on balls 10, located in the longitudinal grooves il l2 (see Fig. 10) and held together by the ball-carrier 13. Like D', the movable bar l)g is connected to a door, in this case A, through the links 14. AY rack D3 is rigidly -secured to the movable bar D2, the teethof said rack engaving the under side of a gearwheel B', aswill be more fully described llereinafter. Thus the construction just described in detail will be seen to comprise two doors, A' and A2, the door A being connected to a bar D, slidably mounted on antifriction devices between fixed guides 2 3, and the door A2 being likewise connected to the movablcbar D, slidablj.T mounted on antifrictioi: devices eta een the guides o El which guides are connected to and carried by the aforesaid movable bar D', to which the other door A. is connected. The particular l'orm ol mechanism which' l have shown for connecting and mutually operating these doors com- )rises the rear-wheel B" rotatztblv mounted l is i on and carried by the movable. guide 8, which inturn' is ri idly secured to and carried by the Inova le intermediatr` bar l)', which carries the door A'. This gear-wheel B' meshesboth with the tiXe-d rack (7 and also with a movable rack D, which is rigidly secured to and practically forms part of the movable intermediate bar D2, whi'cliin turn supports the door A2. (h msequently when either the door A' or the other door A'-' is moved to the left, for example, the other door must necessarily move in the same direction and the door Afmust always move at twice the rate of speed as the door A. ll' the moving power is applied to the door A', the movable bar D' must also move and d'rag after it the gear-wheel B', which being compclled to rotate by the fixed rack (l' drives the movable bar D2 through the intervention of its rack which isiin mesh with the said gear-wheel, and' thus drives the bar 1) and its door A2 in the same direction as the door A', but with twice its speed. lt will be noted (see particularly Fig. lll) that the guides S t), mounted on the movabic bar l)', are not iii the same vertical plane as the other pair ol guides 2 2i. This permits the movable bar Moreover, there is provided a mov- D2 and its door A2 also to occupy ditlerent planes from the movable bar D' and its door A', so that the door A is able to slide in iront of the door A without interference. l-laving described my invention, I claiml. ln a door carrying and operating device, the combination with a plurality of doors of operatingr mechanism adapted to transmit movement from one door to an' other and means arranged to'prevent transmissions of strains to said operating mechanism. v
