'The present invention relates to .gates and particularlyto gates for elevator cars.

One feature of the invention is to provide a gate which is `ca able.of covermg a Still another feature is to provide ay gate which is positive and reliable in operation which may be operated with a minimum of effort, which is of rigid construction and which may be cheaply manufactured and Other features and 'advantages will be- I come apparent from the following description, takenfin connection with'the accompanying drawings wherein the mventlon 1s embodied in concrete form and in which Figure 1 is a view in elevation, with parts broken away, of one form of gate arranged in closed position on a passenger type ele-y vator car, the car being shown with the top removed and in'section along line 1-1 of Figure 2;

Figure 2 is a plan'view of the same, with parts omitted in order to emphasize certain structural details, with the gate arranged in open position and with the top of the elevator car removed;

Figure 3 is an enlarged fragmental detail taken along line 3--3 of FigureV 1 Figure 4`is an enlarged fragmental detail ytaken along line 1v-4; of Figure 1;

l Figure. 5 isan enlarged fragmental plan view of a portionof the gate, illustrating the manner in which the gate turns around a corner;

Figure 6 is a view similar to Figure 2 of the gate arranged in open position on a freight type of elevator car;

Figure 7 is aview similar to Figure 1 of another form of gate,

p Figure 8 is a View 'similar to Figure 4 of the gate shown in Figure 7; and

yFigure 9 is an enlar ed fragmental view of the gate shown in shown in section to emphasize certain structural features,

The form of gate illustrated in lFigures 1 to 5 is composed of a plurality `of vertical tubes 10 connected4 by hinge members 11.

of any with in anl enclosure when in c osed position and of uncoveringv igure 7, parts being P lone at the bottom and one in the mi dle.

Each'hinge member comprises a yoke 12, a pair of lugs 13 extendingoutwardly therefrom and a slmilar but oppositely extending pair of lugs 14,:A wider space isprovided etween the lugs 13 than between the lugs 14.111 order'to permitthe lugsfglt on the adjacent hmge member to extend therebeltween. Apertures 15 are 'gprovided in lugs 13 and slmilar apertures lf3-in lugs 14,.-

With adjacent hinge members in assembled relation., the-apertures 15 and '16 are-,in 'vertical ahgnment sowas to ,receive-'one of the4 tubes 10.' Each hinge member is secured. to

Va .tube as by means of-pin's y17 extending.V

through lu'gs 14, vHowever,the hinge meml bers are not pinned to `thejtubes lthrough the .lugs 13h, they bein'g freeto `iturn at these points. In this'manner eachfctube isvhinged to its adjacent tubefwithg .the hinges maintained in position by the .pins 17.

Each tube 1Q extends-upwardly into` a hanger, the `hangers for t el intermediate tubes being designated"*18. 'As clearly shown for one of the intermediate tubes inr the top of the jboss 2O to form a vertical bearing for the tube. The frame of the hanger is formed with a yoke portion 24 and two sides 25 and 26, theside 26 lsupporting the boss 20. A roller 27 is supported between thesides of the hanger as by a pivot pin 28, the pivot in in turn being maintained in position y a Apin 29. Thesey roll ers ride on the track 30. As shown in Figure 2 in a passenger type car, the track 30 extends across `the front, bends at the front left-hand Vcorner and continues along the side of the car to the rear thereof. The track may be supported in any suitable manf ner, as by studs 31 extending from plates 32 secured tothe car at intervals along the ath just described. It is to be understoodA that, if desired, suitable reinforcements may be arrangedon the car to facilitate the support of the track. This track acts both as a support and a guide for the gate.

The construction of the end hangers r19 is' slightly modified, one of the end hangers 'being illustrated in Figure 3., The con-V struction of the top of the hanger is the same as above described .for one of the 1nvtermediate hangers. ,Atf the bottom how-- ever, a portion 33 of the'hanger extends upwardly from the boss 34. 'An additionall roller 35 is sup ortedl bet-ween'the side 36 and portion 33 y a pin. 37. For lightness ofl construction, the lframes of the interme diate and end hangers are preferably of. channel shape, as indicated by the broken away portions infFiguresB and 4 and in Fi re 5.

wardly into a channel 3 8. .This channel acts as a guide for the bottom of the 'gate, the

channel'being of the same contour as the overhead track 30. Flanges 40 are formed on the sides of the channel, the channel be#- 'ing secured'to the floor 41 of the car as by .screws 42 extending lthrough the. channel.

' -A plurality of apertures 43 areformed in tion of the gate. A false. panel 45 is arthe bottom lof the channel, coincidin =aper' 'tures' 44 bein formed in the 'car allow' dirt to all-through. Otherwise suflicient dirt or-other matter might accumulate in the channel to prevent the proper operaranged in the car parallel with the left-hand.` side thereof. The panel may .also extend a short distance to the right vat the front of the car, as illustrated. Theportions ofthe track 30 andchannel 38 at the left'front and side of the car extend between the ,panel and the car. I

The lugs 14 of the rightfhand hinge mem ber in each row are connected by a'bumper plate 46. Bumpers 47 are secured to the side of the car and disposed in .the paths of these bumper plates. Similarl the lugs 13 of the left-hand hinge mem ers in 'each row are connected by a lbumper plate 48. Bumpers are secured Ato the car at the rear in the paths of these plates;

.It isto be understood that, if desired, the

track 'and'rollers may Vbe 'arranged'at ,theVA bottom 4of the gate with the channel disposed.

at the top. It is to be further understood `that the gate .may be power or manually op-` erated, no power means being shown for convenience of description.

. With the-gate arranged for manual o eiation .and in closed "position as illustrate in Figure 1, to open the -gate the yoperator'may grasp one of the tubes 10, lpulling the gate to the left. The left-hand tube 10 is illustrated in Figure 1 as substantially on the vbend of the track. '1U on movement of the gate to the left, the r'o lers 27 and 35y of the left end lhanger are' guidedby the track around the corner, 'Figure 5- illustrating the different positions which Vthe various parts may assume'.v The left len'd hanger 19 pivots on a vertical axis as its rollers turn the cor-- he bottoms of the tubes 10 'extend downoor, to

ner. lAs previously explained, the left end tube l0 -is free to turn in` the lugs 13 of the left end hinge members and in the hanger but the adjacent or next tube to the right is secured to the lugs 14 of these hinge mem bers. The movement of the left end tube around -the corner is permitted by the plvoting of the second tube within the apertures in lugs 13 of the adjacent or second hinge members and hanger. The successive tubes, hangers and. hinges act in a similar 'manner during the continued movement of the gate -around the corner. The track 30 and channel 38 guide the gate` between the side oflthe car and the panel4 45. Upon the gate reachingits open position, it is stopped.

y the lengagement of the bumper plates 48 and bumpers 50. It is to be understood-that the bumpers are made of material suitable toabsorb anyshocks. The gate is illustrated in its open'position inlFigure 2. It is `.to be noted that the right-hand end' tube 10^ex tends slightly `out from l behind the pan'el with the gate in open position. The gate may be closed by reverse operation, the operator grasping the `right-hand tube, pulling the ate to the-right. As the gate reaches its c o'sed position, it is stopped in a similar manner by the engagement of bumper plates 46 and bumpers 47,. The rollers 35 prevent loo' movement.. Should the car be too deep, the

bumpers 50 may be arranged on a properly located partition between the side of. the car and the false panel. It is to'be understood that the gate is equally adapted for the cars which are controlled by the passengers them` selves.v V l l It has beenfound in actual .practice that the gate operates with very little noise. Due to the fact that the tubes 10 aremaintained separated at all times, the danger of injury to the operator or passengers such as pinch- *ing of the hands or fingers is substantially eliminated., Furthermore due to the. fact that the gate uncovers the Whole of the pas` sageway into the car when opened, the traffic ma be handled'with maxnnum despatch.

In. igure 6, the gate is illustrated as arranged on a freight type of elevator car.'

The structuralI details of the gate are substantially the same'as those above described. ,The track 55, however, is" mounted on the .A

outside of the car, being secured in a manner similar to that above described by studs 31 and plates 32. Thus with the kgate mounted lon the track, the sides 26 and 36 of the hangers are on the outside. The channel .56 is illustrated at the side of the car with the flanges removed in order that'the gate may be 'mounted outside the car without undue consumption of the hatchway space.v The channel may be secured to the side of the car by studs and .plates in the manner emoutwardly. As illustrated cept on the turn,

ployed to secure the track. Also the outer flange of theA channel in front ofthe car may be omitted, as illustrated. v Bum ers 57 and 58 similar to those described or the passenger car may be providedif desired.-

The gate is operated in the lsame 'manner as described for the passenger type car, the gate being illustrated in its open position. It is to be noted that, in this position, the right-hand end tube and bracket. areto the left of the side of the cary thus presenting an opening of the same width as the inside of theear. y

Referring to Figures 7 .and 9, the gate therein illustrated for a passenger type of car, is formed of upright channel members 60 arranged with their flan s extending in igure 9, exthe flanges are in abutting relation, thus presenting a closed type of gate. hinge members 461 arranged in three rows. With the exceptionvof the right-hand hinge members .of the two lower rows in Figure each hinge member is formed of two spaced lugs 62 and a single lug 63 connected by the plate 64. Each hinge member in each row is secured, as by rivets 65, to one of the channel members 60. The single lug.63 on each hinge member'extends between the lugs 62 on its adjacent hinge member, being joined by hinge pins vextending through apertures 66 provided in the lugs. The hinge pins 67 for the two lower rows of hinge membersare formed at theirtops with ositioning heads 68. The hinge pins 70 or the to row of hinge members are formed wit lianges 71 at their bottom ends which act as supports for the gate. The hinge pins 70 extend upwardly into the hangers 18 and 19 where they are pivotally secured in the same manner as previously described for the tubes 10. Tins 72 are riyete'd or otherwise secured to the bottoms ofv the channel members 60. These pins extend into 'thel channel 38 to guide the gate at the bottom. ven the gate is closed, the right-hand channel member 60 extends partially into a channel 73 secured to the side of the car. The lefthand channel member 60 extends partially .behind the front portion of the false panel 45.l In this manner the passengers view of vthe hatchway is completely'shut 0H. This is of particular advantage in high speed elevator systems as visual realization of rap- 'left-hand hinge members 61 to engage bumplers 77 are arranged the channel membersuponv occurs before the'y'emerge .handle 74 is just to The channel members are )oined by idly passing the successive floors is 'very annoying 'tosome passengers. The right-hand channel 'mem-ber may bel provided" with a. handle`74v to facilitate the pening and c losy in operation'. v

umper plates 75 join' the"lug's62 of the ers (not shown) when the gate is movedinto openposition. A bumper 7 6vis secured to the car at the to thereof, being disposed:

`in thev path,v ofthe ugf63V of the right-hand hinge member" 61.' "Eherlght-hand hinge members forv themiddle Aand bottomr'ows are formed with Athe lugs 63 omitted. Bump, y in horizontal alignmen-t with the'` middle and lower-rows of'hinge members to engage the ,outer flange of the right-hand channel member.

Upon movement of the gate, the channel members spread apart at the turn. It is 'to be noted,however, that'the reengagement of closing the gate from behind the front portion of the false panel 45. Thus in'ury to the operator or passengers such as mlght result from' catching ythe lingers in between the channel members is prevented.

With the gate in full open position,

panel, presenting substantially a full opening. Thus with 4the closed type of gate also, traffic may be handled at each 'stop a v minimum of time. 4

Gates 4constructed in the above describedmanner may be designed'to 'turn very sharp corners, the sharpness of the turndepending on the dimensions of the various 'parts employed. In practice-a two and one-halfinch radius 'for the curve at thev corners has been found satisfactory. Y I

As many 'changes `could be made in the above construction and many apparently widely different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accom anying drawings shall be interpreted as "il ustrative and not in a limiting sense.

1. In a gate, a hanger, an integral hinge member, a vertical member securedA to and extending through saidhinge member and having ya swivel d connectionat its upper end to said hanger, and a second vertical member extending through said hinge member and arranged to turn therein.

2. In combination, an elevator car, atrack secured to said car and extending across the front and along a side thereof, and a gate comprising a plurality of supporting members having ro 1ers arranged to ride on track, a vertical member pivotally supportl ed in each supporting member, said vertical the' the right of the false $I nexnbers forming the body portion oit .the

gate, and hinge'members for securing the adjacent vertical members together.

3. In combination; an elevator car having substantially a full opening across the front; a track secured to lthe car at the top thereof,

Said track eirtending across .the front of the` car, bendin at one corner and continuing across the front of the car and around to vsaidside in vertical alignment with said track, the tubes of said gate extending downwardly into said channel; and a false panel arranged to enclose said track and channel on said" side of the car; the parts of the gate v bein constructed and arranged so that the W ate- `rnpletely encloses the opening at the ront fof the cal"U when in closed position and, upon movement, follows the track and channel around the corner between the false panel and the sidesof the car.

In testimony whereof, I have signed name tothisspecification. THOMAS BRADY.
