of a building. In this building there is ad rway 2, which is to be closed by means ofla verti-' I cal door which is adapted to be; moved upwardly and toassume a horizontal position zabove; the

doorway duringthe time that the doorway is being used. 1

In this operation of the door the door is supported on eachfside .bymeans ofa guide memberaThe vertical part of thisgui'delrnember is indicated by the-numeral. 3, the curved part by the numeral" 4 and the horizontal overhead a0 partby the numeral 5,. All of these parts 'tosether constitute a", single guide memberfforming a continuous runway in which the rollers move. rjtAttached to the wall of the buildingad- Jacent the, DPe r side o'f] the doorwayfis [a a6- bracket fi. Therefisone of these bracketson each side of thedoo'r, and it is attached to the wall by any suitable means. 7 At. the lower .end of the bracket there" is a downwardly inclined slot 7 which terminates in a 'substantially'verticalpocket 7a. .The-door used for closing-the doorwayis formed-01a largenumber of panels 8. In the present instance there are fouro'f thesepanels shown, one pivotedto' the otherjto form, the 96 complete door. .These panels'areconnectedto one anotherby means ofliingesjQJv Oneach side of the upper section or panel there. is atmay beattached tothe door by means of bolts 100 or screws. Extending from the lower end of the bracket is an arm .11 which has on the outer end thereof a. roller 12 for engagementwith the lowerpartof the bracket 6 wlthin the :slot Tand seat 7a when the door is. being closed andis closed. i A the door panel, showing tbe bracket shown in On the upper end of the bracket thereis pivotally mounted an arm 13L This arm is pivoted to the bracket 10 at one fend has on erated mechanism for assisting in opening the door;

'14 fits and moves along the guide members in the process of opening and closing the door.

Extending from each of the hinges 9 is an extension shaft 15, which has on the outer end thereof a roller 16 which is located within the .guide member for the'purpose of supportingthe door and its panels, and for the purpose of guiding the parts of the door during the process of opening and closing. When the door is closed these rollers are in the vertical part of the guide member. As the door is opened they shift from one part of the guide member to another "until they finally assume positions in the horizontal part of theguide member. In this position the door is fully open and supported overhead. 1

For the purpose of assistingin opening and closing the door there is provided a spring 17, as indicated in Figure 1. This spring, whichserves as a counterweight, is attached at one end 18 to a suitable part of the wall Just above the doorway and to one side thereof. At the other end of the spring are" two pulleys'19. Ad-

jacent the point .18 where the spring is attached to the wall there is located on the wall a pulley 19a. On the wall across the doorway from the pulley l9 are two pulleys, 20 and 21, located and supported on a plate 23"suitably attached'to some part' of the wallor to one of the bracket members 6. V I

Attached to the lower end at one side of 'the door is a cable. or rope 22. This cable extends upwardly from the righthand lower corner of the door, as shown in Figure 1, over pulley 20 and around one of the pulleys 19 to a screw eye 21a, by which it is adjustably attached to the wall adjacent the pulleys 20'and 21. Attached to the lower lefthand corner of the door is one end of a second rope or cable 22o, which "passes up over pulley 19a, around pulley 21 and around the other pulley 19 to a screw eye 20a, by which the other'end of the rope or'cable is adjustably attached to the wall adjacent the pulleys 20 and 21. The tension of the spring tends to draw the door up'and assist in opening it. -When the door is fully opened the pulleys 19' are nearer to the pulley 19a than they are as'shown in Figure 1. By this arrangement of pulleys, springs and rope there is provided a compact, conveniently located counterbalance spring op- In orderto facilitate the movement ofthe door and provide means for grasping'it'by the hand there is a loop 24. There may be as many of these loops as are necessary. This loop may 'be used for both opening andclosing the door.

In order to further assistin opening-thedoor there may be provided a tread member 25 lofcated on the extreme lower edge of thedoor.

For the purpose of securing the door in locked position there is provided, as shown inFi gure 1,

a lock 26. This lock is placed on one side 'of one of the panels and has a plunger adapted to fit through a hole in the wall of one of the guide members. While there is only onelock member shown there may be. any number used. A chain 27 is used for raising and loweringthe door.

Each hinge 9 is composedof two leaves 28 and 29. Each leaf '28 has on one end thereof a pair of spaced ears 30, while each leaf 29 has on one end thereof a pair of ears 31. Each of these ears has a hole extending therethrough in which the shaft 15 fits. 'This shaft operates to hold the leaves together to form a complete hinge. In order to prevent longitudinal m0ve-.

hinge is constructed and operates alike so the following description, while it applies to one particular'hinge, applies equally to all the hinges :used in connection with this door.

. On the reduced part of the shaft 15 is a bearing ring 34. This bearing ring is mounted upon the part 33 so that it may or may not rotate therewith but will have a sliding movement along the reduced part. on the outer end of the shaft is a pin 36, which prevents the bearing ring 34 from running off the shaft. This bearing ring 34 has a'raceway therein. I I

The roller'16 has in the center thereof a relatively large: opening w-hich has a flange 3'7 at one side of theroller. "and abutting against thesifiangeis an annular bearing ring 38, which cooperates with the Within this opening bearing ring 34 to form a'ball race in, which balls 39 are located for anti friction purposes. In 'order to hold the bearing ring 38 properly positioned in relation to the roller 16there is 'providedan annular plate-.40, which fits in Ia recess in "one sidef'ofthe roller and. engages both of thebearing rings so that they are firmly held in position with relation toeach other, and

with relation to the bodyof the roller. By this -means 'the roller may easily rotate around the shaft and the bearing ring .34; and move longi- 'tudinally of the shaft .;with thev bearing ring 34 but cannot move longitudinallyof theshaft without the bearing .ring 38. By this: means there is permitted a slight, sidewise movement of the door or one: part of the doorwith respect to another part withoutjamming, or pinching. This free-movement .of the, roller on the shaft also permits a slight variation-in the guide member without pinching orbinding. 1 7

For the. purpose of strengthening the door and preventing its sagging, as when in an overhead, suspended condition; there is provided a transverse reenforcing bar 41. This bar is U- shaped -and is attached ateach end by means of eye members to the lower leaves of the hinges, or to other suitable plate members. One eye member-42 is permanently anchored to one side of the door to either a lower leaf of a hinge or to a'separate plate membensuch as that shown in the lower righthand corner ofthe door. This eye member is attached to the door by means of bolts and nuts 43.1 In. one end of the'eye member is a suitable hole oropening.

'- For the purpose of. uniting one end of the reenforcing bar to the eye memberthere is a hole through ,the. sidewalls of the transverse supporting bar inline with. theholes. in the eye member. .The, edges of, these holes are bent in, as indicated by,the numeral 44, and closely grip around the inside ofth'hole'infthe eye and form for the eye a bearing closely fitting and almost entirely surrounding the inner surface of the eye.

In order'to securely hold these parts in the position shown in Figure 10 a suitable bolt 45- is provided. This bolt' has-the usual head and nut. Adjacent the head andth'e nut are washers 46, the cooperatingfacesof which are conical in shape and adapted'to closely engage. the

turned-in parts of the transverse bar around the holes therein so that thoughpressure be aptermediate hinge,

plied to the eye members the walls around the holes in the sides of the U-shaped transverse reenforcing member will not be straightened out but will be firml'yheld in position,fowing' to the peculiar shape of the washers. Each end of the transverse reenforcing bar is provided with a similar means by which the 'eye members are attached thereto. However, the eye member on the lefthand side of the door, as shown in Figure 3, instead of being anchored or fastened permanently to the edge of. the door isfastened to a plate or hinge member by means of a screw and nut member 47. By this means the reenforcing bar may be tightened and hcld firmly against the door to prevent the sagging thereof. In Figures .3 and 10 the eye members are shown attached to plates located in the lower corners of the door. Plate 48, sh'own in Figure 10, is located in the lower righthand corner of the door, whileplate 49 is attached to the. lower lefthand corner of the door. These 'plates'in the present locations take the place ofthe lower leaves of the hinges for supporting. the eye members, because in the present location there'are no hinges. From these plates also extend shafts 15, which have on the ends thereof the rollers 16, such as shown in Figure 11. In all places except the ends of the door the transverse reenforcing bar is attached at. each end to the lower leaf of a hinge, as clearly shown ih Figure 1; V In order to support the intermediate part of the transverse reenforcing bar there is "provided at each end of the door a U-shaped bracket member 50. This member its over the intermediate part of the bar and prevents its sagging, and also holds it in close contact with the door. The other transverse reenforcing members are supported intermediate their ends by U-shaped loops 51in the lower leaf of an'in- There is also. provided a bracketmember 52 attached to the door intermediate the ends of the reenforcing bar for projecting into the channel part of the U-shaped member. This internal bracket 52 may be used alone or it may be used in connection 'withthe brackets 50 and the loops 51 of the hinges. v bracket within the U-shaped transverse bar tends to preserve the shape of the transverse bar and prevent any wobbling or unnecessary vibration thereof.

In the position shown in Figure 1 the door is in a closedcondition. In order to .open the door the hand loop 24 is seized, the door is lifted up and caused to follow the guide or trackway 5. In this operation the operator isassisted by means of the spring 1'7, which tends to elevate the door. After the door has assumed a horizontal position, the transverse reenforcing bars prevent the central part of the door from sagging. In case the transverse bars should become loose they may be tightened by means of the nuts 4'7 on the ends of the adjustable eyes, and in order to facilitate and make easy the operation of the door and to diminish the tendency to pinch or bind, the rollers on the ends:v

of the shaft are loosely mounted so that there may be a certain amount of lateral movement of the rollers in relation to the door.

I All of the parts of this door are separate and distinct from the others and may be easily replaced when they become worn or broken.
