SLIDING DOOR.

Application filed July 28, 1923. 4Serial No. 654,502.

To all whom t may concern.'

Be it known that we, HERMAN N. MAY

and ERNEST M. MAY, citizens of the United` States, residing at Mineral Point, in the county of Iowa and State of Wisconsin, have invented certain new and useful Improvements in Sliding Doors, of which the following is a specification. f

Our invention` relates to sliding doors, of the type which are shifted laterally into the door opening, when brought into proximity thereto.

An important object of the invention is to provide a door of the above mentioned character, which is particularly well adapted for use in connection with barns, garages, and other buildings, kalthough the same may be used upon railway cars, or in any other desired place. s

A further object of the invention is to provide means whereby the door may be opened from either side, and when shifted laterally to the outer position, will be properly guided in its longitudinal travel, retained in close relation to the exterior of the building, or the like. A Y

A further object of the invention is to provide means of the above mentioned character, preventing chafing of the door, and eliminating guides or all attachments at the base of the door. e

A further object of the invention is to provide means for shifting the door laterally into and out o f the door opening, and for locking the same in the closed position.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification, and in which like numerals are employedA to designate like parts'throughout the same,

Figure 1 is an outer side elevation of a door embodying our invention, showing the same in the closed position,

Figure 2 is a transverse sectional view' taken on line 2 2 of Figure- 1,

Figure 3 Vis an inner side elevation of the door, showing the same. shifted laterally tothe open position, I

Figure 4c is a transversesection taken on line 4 4 of Figure 3, i

Figure 5 is a perspective view of the shift'- ing and locking means,

' formed therein.

Figure 6 is a transverse sectional view through the angle bar or guide element, showing it in the upper position,

Figure 7 is a similar View showing the same in the lowered position, and,

Figure is a horizontal section on line 8-8 of Figure 3.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of our invention, the numeral 10 designates a' wall, having a door opening 1'1 This wall may be regarded as a portion of a barn, garage, or car body.

The numeral 12 designates a sliding door, adapted to be shifted in front' of the door opening, in registration therewith, and then shifted laterally to enter the door opening, and to fit snugly therein. The door 12 is provided with recesses 13, upon its outer face, for the reception of brackets 14E secured therein by bolts 13', secured to the PATENT OFFICE.

door and `passing through openings in the brackets 14. These brackets receive between them the lateral ends 15 of suspension arms 16. The lateral ends are pivotally connected with the brackets, as are shown at 17. The

`suspension arms 16I are provided at their upper ends with lateral extensions 18, pivv `track or guide-way 23. This enclosed traclf` is bolted or otherwise rigidly secured to the walll 10, above and "adjacent to the door opening, as shown. From the foregoing description, it will be seen that the door mayl lbe shifted laterally into the door opening 11, Figure 2, or it may be shifted outwardly, and will hang substantially perpendicular as indicated in4 Figure 4c, whereby it will slide longitudinally in close'relation to the wall 10. f

Means are provided for effecting Athe y lateral movement of the door, embodying an angle iron or bar24.; The barv 24 is L-shaped in cross-section `and `is horizontallyfarranged upon the inner side of thedoor. Atits ends, Figure 5, the angle iron 24'has pivot elements or shafts 26 and 27 rigidly attached thereto, at Vits turningedge.

This edge of the angle iron. is secured'to- 'the inner side of the door by means of a.

hinge 28 or the like; It is thus seen that the elements 26 and 27 serve as pivotal supporting means for the angle iron, and that this angle iron also serves to cause these pivot elements to turn in unison. The angle iron also serves as a wear strip in the longitudinal travel of the door. The shaft 26 is pivotally mounted within a bearing 29,

formed upon a plate 30, which is bolted to,

the inner side of the door. The shaft 26 is continued beyond this bearing in the form of a laterally extending crank 31, provided with a curved portion 32 having an extension 33, arranged at a right angle thereto, carrying a roller 34, for a purpose to bedescribed. The shaft 27 is pivotally mounted within a bearing 35, formed upon a p-late 36, which is bolted to the inner side of the door. This plate carries an upstanding portion 37, as sho-wn. The sha-ft 27 is continued beyond the bearing 35 in the form of a crank 38, having a curved portion or neck 39, carrying an extension 40, at a right angle thereto, upon which is rotatably mounted avroller 41. The cranks 31 and 38 project outwardly beyond thel door through vertical slots 42 and 43, andthe y inner sides `of these slots are covered by guard plates 44 and 45, as shown. The roller 34 is adapted to engage within a bracket 46, the upper end of which is open and which is provided in its bottom with a cylindrical portion 47, for rotatably receiving the roller. The bracket 46 is carried by a plate 48, bolted or otherwise rigidly secured to the door j amb, at the right end of the door opening. The roller-41 is adapted to enter a bracket 49, having cylindrical portions and 51, for freely receiving the roller. The walls of the bracket 49 are spaced apart sufficiently to allow the roller 41 to pass from the portion 51 to the portion 50. This bracket is carried by a plate 51, bolted or otherwise rigidly secured to the left door jamb, Figure 1. -The bracket 49 also carries a resilient guard 52, curved outwardly slightly, to engage with the roller 4l and shift the same inwardly, into the bracket 49, when the door is shifted to the closed position, Figure 1.

`reason one lever may be passed between a pair 'of brackets 57, apertured for receiving the hasp of a pad lock or the like.

The plate 48, to the right, is provided `with a guide bracket58, which is in aline* ment with the angle bar 24, ywhen it is swung downwardly, Figure/r', andthe door shifted outwardly, Figure 4. Uponthe longitudinal movement of the door, the then vertical web of the angle iron will slide into the guide bracket 58, and hence the door will be retained in close relation to the wall. If desired, any suitable number of brackets 58 might be arranged in horizontal alinement along the exterior of the wall, to receivethe angle iron.v

The operation of the apparatus is vas follows: n I

l/Vhen the exterior handley 56 is in the raised position, the rollers 34 and 41 are in the elevated position, and the cranks 31 and 38 are raised, Figure 4. These cranks have forced the door outwardly, to the position shown in Figure; 4, and the do-or may now slide longitudinally. The curved ends As the door is shifted 58. The door may be shifted longitudi- It is to be understood that the form of our invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, Y size, and arrangement of parts may be res sorted to without departing from the spirit of our invention, or the scope of the sub joined claims.
