g/WM Patented Apr. 5, 1932 HUGH n. GRAIBLE; or CANTON, onto SLIDING AND SWING'ING DOOR Application filed January. 24, 1930; Seria1No'.423,'-152:

The. invention relates-to elevator doors and more particularly to. doors havingv a combined sliding andswinging movement- Elevator doors, such as are used in apartz;;ments andsimilarplaces, ordinarily comprise one. ormore slidable sections andone stationarysection behind which the slidable sections are adapted to move in order to give access tothe elevator car. The width'of open- 103 ing thus obtained is less than the width ofthe elevator car owing to the stationary door section which covers a portion of the car.

It is frequently. desirable to have adoor opening substantially equal to the width oftheelevator car inorder to carry furniture OITrOtheI, freight inthe car, and the object of thepresent improvement is to provide a door composed of combined sliding and swinging,

sections so arranged that the front f the g slidingidoorsections will hang. onheavy iron clips or brackets, indicated at 23 on the drawings, which are secured. to the sliding bars 19,

and. engaged by thelocking members 34 carried .inthe: front edges of the sliding door sections and adapted to be released to permit the slidingdoor sections to-swing outward to a right angle position, Otheruobjeots of the improvement are to provide means. for supporting the door secaogtions againstsagging when swung into the fully opened position; and to generally improve and-simplify structures of this nature.

embodiment of the invention is illustrated in the accompanying drawings, in 35rWhlCl'L Figure 1 is a .plan View of a combined slidingand swinging'door taken from the inside of the elevator car;

The sill 10 may be mounted in the-floor at* each door opening of the elevator-shaft and is preferably in the form of aheavycasting 1; as illustrated; ancltheupright frame memhers 11 preferably of sheet metal, andof *anyusual and well" known construction, are mounted at opposite sides 0f the door open- 111g!v c Thedoor maybe made up of any desired number ofsections and for thepurpose of illustration is shown as comprising the normally stationary r section 12, adapted for swinging movement only, and the normally 5 t 1 slidable sections 13 adapted for both slidingfrom the slidin'gba rslS) suspended as by the bolts 20 from the usuail'sliding dooahmg ie (not shown) which may be ofany'iisu'al and well known -construction l and which may be normally covered bya hanger 'cover 21 ofanyi desired form. r

Each of the door sections 13 is pivoted near its outermost edge to the corresponding bar 19 as by a stud or screw 22 and is normally held against movement with reference to the bar 19 by means of mechanism engaging its opposite edge portion, as best shown in Fig. 6.

For this purpose a U-shape or channel bracket 23 may be carried by the adjacent end portion of the bar 19, the lower inturned leg 24 thereof being adapted to be received in a groove 25 formed through the inner side of the door section.

A latching bolt 26 is slidably carried in a bracket 27 fixed upon the interior of the door section and a coil spring 28 is located around the bolt and interposed between the lower arm of the bracket and the collar 29 upon the bolt, tending to normally urge the bolt upward and into the aperture 30 in the arm 24 of the bracket 23, in the position shown in Fig. 6, latching the door section against movement relative to the corresponding bar 19 which supports the same.

For the purpose of manually operating the bolt 26 to withdraw the same from engagement with the bracket 23, when it is desired to swing the door section outward, an opening 31 is formed in the edge wall of the door section to permit the finger to be inserted therethrough to engage the pull handle 32 fixed upon the lower end of the bolt as by the rivet 33 or thelike.

As best shown in Figs. 6 and 7, the bracket 27, carrying the latching bolt, may be fixed upon a separate plate 34, in which the finger aperture 31 is formed, this plate being connected to the edge portion of the door section as by screws 35 or the like.

At the bottom of each of the sliding door sections 13, andin alinement with the upper pivot stud 22, is located a depending pivot pin 36 arranged to slide in the longitudinal parallel grooves 37 formed in the sill.

A channel supporting and guiding bracket 38 is connected to the bottom edge of the door section 12 and a similar bracket is connected to the bottom of the central door section 13, these channels slidably receiving the depending flanges 39 upon the corresponding door sections 13 and being adapted to guide and support the several door sections in the sliding and swinging movement there of.

As shown in Figs. 1 and 2, when the door is closed, the door section 12 remains in the normal position and the sections 13 are moved into position to close the normal door opening, slightly overlapping each other and the section 12 in the customary manner.

The doors are slidably opened by any usual and well known mechanism, such as is at present in common use, the sections 13 being slidably-moved one behind the other and both behind the section 12, as shown in Figs. 3 and 5.

When it is desired to swing the door sections into fully opened position, the bolt 18 upon the door section 12 and the bolts 26 upon the door sections 13 are all released, permitting the section 12 to swing outward upon its pivots 14 and 16 and the sections 13 to swing upon their pivots 22 and 36 into the position shown in Fig. 4, the guide and support brackets 38 properly guiding the door sections as they swing to this position and permitting the lower pivots 36 of the sections 13 to assume the proper positions in the grooves 37 of the sill.

With the door sections in the positions shown in Fig. 4, it will be seen that substantially the entire door opening is avaliable for passing furniture or other large objects through the same.

hen it is desired to again move the door sections into position for sliding movement, it is only necessary to swing the sections upon their pivots back to the position shown in Figs. 3 and 5 and again lock them by means of the bolts 18 and 26 so that the section 12 will be held against movement and the sections 13 will slidably move relative to each other and the section 12 as in ordinary practice.

From the above it will be obvious that the door sections may be easily and readily swung into the fully opened position and again moved back into the normal position with a minimum of time and efi'ort, it being only necessary to operate the bolts 18 and 26 in order that the door sections may be released or locked.
