SPECIFIYGATIONfor-ming part of Letters Patent No. 567,570, dated September 8, 1896.

Application filed February 23, 1894. Serial No. 501,291. (No model.)

.To all whom it may concern.-

Beit known that I, OLIVER TIFFANY SPRINGER, a citizen of the Dominion of Canada, residing at Burlington in the county of. Halton, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Sliding and Folding Doors, of

which the following is a specification.

I titions are required.

The invention consists in, first, a series of doors, frames, or panels hinged together on opposite sides. Eachonehas a pivot-pin in the center of the bottom portion which slides in a groove or track in the floor or frame. The top of each door is provided with a swivel-pin let into each. The lower part of each pin is round and the upper part flat-shaped, with a hole through each for a pin to carry two rollers for each door, and made to run on a horizontal track above the doors. One end of the track being movable allows the doors to be instantly'folded side by side out of the way. Side friction-rollers attached to the said pin remove side friction of the track. I attain these objects by mechanism illustrated in the accompanying drawings, in which Figure 1 is a side view of three doors and frame. Fig. 2 is a plan View of the top track. Fig. 3 is a plan of the bottom track. Fig. 4 is a top view of the doors without frame. Fig. 5 is a top viewshowing doors folded to one side. Fig. 6 is a perspective View of the top swivel-pin. Fig. 7 is a cross-section of bottom pivot-pin track and door. Fig. Sis a cross section of upper track with rollers, &c. Fig. 9 is a side view of movable section of track. Fig. 10 is a side view, detached, of one roller, pivot-pin, socket-plate, and track. Fig. 11 is a sliding block and fastening, beinga slight modification in lieu of the rollers.- Fig. 12 is a top view. Fig. 13 represents the end view of the sliding block. Fig. 14 is a side view of doors closed as a partition. Fig. 15 represents the, same folded back. I

A A A, Fig. 1, represent doors hinged together on each side alternately by hinges B- Each door has a plate 2, secured to the central bottom portion, having a circular opening through which is made to pass a round pin 0, having a flat head 3 above the plate 2.

The said pin slides in the groove D, which may be made in the floor or between the bottom rails D,oovered with metal strips f f, as shown at Fig. 3. The lower portion of the pin 0 may have a flange ordisk 4 attached thereto or the pin passed through it and a nut 5 screwed o'n the'threaded end of the pin C, as shown at Fig. 7, or riveted, allowing each pin 0 to slide horizontally with its door and prevent them from being raised out of place.

The device for hanging each door at the top may be described as follows: E is a swivel-pin, shown at Fig.6 detached;'andattached art-Fig.- 1, to the center top of each door, and made to pass through a metal plate F, havinga central boss 6 countersunk in the top of each door. The said swivel-pin is screw-threaded at the bottom and held in place by a-nut 7. Theupper end of the said pin has a hole athrough it to receive. a spindle b, which carriestwo rollers c c for each door. The said rollers run on the upper track H above the doors, and may be covered withrubber to prevent noise. 8 8

'are two projections'on the sides of the said swivel-pin for a bearing on the plate F, and

the flat portion. of the swivel-pin E slides in the, space d between the two portions of the track H. Two friction-rollers, w w are held in the swivel-pin E to prevent side friction whenthe'doors are opened or closed. 9 g are metal strips, screwed on the top of the upper track for the rollers c to run upon. his a cover 0 for the chamber '5 above the upper track to allow room for the rollers to operate. Aportion H of the top track H will be movable between the dotted lines o '0, Fig. 1, to allow the doors when pushed back to slide at or about right 9 5 angles to the main track to make the doorsflush with the frame A on either side, slots m being made on both sides of the bottom track to admit the pins 0 at the bottom of the doors to allow them to be placed in the position as Ico shown at Figs. 5 and-15, when they areout of the way.

Fig. 8 shows a section of one end of the movable portion H of the track to allow the doors 8 representing a metal plate, m-shaped fas tencd to the track on both sides, and t atop titio'n against which they abut.-

plate secured to the frame as most convenient. u u are two separate grooved plates into which the plate slides and carries the movable portion 11 of the track and doors to either side of the partition, as desired.

In operating the doors it will 'be seen that assuming them all closed, as in Fig. 1, in a straight line forming a partition, to open them they are pressed sidewise at their hinged portions, which causes them to fold together flat, when they may be moved to any desired side of a room, as seen at Fig. 15, the slots m m m (as many as are pinned doors) in the side extensions of the lower track and the movable portion of the top track between the dotted lines o r enabling the pin C at the bottom of each door to slide in the said-slotsm, and make the. edges of the doors flush with the frame A on one side, as in many cases so desired to be out of the way in-one portion of a room, or as in front of a stage, &c. otherwise the slots m may not be neededi,.and' thedoors will fold in: the center of the frame or in arecessin a par-- To close the doors, they are moved out to the line of partition and-closed together. To make I tight joints on their edges for a tight partition,

each door will be alternately tongued and. grooved, which fillsup the space between the doors. v

V The doors can bemadeof woman any man ner with paneling, &c., orframes with glass,

as desired. 7

I have shown the doors operated on a double track, but do not confine myself to that construction, as they eouldbe operated on a single track by ommitting one of the rollers 0 over each door and using the-same pinsor slightly altering them to'suit the requirements, but. I prefer two rollers c cto each swivel-pin, as balancing the doors more effectually. I

It 'willSb'e observed that ifa recess is made in the wall or partition againstu'which the.

the doors capable-of being moved'along the I track by means of the swivel-pins and rollers, but the rollers could be replaced by a doublegrooved slide block 1') and made to slide upon corresponding projections on the track, as

shown-atFigs. 11, 12, and 13, the latter being an end view. The upper end of the pin E in this case would be screw-threaded, upon which, after passing through the slide block 19, would be screwed a pronged nut q, having two vertical projections 1' r, and held from turningby means of a split pin 0, passing through a hole'in the swivel-pin E and the ends of the splitpin pressing on opposite sides of the prongs 'r The said swivel-pin in this case would be attached to the plate F, V

.secured to the top of' each door- 1 1 p Itwill be understood that {thesaid-apparatus' is capable of modification-in various ways other than described. 'lhe'm'odified,ra ,rangement, as shown in Figs. 11, 12, and 13, iwhich correspond to Figs '8 and 10', does'not Ition, about "eighteen inches of track only may be laid, and'bolts may be used at the bottom of the othe'r doorsto render them rigid when drawn out, and one door may be left free, as

in..Fig. 14, without attachment at either botgtom lor' top, and beoperated as an ordinary doo I Having thus described my invention, what l'claim, and desire to secure by Letters Patent, is- I The combination with the sliding 1 doors A,

of the upper track H suitable means for I hanging and guiding the doors thereon, the lower track D having the longitudinal groove D, the lateral groovesm communicating thereiwith, the guide-pins. 0 operating therein, the

Iconstruction and arrangementzbeing such that the doors A may be moved out of: the

lway-after having been slid to one side, substantiallyasand for the purpose setforth. Dated. at Hamilton, Ontario, Canada, this 323d day of January, 1894:.
