vTILAVEL'ING HINGE.

Application filed .April 1.4, 1924. Serial No. 706,436.

To o7] whomy it may conce/"ii:

Re it known that I, .li-:ssn C. EAST, a. citizen of the United States, residing at Columbus, in the county of Muscogee and State of Georgia, have invented certain new and useful Improvements in 'ilraveliingl Hinges, of which the following is a specification.

This invention relates to traveling hinges,

and is designed primarily for use upon show` and display case doors and has for its primary object the provision, in a manner as hereinafter set forth, of a traveling hinge of a construction whereby a traveling swinging movement may be imparted to the door to which it is applied, to cause the door to move transversely of the face of the case and at. the same time to swing inwardly therefrom to assume an open position at right angles to the face of the case and at one side of the entrance thereto.

Another object of the invention is the provision, in a manner as hereinafter set forth, of ay traveling hinge having wheeled track guided supporting means as a part of its structure whereby an easier and smoother action may be obtained in shifting the door to which applied.

final object of the invention is the pro-y vision in a manner as hereinafter set forth, of a traveling hinge designed particularly for use upon showcase doors which will be of strong and durable construction, quiet and efficient in action, simple in construction, and inexpensive to manufacture andapply.

The invention will be. best understood from a consideration of the following detailed description taken in connection with the accompanying drawings foi-ming part o t this specification, with the understanding that the, invention vis not confined to any strict conformity with the showing of the drawings, but may be changed and modified so long as such changes and modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

'In the drawings: y

Figure 1 is a vert-ical sectional view of a case from the front to the rear thereof showing a door supported in open position upon a device of the character embodying this invention.

Figure 2 is a horizontal section taken u pon the line Q-Q of Figure 1,

Figure is a horizontal section taken upon the same liuc as Figure 2 but showing' the door of the case in closed position with the hinge structure at the front of the casing.

Figure 4 is an enlarged detail sectional view taken upon the line t-t of Figure l. Figure 5 is anV enlarged detail sectional view taken upon the line 5 5 of Figure 1. Figure 6 is an enlarged detail perspective view of the structure embodying this invention showing' a. portion of the door to which it is applied.

Referring now to the drawings in detail wherein like reference characters indicate corresponding parts throughout the several views shown in the dra-wings a portion of a showcase is shown having the usual top l, base 2, back 3 and floor 4. The side wall 5 may be the outside wall or it may be the dividing wall for a. double case. Along the. side wall 5, the Hoor t is stepped down toA forni the step 6 upon which the door carrying mechanism. is supported. The front of the case is open asat 7 and this opening is adapted to be closed by the door 8 as shown in Figure. Y

Running from the front to the rear of the case upon the step 6 and also upon the under side of the top l above the step are parallelV tracks l() of T-shaped cross section secured in position by the screws 11 which are passed through the cross heads of the members which form the flanges of the track. As will be clearly seen in vFigure 1 these tracks 10 are in superposed relation one to theother.

The door S'carries a pairof the hinges embodying this invention, one at the upper side and the other at the lower, these hinges being in superposcd relation, and except for the fact that the hinges are one upright and the other inverted,'they are exactly alike in structure and therefore the cli-iscript-ion of one only will be suflicient.

It is thought that a clearer understanding of the structure of the hinge vwillbe had if attention is given to Figure 6 of the drawings. The hinge comprises a` fiat substantially elongated plate member l2 secured by means yof bolts Aor screws 13 to the face of the door 8 adjacent the upper or lower edge thereof, depending, of course, upon whetherv the hinge is applied to the topy or the bottom f prises a substantially elongatedilat. central `plate portion l17 having each* end rolled as at 18'v to provide hinge knuckles adapted te be pivotally connected to corresponding hinge knuckles 19 and 291respecti=vely oft-he aforementioned leaf and afsecond leaf 21k connected to the other end of the y'il'at'e 17; V It will be noted that the pla-.te 1.7 overhangs the outer end of the plate 12 and also the side edge of the door. 8 to which the twoA plates are connected.. VTherefore the leaf 211 swings uponthe end of: the intermediate porv tioni17, clear of the door Si The Jxree enel of the outer hinge leaf 21 is bent at right angles tothe inner endx as at 22 soy that the inner. end/of the leaf 2l 'when the plate 17 is lying fia-t against the. plate-12,;is v at right angles 'tothe plate v17r andthe outer end 22 i 'is parallel with the. plate 17 and located at a; positionback ofitas isclearly apparent upon; reference yto.Figuresv2 andi 6. n The angled. extensionY 22. of the leaf 21 Vhas the outer free portion provided: with a Vseries of vvertically extending slotsY 23 the purpose of. which willfbecoine apparent, and the inner, portion has securedr` the-reto, a

.threaded lug 23a as shown.

@Located beneath! the Vplate 12 and the double hinge ineinber 1,6- is an Aangledr bar of substantial length, one end` ofl which: is

y positionedx beneath the plate and the-hinge referred to and the other end extending f outwardly beyond the free end oftthehinge 'adjacent the center thereof;

has its lnner-endspaced from theinner end This angledbarhas one flange 24, horizontally. positionedwith the outer face thereof; vopposing the underr sideof the doorI 8;,

`and the other; fiange 25v has itsouter face opposing the, side of the lowerI portion of the side wall 5 and. substantially parallel lwiththe inner' face ofthe door 8; when the doorAV is. inopenposition, aswillibeclear u] on.reference to F1gure4l ofthe drawings.

A'gheA horizontal.. portion 2.4 of' the angled bark has a pair ofE substantially elongated slots. formed therethrough and, longitudinallyv thereoflras lindicated at 26 i and 27 i ,respectirely, the slotA 2being-of slightly less width thanthe slot 27andextending from the outer; end Iof theangled bar to ai point The slot 27YV of the sloti 26 a-ndextends ytoapyoint adj acentt-lierear.,endlof thefangledibar;

Secured to the flange 24 of the angle iron -arethree angle brackets-28, 29iand V30, the Vanglebrackets 28 and 29Lbe1ngsup Vported attheouter end offtheangled bar,

the; bracket` 29=being located over; the slot 26- and thebracketi 2:8 v bei-ng extended through a: slot init-beside 25 and-shiiitabl-y secured I to y thel under side oftlre ,liange 2.4 of the angledbar, bolts 31 and-32grespee tively,v which passthrough ,theslo'tr26 l'secure the brackets .andere retained upon thema-g der yside by nuts 8?; and-34: `I

A nut 87 engages. the lower end ofthe bolt to securethe roller 36' in position in thev slot 27 and aO'ainst the under surfaceof the horizontal portion of the angle rEhe verticalV portion of the anglebracket 39 is countersunk inf the inner face of the door 8' and tl1e-plate 12 eX.- tends thereover and is secured thereto' by rivets 38 asis cleanly shown in Figure 45 of! A the-lower end of which engages in the lug 23lL to raise or lower the hinge,l and door to which it is connected; Alt inay be seen here that thefdoorinay be raised oli/lowered by loosenlng the screws 39: and moving the Y angle bracketY 29 to the desired position, byv

actuating the screw 29". This connection thro-ugh the 'angle' bracket 29,-V and. screw, andl thev roller: engaging inf the slot 27v is theonly connection between theV portionv of thewhinge secured. to the door and.' the angled; bar. Y

'libe verticaliportionwof the-angle bracket 28 has.- passed :therethrough-af shafti40- `This shaft Vis 'fixedy to the vertical portion of the bracket and carriesupon its extended end4 theV outer side of the vertical por-A tion` of 'the bracket aI roller 41, vwhich roller Y basan peripheral groove 42'thereinfadapted to ht over the 1verticaly portion i of? the track 10` toy ridel thereupon.v Y A, nut 43 engagesl theA free' end ofy the bolt 40 whichf forms a shaft forv the wheel :41 andzsecures the wheel in position.

Located atthel other: or. inner:z end. ofthe angled bar against the Yface off the vertical portion 25 is a second whee'lor roller 44 of smaller circumference than the. wheel 41 and: thisA wli-eel 44I is.v likewise peripherally grooved-as at 45 to'ride upon theftrack l() engaged by the-groove 42' ofthe other roller 41. shaft 46 extends throughthe `vertical portiony25 of the angled bar andfthrough the center of the wheel 44 to support vthe saine. Af. roller bearing 47 Lis -v locatedv withinl the hub ofv the wheel? and surrounds the shaft 4G. The roller bearing is held in position, and the Wheel is held upon the shaft 46 by means of a combined securing nut and gland element 48. This securing nieniber 48 comprises a head having an annular peripherally threaded flange 49 which engages in the hub of thewheel and the roller bearing 47 is located within the annular flange 49 and held in position on the shaft 46 thereby. The outer end of the member 48 has a concentric threaded passage therethrough for engagement with the end of the shaft 46 to retain the wheel 44 thereon. Although the same has not been shown in the drawings it is desired that the bearing structure shown in conjunction with the roller 44 be also incorporated in the rollerv 41, in order that the action of the device may be noiseless and easy.

A roller member is located upon the floor 4 adjacent the opening of the case and engages the inner face of the door 8 when the same is in closed position, as shown in Figure 3.

In action the swinging" means embodying this invention operates as follows: Referring to Figure 1 of the drawings, where the door is shown in open position, when it is desired to close the door 8 of the case, the same is moved toward the -front and at the same time swung across-the front of the case until the leading edge of the door abuts the jamb of the opening 7 upon the side of the case opposite the hinge. This causes the rollers 41 and 44 to move along the track 10. At the same time that this forward movement- ,is started the forward or preceding end of the doors is swung across'the front of the casethus causing' the roller 36 to advance in the slot'27 of the angled bar, at the same time the leaves 15 and 21 of the double hinge 16 begin to swing at their respective ends of the intermediate plate 17 and the rear end of the plate 12 moves away from the plate 17 and this action is continued until the roller 3G reaches the forwardend of the slot 27 whereupon the door 8 will be positioned across the front ofthe case and the central plate portion 17 of the double hinge 16 will assume a position across'theangle formed between the door and the side of the case as is clearly shown'in Figure 3'. In this position the plate 17 actsas a brace for the door 8 preventing it from being moved further. The roller 36 ofcourse reaches the end of the slot and'also prevents further swinging of the door. vWhen Ithis point is reached the roller 44 will have reached the forward end'of the track 10 as indicated and the opening 7 will then Y.
