1 Claims. (01.- 126 5194) Thepresent improved invention has been conceived to provide a greatly improved hinge construction'which is particularly adapted for the oven or broiler doors of a cooking range, but as will appear from the following description its construction is such as to make it adaptable for doors used in many and varied capacities.

To'those skilled in this art it is well known that oven hinges as ordinarily constructed are in the formof castings which are as a consequence sub- Ject to frequent breakage and which due to breakage both at the time of fabrication of the range andwhenin .use, constitute a formidable item in the manufacturing and maintenance cost of cocking ranges.

As a consequence one of the primary objects of the present invention is to provide a hinge the parts of which are sheet steelstampings and which as a consequence reduce to the minimum the breakage in the manufacture of the hinge parts; breakage at the time of the fabrication of the range and the assembly 'of the hinge and range doors, and which are much more durable as-to life in the hands of the range operators.

Hinges constructed of sheet metal or steel stamplngs have the further attribute that if for any reason they become bent ordistorted they can be straightened by an ordinary mechanicwhich will thus avoid the heretofore andusual necessity of furnishing new parts brought about by the fact that the stress orstrain which has caused the bending of the stampings would have resulted in the breakage of the ordinary cast metal I hinge parts.

Another and further object of the invention consists in so constructing the hinge as to make it possible for the door to be" easily, quickly and readily attached and detached fromthe hinge and to accomplish this without in any manner disturbing or removing the hinge parts. Additionally the construction is such that the removal and attachment of the door can be accomplished by an ordinary mechanic or even by those persons who ordinarily operate and .use ranges.

A still further object of the invention is the of attaching the hinge parts to the door frame and of providing supporting bearings for the door.

An additional object-is that of prov ng anovel manner of attachment of the resilient means of the hinge.

A still further object of the invention is the provision of a novel manner of providing and securing pivot pins or pintles to the door.

Another and further. object is that of providingprovision of a hinge construction whichis com- 10" paratively cheap and simple of manufacture and assembly and which is highly efllcient and durable in use.

Other objects, ovel features of constructionand improved results of the invention will appear in more detail from the following description when read in the light of the disclosure of the accom panying drawings. 1

Having reference now to the drawlngs'which.

illustrate a preferred embodiment of the invention, I designates what is commonly referred to than in being provided with 2 s as the front frame ofna range 'andniay serve to frame one or more door openings. 'In the following description reference will be made to only a single opening as a door and hinge for a second or other door opening of the range would be of i like or identical construction.

The range front frame I illustrated is of ordinary or typical construction in most respects other elongated and verti- -cally extending slotsv 40 positioned adjacent the qppositelower corners of the frame dooropening. In conformity with usual practice the frame is ofa U-shape in cross section and has an inwardly extending outer marginal flange a and an inward- 15 lyextending circumferential flange b about-the door opening.

The door in many respects is of conventional construction and particularly so in that it comprises an outer front panel 2 which telescopically 20 receives an inner lining 3 to form a door-of hollow construction. The present/hinge is of the resilient type and includesa pair of coil springs of identical nature only one of which is illustrated and is designated 5 as an entirety by A and will detail hereinafter.

The links or connecting means between the springs or resilient means A and the door are designated as an entirety by the numeral 5 and as they are of identical construction only one of-them is illustrated.

There are a pair of bearings for rotatably supporting the door and these are formed as a part of apair of plates 24 of identical construction, only one. of which is illustrated, and will be later more specifically described.

, Referring now to the door Fig. 6 of the drawings, it will be seen that within the space between its panels 2 and 3 there is provided a bracket which is of an L-shape in cross section and. comprises the legs 8 and 8'. Theleg 8 abuts and is suitably secured to the door lining while and particularly to and separated relationship to thevertical end or side wall 9 of the door. This bracket is also clearly illustrated in Fig. 9 of the drawings and can be, if desired, of a length substantially equal to the height of the door or shorter as may be desired. In spaced aligned relationship this carries an outwardly extending hinge which are pggovidedwith respectively. Thiil shaft portions of the-.studs, Figr-12 of the drawings,

I are threaded as at and are. surrounded'by a ent within the opposite lower corner of the door.

spacer sleeve l2. The pins and stud are clamped in the bracket by tightening .down l3. J

suitable nuts It will be understood that a construction identical to that immediately before describedis pres- The door linings adjacent the leg portions 8' of the brackets are provided with an opening 42 the purpose 'of which is to permit the passage of the door bearings, appear.

Describing now in detail the plates or members 24 which are of a stamped steel form or construction,"it will be seen that the plates are of an- 'L -shapein cross sectioncomprising the legs 25 and 26 disposed at right angles to one another.

In the assemblyof the spring, see Figs. 1 and 6 of the drawings, it will be seen that the leg 25 oi'--the plate abuts the inner face of the.front opening 21 which fora considerable length so as to form no ob- 'struction to the be described in more it the leg 8 extends outwardly -therefrom towards the front panel 2 in spaced as will hereinafter more fully end an open bearing or pocket 23 which is of hook-like form. It will be seen by reference to Fig. 6 of the drawings that this ear extends outwardly through .the slot 40 of the front frame I and is disposed exteriorly of the front frame and at right angles to the outer face thereof. Each plate 24 reduces the width of the leg 25 upper portion of the frame slots 40; The lower portion or wall of the cut-out or opening 21 is designated as 34 and acts as a stop, as will hereinafter more fully appear.

Above the opening or cut-outs 21 the plates are provided with an inwardly extending tongue 32 which is preferably obtained by cutting the leg 25 .and bending the portion of the leg which lies within the cuts downwardly and inwardly. Above the tongue each of the plates is provided with an opening 43 through which passes a bolt 3|, the head of which is at the outer side of the front frame I. This bolt will serve to correctly position the plate preparatory to its being welded to'the front frame and serves also to lock the clamp plate 29 to the plate.

Q The clamp. plate is inthe form of an open sided box having an opening 44 for the passage of the bolt3i .and an opening 33 for the passage of the tongue 32. The bolt 3| and the tongue 32 are in alignment and in spaced relationship to the side wall d ofthe plate.

is provided with a cut-out or spring A secured to each It will be seen that these springs comprise a convolute 4 from which extends at substantially Jright angles to the horizontal axes ofthe convolute an arm or end portion 28 which is disposed within' the clamp plate or ,box 29 in the space between the side wall d thereof and the adjacent sides of the bolt 3| and the tongue 32.

The extreme end of the portion 28 of the spring is bent at substantially right angles as indicated at to lie behind or beneath the tongue 32. It will thus be seen that when the bolt 3| is tightened down the spring is securely locked to the plate 24 against possible displacement and against rocking.

The other and 'freeend l6 of the spring is of considerable length and when the door' is in a closed position, see

and inwardly at The lowermost end of this arm Fig. -3, extends .downwardly l6 of the spring passes through an opening IS in the head or cross v .arm portion I! of the link 5. In

Fig. 10 of the drawings the method of securing this end with the opening I! is clearly illustrated.

The links 5 pass loosely through the openings 21' of the plates 24 and the openings 40 in the as the openings 42 in the front frame as well I 3 of the door. As clearly illustrated in the drawings the hooked ends of the links .tively engage the studs or; pins Because-of the aforementioned looseness there would be a tendency for the links to tip laterally under the action of the coil springs and to prevent such tipping .or turning of the links sheet metal members 20 are provided which are applied to the spring opera an angle to the front frame.

'- passes through operation it will be arms [6 in the manner Illustrated in the drawings. These members upon the spring arms in'that the spring arm the openings 2| and 22 thereof. The'upper end of each member right angles as indicated at 2| and a portion 01' the opening 2| is through this ear 2|. In. seen that the members 20 provide a continuous bearing surface which will engage either the heads or cross arms ll of the links or the main arm portions 5 thereof and serve as an abutment to prevent the links from pp g.

When the door is swung into a completely open position as illustrated in dotted lines in Fig. 3 of the drawings, the lower walls 34 of the openings 21 of the plates 24 act as stops and supporting means for the door in that they engage the lower edge of the links at apoint adjacent their connection with the cross arms or heads ll of the links. The forward edge orshoulder e of the link cross arm l1 above the main arm 5 of the link will engage the innerface of the plate and serve as a stop to the outward movement of the door.

In the construction the inner door panel 3 is removably secured to the outer .paneland inasmuch as these panels are subjected. to considerable stress and strain the attaching means prothe four corners of vided is such as to strengthen and give rigidity to the door. By reference particularly to Figs. 4, 6 and 11 of the drawings it will be seen that at each of its corners the inner face of the outer door panel 2 is provided with a U-shaped housing 31 the legs 46 of which are suitably welded to the front panel. The bridge or top of the bridges or tops of these housings are provided with a threaded opening 35 which threadedly' receives the shanks of suitable bolts 3' which bolts pass through the openings 35 which are disposed in the door lining panel 3. Irrespective of whether the door is in an open or a closed position the springs are constantly exerting an inward pull upon the links 5. This tension will maintain the pintles I0 within the bearing pockets 23 of the bearing 6 and will of course at all times maintain engagement between the hooked outer ends 5 of the links and the link studs or pins ll.

The tension of the spring and the arrangement of parts is such that when the door is swung into a completely open or horizontal position it will remain or stay in that position until it has been manually raised past a dead center point.

For the accomplishment of the easy, quick and almost instantaneous removal of the doors and of the links 5 intermediate its length is provided with an opening 51 into which is adapted to be inserted a pin 38 or "the like. These pins are inserted through the opening when the door has been moved outwardly to the position indicated in full lines in Fig. 5

of the drawings and bear against the outer front face of the .frame I and thus lock the links 5 against inward, pull of the'coil springs. With these pins engaging the frame I the tension of the springs upon the door pintles ,and studs Hi and I2 is relieved and the door can be readily detached and removed in the manner illustrated in dotted lines'of Fig. f the drawings.

This removal is accomplished by swinging the lower 'end of the door outwardly .and'then moving the door inwardly and downwardly. To replace the door it is necessary only to reestablish operative connection between the pintles l0 and the are 'in reality threaded 20 is bent at 3 bearings 5 and the pins II and the book ends of the links 5 and then exert an outward'movement upon the door and thereupon remove the pins 38.

From the foregoing it will be seen that an arrangement which is comparativelyv cheap and simple of construction has been provided for accomplishing the numerous objects. and desirable results heretofore enumerated and that the resultant structure is one which is highly efiicient and durable in operation.
