7 claims. (01. 15 -179 This invention relates to an improved xooncealed hinge whose sides are riveted or otherwise attached between the sides of the frame of the modern automobile and other vehicles using hinges for doors and may readily be adopted for general use.

This invention seeks, among other objects, to provide a hinge which may be readily fashioned from suitable sheet of metal which as compared with other hinges as heretofore constructed will be stronger, more durable and possess superior mechanical features suitable for the modern automobile or other vehicles.

This invention seeks, as a further object, to

provide a hinge wherein the sides of the fixed hinge member will be sturdily held against spreading, as the side walls of the hinge-box is provided with holes for the purpose of riveting said sides to the door or door frame of the vehicle, so that undue looseness is prevented. It-is another object of thisinvention to eliminate the rattling of the door ofautomobiles or other vehicles while they are in motion. One further object of this invention is to pro vide a hinge wherein the movable hinge member thereof may, when desired, be readily disengaged from the fixed hinge member, *permitting {the simple displacement of the door with the greatest facility. a

Another object of this invention is to provide a hinge whose movable member, when having a guide inserted into a slot located on the lower wall of the box of the fixed hinge member, serves as a strap, for checking the opening "of a door and limiting the outward movement of the door on its hinges.

This invention seeks as another veryimportant object, to be suitable for either straight line or curved line doors, While the width of the fixed hinge member remains the same.

Other objects and features will become "apparent from reading the following detailed description of the embodiment of'the present invention. Y 7

The invention generally consists in the features of novelty appearing in the construction,- arrangement and cooperation of the several parts hereinafter fully described, and is taken in con-' nection with the accompanying drawing, in

Referring now to the drawing in which-referencecharacters designate like parts throughout, a frame section A of an automobile or other vehicle is recessed to accommodate the non-movable portion C" of the device as shown in Figs. .1 and 2. Said portion C is made of any suitable material and is preferably of rectangular shape with a front and two opposed side walls as shown. The walls of said portions are provided with a plurality of openings I0 and l l for, accommodating screw members, not shown, forv fixing the portion C to frame section A. Said portion is also provided with a pair of spaced, parallel, horizontal plates fixed to the vertical walls as shown in Fig. 4 being joined thereto and forming a partthereof, .by any .suitable means well known in the art. -;It is to be noted that the front wall of said sectionat its upper portion has a square opening 14 continuing along. a reduced. slot section [5 and a wider slot section l6 of theintermediate upper horizontal plate member shownin Figs. 3 and 4. It is to be noted that the front wall is also provided with an opening. l2 intowhichfits a screw or rivetmember l3 for pivotally holding a safety catch E, while the upper horizontal'plate has an opening 13' for a verticallyextending rivet member I4" to pivotally retain check D .as shown in Fig. 1. Said check D has an opening 26 at one end tobe mounted on the rivet as an axis and has spaced upwardly extending lugs or ends 21 and 28 adapted to fit into opening M and permit retention thereof by means of. said catch E. Said opening I4 is thereby closed .by'said spaced ends of the catch.

- Thelower horizontalplate is' provided with a curved slot H, disposed substantially parallel to upper slot l5 and I6, and a guide slot having portions l8 and I9.

* Mounted on the upper horizontal plate mem-' with one end having a plurality of side walls 2|] and 21 respectively and a face wall 22 integral therewith as shown in Figures 1, 2, 3 and 4. Said vertical side walls are provided with a plurality of openings 30 for accommodating rivet members shown in Fig. 4 and to permit fixing of the movable hinge end to the walls B of an automobile door or other vehicle. Said hinge member furthermore has an outwardly curved arm extending from said walls and is of suff cient length for fitting into the space between'the horizontal parallel plates. An opening 3| is provided in the end of the curved arm portion for accommodat-;,;

ing a pintle 36. It is to be noted that said pintle 40 and .M. Portion 31 is adapted to accommodate a pinion or cog F, while fiange38 is adapte'd to slide in groove or slot [6. Intermediate flanges 38 and 40 is a recessed portion 39 which acts as a guidemaking contact with the. sides of slot (portions l5 and "'lfi'when the movablehinge member is inserted into operable position in the fixed section of the hinge: Flange of the pintle is adapted to fit in hole 3| of the curved arm and form an integralpart of the arm; while flange 4| forms the lower part of the pintle and is adapted to travel in slot ll in the lower horizontal plate.

In order to limit theoutward and inward movement'ofsaid hinge member GH, there is provided a' guide member 32 adapted-"to fit in recess 35. provi'ded therefor onthe curved portion of'said member. Said member 32 has a recessed portion 33 adapted totravel in slot I9 as shown in Fig. 1, and: a flange 34 in thelower part of the'guide for-"retaining themember when traveling inslot 19. It'is to be noted that once-the movable hinge member .G'H is mounted, it can be slid inorout as"desir-ed.without coming apart from the fixed non-movable portion mounted in section A, as shownin-Figs. 1 and 2 of the draw- 111g, In order to assemble and operaite'the device as disclosed herein, the pivoted safety'catch member E is swung about. its pivot so that the free end thereof is raised toforin contact with the spaced lugs orends 21 and 28 of check.D. Said check D is. swung outwardly on its pivot to permit the insertion of thegpintle 31- int-o slot sections [4, I5, lBzand llandthe insertion of guide member. 32 into slot sections IBand l9. Pinion F mounted on the upper'en'd pf pintle .36 is retained in position thereonby means .of a. pin member; not shown, adapted to fit'in opening 36 thereon. Said pinion is above the upper horizontal plate of the fixed hinge sectionv C and is adapted to be in engagement'with either rack L when-the vehicle-door is to be closed or with rack M when the vehicle door is to be opened. Once the pintle and guide-,member are in the fixed section of thehinge,-check D is closed and engaged with catch member E as shown in Fig. 1. It is to be noted that the space: intermediate the two horizontal plates-forming fixed section A, is of sufficient depth. to permit slight .raising of hinge member Q- H.for proper insertioninto the slotsabove indicated without permitting any unnecessary rattlingor looseness.v The flat metal plate 43 as heretofore shown in Fig. 5 is-inserted into-the formed box 23 as shown and is attached to the upper Wallofsaid box tokeep guide 32 in relatively operative position when-section- GH is actuated. 5 In operating the hingeabove described, the m a s t t ins mo n ed o to a door other vehicles or" of buildings. l mountediand the width of the fixed portion can may be moved in and out of section C. In such cases, the pintle 36' having parts 38, 38, 40 and 4| mounted on curved arm GH moves in slot sections l5, l5 and '11 while guide member 32 moves in slot sections 18 and i8 and retains the movable section of the hinge in operable position without becoming separated from fixed section C. Pinion F mounted on pintle 36' revolves thereon and forms an engagement with rack M when the dooris to be opened and with rack L when the door is to be closed. By the use of said racks there is an even distribution of the Weight of the vehicle door on the hinge and of the stress on the fixed section of the hinge.

-' The device as described is adapted for either straight line or curved doors of automobiles or It can be easily be varied to suit the particular type of application. Also, the device permits of a relatively snug fit in the door frame,.while .the removable portion is fixed to the door by means of rivets or like means.
