Specica'tion of Letters Patent.

Painted Nov. 30., 1909.

Application filed March 31., 1909. Serial No. SZOOSL To all whom 'it may concern:

Be it known that I, HARRY R. .CANr1si.D, a citizen of the United States, and residing at New York, in the c ounty of New` York and State of New York, have invented cer'- tain new and useful Improvements in Invisible Hinges, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same. Y

This invention relates to what are known as invisible hinges; and the objectI thereof is to provide an improved device of this class designed for use in connection with doors, gates, sashes or the like, and also piano and organ constructions and in cabinet work of various kinds and classes; and with this and other objects in View the invention consists in a hinge of the class specified constructed as hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which 3 Figure l is a side view of a hinge made according to my invention and` looking in the direction of the arrow a: of Fig. 3, Fig. 2 a section of the hinge on Fig. 1 and showing the hinge applied to a door frame and door, and showing the door i in a closed position, Fig. 3 a view similar to Fig. Q-butshowing the door open, Fig. 4 a view similar to Fig. i but showing only part of the-hinge and showing a modification, Fig. 5 a partial transverse section on the line 5--5 of Fig. 4, Fig. 6 a section on the line 6 6 of Fig. 1 but showin a modification and showing the hinge app ied to adoor and door frame, and showing the door in a closed position, and ;-Fig. 7 a view similar to Fig. 6 but showing'the door open.

In the drawing forming part or" this specication, l have shown at fa part of a door frame and at d5 a partvof adoor.2 and inthe practice of my invention provide a hinge comprising two similar ,Imam plates or leaves a and b which are preferably formed by folding asheet of steel or other metal longitudinally, and these plates or leaves are plate cl with a transversely ranging arm vwith the main hinge plates knuckles (Z2 of the supplemcnta chambers f2 and.' d6

provided with knuckles a2 and2 respee tively.'

l. also provide two supplement-al. hinge plates c and (l, and these hinge plates c and d are pro vided at their oppositeedges with knuckles c2 and d2 respectively clearly shown in Fig. 1., and the supplemental hinge plate c is provided with a transversely rang ing arm o, and the supplemental hinge 113. and the main hinge plates or leaves a and are provided with transversely. ranging recesses a3 and b3 adapted to receive the arms Z3 and c of the supplemental hinge plates c and d.. The supplemental hinge plates'c and fl are connected by a pintle Vpin e passed through the knuckles c2 and Z2 at one edge thereof, and the said supplemental hinge plates c and (l are connected respectively l) by pintie pins f3 and g as shown in Fig.

l, one of said pintle pins being passed' through the knuckles oi the plate or leai2 c and thecorresponding knuckles of the sup plemental hinge plate o, and the other being passed through the knuckles b2 of the main hinge plate or leaf Z) and the corres ending l) hinge plate al.

When the parts of the hinge are connected inthe manner described and as shown in Fig. 1, the arms c and di of the mental hinge plates c and el enter and will swing in the transverse recesses b3 and a3 in. the inner or adjacent side edges of the plates or leaves (L and l), and said arms c? and (Z3 are slotted longitudinally as shown at c* and nl* in Figs. and A3, and passed through the lower end portion of the main hinge plate or leaf o: and the upper end portion or' the main hinge plate or leaiz b are pins /t and i which pass through the slots (Z4 and c* in the arms al and e. ln practice themainhinge plates a and Z are secured inf` the frame f ofthe door d5 `or leaves a and supple and in the door d5 as shown in Figs. 2 and 3, Y

and said plates o r leaves are counter sunk in the frame and door as clearly shown in said ig'ures, and-*the said #frame and door are also provided respectivelyv with recesses or adapted to receive the land door as clearly shown in Fig. 2, and the said door may be swung through an arc 0i one hundred-and eighty degrees as shown in Fig. 8, and in the movement of opening the door it is swung clear of the door frame so as to avoid any moldings or ornamental work with which saidvdoor frame may be.

provided, this operation being clearly indicated in Fig. 3.

With `this construction the door must be opened and closed by hand, but in Figs. 4 and 5 I have shown means whereby the door may be automatically closed and held in the closed position, In order to accomplish this result I provide a spring j which is wound on the central pin or pintle e, and which is provided with twoarins and j3 which are wound around or partially around the pintle pins f3 and g, and this spring is preferably placed centrally of the hinge, but may be placed in any desired position and a number of said springs may be provided if desired, and in order to accommodate the sameV the li'nuckles'of the plates or leaves a and b and ot the supplemental hinge plates o and d are shortened.

In Figs. 6 and 7 I have shown a modificatiorl of this spring construction, in which I place either in the door frame or door, in

the door frame as shown in the drawing, and in the recess or chamber f2 therein a spiral spring 7c, and the arm cl3 of the supplemental hinge plate d is connected by means of a link 7a2 with a disk or plate /03 on which one end ot' said spring bears, the

. other end thereof bearing on the main hinge plate or leaf ,and the spring c will operate as will be readily understood to close the door Z5 and hold it iiia closed position.

It will be understood, of course, that if the spring /a is used in the door instead of being used in the door frame, the said spring will be placed in the chamber or recess d and will he'connected with the arm o3 of the supplemental hinge plate c, and said spring device may be used both' in the door l? and door i'raiue f if" desired.

It will be observed that the knuckles a,2 and b2 on the plates or leaves a and b are ofset at one side of said plates or leaves so that the centers of said knuckles are not in the central planes of said plates or leaves, and it will also be observed that the arms 03l and el of the supplemental hinge plates c and Z are wider where the pintle or pin c passes therethrough than at the opposite ends, and the longitudinal slots c and d4 in said aimsY are curved inwardly of the pivotal support orl connection formed by the said pintle c, and this construction enables the separate parts of the hinge to` fold together as shown in Fig. and also facilitates the movement of said parts in the beginning of the opera tion of opening the door.

' lt will be understood that my improved hinge may he made of any desired strength, and the arms c3 and dlvof the supplemental hinge plates c and d may also be made of much greater relative dimensions or strength than herein shown and described if found necessary. I

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A hinge composed of two main lates or leaves and supplemental plates hinged thereto and to each other, said supplemental plates being provided with arms which enter transverse recesses in the main hinge plates or leaves and which are provided with ongitudinal slots, and said main hinge plates or leaves being provided with stationary pins which pass through said slots.
