J. STRACHAN. HINGE,

No. 375,394. Patented Dc. 27, 1887.

JOSEPH STRAOHAN, OE BROOKLYN, NEWYORK.

HINGE.

SPECIFICA''IONA forming part of Letters Patent No. 375,394, dated December 27, 1887.

Application filed June 18, 1887.

To @ZZ whom it may concern:

Be it known that I, JOSEPH STEAOHAN, a citizen of the United States, residing in Brooklyn, county of Kings, State of New York, have invented a new and useful Improvement in Hinges; and I hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompany- Y ing drawings, which form part of this specification.

The object of my invention is to provide a flush hinge in which there will be no projecting parts above the lid or hinged portion when it is closed and in which the parts of the hinge will move easily upon one another and not be liable to get out of order.

My invention is shown in the accompanying drawings, in which Figure l is a top view of my hinge. Fig. 2 is a side view with a part broken away. Fig. 3 is a vertical sectional view on the line 3 3 of Fig. 1,showing the hinge nearly open. Fig. 4 is a vertical sectional view on the line-l 4 of Fig. l. Figs. 5, 6, 7, 8, 9, and 10 are detail views of. the various parts of the hinge, Figs. 8 and l() being sectional views on theliues 88 and l0 10 of Figs. 5 and 7, respect ively.

Referring to the drawings, A is the part of the hinge to be fastened to the lid. or object which is to be mounted on the hinge.

B is the part of the hinge connected with the fixed part to which the -hinge is attached. Fastened to the under side of the part B is a semicircular box, F, adapted to receive the movable parts of the hinge. Inside of the box is placed the track g, which I prefer to construct of a central upright member with two flanges at its top. Attached to the under side of the part A are the slides b b', which I prefer to make semicircular, in the manner shown. Between these slides,b b I prefer to have a connecting portion, c, also semicircularin shape, for the purposes hereinafter mentioned.

E is the connecting-slide by means of which the parts A and B are held together in operative position. This connecting-slide E is provided with a groove, m, to receive the track g and enable the. oonnectingslide to move upon the track. The connecting-slide is so shaped 5o or curved that it will move freely and easily Serial No. 241.731. (No model.)

in the box F on the track g. This connectingslide is also provided with slots n u, which do not extend the entire length of the slide. Stoppins h h, fastened to the box F, project into these slots n n, so that the connecting-slide is prevented from being drawn outv of the box F. The slides b b are connected with the connecting-slide E by means of the dentals d d, fixed in the slides b b, and the slots o o,in which the dentals d d work. The slots o o do not extend the entire length ofthe connecting-slide. From the fixed part B a projecting portion, l, extends over t-he end of the track g, in order to prevent the connecting-slide E from being drawn out of the box F at that end. The projecting portion Zills up a recess in the adjoining end of the part A, which recess is necessary to permit the connectingslide E to pass the end of the part A when the hinge is opened.

In operating the hinge,when the lid is raised the' slides b b are moved in the box F and are controlled in their motion by the dentals d which move in the grooves 0 o. When the part A has been raised and the slides b b moved some distance,the dentals d d will strike against the ends of the slots o o, and the connectingslide E will then be moved on the track g until the part A is turned entirely back and rests Iiatly on top of the part B, as shown approximately in Fig. 3. In reversing the motion of the hinge the part Ais raised from its position on the part B,causing the connectingslide E to move back on the track g. When the inner end of the connecting-slide E strikes the projecting portion or arm Z,its motion is arrested, and the slides b b then move'on the connectingslide by means ofthe dentals d cl and slot-s o o until the lid is closed. The stop-pins 7L h,pro- `jecting into the slots a n, prevent the connecting-slide E from being drawn out of the box F.

I prefer to connect the slides b b with the circular portion c, as lthis enables the slides b b to move more easilyand smoothly on the connecting-slide E.

Thus when my hinge is closed the parts A and B are flush with each other and have no projection from their upper surface. When the hinge is opened, the lid or part A will rest atly and evenly on top of the part B.

The operation of my hinge is simple. It is IOO not liable to get out of order, as its working parts are protected by the box F, and it is inexpensive.

XVhat I claim as new, and desire to secure by Letters Patent, is-

1. A iiush hinge, substantially as shown and described, consisting of an outer semicircular box attached to the iixed object and projecting therefrom, a connecting-slide shaped to fit the interior of the box and adapted to move upon its inner surface,and a semicirenlar slide attached to the lid,sliaped to fit the interior of the connecting-slide,and adapted to move upon its inner surface, and dentals for holding said parts together and limiting their motion.

2. A hinge, substantially as shown and described, consisting of the circular slide connected with the lid or object to be hinged,the

circular connecting-slide provided with a series of grooves, the dentals projecting from 2o JOSEPH STRACHAN.
