HINGE.-

SPECIFICATION forming part of Letters Patent No. 727,653, dated May 12, 1903. Application filed June 7, 1901. Serial No. 63,548. (No model.)

To all w/tom it "may concern:

Be it known that I, GEORGE A. LONG, a citizen of the United States, and a resident of Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Hinges, of whichthe following is a full, clear, and exact description, whereby anyone skilled in the art can make and use the'same.

Myinvention relates to the class of gravityoperated hinges; and the object of myinvention is to provide a hinge, more especially applicable for use in a telephone toll-collecting apparatus, which shallcertainly insure the automatic closing of the door of the case or box containing the telephone set, and, further, to provide a hinge for such use the ease of operation of which shall be such as to insure the automatic closing of the door when it has been opened. A device by the use of which these objects maybe obtained is illustrated in the accompanying drawings, in which- Figure 1 is a view in front elevation of a telephone case embodyingmy invention. Fig. 2 is a view in elevation, on enlarged scale, of a portion of the door and case, showing my improved hinge. Fig. 3 is a like view, but showing the portion of the door raised 0 and hinge parts separated. Fig. 4 is a detail view in cross-section through the hinge. Fig. 5 is a view in central vertical section through the hinge.

My invention is illustrated and described 3 5 herein in connection with a box or case within which a set of telephone instruments is inclosed and forming a street-telephone apparatus, the inventionbeing especially adapt ed for use in connectionwith such an apparatus in which a coin is used for the purpose of opening the door to gain access to the tele-' phone and which is recovered after thedoor has been opened. In such an apparatus it is necessary that the door shall be readily closed after the instrument has been used,

and to this end it is essential that mechanism for closing the door shall be provided which shall be positive in its operation at all times and under any conditions of weather.

To accomplish this result, I have constructed a hinge of the gravityoperatedtype and have so arranged and constructed the parts that they are not liable to become inoperative in use.

In the accompanying drawings, the letter a denotesia 'post or standard supporting a box or case b of astreet-telephone. This box or case is providedwith a door 0, having a handle a, by means of which the door may be unlatched for the purpose of opening. This door 0 is provided, preferably at the back and near each end, with the socket member 01 of the hinge in the form shown, this socket member being preferably castintegral with the door. A socket d is formed in'the socket member, the bottom (1 of the socket being formed on an incline or slope prefer ably extending in a straight line across the socket membe'r.-

A pintle member e issecured to the box or case, in the form shown being cast integral therewith, this pintle member having a pin or pintle e extending upward and of a diameter to so fit within the socket d that the socket member at may be easily turned on the pin and will at the same time completely inclose the working surfaces. The end e of the pin is formed on a slope or incline corresponding to that of the bottom d of the socket d and preferably extending in a straight line across the pin. This slope or incline on the bottom of the socket and end of the pin is so formed that the two surfaces lie flat against each other when the door is in the closed position.

It is important in providing an inclosing casing for the purposes herein described that the door, as well as the main portion fof the casing, have a considerable weight; and of course it is imperative that the doonbe let into and tightly fit within the casing in order to exclude moisture, sleet, and dirt. [It is also important. that with sucha heavy door it should swing to closed position with as little jar as possible and that a means be provided to prevent its rebounding. With the construction of binge herein described the end of the pintle and the bottom of the socket are in registering positions just as the door reaches its closed position, and as the coacting surfaces are arranged in the same plane transverse to the axis of the pintle and socket a sort of stop is formed, which cases the closing of the door and tends to prevent its rebounding.

It will be noted from the above construction that all of the bearing parts are inclosed and there is little chance of dust or dirt gaining access to the inclined surface between the bottom of the socket and pin, so as to injuriously affect the working of the device. It will also be noted from the above construction that the means for automatically closing the door and for maintaining the engagement of the hinge members are included in the socket and pintle--that is, a separate pin is socket.
