UNITED STATES CHARLES R. BELK, OF PITTSBURGH, PENNSYLVANIA.

HINGE STRUCTURE.

Application filed December 7, 1923.

T all whom, t may concern.'

Be it known that I, CHARLES R. BELK, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Hinge Structures; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art. to which it appertains to make and use the same.

This invention relates to new and useful improvements in hinge structures and more particularly in adjustable hinges adapted for use for supporting the smoke box front on locomotives.

The object of the present invention is to provide a device of the character indicated of an improved and simplified structure by means of which the strength of the device is increased, while its range of adjustment is maintained.

The present invention constitutes an improvement upon the subject matter covered by my previous Patent No. 1,459,872, dated 'lune 26, 1923.

The invention consists in a novel construction, arrangen'ient and combination of parts as heretofore more particularly described and claimed.

One sheet of 'drawings accompanies this specification as part thereof in which like reference characters indicate similar parts throughout.

Figure 1. is a fragmentary view of hinges embodying the present invention applied to the smoke box front of a locomotive, the tro-nt being shown in open position.

F ig. 2 is a horizontal cross sectional view through a part of the locomotive showing the smoke box front closed and the improved hinge in plan partially broken away to illustrate details.

Fig. 3 is a fragmentary longitudinal section through a hinge taken on a line corresponding to that indicated by the line 3-3 of Fig. 1.

My improved hinge comprises a body part 1 which may be provided with lateral flanges 2 2 adapted to be secured to the locomotive body B, as by rivets 3 3.

The body 1 is provided with a longitudinally extending slot 4 Within Which is a member 6 pivoted, as by bolts 7. The member 6 is provided adjacent one end with a slot 8 adapted to be engaged by a nut 9 Serial No. 679,209.

having' an annular groove 11 adapted to slide in said slot 8, the nut being threaded upon a similarly threaded nut 10 secured to the body 1.

By means of the nut 9 it will be apparent that the member 6 can be swung upon the pivot bolt 7 within slot 4 of part 1 and a bolt 26 is provided threaded through a suitable hole in one side wall of the slot 4 adapted to engage the member 6 to lock the same in its adjusted position relative to part 1. The other end ot part 6 is preferably bifureated, forming parallel spaced arm members 13--13- The second principal part of the hinge member comprises an angular member 14 having one end provided with a face plate 15 adapted to be secured to the door D, as by rivets 16, the other end of the member 14 being bifurcated to form spaced parallel arms 17-17 between Which the arms 13-13 of the member 6 are adapted to seat.

The arms 17-17 are provided with slots 18-18 and a pivot 19 is adapted to pass through the slots 18-18 and through suitable holes in the members 13-13 to secure said parts in pivotal relation.

The member 14 is provided with a bridge part 20 intermediate the arms 17-17, the bridge member having a slot adapted to receive a nut 21 provided with an annular groove 22 of a diameter corresponding to the slot in the bridge member 20.

The nut 21 is threaded upon an eye bolt 25 through the eye 24 of which the bolt 19 passes, the bolt 25 being positioned between the arms 13-13 of the member 6.

By rotating nut 21 it will be apparent that member 14 may be adjusted with respect to member 6 through the range of slots 18-18, the eye bolt 25 operating upon the pivot bolt 19 to advance or retract the member 14 with respect to the arms lf3-13 of the part 6.

It will thus be apparent that the door D can be removed from the boiler B While being mantaine'd parallel thereto to clear the securing bolts b commonly used for securing the doors in position and that after these bolts have been cleared the door can be readily swung upon the pivot bolts 19.

By reason of the improved structure thus described, it will be apparent that the hinge structure is materially strengthened by means or" the pivot bolts 19 securing the principal members 14 and 6, which pivot bolts can be made oi sturdy construction and require no adjustment in use;

hlodilications will rea'dily suggest themselves to those skilled in the art but within the scope of the present invention, as claimed.

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

l. An improved hinge structure, including two members pivotally and slidably connected with respect to each other, a common pivot member connecting said members, means' for slidablyadjusting said members comprising. an eye bolt pivoted on the said pivot member', and means for varying the relation of said eye bolt with respect to one of thehinge members.

2. An improved hinge structure compris'- ing an attachment member, a member pivoted with respect to the attachment member, said pivoted member having a slotted member, an eye bolt adjustably mounted on the pivoted member 'so that its eye coincides with and is adjustable longitudinally of the slot.

3. An improved hinge structure comprising` ya' swinging member adapted to have one end secured toa movable part and having its other end bifurcated to form two spaced arms, said arms being provided with slots, a bridge member intermediate said spaced arms and having a slot in alignment with the slots in said' spaced arms, a second hinge member having one end bifurcated and adapted to seat between the spaced arms of the swinging member, the arms of said second 'member being provided with holes adapted to receive a pivot bolt, an eye bolt adapted to be seated between the arms of said second member, a pivot bolt adapted to pass through the slots in the arms of the swinging member, the holes in the arms of the second member and through thel eye of the eye bolt positioned intermediate said last mentioned arms, and a nut having an annular groove adapted to seat in the lslot of the bridge member and to be threaded upon said eye bolt, substantially as speciied.

In testimony whereof I aiiiX my signature.

CHARLES R. lBELK.
