IMPROVEMENT IN DOOR-HING-iElS.

The Schedule. referred to in these Letters Patent and making part of the same.

To all whom it ma/y concern Be it known that I, Aaron W. WALTER, of Canton,

in the county of Stark, and State of Ohio, have in vented new and useful Improvements in Door-Hinges; and I do hereby declare that the following is a full, clear, and exact description of my invention, reference being had to the accompanying drawings, forming part of this specification, and to the letters of reference marked. thereon, of which drawings- Iliigure l is an elevation ofa strap-hinge constructed on my improved plan.

Figlu-e 2 is a plan oi' the same.

Figure 3 is .an elevation of another formof hinge,

constructed on my improved plan Figure 4 is a plan of the same. The nature of my invention consists, first, in forming the eyesoi the hinge by turning over the edgesof the hinge-blanks, and drilling .holes in said edges, through which tl 1c hingepiu is passed, instead of forming bent eye-holes by rolling up the ends of the blanks, as has bee]r'heretoibre the practice, whereby Iobtain a hinge much stronger than the old form of hinges,- and which can be nianuiactiu'ed at a less cost, both of labor and machinery, and also with little of the waste of nutterial caused by the breaking of the iron in forming the eyes of the hinge, by'the old plan of rolling up the ends of the blanks, thereby lessening the cost of the hinges, and adding considerably to their utility; second, in combining with a hinge formed as before shown, a spiral spring, which sets around the hingepiu, and is connected at each end with one of the leaves of the hinge, in such a manner as to cause the two parts of the hinge to close or open by the actionof said spring, as may be desired, whereby I obtain a very eheapand eilicient spring-hinge.

To enable others skilled in the art to make anduse my invention, I will proceed to describe its construction and operation. 1 a

The strap-hinge, shown in figs l and 2, has the two leaves, A and B,oftheus1utl form, but instead of having lips left at the joint-ends, to be turned intoeyes,

the lips O O and D 1) are left at the sides ofsaid leaves,

and are turned down at right angles to said leaves, as shown.- I

The hinge-pin ll, inning a head, 0, formed at one lilil, is then put through suitable holes made in the lips O C and D D, and the head (I being formed on said pin after-its insertion in the hinge, the hinge-joint is completed. a i

'lhe lips D D, on the leaf B, are arranged so as to come inside the lip G O on the leai'A, so that nostrain of any great amount is brought on the heads (I c of the hinge-pin E, by the weight of the door.

Where iin'open spring-hinge is to be made, the spiral spring Ffis inserted between the lips DD, the ends f and g bearing against the leaves B and A, as shown when the hinge-pin E is passed through the eyes 0 O and'l') D, and the centre of the spring E, and the head (Z being riveted, as before, the spring-jointis complete.

When aclosed spring-hingeis to'be made, the-ends f and g are secured to the leaves A and B, by turning their ends at right angles,'and passing them into suit a le holes in said leaves, where they are secured by riveting, or they may be secin'edin any other-suitable manner. f

The spring E, being made in this last case with the ends f and r parallel to eaeh'other, and extending in the same direction from the spring, it is easily seen that a closed spring-hinge would be formed, instead of an open hinge, as here shown. I

1n the hinge shown in figs. 3 and 4, the leaves A and B are made in a u-form, as shown, andthe lipsC O and I) D are turned up from the inside of said u,-as shown, the pin E being inserted andsecured as before shown.

The spring 'E is arranged on the pin E,'.between the lips O O, in a manner precisely similar to that shown in figs. 1 and 2, and the ends f and' are secured to the leaves A and B by being inserted through holes in the lips 1) and O, as shown. The manner of arranging the I spring F, in order to obtain an open or closed spring-hinge, is too obvious to any mechanic to require particular description;

, The leaves A and B nia be made of wrouglit-iron, steel, brass, or any other malleable 'metal, of such quality that the eyes or lips G 0 and D 1) may be turned at right z ngles to the leaves A and B, as has been before shown. Q

Having thus fully described my improvements, I do not claim as my invention the leaves A and B, shown in figs. 1 and 2, nor the U-form of the leaves A and B, shown in ligs. 3 and 4, nor the hinge-pin E, nor the spring taken separately, or inconibination with other forms of hinges; but

hat I do claim as new, and desire to secure by Letters Patent, is p 7 1. A hinge, composed of two leaves, having eyes or lipsturned up at their outer or inner edges, and com bined with a hinge-pin, substantially in the manner and for the purpose herein specified.

2. In combination with a hinge, ,constructed as herein specified, a spiral spring, F, arranged and used substantiallyin the manner and for the purpose specified.

As evidence 1 claim the foregoing, I have hereunto set my hand in presence of two witnesses.
