STRAP-HINGE.
' SPECIFICATION forming part of Letters Patent No. 257,022, dated April 25, 1882.
Application filed June 3, 1881. (No model.)
To all whom it may concern Be it known that I, WILLIAM M. KURTZ, of Columbus, in the State of Ohio, haveinvented certain new and usefulImprovements in Strap- Hinges, of which the following is a specification.
It is my object to obtain a stronger straphinge than the ordinary strap-hinge of eominerce without increasing the size ot'the hinge or materially enhancing the cost of manufacture. To this end, in lieu of providing both strap-leaves with the ordinary tubular-knuckles which receive the pintle, I form one of the leaves with side ears or flanges which stand at right angles to the body of the strap-leaf, and are formed with holes to receive the pintle, the said ears and the body of the strapleat' being made out of one piece of metal. The otherstrap-leaf is provided witha knuckle which encircles the pintle, and is held between the upturned ears or flanges of the first leaf, and with the pintle and the ears or flanges which receive it I combine independent external re-enforcing blocks, which receive the outer ends of the pintle, are bolted or fastened to the structure to which the flanged leafis.
secured, and serve to support, re-enforce, and strengthen the ears.
The nature of my invtntion and the manner in which the same is or may be carried into effect will be understood by reference to the accompanying drawings, in which Figure 1 is a perspective view ofa strap-hinge embodying my improvements in their preferred form. Fig. 2 is a section on the line 1 1, Fig. 1. Fig. 3 is a view of the flanged strap-leaf. Fig.4c is a view of one of the strengthening blocks or pieces.
A is the strapleaf which receives and holds the pintle. It is for this purpose formed out of one piece of metal, with upturned side .ears or flanges b at its front end, which ears are perforated, as shown, to receive the pintle a. The other leaf, B,is formed with a tubular knuckle, 0, which tits snugly between the two ears I), andisthere held by the pintle c,which, after passing through the ears and the knuckle, has its ends upset or otherwise enlarged, so as to bind all parts firmly together, preventing the ears from spreading without, however, cramping the knuckle c to such an extent as to prevent it from turning upon the pintle. In t-l is way a strap-hinge is obtained which possesses about twice the strength of the ordi nary strap-hinge of the same size, and can be manufactured almost as cheaply as the latter.
For the purpose of re-enforcing the ears or flanges b, -I place outside of said ears or flanges separate and independent supporting blocks or pieces 0, preferably of wroughtiron or inalleable metal, which aresecured to the same structure to which the leafA is fastened, and receive the outer ends of the pintie, which should, as shown, he of such length as to pass through and project at each end beyond the blocks 0. The pintle is supported and held by both the ears and the blocks, and the latter by the rivet are drawn up against the ears, re-eni'orcing and supporting them and adding appreciably to the strength and durability of the hinge.
Having described my improvements, what I claim, and desire to secure by Letters Patent, 1s
A strap-hinge consistingof a strap-leafprovided with upturned side ears or flanges, and
external to said ears, in combination with a strap-leaf formed with a tubular knuckle re ceived between the two ears of the other leaf,
ears, and external re-enforcing blocks, under the arrangement and for operation as hereinbefore shown and described.
Intestiinony whereofI have hereunto set my hand this 8lst day of May, 1881.
