METALLIC HAME.

SPECIFICATION forming part of Letters Patent No. 240,735,dated April 26, 1881.

Application tiled November 11, 1880.

To all whom it may concern:

Be it known that I, EMMIT G. LATTA, of Friendship, in the county of Allegany and State of New York, have invented new and useful Improvements in Metallic Eames, of which the following is a specification, reference being had to the accompanying drawings. The Object of this `invention is to produce a cheap, light, and durable haine which will Vfit the collar better than those now in common use, and in which the parts which are liable to become worn or broken can be easily replaced, and the parts of which are readily molded, cast, and put together. My invention consists, first, of an open-bac metallic hame constructed on its inner edge with a projecting ange which is adapted to iit under the rim of the collar, whereby a better tit of the hame against the collar is produced; second, of an open-back metallic hame constructed on both its inner and-outer edges with projecting iianges, whereby tliestrengtli of the hame is increased anda better fit of the hame against the collar is" produced; third; of a metallic haine constructed on its outer side with a slot for the reception of the drafteye; fourth, of a metallic hame constructed on its outer side with a iiange having a slot formed in it for the reception ofthe draft-eye, the flange being re-enforced around the slot to a'ord a iirm bearing for the shank of the draft-eye, fth, in combination with a hame provided with a slot for the reception of the draft-eye, of a draft-eye having a shank engaging in said slot and adapted to be secured to the hameby arivet or screw; sixth, of a metallic hame provided with sockets for thereception of the terret or rein-ring; seventh, of the particular construction of the sockets whereby they are enabled to be cast without cores; eighth, in the combination, with a metallic hame provided with sockets forthe reception of the terret or hamering, of a terret or hame-ring provided with a shank which is adapted to be introduced into the sockets of the hame and secured therein by strengthening the shank; ninth, of a metallic open-back hame constructed with` a series of projections on its inner rear side. to receive an adjustable `5o hame-strap loop; tenth, in combination with` (No model.)

` strap loop in which the side bars are bent in opposite directions to permit the pattern to be drawn from the sand, and to facilitate the insertion of the hame-strap. 6o

In the accompanying drawings, consisting ot' two sheets, Figure 1 is a rear elevation, and

Fig. 2 a front elevation, of my improved hame.

` Fig. 3 is a fragmentary sectional elevation of `the upper part of the hame on an enlarged scale. Fig. 4 is a horizontal section in line l i l, Fig. Fig. 5 is a front elevation, on an enlarged scale, of that part of the hame to which the terret is attached. Fig. 6 is a rear elevation of the same. in line 2 2, Fig. 5. Fig. 8 is a detached view of the terret previous to applying it to the hame. Fig. 9 is a `cross-section of the hame applied to the collar. Fig. 10 is .a cross-section ofthe hame, showin g a moditiedform thereL 7 5 of. Fig. 11 is a cross-section in line 3 3, Fig. 2, o1i` an enlarged sale. Fig. l2 is a vertical section in line 4.4, Fig. ll, on an enlarged scale. Fig. 13` is a detached view of the draft-eye. Fig. 14 is a detached view of the lower hame- 8o strap loop. Figs.15 and 16 showniodified constructions of the terret.

Like letters of reference refer to like parts lin the several figures. v

A represents the body of inyiinproved hame, 8 5 made of semicircular or similar cross-section, with an open or depressed back, and having laterally-projecting iianges a a on the inner and outer edges of the body of the hame.

B represents the upper hame-strap loop, C` 9o the terret or rein-ring, D the draft-eye, and- E the lower hame-strap loop.

The llanges a a extend from the lower portion of the hame, where they run out into nothing, upward to apoint below the terret', where` 95 they also run out into nothing, and are widest near the draft-eye, as clearly shown inFigs.

l and 2. The i-nner'flange, a, is adapted tot` under therim of the collar, and both flanges are shaped to lit snugly against the collar, roo

Fig. 7 is a vertical section 7o` whereby the hame is given a firm bearing against the collar and a close fit of the parts is produced. The hame has about the same thickness of metal throughout the entire length of its cross section, as clearly shown in Fig. 9, and the flanges a a greatly' increase the strength of the hame and permit the same to be made light.

f represents several projections formed on the inner rear side of the hame, at the upper portion thereof, at suitable distance apart for holding the upper hame-strap loop, B, in the proper position. The loop B is composed of' a narrow portion which surrounds the hame, and a wider portion through which the hame-strap is drawn.

g is a tongue or stop projecting inwardly from one of the side bars of the loop, and arranged in such manner that when the hamestrap is disconnected from the loop the stop g will pass by the projections f of the hame and permit the loop to be freely raised and lowered. Upon passing the hame-strap behind the inner bar ot' the loop the latter is drawn inward, so as to bring the stop g between two of the projections f, whereby the loop is held against vertical movement. By this means the loop B is readily adjusted on the hame, and secured in the desired position without obstructing the outer surface of the hame by corrugations, as heretofore practiced.

h h are two sockets, formed one above the other on the outer side of the hame for the reception of the shank of' the ter'ret C. The sockets 71. open toward each otherthat is, the upper socket opens downward and the lower socket upward. i

t represents an opening, formed in the rear side of each socket, h, and communicating with the recess of the socket, so that the pattern can be drawn from the sand, thereby avoiding the use of cores.

lq represents the shank of the terret, which is provided with two arms, which are adapted to en gage in the recesses of the sockets h. One of the arms of' the shank lc, preferably the upper one, is made longer thanthe lower arm, and bent as shown in Fig. 8, and the upper socket, h, is made correspondingly longer, so that the upper bent end of the shank can be passed into the upper socket far enough to drop the short lower end into the lower socket. This being done, the Lipper bent arm of the shank is straightened out, as shown in Fig. 6, whereby the terret is firmly attached to the hame.

Instead of constructing the terret C with a bent shank, which is straightened after its ends are inserted in the sockets, the terret maybe constructed of spring metal, as represented in Figs. 15 and 16, and sprung into the sockets.

. The draft-eye D is constructed with a fiat shank, L, which is passed through a vertical slot, Z, in the outer flange, a', of the hame, and which bears against the rear side of the body of the llame. The groove or depression in the back of the body of the hame is filled up at this point, so as to form a bearing for the flange or shank L. The flange c is also re-enforced or made thicker around the slot Z, to afford a firm bearing for the shank of the draft-eye. m represents a rivet or screw whereby the shank L of the draft-eye is secured to the hame. When the eye has become worn by use, it is readily detached by removing the rivet or screw m, and replaced by a new one. The shank L of the draft-eye rests in a depression formed in the outer flange, a', of the hame, and the rivet is substantially relieved from all strain in pulling on the draft-eye.

N is the eye or loop to which the holdbackring is attached. It is preferably formed in one piece with the draft-eye, as shown, but it may be formed at the outer end of the rivet m, by which the draft-eye is secured to the hame.

'Ihe lower hame-strap loop, E, has its side bars, o, bent or curved in opposite directions, one outward and one inward, as clearly shown, whereby the pattern is enabled to be drawn from the sand, and the use of cores in casting the loop is avoided, and the shape of the loop rendered more suitable for an easy attachment of the hame-strap, since the front bars of the two loops are curved in opposite directions or away from each other and permit the fingers to en ter between the front bars, even when the loops are brought closely together.

The parts of' my improved hame are each easily molded and cast complete of malleable iron, and readily put together.
