IMPROVEMENT IN GARRIAGES.

TO ALL WHOM IT MAY CONCERN:

Be it known that we, T. W. PORTER and H. K. PORTER, ot Boston, in the county of Suffolk, and State of Massachusetts, have invented a new and useful Improvement in Cai-riegos; and we do hereby declare that the' followingis a full, clear, and exact description of the construction and operation of the samefreierencevbeing had to the accompanying drawings, ina-king a part of this specification, in which- Figure 1 is a perspective View of a side-spring shackle.

Figure 2 is a. longitudinal 'vertical section of the same.

Figure 3 is a perspective View of a metallic hanging-bar end.

Figure 4 is a longitudinal vertical section ofthe same.

FigureisV n. perspective View of a metallic hanging-iron socket.

Figure 7 is a perspective-view of a metallic'han'gingioni- .Figure 8 is a longitudinal section of the same.

Figure 11 is a vertical section, taken in the axis of the perch.

Figure I2 is a perspective View oi' a pole-crab; and

Figure 13 is a horizontal section of the same.

Similar letters indicate corresponding parts in the several figures of the same device.

The nature of our improvements consists in an improved spring-shackle, consisting of a three-sided link, and a bed-plate with a solid eye,` and formed to, receive an inverted axle-clip; the link and bed-plate being united by a wrought-iron bolt or rivet; in an improved hanging-bar end, so constructed as to receive the eye of the hanging iron in a cup or socket; in a4 hangingfiron cup,forrned to embrac'e and secure the wood of the hang-ing har,- yet allowing the usual wood finish on the bar-end; in a hollow metallic hanging bar; in axlc-yokesof malleable iron, combined with perch-stays of' wrought iron; in hollow metallic head-blocks, with the, perchcouplings, formed upon the l1eud-block; and in a pole-eral), formed with the lateral arms hollow, as also hollow pele-strep studs.

All the foregoing parts being formed of malleable iron, in order to give them their peculiar construction, und at much less cost than if formed of wrought iron in the usual manner.

In figs. 1 and 2, A represents the bod-plate, which is formed with a solid eye, through which passes the rivet a two holes I1 b for the'ends oi' the clip, and a stud, e, which serves to prevent lateral motion of the plate upon the bed.4 The link Il is formed three-sided, or with two flut sides, d fZ,yvunitcdat one end by the bar e, upon which bar the eyes of the spring are closed; at one end ofthe sides CZ el are eyesfor the rivet a. By thus forming the link three-sided, and combining it with the bed-plate by a rivet, the eyes of both are cast solid, instead of one being castopen in the usual clumsy manner. '.lhe har c is of a smaller diameter than the ends of sides d d, so that the projecting edge of the-sides curtains the eyes in the spring-ends. 'By forming the bedplate like a lclip-yoke, holes through either the hedor axle are avoided, thus leaving full'strength, at less cost than in the common method.

In figs. 3 and 4, A represents the end of the hanging bar, upon which is fitted a metallic cap or end, B, which cncloses the end of the bar in a socket, while straps extend a short distance upon the upper and under sides ofthe bar, and an end nish terminates the outer end of thesoclret. Where the hangingiron restsis a circular rim, a, surrounding the hole Z1, in which the hangingiron bolt is inserted. The cavity or cup thus formed .serves to receive the eye ofthe hanging har, as is plainly shown in fig. 6'.

In figs. 5 and 6, A represents the hanging-bar,'and B a metallic socket or saddle, which is formed to sit ast-ride of and prevent the splitting of the bar, asis shown, the two projections e c, enelo'sing and bearing against the sides of the bar, while two small perforated ears, e e, bear upon the top ofthe bar, and are the means of attaching the saddlethereto.4 d is a circular rim cast upon the saddle, and in the cup thus formed by the rim the downward-projecting eye, formed upon thehangingiron a, is inserted, resting upon a disk, of leather f, while a screw-bolt, b, passing through the eye ofthe hangingiron a, the bottom of the saddle B, andthe hanging bar A., serves to hold the hang'ing iron in pla-ce; the rim, serving to prevent all horizontal strain upon the bolt, or dange'r of rending the bar apart.

-In figs. 7 and 8, A represents a metallic hanging bar, formed hollow beneath, but presenting a continuous surface at the sides and top. Around the bolt holes bb aire formed circular rims a a., thus forming a cup, which' receives the eye ofthe hanging iron, as shown in tig. 6, for the purpose of relieving the hanging-bar bolt, which passes through holes b 6,'`ron1'lateral strain. c c are partitions, which unite lthe shell of the bar, and through the two central partitions the bolts d al pass, which secure the bar to spring e,.as' shown. `A bar 4thus formed can be graceful in appearance and but slighly heavier than of wood. v

In tig. 9, A represents a, malleable-iron axle-clip yoke, formed with the usual axle-step a, and the clipholes b Z1, while a short socket en extends at one end, in which is inserted the wrought-iron perch-stay d. This stay may be connected with the yoke by a male. and female-screw thread, or it may be laid in tlie mould, and the malleable iron cast upon it. i I

In gs. 10 and 11, A represents a metallic head-block, which is formed hollow in the same manner as the metallic hanging bar, shown in figs. 7 and 8, that is, it has a continuous surface at the sides and on the t0p, except at the spring-seat, there being a cavity, b, extending between the bolt-holes ff.of the fifth-wheel. Through the centre partition is the king-bolt hole (i, and on either side ofthe centre are'thin cross-bars, through which pass the spring-bolts in holes-e e. ais the perch-coupling, which is formed upon and is part of the head-block. B is the perch, and c is a wrought-iron plate, secured to the under sideof the "perch, and through which the king-bolt passes. VEitherlone or two of the perch-couplings may be formed upon the head-block, as the style of carriage may require, and while the strength of the head-block is greatly increased, the size and cost are greatly decreased. v

In figa 12 and 13, A represents the pole-crab, and B the end ofthe pole. IThe arms, a a, of the crab are formed hollow, as is plainly sho'wn in fig. 13, the holes c c passing entirely th'ro'ugh the arms, and the polestrap studs b b are also formed hollow in the same manner; the poles d d cxtending through the studs.

By thus forming the arms a a hollow, they are stronger than solid arms of the same weight; besides, as malleable iron is strongest next the surface, the arms have an increased surface of the tougher metal.; and Aby forming the studs b hollow, they are larger of the same'weight, and consequently cause less strain and wear upon the straps than smaller ones would.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. A. spring-shackle, formed with the bed-plate A and the threesided link. B, united/by the wrought-iron rivet a, substantially as described, and shown in figs. 1 and 2.

2. The stud c or its equivalent, formed upon the bed-plate, substantially as described, and shown in lig. 2.

3. The sides d d of link B, formed to extend beyond the bar e, Iand cover the springeye, substantially as -aud for the purposes specified.

4. VThe rim a, formed upon bar-end. B, for the reception of the hanging iron, substantially as described, and shown in figs. 3 and 4.

5. The socket B, formed to receive the hanging iron a, and the bar A, figs. 5 and 6, substantially as and for the purposes specified.

6. The hollow metallic hanging bar A, substantially as described, and shown in ligs. 7 and 8.

'i'. The rims a a, formed upon the` metallic hanging bar A, substantially as described, and shown in figs.- 7 and 8.

8. Combining the malleable-iron yoke A with the wroughtiron stay d, substantially as described, and shown in 9.

g9. The hollow metallic-head-block A, substantially as described, and shown gs. 10 and 11.

10. The perchcouplings a, formed upon the head-block A, substantially as described, and shown in figs. 10 and 11.

11. Forming the arms a a of the pole-crab hollow, substantially as described, and shown in'g. 13. 12. Forming the pole-strap studs 5?: hollow, substantially as described, and shown in figs. 12 and 13.
