IMP'RQVEMENT IN cARRlVAeg-Top moines. i

vSpecification forming part of Letters Patent No. 196,477, dated October 23, 1877; application filed `March 2 1, 1877. v

To all whom. t may 'concern Boston, "Statecf Massachusetts, have invented .Improvemets .11,1 Gefriaeeorona 0f vhih the following is .a vspecification:

details or 4constituent parts of top'carriageirons fof the kind, 'similar to that forwhilch. Letters Patent of the United States were granted to me on the V18th day of November,

1873, and accompanying parts; and the-inventlon consists in the improved arrangement of the hollow bosses by which the rail is lboltedV in position; in the construction of the rail to receive thearrn-staygfin bosses or seats for the curtain-knobs formed upon the rail; in a sockj .acted standard 'formed to be securedtothe rail-holders, to receive the rail throughgsu'ch socket, and to support the'backboard; in a socket formed longitudinally in the cast metal, either in theaxis of the'rail proper, Aor in the top-'joint arni, to receive the wroughtiron exvtension of the rail; in a seatformec'l 1in the top- -joint arm, to receive a bow cushion or buffer; in a seat fornled'in said arm to receive a seg- ,nient -or arc of wood, in forming -said arm with two seats therein-Lone abovelfor an 1elastic buffer, and Vone below fora sectionlof woodyin a socketed iron frame removable from said'- arin, andprovidedwith seats for the wood andbufer; ina stopwasher and slotted collar, by

which the washer is -held from rotation4 when tilted yuponfby *the topi joints, all Aas will, by V the aid of the accompanying drawings, be

.herein fully described.

Fig. 8 is a 'section`si1nilar 'to Fig. 7, except that it shows the wrought-iron extension inserted in a socket formed longitudinally in the cast-metal rail at tliejunction of thetop-joint arm.

Through the holes s (formed Vini the standards) the rail:

passes. These standards, formed of malleable iron, have a 1iiattened and widened portion at their upperV end, as shown in Fig. 17, `which is` let'into the bachboard iiush with itsback side, and is secured byserews.1 Its lower end ter- Ying it into the standard, as shown in Fig. 6, or

byinserting itin a smooth-bored hole and se-J curing it by `a rivet.

*l @is thearni-stay, the front end ofl which is` seeuredby riveting, ora screw-mitin the hole in boss Informed in raila, between therbolts Y j,-and like the bosses y.k `The upper end of this Y stay turns z inwardly, and is secured to the s baclrboard f in the usuali manner. i. The bosses L present a circular area in plane, cfa size to 1 receive the base of knobsa, which thus are assured a firm. seat, with greatly-diminished i Y strain upon the pivots-,ha result unattainable Y i when 1the rail iis formed; with anoval, crosssection in its entire length, as heretofore.

- The cross section of :arm I), between :coli lars ai, or shoulders, and-,"a2.,1is shown in Fig. l 3. In this arni is formed the seat for the elas i :tic buffer a, (shown in said iigure,) and the cirele is completed by the wood e, to @which the kleather covering e may be nailed. A circular collar or shoulders, el, is formed uponthe rail, andifrom it the `armfb extends tothe circular collar ker 'shoulders e, formed upon the arm,

f1 emi @which the pivot a extends, and uponV which it is formed. i In Figs.` 10,1 i111, l2,1 this` arm is shown with a cross-section varied from that in Fig. 3, the cross-section of the wood o being an arc of a circle, and the buffer u of such form as may be readily cut from a sheet of proper material, the short spurs, b', formed on the arm serving to hold the wood in position. Fig. 13 also shows a modification of this arm, in that a central passage through the metal admits'a small rail-arm to extend through it, while the buifer u has the saine form as in Fig. 12; but the wood has a longitudinal groove formed in its plane, to receive the projection of the socket, as also to hold the wood in place. In Fig. 4, a cored hole, c', is shown, which is arranged longitudinally in rail a, and at right angles to the hole cored in arm b, for the reception of backrail c. This hole c' is for the purpose of strengthening the rail at this point by preventing shrinks in the metal. The collar a2, or shoulder, which is formed upon arm b has a space cut away from its lower edge, as shown in Fig. 2, and marked fr. The

cutting away of this space serves the double purposeof rendering the pivot n stronger, and

serves as a recess in which the stud or stop q,

formed on the washer d', (shown in Figs. 1, 15, 16,) engages, and thereby prevents the rotation of this washer by the action of the topjoint eyes, when the top is raised or lowered.

This washer protects the leather covering z from wear and abrasion by the action of the top-joints; `The :cap-nuts Vwww :are threaded upon theendsor pivots a af of therail, in the; f i

usualmanner., forming; the inV relation to theV axis` of the` raile,and1 also.

a greater uniformity of the bulk ofzinetal is thereby secured, Vand a longer Vline of subdi-` vision is obtained.
