IMPROVEMENT iN lRQN TENDER-FRAME To all 'whom it 41mg/ Gfmcern:

vBe it known that l., BENJAMIN y i. HEALEY, ot' Providence, in the county of Providence and State of Rhoileylsland, have invented a nrw and usei'ul improvement in Iron Tender or Car Frame; and .l do he'reby declare that the following is a full, clear, and exaet description thereof, whirh will-enablebthol skilled ,in the art to ineke and use the saine, referentie beinghad to the acoolnpanying` drawing 4ii'irniing part of this specification.

The traine ot' tenders i'or locomotives and for various kinds ot' railway oars have bei'ore'lny invention been constructed of iron. Such t'rzu'nrs have, however, lheretofore been invariably inade l'roin boilerqlilate iron, and inode up ot' two strips placed par: llel with cach other7 and united by means of rivets at one ot' their edges to a third strip placed at right- '.rngles to both .tho others, the edges ot' the third strip being' turned over to forni ianges to hold the rivets which unite it to the other two plates. [ron beams and girders used in architectural work harve been and are constructed in the way to which l reti-r. ihe amount ot' labor required to make a irnine i'roni bars so made up necessarily very great, and the oost'of construct-ion from this faut and from the weight of metal required to give the traino sntlicientstrength is proliiortionately large. My

` invention residesin the employment., for the ln'ain beams of suoli frames, ot' ironyhieh has been rolled into the form of hollow bars of three, sides, two of whieh are parallel, and which description of bar is commonly known as channeliron, whereby 1 :un enabled to produce e traine with much less weight ot' niet-al, l etrid et the labor and expense incident to nniking the i'ranie t'rloni'bars formed in the old way, and grratly inereasetits streng-th and durability.

A are the sido bars ot the traine, which are l made of ehal'm'el-iron, as shown in. Fig. 2. 'L he side bursA-are bent at the corners ol" the tru-me, and. extend inward at right angle-s to forni the Specification forming part of Letters Potent No. 103,978, dated June 7, LSTO; reissue No. 4,661, dated December 5, 187i.

ends oi' the irnne. The ends of the brsA meet at the center ot' the ends oi' the frame, and are secured in plaee by a short. bar, u', placed in the channel ot' the bars A, overlapping their joint,A

and-is securely bolted or riveted to the body lof the ends ot' the said bars, as shown in Fig. 1. B nre the niiddle longitudinal bars, which are also made oi' channel-iron, placed with their channels toward tho channels ot the outer bars A. The longitndinai bars A and B upon each side of the traine are connected to each other and strengthened bythe V-shnped braces U, each pair ot'which is bolted or riveted to each other at their middle parts, and their ends are pinned in the channels ol' the bars A .B and bolted or riveted to the body ot' the seid bars'A, B. Three (more or less) pairs ot' braces, C, ere used uponeach side, :recording tothe size ofthe l'ralne. The ends ofjthebirs are connected with the bars A at` the ends ot t traine by the plates l), which plates D are se?? ourely lioited .or riveted to the bars A ani] B, as shown in Figs. l and 5, said bolts or rivets passing through the tiangos ot' the bars A B.. The

hars Bare also oonneeted to each other et dift'erent points ot their length bythe piates E and F, bolted or riveted to the upper or lower sides of the said bars. The plates l) hTFnot only strengthen the traine, but also serve as supports for the attaehnients ot' the rnnning-genr/and body of the ear.

Having thus described my invention, I Wish it .understood that although itis necessary to brace the trame thoroughly l do not make the number and hind ot' braces U D E F or their arrangement essentiai to the employment oi' the invention.

'Furtherinore7 l'declare that ,l do not olaim mak-- in g a tender or oar l'ranie ot'firon bars formed from riveted plates; but

That i de elaini as my invention, and desire to secure by Letters Patent, is

The iin proved trarne for railway carriages, consisting ol' the parallel longitudinal exterior and interior bars ot' channeled iron, united. by end hars and braced laterally at right and oblique angles, substantially as and for the purposes speeitied.
