To all whom 'it may concern:

Be it known that I, WILLIAM H. Minna, a citizen of the United States, residing in Chicago ,'in the zcounty of Cook and State of Illinols, have invented a new and useful Im rovcment in Bolsters for Cars of other Ve -cles, of which the following is a specication.

My invention relates to holsters for cars or other vehicles, and especially to those of s truss construction, comprising e. compres sion embersnd a tension member and an intervening strut,

Hemtofore, the holsters of the kind or class to which my invention relates, have ordinarily had the ends of the ilatfroller steel tension member folded over the ends of the compression members; and in order to secure the parte together under the proper tension so as to prevent bending or bowing of the compression member, it has been necessary to employ an expensive and special construction of machine b means of which the ends of the flat stee tension member could be folded over the ends of the comression member while the tension member 1s heated to s. high temperature in order that thesubsequent shrinkage of the metal may 've the parts their requisite or close tension` t with each other; And in case of breakage or other serious injury to either the com-4 pression member or tension member .or other part it has heretofore been necessary-to send the bolster back to the factory where it was made, 'or where the special machine for uniting the compression and tension members is located, `thus rendering repairs extremely diilicult, troublesome and expensive and frequently causin much car and trafiie dela The object o m .invention is to' provi e sn improved cons ruction of trussed rolled steel bolster, by means ofewhich these diffi- Bpeccation of Letters Patent.

. central strut through cultiesl may be overcome, and the repairing of the bolster by substitution of a new compression member or new tension member, a new central strut or other part enabled to be made at any ordinary railway car shop, and the bolster will be made of an extremely strong and durable construction.

My invention consists in the means I employ to prscticall accomplish this object or result as herein s own and described.

In the accompanying drawing forming a part of this specification, Figure l is a central PatentcdJune 29, 1909.

Figi-s. 4 and 5 are detail views illustrating modi cations.

In the drawing, A represents aportion of a car truck frame, B the compression member of the bolster, C the tension member4 thereof, D one of the anglo connecting blocks, E the which the king bolt extends, F the bolster springs, G the lower spring seat and H the s rin cap or follower between the springs an the cls ter.

Each of the angle blocks D is dprovided with o. flat inclined seat or portion adapted to receive and t flat against the upwardllgv inclined end b of the compression member and also with a shoulder d against which the extreme end b' of the compression member B directly and snugly abuts. The end `b oi the compression mem er is securely, firmly ond rigidly secured to the seat portion d of thie'ang e block D by rivets b. The an le connecting block is also provided wit an inwardly extending shank portion d furnished with u right strengthening ribs d on the upper si:l e, and4 provided at its extreme yend with transverse shoulder-sd*4 and transverse recess d to receive the gib.' or shoulder C* of the tension member C. 'Ehe shank dis firmly and rigidly secured to the tension member C by rivets c, the interenggmg gibs or shoulders on the tension member and connecting block serving in part to relieve the rivets from shearing strain.

The angle block D is also provided on its lower side with s horizontal cap seat dl to receive the horizon cap or bearing H of the spri F. e cap seat d' is preferably surroun ed by a marginal Hangs d' to embrace the edges of the cap Hj.

By this improved construction, either the compression member, member, the
