IMPROVEMENT IN KEY-BoLT CONNECTIONS` FOR CARJRVUCKS.
'Specification forming part of Letters Patent No. 49,163, dated August l, 1865.
Figure 1 is a vertical transverse section l through a railroadftruck having my invention applied to it. Figs. 2, 43, and 4 are modifications of the key-bolt connection of Fig. 1. Figs. 5, 6, and 7 are enlarged sectional views of the key/bolt connections and their elastic buffers.
Similar letters of reference indicate corresponding parts in the several figures.
The object of this invention is to greatly di minish the concussions and shocks to the truckframes, iianges of the wheels, and rails by affording an elastic resistance in a horizontal direction at thekey-bolt connections ot' the carriages with the trucks, so that While there will be less sudden strain upon the keybolts there will be less destruction and danger of breakage to the rolling stock, and also to the Tails, than hitherto, as will be hereinafter described.
To enable others skilled in the art to understand my invention, I will describe its construction and opera-tion. l
My invention consists in surrounding the key-bolts a with blocks of india-rubber or other elastic substance which may be found to answer the desired purpose, and confining these blocks within sockets or boxes which are seated either into the cross-beams ofthe truck frames, or in the transoms of the car-body, or
in both of these beams, as may sirable.
In theaccompanying drawings I haverepresented several modes of carrying out my inbe found de vention, all of which embody the same general principle-viz., affording lateral, diagonal, or
ing end is inserted into a cylindrical block, b, L of india-rubber, which block is `coniined ,in l place within a anged cup, c, asshown in Fig."
1. The flanged cup c is recessed into the cross,` beam B ot' the truck-frame C, so as to leaveits iian ge exposed on top of said beam,` to serve as a bearing for the collar or ange a of the bolt i a. The bottom ot' the cup cis perforated to admit the bolt a through it, and this perforation should be of suihcient diameter, if the bolt does pass through it, to allow the bolt to have a free horizontal play, resisted onlyiby the elastic substance b, care being takenfthat a sufcient interior rim is left in the bottom of the cup t0 support and confine the rubber, as shown in Fig. 1 and elsewhere in the drawp ings.
In Fig. 2 the same form ,of bolt is used as described in Fig. 1; but in thisinoditication t the bolt is not secured to the transom, but its l upper end is introduced into an indiarnbber block, e, which is compressed within an inverted cup, d, both otwhich` are `constructed and arranged in the transom substantially as those in the truck in Fig. 1. Thuseach end 1 of this bolt being inserted into an india-rubber block, and its m'otionsbeing otherwise free, it operates with a double elastic action.
Fig. 3 shows a modiiication in which the common key-bolt g `is used. This inode con-f sists in the employment of flanged tubesh It', through which the bolt g passes. `The iianged tube l1l is inserted into the transom A and suitably secured thereto, and the iiangedtube h is inserted into the rubber block b, so that while it is free to `yield with the rubber its flange will rest upon the flange ot' the cup c and afford a solid bcarn g and supportfor the f transom A. l
By making the key-bolts sufficiently large to avoid a cutting action upon the rubber, the
iianged tube h may be dispensed with, as shown in Fig. 4; and cast-iron bolts may in some cases be substituted for wrought-iron? ones with safety. Inthis niodication and in that of Fig. 3 the bolts may be arranged in the` transom in any usual or convenient manner. In these modifications it will be seen thatI have only carried out the principle of my in` vention and presented it in new forms and z arrangements.
When two buffers or rubber blocks are used` one for the transom andthe other for the crossbearn of the truckthe elasticity ofthe con? shown in the drawings, if desired, the only material changes required being the introduction of an auxiliary rubber block and socketcup into the transonn The bolts or flanged tubes, as the case may be, may pass entirely through the sockets c and d, as shown in Figs. l2, 3, 4, and 6, or may be adjusted to terminate Within the sockets, as tshown in Figs. 1 and 7, as may be preferred, care being taken that they have in botn cases roper horizontal space to yield with the rub- It is not intended by my invention to provide an elastic resistance to any vertical rnoven ment of the car-body or key-bolt. My invention is intended to guard against injury to the rolling stock and thc rails, in consequence of lateral, diagonal, or 'longitudinal thrust, by employing an elastic substance iu such manner as to deaden or yield to the concussions.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
l. The elastic key-bolt connection for railway-carriages, when arranged and applied to operate against lateral or other horizontal impulse, substantially as described.
2. Surrounding the pivot or key-bolt connections with india-rubber or other elastic substance conflned Within metallic cups or boxes in such manner as to admit .of a horizontal motion of' said key-bolt, but no vertical motion, substantially as described.
