Beit known that i, GEORGE TiroMAs TURNER, a subject. of 'the .Dominion of Canada, residing et Hamilton, in the county 'of .VVentWorth, ,Prox'ince of; Ontario, and

.Dominion of Canada, have invented new and useful Improvements in Railroad Treck- 4Sca-les, of which the following is s speciiieation. e' r j The Ainvention relates t-'oycertnin improve ments inthe class of scales used on mii-roads )t .which the following advantages by Ineens,

are secured? 1) A more easy mode of ed- ','mitting repairs to be made. l

perfect and free oscillation of the piatform. (3) Greater stability of the ierers. (si) More,perfect adjustahility of'the rocker bearings. attain these ohjef'f'ts hy the mechanism' illustrated in theeccoinpenying drnwing, in 'winch- Figure l 1s e detaii rear View illustrating;

The old makes ot'- railroad scales had. s rigid bearing, .the dised'vmitage of which wais that when worn, the choir had to he re moved and repiaecd hy a, new one. con struct the rocker block :ind chair in. trete parts, but Aso, combine 'them that. i' een remorethe rocker block end insert s new one `Without removing the chair.

'It may further he said that with the oid method of construotinep the pivots cf the mein levers, they were very diiieult to re more when worn ont, to be replaced with new ones. 1

YVith my improved device, the levers can he taken out without my difiiculty or loss of time. and replaced easily and quickly, and at. the same time allow free oscillation to the platform, wht-ie the levers remain prachorizontni even hearing. y

It may still further he explained for greater olucidation, that the object of the split; steel arch 5,' is to allow the body of the hanger 1 3. to he made in one piece sind receive the sad "lle'block 1Q, at the upper end, ii immer miti 'LD Pvt/ewes U15 3, whereby the structure is further strength hy e icon 18,.

26, Fig. t5, represents one of the heee ticeily rigid, the pivots always having a. long to hung insidel of the arch, with a loop tobearing pin 1l, which shall be set at a right to the saddle block 12. This form of construction is intended to prevent the henger from stretching under a heavy strain sind to provide for the free oscillation of the sceie platform in ell directions, at the seme time keeping the individual saddle blocks 12, in posicion on the knife edges Witi nt rocking or swivelimr. it `will still further be observed that with the old method of construction the pivots of the moin levers, when worn out, were very iiilicnlt to remove, when they rezpiired to with neva ones, while with my c icticn, the uworn pivots can taken oni Without diiicnll'y or loss of time and re- 'ed easily end speedily while at the same they always have e, long horizontal bearing. ii' 'iesircd n stop 3G may be provided upon bs, ich plete 1G to limit the movement of the the recessed under faces of the arch castings to provide la rocking support for said castings upon the rocker blocks.

2. In a device of the character described, the combination of an arch casting 5, e hanger, a main lever, a pivot carried by said main lever and lying within said casting, a saddle block upon said piivot with which said hanger engages, a roo with said hanger and a member carried by said rocker block upon which said arch cas ing has rocking support. f

3. In a railway Scale, the'combination of e split arch casting 5, a hanger 13, made integral and adapted to hang inside the arch, a loop formed at the upper end, a, saddle block 12, made to pass through the loop, and

rest on a bearing pivot, an eye at the lower end of the hanger 13, a bearing plin 14,-made to pass through the eye at rlg t angles to the saddle block, for the pur ose of preventing the hanger from stretc ing under a heavy strain and allow 'free oscillation of a scale platform in all directions and keeping the individual saddle blocks in position on the bearingpivots without rocking or swiveling.
