Letters Patent No. 103,692, dated .May `31, 1870.

IMPROVEMENT IN RAILWAY-RAIL CHAIR.

Ihe Schedule referred to in these Lettera Patent and making part of the same To all whom it may concern:

Be it known that I, JOHN S. WEIMER, of Pleasant Hill, in the county of Miami and State of Ohio, have invented a new and improved Railroad Chair; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing and to t-he letters of reference marked thereon.

. Drawing.

Figure l is a perspective view of my improved railroad chair.

Figure 2 is a side elevation, with the chair supporting two rails. h

Figure 3 is a transverse vertical section, taken on a' line, x'a:, of iig. 2.

Similar' letters of reference denote like parts in each of the figures.

This invention relates to au improved railroad chair; and

It consists in supporting the ends of the line-railsI with a chair constructed of two pieces of Trails'of suitable length, their upper surfaces being so made as to receive and hold in position the line rails offt-he track, and allow them to expand or contract during cold or warm weather, all of which will be more fully designated and set forth in the following-specilicatiolf and claim.

To enable others skilled in the art to which my invention relates to make and apply the same, I will proceed to describe its construction'and operation.

In the annexed drawing, forming a part of this specification- A represent thc line rails of a track constructed in the common T-form.

B B refer to my improved chair, which is made of two pieces of rails havinga dat upper surface, b b, and longitudinal, projections ce', which, when said rails are taken together, form a grooved bed, within or upon which the ends of the' rails A A are to rest.

I) Dare flanges, which are to be made sufficientlydurable to hold the ends oi" the line rails securely in position.

The rails B B rest upon t-ies E E, which are laid a sulcient depth below the others to allow my im proved chair to be laid under and lengthwise with the line rails A A. i

F F are bolts, which pass through rails B B', and are secured by screw-nuts j' f.

B has a groove, e, adapted toalip, e, on rail B, this giving an additional security to the chair.

G G represent the ordina-ry ties of the track.

By my improved chair the rails of the track are firmly and evenly matched, the raveling of the rails, when struck by the wheels of the cars when their surfaces are uneven, is prevented, and a more easy and uniform motion to the`cars is secured.

Having thus described my invention,

WIiat'I'claim as new, and desire to secure by Letters/Patent of the United States, is

i A'railway chair, formed of the two T-piece rails B B', they having shoulders b l, central cheeks or flanges `I) D', -upon each sideof which are formed longitudi nel ridges or projections c c', said rails being secured by bolts Illfand meshing together at their .lower edges by means of the groove e and lip e', as shown and described.
