' i e/gym UNITED STATES PATENT EEIoE ANDREW W. MILLER AND JOHN O. MILLER, OF MORRISONVILLE, ILLINOIS.
IMPROVEMENT IN WAGON-SEATS:
Specification forming part of Letters Patent No 148,128, dated March 3, 1874; application filed January 19, 1874.
To all whom it may concern:
Be it known that we, ANDREW W. MILLER and JOHN C. MILLER, both of Morrisonville,
in the county of Christian and State of Illinois, have invented certain new and useful Improvements in VVagon-Seats 5 and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawin gs, which forni part of this specification.
Our invention relates to improvements on an invention for which Letters Patent were granted to John Gr. Armstrong and Jacob S. Armstrong, bearing date February 25, 1873, No. 136,123; and it consists in so arranging and constructing the hook-plate I that the said plate shall bear the upward and downward pressure of the compensating-rods, while it also forms the lookin g means, thereby dis pensing with a separate locking-piece; but that our invention may be fully understood we will describe thesame in detail.
Figure 1 represents a plan view of a block, D, with our improvements applied thereto. Fig. 2 represents a side view, and Fig. 3 a section through the lines x ai, Fi g. 1, in all of which the block is inverted.
D represents a block, suoli as described in the specification before referred to, to which the plates I, for receiving and holding the ends of the compensating-rods E are secured by screws or other suitable retaining means. The two ends of the compensating-rods E are `turned up, as shown at E', and the projections thus formed are, by preference, filed square on their front and rear faces. They may, however, be otherwise formed, if desired. I I represent our improved plates, which, in place of being formed flat over their whole surface, as described in the patent before referred to, are stamped, cast, or otherwise formed with channels or grooves i1 i2 and bearings i3, so constructed that when the parts are in position, as shown by the drawing, the channels or grooves i1 of the extended portion I1 shall rest upon the upper side of the compensating-rods E, while the channel or groove i2 'of the portion I2 a-nd the bearing i3 serve to retain the rods in position, and also to bear the downward pressure of the same. i4 are enlarged extensions of the grooves or channels i2, adapted to receive and allow of the free movement of the projections E of the rods E, the extent of such movement of the rods E in each direction being limited by the extensions i4.
By reason of the construction of the plate I, as described, the channels or recesses in the block D for the reception of the rods E are required to be cut only of a depth equal to half the thickness of said rods, thereby securing greater strength to said block. The weight or strain exerted on the rods E is wholly supported by the plate I. rIhe block D is entirely relieved, and the enlargement of the grooves therein, in which the rods E move, and the cutting away and consequent weakening of the block, are eectually prevented..
Having thus described our invention, what we claim, and desire to secure by Letters Patent, is
The combination, with the compensating` rods E and block I), of plates I, having ex-. tended portions I1, channels or grooves i1 i2, bearings i, and enlarged extended grooves i4, substantially as and for the purposes described.
In testimony that we claim the foregoing we have hereunto set our hands this 16th day of January, 1874.
ANDREW W. MILLER. JOHN O. MILLER. Witnesses:
CEARLEs M. DAVIS, GEORGE SPALMER.
