Be it known that I, EPIIRAIM Sornn, of the city, county, and State of New York, have invented anew and useful Improvement in Carriages; and I do hereby declare that the following is a full, clear, and egiact description thereof, which will enable others skilled in the art to make and use the same, reference bein l to the accompanying drawings, forming part of this specification, in which- Figure 1 represents a side elevatiom of my invention.

Figure 2 is a plan or'topview of the same. 7

. This invention relates to a new construction of the front support of carriages, and its object is to allow the application of 'c-springs to the front part of carriages, and also the strengthening of the top bed and upper transom-plate. l

The invention consists, first, in the use of a front perch, which is spcured or swivellfed to the back bar, and extends to the under side of the carriage, to which it is pivoted, thus doing away ,witlf'the through-perch, and still permitting the use of C-springs, which are fastened to the back bar and top bed, and from whichthe front end of the carriage-body is suspended. lleretofore C-springs could not be applied to the front part of carriages, the same being always supported by elliptic springs I The invention consists, second, in suspending the king-bolt from the upper transom-plate, and in forming it in one piece with the same, for the purpose of strengthening the top bed and upper transom-plate, which are heretofore considerably weakened, as they have to be perforated to admit the king-bolt.

A represents the front axle of a carriage, sup orted by the front wheels 13 B, and connected by means oi elliptic springs, O G, with the bottom bed D in the ordinary manner. The bottom bed D is, by means of the fifth-wheel E, connected with the top bed F as usual, and carries the lower transom-plate G, while the under side of the top bed F is strengthened by the upper transom-plate H. Iis the king-bolt, projecting from the under side of the upper transom-plate, and welded or cast to the same, so as to be suspended from it. i It fits through a socket, a, formed on the lower transom-plate, and carries a nut or pin, 6, on its lower end in the ordinary manner. In the upper transom-plate is arranged an oil-hole, e, as shown in fig. 3,120 conduct oil to the socket a. It will be seen that the top bed and upper transom-plate, as they are not perforated to receive the king-bolt, will be considerably stronger than usual, and that they, as well as the bed-plate d, resting upon the top bed F, can consequently be made lighter and of better appearance than usual. J is the back bar, secured upon the fifth-wheel in the ordinary or in any suitable rnanner. K is the front perch. The same is an iron or other bar, swivelled in a socket, e, which projects from the back of the top bed F,and passing through a box, f, which is secured upon the back bar J, as shown in figs. 2 and 3. The back of the pereh is bifurcated, as shown in fig. 2, and each of the back ends is pivoted to cars, 5/ g, projecting from the under side of the carriage-body L. The perch reaches as far back as may be desired, but is not connected with the rear perch, which extends forward from the rear axle.

When a front perch like the above is used, the front part of the carriage-body may be suspended from c-springs, M M,, which are secured upon the back bar and top bed, or either. The carriage-body will then be suspended in a very elastic manner by means of straps, it, from the springs M, and will be prevented from jcrk= ing. By using the swivelled perch, the carriage-body will be retained in a level position, even if the wheels on one side stand or move on a higher grade than those on the othegside. V

Instead of bifureating the rear part of the porch, the same may be provided with a cross-bar at or near its end, whereby its shape will be made to resemble the letter T, as shown by red lines in fig. 2. Both ends of the cross-bar are then pivoted to the cars g.

The perch can also be firmly secured to the top bed and back bar, instead of being swivcllcdi In that case the carriage will not swing sideways, but will still more easier than with the ordinary perch now used.

l'laving thus described my invention, I claim as new, and desire to secure by Letters Patent- 1. The front perch lQseeured or swivcllcd to the top bed and back bar, or either, and pivoted with its rear and described.

end or ends to ears 9 g, which project from the under side of the carriage-body, suhstantielly as herein shown 2. The combination of the front perch K, when the same is made and operating substantiallyns herein shown and described, with the ears g, back bar J, top bed F, and c-sp rings M, all made and operating substnntially'as set forth.

3. The king-bolt I, when formed on and suspended from the under side of the upper transom-plate, substantially as herein shown and described. I

4. The oil-hole c in the upper transom-plate, when arranged as described, to convey oil to the king-bolt, which is suspended from and formed on the upper transom-plate, substantially as herein shown and described.
