To all whom it may come ma Be it known that 1, JOHN Ross, a citizen of the United States, and a resident oi the city and county of Philadelphia, State of Pennsylvania, have invented an Improvement in ltiggers Trucks, of which the follow lar upwardly ing is a specification. 1

My invention has reference to riggers trucks, and consists of certain improvements which are fully set forth inv the following specification, and shown in the accompanying drawings; which form apart thereo The object of-n y; invention is to provide a form of riggers truck which will permit of of its several parts as will adapt it for use under varied conditions, and which, moreover, will give it capacity for. manipulation that will enable the most diflicult loads to be handled with facility, whether in close quarters or on the read.

My invention consists otan up or l'rame ular portion, combined with a lower frame in which a central supporting wheel is journaled, said frame extending upward and concentric with the tubular portion of the upper frame.

i\ly invention further consists of the foregoing structure when als'oprovided with a' serew threaded connection between the ;tubular part ,of. the up er frame and the lower frame;whereby the orm'er may be adjusted upon the latter to diir'erent elevations.

My ini ention; also comprehends details of constritetion which, together with the featni emaboy-e s ec'iiied ,,will be better understood by; re eren'ce' to the drawings, in' \vhicl1';-"

l l l polar and provided with a downwardly extending tu threaded upon its interior. C is a art of the lower frame and is pro- :vided wit a cylindrical base C and a tubuextending part screw-threaded upon its exterior for adjustably engaging the tubular part B, as clearly shown in-Fig. 1. D is the other part of the lower frame-and is formed of a circular base with an upwarchcylindrica part fitting within part C, so as to be adjustable axially therein; ,The parts C and'D constitute the lower frame of the truck, and if desired may be secured together as a unit by means of bolts M, which extend through notches c in the flanges C and D. There may be many men of such notches in the flanges C than in the flange I), one or more being sufficient in the latter. By employing notches instead of holes, it is easier to remove the bolts when necessaryflshould the parts he I ammed.

F is the central sup orting w eel and is secui'ed to a shaftE w ich is journaled at (3 o to the under part of the frame D. The end of the shaft E may be mhde square for the attachment of a wrench or operating, 1e, er.

ular portion B preferablyscrew plate D provided I The wheel F extends well up into the tubular spacewithin the lower frame 1) so as to bring the top of the truck as possible. The upper frame A B may be adjusted to any ,'desired height above the wheel F by rotating it byj neans of a wrench shown in-Fig. top plate'or turn table upper frame A,- and may be; means of a downwardly centered by extending central Figure 1 is a sectional elevationjof a rigk, lug g at the center.

y indicated in Figs. 1 and and the r be rigidly secured. to-' P I my improved trucks; Flexi- 20 base D gether after proper adjustment has been made. When the vertical adjustment is being made, the bolts H must be removed, and the upper frame A B turned with the wrench shown in Fig. 10, after which the bolts H are replaced. 4 In Fig. 5, the screw adjustment between the parts B and O is omitted, and consequently. the parts A B C ,C are merged into a single frame A in which thelower frame D is j ournaled in precisely the same manner as said lower. frame is journaled in the 1 frame C C.. A

In the construction shown in Figs. 7-and 8,

the same general structure is followed, but in this case the axle of stead of being journaled in fixed bearings on the bottom of the frame D is extra frame D and springs L, of which four sets may be employed. I In this'mannerj'thetruck body is spring-supportedon the central roller F.

In some cases where ticles is required over long distances and where larger supporting wheels are necessary to sustain the greater load, the truck ma be formed as indicated. in Fig.v 9, in which t..1ere are two supporting wheels F F and a bearing structure arranged between them on. the

bottom of the lower frame D.

When the load is to .be conveyed in a straight path, the bolts M are employed; but

when thetravel is to be on a curve or in an 5 irregular course, then the bolts M are re-' moved andthe part D Df'is turned. to-change the axis of the roller to suit the direction of travel desired 40 details. may be modiiie lwithout departing from the spirit of the invention. Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is c 1..
