To all whom it may concern:

Be it known that I, BASIL MAcon, of the borough of Manhattan of the city of New of logs. For such work, it is common practice to provide each car truck with a long trans verse member, known as the bunk, supported above the car trucks upon the bolster and adapted to receive the ends of the logs; and two such trucks, when thus joined together by a load of logs, constitute a single ,car or element of the logging train and require no other connection between them than the logs themselves. In these logging trains, it is desirable that the pull upon the draftrigging of the trucks be communicated as directly as possible to the load in order to take as much of the draft strain as possible from the' trucks themselves. In the present case,

' the draft rigging is connected directly to the bunk and, in accordance with the present lmprovements, is pivoted thereto so that as the logging train takes a curve the two that the ends of these'rods whereby,

bunks of each coiiperating pair of bunks may remain parallel while the draft rigging on each truck may swerve sufficiently to preserve its alinement with the cooperating draft rigging and the connecting rod between the two. Moreover, in accordance with the present improvements, the ends of a connecting rod are received in relatively ong connecting heads upon the trucks so are brought as of the car trucks as possible, as the train is backed there will be the less tendency to push. the connecting rodsand. the cotiperating draft bars out of alinement.

Another feature of the improvements consists in providing an underhung member near the center upon the frame of the truck which member 'the track whenever the truck jumps the is so arranged above the rails as to support the frame thereupon whenever the wheels accidentally leave the track. This member, moreover, is placed low enough to prevent the wheels from striking the ties and thereby rom running over the tics and destroying forming I York, in the county and State of New York,

improvements which need track, the truck, in such a sase, sliding upon the track through the medium of said memher which overhangs the track on each side.

Still another feature of the improvement consists in the provision of stakes pivoted upon each side of the bunk to retain the load and means on each side of the bunk to control the stake on the other side, whereby the load may be dropped on either side of the track by workmen stationed upon the other side of the track. v

The improvements referred to will now be described in connection with the drawings and together with other features of not be particularly alluded to at this point.

In the drawings: Figure 1 is a plan view of a truck embodymg the improvements. Fig. 2 'is a view in transverse section, the plane of section being indicated by the line 2-2 Fig. 3 is a side View. -Fig. 4 is a detail view in plan of one end of the draft bar.

in Fig. 1.

Fig. 5 is aview' in longitudinal section; Fig. 6 is a View on a smaller scale illustrating the application of the trucks to the carrying of logs.- Figs. 7 and 8 are detail views of means for controlling the stakes upon the ends of the bunks. I

The frame of the truck will be seen to consist of the two side members a provided with suitable bearings b to receive the axles c of the wheels (Z,'andtransverse members 6 connecting the ends of the side members which extend, at each end, beyond the wheels. In addition to these side and transverse members, the frame includes diagonal bracing members f each of which extends from the center of one of the transverse members to a point near the center of one ofthe side members. The bolster g is "spring supported as usual upon the spring-carrying plank h whichextends transversely across the frame. In the present case, this plank is arranged underneath the frame, being of a suflicient length to overlie the track on'each side, and is hung low enough so that when the wheels leave the track it will strike the track before the wheels have dropped to the ties, thus leaving the frame supported upon the track and preventing the wheels from running over the ties and tearing up the tracks. In order to limit the sidewise motion of the truck when it is thus supported through the medium of this elongated plank, the latter intermediate its ends the center of the bunk is a cylindrical bracket which is rigidly secured to the bunk and forms a pivot for the attachment of the draft rigging p which is arranged between the bunk and the bolster. A fastening pin or bolt 7* is passed through the bunk, cylindrical bracket; draft rigging, bolster and spring plank and fastens all of these parts together.

The draft rigging is provided with connecting heads 8 which work against the draft rigging springs 25 as usual. The heads, however, as will be seen, are considerably'elongated so that the ends 'of the connecting rods 24 may be carried well in toward the center of the truck where they are secured through the medium of connecting pins 21. Thus will the alinement of any two cotiperating draft bars and their connecting rod be preserved whether the train is moving forward or backward. On each side of the bunk stakes w for retaining the load are pivoted, the pivots be being beneath the center of gravity of these stakes when they are in their normal positions, so that when released the stakes will drop automatically. The stakes are retained in their normal positions through the medium of a chain or cable g, each such chain or cable being connected to means upon the opposite side for raising the corresponding stake into operative position. Such means may consist, for instance, of a roller 2 to wind the cable on and a ratchet j secured to the roller and controlled by a pawl 9. (Figs. 2, 7 and 8-). The cable may be wound up by a key inserted into one end of the roller .2 (Fig. 2) and by moving the pawl handle to the left in Fig. 2, the pawl is disengaged from the ratchet and the stakeupon the opposite'side drops by its own wei ht. A loose arm a is provided upon'the ro ler 2 and has a shoulder 2 which fits into a notch Q2 on the pawl g in order to hold the pawl in a particular position and to prevent the ratchet j and roller 2 from moving in either direction.

In Fig. 6, it will. be seen what the relative arrangement ofthe arts is in a logging train made up of the improved trucks, when such train takes a curve. The logs are indicated in broken lines, being stretched across @35 the respective bunks of cooperating trucks.

The forward t-ruclrof each pair of trucks is connected to the rear truck of the pair in advance through the medium of a' connecting rod u. The two connecting rods shown in Fig. 6 are relatively somewhat shorter than might be employed in actual practice but they sut icieut-ly illustrate the point to be brought out inthisfigure. Such point is the connected by the rods a, and it will be seen that the pull upon the forward trucks in each case is applied at the center of the corresponding bunk andthat said pull is in the direction in which't-he track extends at that point and not necessarily normal to the position of the bunk, the latter, as is obvious, being always parallel to the cotlper'ating bunk. 4

I claim as my invention:

1. The combination with the truck frame, bolster and wheels, of the spring-carrying plank elongated so as to extendbeyond the wheels on each side and projecting below the truck frame to a level less than the height'of the track from the wheel base.

2. The combination with the truck frame, bolster and wheels, of the spring-carry ng plank'elongated so as to extend beyond the wheels on each side and projecting below the truck frame to a level less than the height of the track from the wheel base, and means upon the underside of said spring-carrying plank to limit the lateral movement of the truck when supported n n the rails through the medium of said springcarrying plank.

- 3. In acar truck, the combination of a bunk to receive the load, and draft rigging pivoted thereto.

4. In a car truck, the combination of a long transverse member to receive the load, a downwardly projecting member secured to the central part of said transverse member, and draft rigging pivoted to said down wardly projecting member.
