a corporation of Delaware Application June 25, 1934, Serial No. 73am 8 Claims. (Cl. 144- 208) The present invention relates totimber supporting carriages for rossing machines or the like. In rossing bark from large logs which are used in the production of telephone poles and the like, and machining the surface of the same, it is necessary to provide some means of support for the overhanging portions of the log, both as itis fed to and from the rossing machine. This support must travel with the log and must also permit the log to revolve. as it passes through the machine.

An object of improved travelling supporting means in connec tion with a rossing orsimilar machine, for receiving and supporting the overhanging portion of a log as it is fed from the machine.

Another object is to provide such a support embodying log-supporting rollers which will permit rotation of the log and which are tiltably mount ed on a supporting truck, whereby the log may be readily discharged to one side after it has passed through the rossing machine. 1

Other objects and advantages of the invention will become apparent during the course of the following detailed description of the invention when read in conjunction with the accompany? ing drawings, in which,

Fig. 1 is a side elevation showing a rossing machine in outline and the improved log-supporting means in operative position withrespect thereto,

Fig. 2 is an end elevation of'the log-supporting means, the dotted lines showing the supporting rollers in log-discharging position,

Fig. 3 is a side elevation of the log-supporting means, and i Fig. 4'is a perspective viewof one of the skid bars.

Referring more'particularly to the drawings, 5 indicates a track which extends in both direc tions from the rossing machine 6 and upon which tal channel irons 8 and 9 supported by the axles ll] of the flanged wheels II. A pair of upright channel members l2 and I3 are mounted in spaced relation on the channel iron 8 and a pair of upright channel members l4 and I5, one opposite each of the members I2 and I3, are mounted I on the channel iron 9, The channel members i2,

I4 and l3, l5 are braced and secured to the channel irons 8 and 9 by transversely extending this invention is to provide an angle irons l6 and [1, respectively, which are welded or otherwise secured to both the horizontal and upright channel members. The channel members [2 and it are additionally braced by a gusset plate l8 welded to the same. '5

A pair of spaced transversely extending. bars I9 and 2i are mounted between the upright chan-.

nels ELM-and l3, l5, respectively. The bars are secured to the channel members, as by welding,

and each is provided with a laterally inclined up- 10 peredge 2! extending from adjacent the center to one side of thecar-riage. The bars extend be:

yond the uprights l2and l3 at that side so that the slanting surfaces 2! provide a skidway over-1 hanging the side of the carriage. 5 I A tilting leg-cradle 22 is mounted between and supportedby the bars 19 and consists of a pair of transversely disposed

rollers

23, and 24 jour nalledon axles Z5 between a pairof approximate ly triangular plates 25. The plates 26 are'DiVQ'fl" 2Q ally mounted upon a spindle 2'5. extending through openings 28 (see Fig. 4.) in the bars l9, and 2D. The rollers .23 and 24 are positioned at opposite sides of the spindle 2.1 and are preferably equally spaced therefrom, so that the load supl flrted between the rollers will be balanced about th Pi Ob provided by said spindle.

The axles 25 and spindle 21 are held in position against axial movement by small locking plates 29 which engage a groove or the like adan jacent the ends thereof.

One corner of each of the plates 26 extends laterally beyond the uprights M and i5 and a handle 39, shown as a metal sleeve, is mounted between the extendin DQItiQnshpon a bolt 3!. A stop 32 which may be formed of a pifice of s rapiron mounted betwe n the. u ri hts l a d I5 serves to limit rotary movement of the, cradle 22 in one direction and o po i ion it fo e reception of a lockin pin 33 wh h pa se throu h alined openings in the upri ht I4 and I5 and plates 26 to lock the cradle in norma p ition with he axes of the rollers 23 and .24 n su stantially the same horizontal plane asshown in full lines in Fig. 2. A stop 34 which may be a wooden block mounted between the angle irons .16 is providedior en ag men by h oller 24.

to limit further tilting movement of the cradle when the upper surface of said roller has passed b low the plan f he skidway provided, by th o0 inclined surfaces 3|.

In the operation of the device, the cradle 22 is normally locked in the full line position of Fi .2 by h lockinsp n 33 and a the 10s l aves.

the rossing machine, the overhan end is supported in the crotch of the rollers 23 and 2d, thus permiting turning of the log during the feeding and rossing operation. After the log has completely cleared the rossing machine and is to be unloaded from the truck, the operator removes the locking pin 33 and lifts the handle 39. This operation results in rocking of the cradle about the pivot 2? to the dotted line position shown in Fig. 2 and lowers the log onto the slanting surfaces 2| of the bars ES. The rocking of the cradle in this manner imparts an initial transverse movement to the log and as it strikes the skids 2! it slides or rolls off to the side of the carriage, by gravity.

After the log has been discharged from the carriage, the operator pulls the cradle back to the normal position with the lower surfaces of the plates 26 engaging the stop 30 and inserts the locking pin, and the carriage is then ready for the reception of another timber from the rossing machine. It will be seen that due to the balancing of the load at all times, the operator can quickly discharge the timbers ,fromthe truck with comparatively little efiort, and delays in the rossing operation occasioned by failure to get the carriage back promptly into receiving position for the next timber are avoided.

While the carriage has been shown as discharging to one side only, it will be understood that it could be made to discharge to either side; also that modifications and changes in details may be resorted to without departing from the spirit of the'invention.

Also, it will be obvious that while the invention isespecially applicable to the handling of logs, timbers and the like, it is equally useful in the supporting and discharging of any long, heavy articles, whether of wood, metal or other materials. Y

I claim:
