Inventor Jae Tacke If m (ma W E M51815 3 seen that the lower ends of the belts and 3| derive motion from a motion transmitting shaft 32. This shaft, as brought out to advantage in Figure 6, is provided with

clutch pulleys

33 and 34, these fixedly keyed on the shaft. I now call attention to co-acting clutch members and 36 having brake bands, these telescoped into the

belt pulleys

33 and 34 in an obvious manner. Each of these

devices

35 and 36 is provided with a sleeve 31 which is splined on the shaft. The sleeve is provided to accommodate a yoke 38 on one side and a similar yoke 39 on the other. These yokes are operable by a shifter member 40 op-' eratively mounted in appropriate bearings or stands 4|. Incidentally, the shaft 32 is mounted for rotation in bearings 42 and said shaft is provided on its outer end with a pulley 43 which is driven by a power supply belt 44. The belt 44 is operated by way of a pulley 45 on a drive shaft 46 which receives motion from a belt 41 from an appropriate source.

From the description of the details so far given it will be seen that the power from an appropriate source received by way of belt 4'! drives drive shaft 46 and its pulley 45. Motion is transmitted from pulley 45 to pulley 43 which turns the driven special clutch equipped shaft. The shaft 32, the later clutch shaft is of the special construction shown in Figure 6 and therefore it is possible to shift the clutch means to rotate the shaft in either one direction or the other. By pushing the control lever 48 (see Figure 6) on its pivot 49 in a direction from, let us say, left. to right, the shifter 40 goes in the same direction and this, through the yoke 38 disengages the clutch member 35. At the same time it engages the clutch member 36 with the clutch pulley 34.

Moving the lever 48 and shifter rod 40 in the opposite direction from right to left the opposite resultis attained. That is to say, the clutch 36 is disengaged and the clutch 35 is engaged. These clutches are arranged so as to provide the desired forward and rearward drive motions for the carriage, the carriage taking its motion by way of the

gears

26 and 28 in mesh with each other and operated through the medium of shafts 25 and 21 receiving motion from the belts 30 and 3| (see Figure 3). Thus, we have so far covered the frame structure, the carriage. means and the shafts, pulleys, and clutch arrangements whereby the carriage may be shifted back and forth in relation to the frame structure.

It is desirable to employ the shiftable carriage as a reciprocatory table for holding and accommodating the Work. The work in the instant situation happens to be a railroad tie, this denoted by the numeral 50 in Figure-2 for example. Here we observe clamping devices suspended from 'the end portions of the carriage and engaged with the oppositeend portions of the tie. Each clamping device is the same and a description of one will suffice for both. Attention is therefore directed in particular to Figures 6 and 7 where it will be seen that the preferred construction embodies a yoke 5| properly hung from the carriage 20, a shaft 52 mounted in a bearing 53 on a hanger 54 carried by the carriage, said shaft having a crank handle 55 at its outer end. Mounted on the shaft is a pinion 56 which meshes with the teeth of a rack bar 51 slidably mounted in the yoke. The rack bar has a clamping head 58 on its inner end which engages the adjacent end f the tie.

I next call attention to the group of four rotary cutter units or devices mounted within the arranged in pairs.

confines of the frame structure and so positioned as to permit the log, tie or other work to be moved back and forth in relation thereto. It is desirable to simultaneously surface all four surfaces of the tie and any suitable tools or devices may be employed to accomplish this end. It is desirable however to employ rotary cutters and these are For instance in Figure 4 we see the

horizontal cutters

59 and 60. Then, in Figure 5 we see the pair of close complemental vertical cuters 6| and 62. same in construction and a description of one will suffice for all. The cutter includes a shaft 63 with a central polygonal portion 64 on which suitably arranged cutter blades 65 are mounted. The blades are independent and of toothed construction as shown for instance in Figures 11 and 12. The teeth are properly staggered and interrelated to produce the desired continuity in the cutting results. In addition, spacing collars 68 are provided and these are mounted in place by clamping nuts 61 and under the arrangement described it is possible to insert and remove cutter blades to adjust the total cutting surfaces to the width and thickness of the work to be acted on. Each shaft is provided with a power reception pulley 68. The end portions of the shaft are mounted in accommodation or adaptor blocks 69 having bolts 16 slidable in accommodation slots H provided therefor.

In Figure 5 we see the slots H in a transverse angle iron 12 embodied in the main frame structure. The slots at the top are in cross straps 13 also attached to the main frame structure by way of the top angle irons, this as is Obvious. In Figure 4 a horizontal angle iron 14 is provided and this coacts with a horizontal cross piece 15 at the top and the two

parts

14 and 15 support uprights or posts 16 in which the stated slots H for the bolts H! are provided. The posts are fixedly mounted between

parts

14 and 15. In addition, I provide cleats 11 wherever necessary to accommodate the shiftable blocks. The main thing is that each cutter device is the same, is bodily adjustable and is within itself adjustable so that the number of blades can be increased or diminished as conditions require. The cutter devices are in horizontal and vertical pairs and this makes it possible to adjust the pairs properly to accommodate variances in cross sectional width and thicknesses and also makes it possible to shave more-or-less off of top and bottom surfaces or side surfaces, as the case may be. Y

Coming now to the drive shaft again I call attention to the power take-off pulleys l1 and 78 which operate

motion transmission belts

19 and 80. The belts are arranged in pairs and the pulleys are sufiiciently large to handle same and the belts are obviously so arranged and twisted as to supply motion to co-acting pulleys 68 on the four rotary

surface cutter devices

59, 60, BI and 62 respectively.

The simple pulley, belt and shaft arrangement makes it possible to supply power from a single source to operate the drive shaft, to use the drive shaft for simultaneously operating the pulley equipped arrangement of four cutter devices. In addition the driven shaft 32 with its pulley arrangement and belts serves to supply the necessary motion for shifting the carriage back and forth. The carriage suspends thework and the work moves in proper relation between the sets or pairs of cutter devices and Each cutter is the I all surfaces of the work are thus simultaneously acted on and desired results accomplished.

A careful consideration of the foregoing description in conjunction with the invention as illustrated in the drawings will enable the reader to obtain a clear understanding and impression of the alleged features of merit and novelty sufiicient to clarify the construction of the invention as hereinafter claimed.

Minor changes in shape, size, materials and rearrangement of parts may be resorted to in actual practice so long as no departure is made from the invention as claimed.
