Specification of Letters Patent. Application filed December 23, 1907. Serial No. 407,873.

Patented.Jan. 5, 1909.

To all whom itmay concernp 4 Be it known that I, FRANK V. CARMAN, a' citizen of the United States, residing at Oakland, in the county of Alameda and State of of the filling being to restore the holding capacity of the ties for fresh spikes or redriving of the old ones.

The object of my invention is to provide a simple and effective machine for rapidly and accnratelyjcu'tting and pointing groups or clusters ofisaid plugs in the ends of blocks of i'wood', and then dismembering the groups and collecting the severed plugs.

My invention consists in the novel construction pf parts and intheir-arrangement and combination, as I shall hereinafter fully? describe, by reference to the accompanying drawings in which Figure 1 is a plan of my machine. Fig. 2 is an elevation of one side of the machine. Fig. 3 is an elevation of the other side of the machine. Fig. 4 is a foot-end elevation of the machine. Fig. 5 is a perspective view of one 'ofthe pockets of the blockcarrier. Fig. 6 is a side elevation, partly broken, .of the rip-saw gang and pointing knives. F ig. 7 is a front view of the same. Fig. 8 is a perspective view of a block of wood, broken,-.'and' showing the completion of a group or cluster of plugs made in one end, prior to the dismemberment of the group.

1 is the frame of the-machine.

2 is the block-carrier composed of an endless series of pockets 3 connected by hinged lugs 4, saidcarrier beingmounted upon terminal drums 5'and 6 as shown in Fig. 2.

7 is a vertical arbor upon which is mounted a hprizontally-disposed gang of rip-saws 8,',in any desired number,- said gang rotatingffin a plane above the blockcarrier and partially, overlapping said carrier, as seen in Fig. L to the extent to which the saws are intended to cut into the blocks from which the plugs are to be made. The several saws of the gang are spaced apart to cut the desired thickness of the plugs,

and said spacing is had and maintained, as shown "in Figs. 6 and 7, by intervening plates .9 which form heads for the point "cutting knives 10, which lie beside and between the saws in position to form the points of the plugs.

11 is a horizontal shaft, (Fig. 1) which carries the vertically disposed saw 12, Figs.

2 and 3, for cutting off the plugs from the block.

13 is a conveyer belt, Fig. 1, for receiving the plugs when out off by saw 12, and conveying them to the sack 14. at the footof the machine. I

15 is a hold-down device for the blocks. This may be of any suitable character. In the form shown it consists of a series of springy tongues cut in a wooden strip and properlymounted above the block-carrier 2 n positiontorest upon and hold down .the:

blocks vas the .poc'ketsof the carrier present them .to the .actionof the rip-saw gang 8 and.

pointing knives Q10.

Before pointing out further details, it will be well to describe the operation of the machine.

In Fig. 8is shown a block ofwood B, from one end of which has been ripped and pointed a group orcluster of plugsP which have not, asyet, been cutoff from the block. A block, such as B, before any cuts have been'made inlit, is placed, by the operator, in a recumbent position, in one of the pockets 3 of the carrier 2, as is shown in Fig. 2. In this pocket it is well held by the flanges of the pocket, its inner end being in position to follow a path to the rip-saw gang 8, as is shown in f ig. 4. The carrier 2 moves the block forward, and said block passing under the springs 15 is firmly held down in the pocket and is thus presented to the saws 8.

By these saws a series of horizontal kerfs are made in the end of the block, to the re uired depth, and, at the same time, two beve s are taken off the ends of the ripped slabs, by the pointing knives 10. As soon as the block passes the saw gang 8, and before it reaches the cut-off saw 12, the operator lifts it out of the pocket, turns it in his hand througha quarter turn, and so turned' replaces it in another pocket of the block-carrier, in advance of the hold-down 15 andsaw-gang 8. Once inore it is presented to the saw'gang8, which now makes in it a series of cuts atright angles to the' first series, and the pointing knives 10 cut off the remaining bevets,"

and thus the block is cut as in Fig. 8, with a group or cluster of, as yet, unsevered plugs I. Now as the block leaves'the'saw-gan '8,

the operator pushes'it forward in the poo et,

so that its 'cut end lies above the conveyer belt 13 and the bases of the plugs lie in line open-ended and are provided with side flanges which are reduced in height near the inner end so that the rip-saws may operate on the block end, the body of the block be ing well held by the flanges. The open top and ends of the pocket enable the operator to place a block'in it easily, and to remove it freely, and alsoto slip it forward through the inner end, to present its group of plugs to the cut-off saw. The several power transmitting connections will now readily be understood.

Power is led into the machine throughthe main counter-shaft 16 at the head of the frame, said shaft having the usual. fast and loose pulleys at 17, Fig. 1. A belt 18 from a pulley 19 on shaft 16 leads .to a pulley 20 on the vertical arbor 7, by which means the rip-saw gang- 8 is driven. A belt 21 from a pulley 22 on shaft 16 leads to a pulley 23 on the horizontal shaft 11, by which means the cut-ofl saw 12 is driven. Fig. 1. I A belt 24 from a pulley 25 on shaft 16 leads to a pulley 26 on an intermediate counter-shaft 27; and from a pulley 28 on said counter-shaft a belt 29 leads to a pulley 30 on a shaft 31 at the foot of the machine, which said shaft 31 carries the" foot drum 6 of the block-carrier 2; and thus said carrier is driven.

. In order to control the travel of the blockcarrier, to stop and start it at will, there is a gravity belt-tightener pulley 32 mounted on a pivoted frame 33, F 1g. 3, and adapted to rest normally upon and tighten the belt 24 which transmits power from the mainv counter-shaft 16 to the intermediate counters shaft 27. Mounted in frame 1 is a cross shaft 34, Fig. 1, having on one end a handle 35, Figs. 1 and 2, and a ratchet 36 controlled by a pawl'37. The shaft 34 carries a pulleycrank 38, Fig. 1, from which a line 39 extends down to the pivoted frame 33 of the belt tightener 32, Fig. 3. By operating the handle 35, the belt tightener may be raised or adjusted to fully control-the movement of the block-carrier.

The conveyer belt 13 is mounted on ter-" mmal .rolls 40 and is driven by a belt 41 leading from the intermediate counter-shaft veyer belt. v Having thus descrlbed my mventlon, what I claim as new and deslre to secure by Letters-Patent is,

prising a hinged series of separate horizontally disposed transversely extending pockets to receive, hold and advance the blocks, said pockets being open at the top and ends, each of said pockets having two together to provide a rigid structure and arranged topermit lateral adjustment of the blocks in the pockets, a gang of horizontally disposed saws arranged for rotation in the plane above the carrier and overlapplng the carrier to extend in the path of travel of the inner ends -of the blocks to cut in the block ends a group of plugs, and a verti erate in a-plane'immediately ad acent one side edge of the carrier and-the inner ends of the pockets. 7 I I '2.
