GAINING-MACHINE.

Specification of Letters Patent.

Patented Feb. 25, 1908.

Application filed August 24. 1907- fierial No. 389.936.

To all whom it may concern:

Be it known that I, JOHN R. THOMAS, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Gaining-Machines, of which the following is a specification.

It-is the object of my invention to provide a new and useful gaining machine such as is employed for instance in providing a timber with gains or grooves cross-wise of the timber, and the invention consists in new and useful instrumentalities for initiating, re.

versing and stopping the stroke of the gaining-head, and in various other instrumentalities which will be more readily understood from the following description and claims, and from the drawings, in whichlatter:

Figure 1 represents a side elevation of my improved device. Fi 2 is a plan view of the same, with the table partly broken away. Fig. 3 is a front elevation of the same. Fig. 4 Fig. 5 is an enlarged detail in side elevation of the tripping mechanism. Fig. 6 is an end elevation of the same. Fig. 7 is a plan view of the same, shown in connection with the tappets. Fig. 8 is a plan view of the guide for the trip. Fig. 9 is a vertical section of the same on the line ac -a: of Fig. 8; and, Fig. 10 is a sectional detail on the line y of Fig. 1 showing the manner of mounting the driving bevel-friction wheels.

1 represents a column which supports a saddle 2 for the gaininghead reciprocating in slide-ways 3 on the column. 4 is a slide slidable in guide-ways 5 at the front of the saddle and carrying the bearings 6 for a gaining-head shaft 7, to which a suitable gaining-head 8 is adapted to be secured. The gaining-head is adapted to be rotated by a belt passing from above under a pulley 9 on the saddle, thence around a pulley 10 011 the shaft 7, thence backwardly, under a pulley 11 on the saddle and upwardly from the latter, the belt being operated by suitable driving pulleys from above, suitable take-up mechanism being provided to take up the slack of the belt which maybe occasioned by the change of positions of the shaft 7. Suitable limiting plugs ].5 are adjustable in slots 16 of the slide and are adapted to strike a rail 17 of the saddle for limiting the up and down movement of the slide, these plugs being releasable in. usual manner.

There is a rack 21 at the bottom of the saddle with which a gear 22 engages, the gear being on a shaft 23 journaled in bearings 24 of the frame. A pinion 25 meshes with the gear 22 and is on a shaft 26 journaled in bearings 27 of the frame, this shaft also having a worm-wheel 28 thereon which is meshed by a worm 29 on a shaft 30 journaled in bearings 31 in the frame. The shaft 30 also carries a beveled-friction wheel 32 with which beveled-friction wheels 33 34 are adapted to selectively engage for turning the shaft 30 in reverse directions, the bevelfriction wheels 33 34 being on a sleeve 35 having spline-connection 36 with a driveshaft 37 journaled in bearing 38 of the frame and provided. with suitable driving connection as for instance pulleys 39. .The bevelfriction wheels 3334 are spaced apart sufliciently to'permit the same tobe positioned out of contact with the bevel-friction wheel 32 and to permit either bevel-friction wheel 33 or 34 to be brought into contact with the bevel friction wheel 32 by the end wise shifting of the sleeve 35. This end wise shifting is accomplished by means of a block 41 taking about the sleeve and having a slot 42, with the walls of which the end of a shifter-finger 44 is adapted to engage, the shifter-finger being on a rock-shaft 45 having a manipulating arm 46 secured thereto, the arms 44 46 and the rock-shaft 45 thus preferably forming a bell-crank lever for the manipulation of'thc bevel-friction engagement.

There is a moving agency provided for normally causing one of the sliding bevelfriction wheels to engage the driven bevelfriction wheel as well as means for normally Thus a rod 51 depends from the arm 46 through a lug 52 on the frame and at its bottom carries a collar 53 positioned by means of a set-nut 54 and a j am-nut 55. A spring 56 takes about the rod between the lug and collar for normally pressing the shifter-arm 46 down- An operating lever 61 is articulated with the. rod 59 at 62 and is pivoted on a bolt 63 to the frame and at its outer end has ahandle 64 for manual manipulation, the object of the operating lever being to raise the outer end of the shifter-arm 46 for bringing the frictionwheel 34 into engagement with the frictionwheel 32.

To the rod 59 a bar '66 is pivoted at 67. A link 68 is articulated with, the bar 66 at 69 and with a shifting-lever 70 at 71, the shifting-lever 70 being shown as a bell-crank lever pivoted to the operating lever at 72 ad j acent to the handle 64. The link is preferably provided with a turn-buckle 73. The bar 66 is adapted to slide in a slot 76 of a bearing 77. The bar 66 is provided with a shoulder 78 adapted to engage the bearing when the bar is raised for retaining the bar in raised position. The shoulder 78 preferably engages a hardened bearing-plate 80 at the top of'the hearing, which thereby forms a mating shoulder for the shoulder 78, and forms a rest for the bar 66. T here is a spring 81 in a pocket 82 of the bearing 77 for normally urging the shoulder 78 toward the stop or rest 80. This spring 81 acts upon the bar 66 for normally causing engagement between the shoulders 78 80 when the outer end of the operating lever 61 is depressed for raising the rod 59 and thereby raising the outer end of the shifter-arm 46 for causing engagement between the friction-wheel 34 and the friction-wheel 32. I preferably provide an adjustment for the bearing 77, by providing the same with slots 83 through which bolts 84 are received into the column, and by providing the column with lugs 85 into which bolts 86 are threaded for engaging the bearing.

The saddle is provided with a pair of tappets 87 88 the tappet 87 being adapted to shift the bar 66 laterally in the forward movement :of the saddle for disengaging the shoulders 78 80, and the tappet 88- being provided with a shelf 89 upon which an anti-friction roll 90 at the upper end of the bar 66 is adapted to ride, the upper face of the shelf being provided with a downward slope 91 at its rear end for readily taking under the antifriction roll 90 in the rearward movement of the saddle for raising the bar .66, and thereby partially raising the outer end of the shifterarm 46 for positioning the friction-Wheels 33 34 in neutral position with relation to the friction-wheel 32 for causing the saddle to be at rest. The tappet 87 is provided with a striking lug 92, preferably recedin downwardly and rearwardly, this lug stri ring the roller for moving the bar. The tappets 87 88 are adjustably positioned lengthwise of the saddle along a guide-way93, as by means of T-bolts 94 whose heads are received in an undercut slot of the guide-way and have nuts 95 at their outer ends, for determining the length of stroke of the saddle.

It will be understood that the normal position of the frictions is a neutral position,with the friction-wheels 33 34 positioned intermediately of their limits of movement and out of contact with the friction-wheel 32. This position is attained when the roller 90, or

' other contact part which may be used therefor, rests on the shelf 89. If it is desired .to initiate movement of the saddle, the handle 64 is pressed downwardly, thus raising the rod 59 and causing the shoulder 78 to be received upon the rest 80, thus causing engagement between the friction-wheels 34 and 32 and causing forward movement of the saddle. When this forward movement has progressed sufficiently for causing the lug 92 to strike the roller 90, the shoulder 78 will be forced off of the rest 80 and the bar caused to drop,

the tension of the spring 56 thereby forcing engagement between the friction-wheels 33 movement of the saddle until the shelf 89 passes under the roll or contact part 90 for raising the bar 66 and the rod 59 and causing the friction-wheels 33 34 to be shifted into neutral position withrelation'to the frictionwheel 32 and thereby causing cessation of movement of the. saddle.

Up and down movement of the gaininghead may be had by manipulation of the levers 1.01 which are pivoted at 102 on upand 32 and causing the reverse or rearward rights 103 secured to the saddle and' are connected at their front by a cross-bar 104 serving as a handle and at their rear by a crossbar 1.05 on which suitable weights 106may be secured for normally holding the slide in upward position. At each side of the slide a I rod 107 is pivoted at 108 to which the levers 101 may be clamped at desirable points by swivel clamps 109. I

The timber, which is shown at 111 is adapted to be clamped upon a table 112 to which lengthwise movement may be imparted in suitable manner for positioning the .timber or other work being operated 0mm suitable points with relation to the cuttinghead of the machine. The table is provided with tracks 113 supported on wheels114. The table also has a rack 115 with which a gear 116 meshes, the gear being driven from a pinion 117 on a shaft 118 which also carries a gear 119 meshed by a pinion 120 on a shaft 121 carrying a hand-wheel 122. 123 124 are tappets adjustable lengthwise of a rod 125 on the table. 126 is a stop-block normally out of range of the tappets. It slides in a bearing 127 and has connection with a footlever 128 by means of which it is adapted to lated with said rod and with said operating latter, said driving means comprising a shiftbe raised into range of the tappets for forming a definite stop for the lengthwise travel of the carriage for positioning the timber lengthwise with relation to the cutter head on the saddle 2.
