LOUIS KOSS, OF INDIANAPOLIS, INDIANA.
VENEER-SLICER.
SPECIFICATION forming part of Letters Patent No. 793,306, dated June 27, 1905.
Application filed April 4, 1904: Serial No. 201,414.
To all who), if many (antral-n:
Be it known that I, LoUIs Koss, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvcments in Veneer-Slicers, of which the following is a specilication.
In the large and heavy veneer-slicers dilliculty has hereto fore been experienced, because of the extreme necessary weight of the knife and its support, in retracting the knife each stroke of the flitch-table prior to the return of the ditch in order that the knife may not drag upon the llitch.
The object of my invention is to provide means for supporting the knife in such mannor that it may be automatically shifted for the purposedescribed with the exertion of but little force.
The accompanying drawings illustrate my invention.
Figure 1 is a rear elevation of a machine embodying my invention; Fig. 2, a side elevation; Fig. 3, a section on line 3 3 of Fig. 1; Fig. 4:, a detail on a somewhat larger scale on line 1 1 of Fig. 3. Fig. 5 is a section on line 1 1 of Fig. 3 on a very much smaller scale in order to show the entire width of the machine, and Fig. 6 is a detail of the limiting adjustments for the pivoted knife-bar.
In the drawings, 10 indicates the main frame of the machine, provided at one end with suitable standards 11, which form guides upon which is mounted the sliding flitch-table 12, said table being reciprocated by means of pitmen 13 13, connected to suitable gears 11.
Mounted upon suitable horizontal ways 15 on the main frame 10 is a cross-bed 16, which is provided with the usual feeding-nuts threaded upon the feed-screws 17, said feed-screws being connected by a suitable cross-shaft and gears 18.
Secured to a shaft 19 is a gear 19, and said shaft carries a gear 19", which drives shaft 18. Gear 19 meshes with a gear 20, which gear is carried by a shaft 21, provided with a feeding-ratchet 22, said ratchet being operated by means of the usual feed-lever 23, pawl 24, and pitman 25, adj ustably connected to the arm 26, carried by the shaft of one of the gears 11,
the arrangement being such that as the gears 14: rotate the feed-screws 17 will be automatically operated a desired amount so as to feed the cross-bed 16 forward toward the flitchtable 12.
The cross-bed 16 is provided at its forward upper edge at each end (and at intermediate points, if desired) with pin-sockets 27, which lie parallel with the plane of movement of the Hitch-table 12 and are adapted to receivebearing-pins 28, which in turn are received upon their uppersides bysimilar notches 29, formed in the lower forward edge of the knife-bar 30. The knife-bar is very heavy and extends rearwardly, as clearly shown in Figs. 2 and 3. For the purpose of supporting the rear edge of the knife-bar 30 I provide the construction shown in Figs 3, a, and 5. At one side of the cross-bed 16 and parallel with the direction of movement of said bed and at right angles to pins 28 is a pin 31. Pivoted upon pin 31 is a bell-crank lever 32, the upper arm of which normally stands vertical. The upper arm of lever 32 is bifurcated, and in the crotch of the bifurcation 1 form a socket 34, adapted to receive the lower ball end 35 of an adjustable strut 36, the upper ball end 37 of which fits in a suitable socket 38, formed in the under surface of the rear edge of the knife'bar 30. The other armof the bell-crank 32 is connected by a pitman 89 with an arm *0, which arm is splined upon a rock-shaft 4:1 and is capable of being moved alongsaid rock-shaft by means of a fork L2, secured to the cross-bed .16 and moving therewith. At the side of the cross-bed 16 opposite bell-crank lever 32 I provide another pin 31, upon which is pivoted an upright bifurcated arm 43, which is in all respects similar to the upright arm of the bell-crank 32 and is provided with a suitable socket in which is arranged the adjustable strut 36, which engages at its upper end with the knife-bar 30. The upper arm of lever 32 and the arm 43 are connected by a cross-arm 33, so as to be moved simultaneously by a movement of the rock-shaft all. In order to prevent too great retractile movement of the cutter-bar 30, I provide suitable zuljusting-stops d4. Secured in bar 30 near each end is a bolt 51, which passes down through a slot 52, Fig. 6, in bed 16 and has an adjustable nut 53, which when the bar is swung forward by straightening the toggles is brought solidly against the bed 16.
For the purpose of operating rock-shaft 41 at proper intervals I secure thereto an arm 45, (see dotted lines in Fig. 1,) to which is connected a rod 46, which extends upward parallel with the line of movement of the flitch-table 12. This rod extends through a pair of perforated cars 47 and 48, carried by the flitch-table, and near each end the rod is threaded to receive adjustable collars 4C9 and 50.
In operation, with the parts in the position shown in Figs. 1, 2, and 3, the knife 30 has been adjusted to the flitch in position to take the desired slice therefrom as the flitch is being moved downward. In this position the knife-bar 30 has been rocked forward by a straightening of the toggles formed by the bell-crank 32 and its strut 36 and arm 43 and its strut 36. This movement brings nuts 53 solidly against bed 16, so as to prevent any drawing in of the knife into the flitch. As soon as the flitch passes downward beyond the knife the ear 4'7 engages collar 49, and thus rocks shaft 41, so as to draw arm 40 downward, thus resulting in a swinging of arm 43 and the vertical arm of lever 32 and permit ting the knife-bar 30 to swing backward upon the pins 28, thus retracting the knife 30 from the face of the flitch. The i'litch thereupon passes upward, and during this upward movement the feeding mechanism rotates the feedscrews 17, so as to advance the cross-bed 16 the desired amount for the next slice. After the flitch has passed the knife in its upward movement the car 48 engages collar 50 and shifts rod 46 in the opposite direction, so as to return rock-shaft 4:1 to its normal position, and consequently straightens I the toggles which support the knife-bar to return the knife to its normal position and in position to take the next slice from the flitch.
The knife-bar 30 may, if desired, be nearly balanced upon the pins 28, only enough overbalance being permitted to insure the steadiness of the knife-bar upon the struts 36. As
a consequence only a very little force is required to shift the knife out of and into the plane of flitch.
I claim as my invention 1. In a veneer-slicer, a knife-bar-supporting bed, a knife-bar pivotally supported there on upon an axis substantially parallel with the cutting plane and to one side of the center of gravity of said bar, means for automatically swinging said knife-bar upon its pivotal support, and independent means for holding the knife-bar against the action of the flitch.
2. In a veneer-slicer, the combination, with a Hitch-table and means for reciprocating the same, of a knifebarsupporting bed, means for advancing and retracting said supportingbed toward and from the flitch-table, a knifebar pivotally supported upon said bed upon an axis substantially parallel with the cutting plane and to one side of the center of gravity of the bar, means for limiting the gravity movement of said bar about its axis, means for automatically swinging said knife-bar upon its pivotal support, and means for holding the knife-bar against the action of the 8. In a veneer-slicer, the combination of, a knife-bar bed, a knife-bar pivotally supported thereon upon an axis substantially parallel with the cutting plane, a pair of toggles forming a support between the knife-bar bed and the knife-bar to the rear of the pivotal axis, and means for operating said toggles to swing the knife-bar upon its axis.
4:. In a veneer-machine, the combination, with a suitable frame, and a flitch-table reciprocably mounted thereon, of a knife-bar bed mounted on said frame, means for feeding said bed toward and from the Hitch-table, a knife-bar pivotally mounted upon said bed upon an axis substantially parallel with the cutting plane, a pair of toggles forming a support between said bed and the knife-bar to the rear of its axis, a connection between said toggles to produce simultaneous movement, a rock-shaft, means carried by the rock-shaft for operating the toggles at any point of adjustment of the knife-bar bed, and means operated by the flitch-table for operating said rock-shaft.
In witness whereof I have hereunto set my hand and seal, at Indianapolis, Indiana, this 31st day of March, A. D. 1904.
