EXCELSIOR-MAKING MACHINE.

Specification of Letters Patent.

Patented Oct. 9, 1906.

Application filed February 11, 1905. Serial No. 245,182-

. and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in excelsior-making machinery wherein rotatable cutter-heads provided with suitable knives are supported at a distance one from the other with conveying mechanism interposed between said cutter-heads in such manner that the material out by the knives upon one of said cutter-headsshall be deposited in approximate laminations upon a conveyer, with the grain of the wood extending transversely of said conveyer, and subsequently fed by said conveyer to a second rotatable cutter-head having suitable cutting-knives thereon, which knives cut longitudinally of said grain, as hereinafter more fully described.

The object of the invention is to provide a machine of the class described so constructed as to facilitate the operation of cutting excelsior, thereby allowing a great quantity of timber to be fed to a machine in a given time; and the invention contemplates the production of a simple, durable, and economical machine for the required purpose which is so arranged that the several parts thereof are easily accessible for the purpose of repairs or renewal, all as hereinafter more fully described, and specifically pointed out in the claims.

In the drawings, in which similar characters of reference indicate corresponding parts in all the views, Figure 1 is a side elevational view of a machine constructed after my invention. Fig. 2 is an end elevational view looking toward the right of Fig. 1. Fig. 3 is a fragmentary longitudinal sectional view taken approximately centrally of the machine. Fig. 4 is a fragmentary detail hereinafter referred to. Fig. 5 is an enlarged detail fragmentary view showing the manner in which shavings are placed in laminations between the conveyer-belts hereinafter referred to.

Referring to the parts, 1 is a base, to which are connected the uprights 2, which uprights are connected by means of the cross-pieces 3 and 4. Extending laterally of the machine are other cross-pieces 5 and 6, which serve as portions of the supporting-frame of the machine. Mounted in suitable bearings 7 8 is a shaft 9, which shaft is driven by the pulley 10 from any suitable source of power. Carried on the shaft9 is a cutter-head 11, which cutter-head carries the planing-blades 12, which planing-blades are adapted to cut the shavings from the log 13, which may be fed thereto in any suitable manner and by any preferred form'of feeding mechanism, which mechanism, however, forms no part of the present invention and is well known in the art, and hence is not illustrated herewith; but it will be observed that the log 13 is so held with relation to said cutter-head 11 that the end of said log points toward the right-hand upright 2 in Fig. 1 that is, so that the grain of the wood extends transversely to the longitudinal axis of the shaft 9, on which said cutter-head 11 is carriedand the cuttingblades 12 rotate in contact with the log 13,

so as to cut shavings from said log longitudinally of the grain of the wood. At the opposite end of the frame, which is indicated generally by the reference-letter A,-is a cutterhead 14, in which is secured a suitable number of slitting-knives 15*, this cutter-head 14 being rotatable with the shaft 9 which shaft extends substantially parallel with said shaft 9, and the slitting-knives 15 are so positioned with relation to the conveying-belts, which travel parallel with said shaft, that said slitting-knives cut the shavings fed thereto longitudinally of the grain of said shavings.

Interposed between the cutter- heads 11 and 14 are conveying- belts 15, 16, and 17, which are arranged as follows: The belts 15 are carried around the pulleys 19, 20, 21, and 22, any one of which may serve as a drivingpulley, though it is preferred that the pulleys 21 shall be adj ustably secured in the brackets 23, so as to permit moving said pulleys vertically for the purpose of tensioning said belts 15.

It will be observed in Figs. 1 and 4 that the belts 15 are arranged in parallel series upon the pulleys 19, 20, 21, and 22 and that a bearing-pulley 24 is provided opposing said pulley and bearing upon the belts 15.

The pulley 21 on shaft is an idler and moves freely up and down in the operation of the machine, so that the shavings may be deposlted on the belt 15 in laminations of vary mg thlckness, thus pressing said belt 15 downwardly from the belts 16 and 17.

Cooperating with the belts 15, which serve as the feed to the cutter-head 14, is said belt 17, which is carried in close proximity to the rotatable cutter-head 11 at the upper port1on of said belt, said head 11 carrying the planer-knives, and said belt 17 is driven in the directlon indicated by the arrow in Fig. 1, so that as the shavings are cut from the log by the knives 12 said shavings will be carr ed between the belts 17 and 15 and in the directlon indicated by the arrows in Fig. 3 between the belts 15 and 16.

The portion of the belt 17 next the cutterhead 11. extends obliquely away from said cutter-head from top to bottom, so as to leave but a slight space between the upper portion of the belt and said cutter-head near the upper portion thereof and a wider space of two or three inches near its bottom por t1on, so as to provide a space in which the shav ngs from said cutter-head may accumulate 1n laminations which are carried down by the belt 17 and deposited on the upper surface of the belt 15 in'laminations, with the gram of the 'wood extending transversely of said conveyer-belt 15. i

The belt 17 may be driven in any desired manner either by separate connection or fric tionally from the belt 15, and likewise the belt 16, which when moving toward the cutterhead 14 is carried close to the belt 15, may be driven either frictionally from the belt 15 and the shavings deposited thereupon or from a separate source of power.

In the operation of the machine the planerk nves 12 cut from the log 13 shavings of considerable width, which shavings during the progress of the work of the machine are deposited in laminations upon the upper port1on of the belts, 15, as described and as shown in the detail view Fig. 6, and it will beevldent that the belt 16 will be driven by the frictional contact of said shavings therewith. The belt 16 passes around the pulleys 28, 29, and 30 and between 20 and 31, as shown in Fig. 3. Near the discharge end of the conveyer formed by the belts 15 and 16 plates 32 and 33 are provided ,which plates are supported by the brackets 34 and 35, respectively. Said plates 32 and 33 terminate in angular outer edge portions, which are in close proximity to the slitting-knives 15, carried by the cutter-head 14, so that as said cutter-head 14 is rotated the laminations of shavings will be cut by the knives 15 into the excelsior, the said cutter-head 14 being driven by the shaft 9 and driving-pulley 10 The operation of the machine is as follows: The log 13 being fed to the machine for operation of the knives 12 thereupon broad shavings will be cut from said log and be carried by the belt 17, as described, to the con carried in the direction indicated by the ary rows into contact with the disk 14, where upon the knives 15*, which are preferably more numerous in the head 14 than the knives 12 in the head 11, will cut the shavings into the required strips required to make a good quality of excelsior'with the grain extending longitudinally of the shavings.

It will be observed that the cutter-head 11 is situated in a higher plane than the cutterhead 14 and that a part of the belt 17 is in approximately vertical position, whereby the feed from one cutter-head to the other is materially assisted, and it will be further observed that the shafts 9 and 9 supporting said cutter-heads, are in substantial parallel- Having described my invention, What I claim, and desire to secure by Letters Patent, 1s
