EXCELSIOR-IVIACHINE SPECIFICATIUN forming part of Letters Patent No. 307,646, dated November 4, 1884.

Application filed August 18, 1883.

To all whom iii-may concern.-

Be it known that I, PETER. HENRY, of St. Louis. Missouri, have made a new and useful Improvement in Excelsior-Machines, of which the following is a full, clear, and exact description, reference being had to the annexed drawings, making part of this specification, in whicht Figure 1 is afrontelevation of theimproved machine. Fig. 2, a side elevation; Fig. 3, a horizontal section, upon an enlarged scale, on line 3 3 of Fig. 2; Fig. l, a vertical section, upon an enlarged scale, on the line 4c 4 of Fig. 1; Figs. 5 and 6 details, being respectively a side and a top view of the mechanism employed in transmitting the motion of the main driving shaft to the feed-shaft; Fig. 7, a detail, being a view showing a portion of the scoring-knife; and Fig. 8 is a plan View of one half of the machine with the top bar or tie C partiallyremoved.

The same letters of reference denote the same parts.

The prevent invention has relation to the means employed in adjusting the cutter-head and to the means employed in feeding the block to the cutters and holding the remnant of the block that passes the feed-rolls. The general construction of the machine is also considered an improvement upon excelsiormachines as hitherto made.

Referring to the drawings, A, Figs. 1 and 2, represents the improved machine. The machine is double-acting, there being two sets of cutters, one of which is acting while the by means of the pulleys E E.

F Frepresent the connecting-rods leading from the cranks G G to the cutter-heads H H, respectively. The cutter-heads in their reciprocating movement are gnidedby bearings upon the uprights C G.

(No inodeLi To enable the excelsior to be cut in shreds of uniform width and thickness and of the full length of the block, the cutters must be adjusted accurately,and to provide for thisis, as stated, one of the prominent features of this improvement. The bearings, therefore, of the cutter-head are made adjustable in two directions-namely, toward and from the block from which the eXcelsior is cut and in a direction at right angles thereto. clearly in Fig. 8.

I and J represent bearings similarly attached to each of the uprights C C. The bearing I can be adjusted in the directions in dicated by the double-headed arrow i, and the bearing J can be adjusted in the directions indicated by the double-headed arrowj. lrVhen it is desired to set the cntterhead nearer to the block K from which the excelsior is produced, the bolt 2" is screwed into the upright O, causing the bearing I to be moved in the direction of the block K. The belt i holds the hearing I against the upright, in whatever position it may be moved into, by means of the bolt 2', and to provide for the movement of the bearing I and bolt the upright O is slottt d at c, substantially as shown. The cutter-head is adjusted in a transverse direction by means of the bolt XVhen it is desired to move the cutter-head, for instance, to the right, as seen in Fig. 8, the bolt j is screwed into the upright, causing the bearing J to be moved to the right, which in turn causes the cutter-head to be moved in that direction, as desired. The belt j serves to hold. the bearing J in place against the upright C, in whatever position it may be moved into, by means of the bolt j, and to provide for the movement of the bearing J and the bolt 3' the up- I This is shown' journal ed in the bearings n a, and are provided with the gears a M, which in'turn engage with the worms 0 0 upon the shaftO. Thislast-named shaft turns in the bearings 0 0, and is pro vided with the gear 0 which engages with the gear 19 on the shaft P. The shaft P turns in the bearings 19 12 and at its upper end is provided with a ratchet, 19, Figs. 5 and 6. The driving-shaft B is provided with a grooved cam, Q, Figs. 5 and 6. The driving-shaft, through the cam Q, operates at proper intervals a "dog,p which in turn acts upon the ratchet p upon the shaft P.' The motion of the driving-shaft is thus communicated to the feed-rolls N N, and the various parts are so constructed and operated as to cause the block K to be fed toward the cutters just before the cutters are about to operate.

To enable the remnant 7c of the block K to be suitably held in the machine after it has passed the feed-rolls, the following means are employed.

S represents what I term the pressure-bar, which is capable of being drawn down in its bearings, so as to bind the block K after the latter shall have passed the feed-rolls,as shown in Fig. 4. The pressure-bar S, at its end, by means ofthe rod s,is connected with the weight s,and as soon as the block K has passed the feed-rolls the weight operates, through the rod 8, to draw the bar S downward, and there by to press upon and confine the blockK,

whose lower end at that time rests upon a sta- In this manner the tionary bar, S, Fig. 4. remnant of the block K is retainedin position in the machine and prevented from causing any damage to the machinery until the attendant can withdraw it. To raise the pressure bar again, the lever T, Figs. 1- and 2, is employed. The rod 8 is, asshow-n in Fig. 2, connected with the lever T, the lever T being slotted at t to receive a pin. t, which passes slidesSfS".

through the rods and intothe slot 15. By lifting the free end of the lever T the pressurebar S is raised, as desired. The bar S and the upper feed-roll are permanent lyconnected and move upward and downward together. To this end the bar S, at its ends, is attached to the These slides contain the feed-rollshaft bearingsand they can be moved vertical- 1y upon thenprights O O. The slides are also supplied with the-projections S S, which come respectively above and beneath the upper worm, 0. This upper worm, 0, can be slipped upward and downward upon the shaft O, and

when the bar S and upper feed-roll are moved upward and downward, as described,the worm tage accruesz As the cutter head and knives are movedupward at one side of the machine, the cutter-head on the opposite side of the machine and the mechanism immediately therewith "connected are moved downward. The weight of the descending mechanism therefore operates to counterbalance the weight of the ascending mechanism, and the result is, the operation of cutting the wood is greatly facilitated.

The mechanism used in transmitting the motion of the main driving-wheel to the feedshaft is understood by referring to Figs. 5 and 6.

Upon the upper end of the shaft P a box, 1), is journaled. The box has a projection, 19, which engages in the groove of the cam Q. The rotary movement of the cam Q therefore causes the box 19 to oscillate upon the shaft P,'as indicated by the dotted lines in Fig. 6. The ratchet p which is fastened to the shaft P, is contained within the box-p. The pawl 19 is pivoted to the box 19. As the box 19* oscillates in one direction the pawl is moved with it and the point of the pawl rides upon the teeth ofthe ratchet. As the box is moved in the other direction the pawl engages in the ratchet, causing it and the shaft P to rotate, t

and, through the mechanism heretofore described, to operate the feed-rolls. A cover,

19", serves to'inclose the pawl within the box feed-rolls, N N, a pressure-bar held down by ICO a weight, a supporting-bar, S, slides S, projections from said slides, wornrscrews 0 0 on shaft 0, gears 0 p, shaft P, a ratchet and pawl at the upper end of the latter, arm 12, and a can, Q, on the main driving-shaft, substantially as described.

In an excelsior-machine, the combina tion, with the shaft B, of the grooved cam thereon, the shaft P, arranged with its axis at right angles to the direction of the axis of the driving-shaft and geared to the feed-rollers, which are at right angles to it and turning in bearings 19 the ratchet p, the dog f, and the devices described for transmitting intermittent rotation to the feed-rolls, which adjusts the staff to the cutters, all constructed and adapted to operate substantially as described.

3. In an excelsior-machine, the combination, with the uprights O and cutter-head,

faced as described, ot' the adjustable bearings I passing through slots in the frame, all con structed and adapted to operate substantially in the manner and for the purposes specified.
