. PATENT FFICE.,
,VVIL'LI'AlVI II.. `ALKIIR, OF FOND DU LAC, yWISCONSIN.
IMPROVEMENT IN sHlNGLE-sAwlNG MACHINES.
Specification forming part of Letters Patent No. 4 I,55., dated February 9, 1801.
To @ZZ whom, t may concern,.-
Beit known that I,V WILLIAM H. WALKER, of Fond du Lac, in the` county of Fond du Lac andtat'e of Visconsin, have invented a new and Improved Shingle Machine; and, I do hereby declare that the 'following is a full, clear, andexact description of the same, reference being had to theaccolnpanyiug drawings, mak-V ing apart of this specification, iuwhiych- Illigurefl isa side Asectional'view of my invention, `talieznin the line a: x, Fig. 2;v Fig. 2, a
horizontal section, of the same taken in the line y. y, Fig. l;,Fig. 3, an end View of the same withzthe-upper. part in section, as indicated by the 'line zjz, Fig. Al.
- Similar .letters of `reference indicate corresponding parts in the several figures. This invention relates lto a new and improved shinglemachine of that class in which sa\vs1 are.,en lployed for cutting the shingles from the .bolt. t
l AThe invention consists in an arrangement whereby a circular in horizontal position ismoved toaud fro Vbetween two stationary bolt-holders, thereby obviating the necessity of moving the bolts and securing constant action of the sawin one bolt or the other, and reducing the .machine tothe smallest possible ,compass for plurality of'bolts; and in an arrangement Whereby the shelf or apron upon y which t-he bolt drops vto `be adjusted for the sawis `driven ,from under the bolt to allow the .shingle vtodrop when sawed; and in a novel way of lifting the bolt not being acted upon from the saw, and in an arrangement whereby the feeding device may be worked automatically or Vby hand, as may be desired, for soft or hard timber.
To enable those `skilled in the art to fully understand and construct my invention, I will proceed to describe it. f j Arepresents a'rectangular framing, which may ybevconstructed in any proper way to sup- `port the working parts ofthe machine. B repframing and allowed to slide thereon to a cer` tain extent, said bar being moved or operated by a lever, E, attached to the framing. The bar D has two concave recesses, e e, made in it, which, when the bar D is moved or adjusted so as to bring said recesses in line with the shafts c c', will let the latter down a trifle. These recesses are shown clearly in Fig. l, and it will be seen that when the bar D is moved or adjusted-so as to throw the recesses e c out of line with the shafts c c the latter will be raised a trifle, the length of the movement of said shafts being equal to the depth of the recesses e e.
F iepresentsa sliding frame, which is placed within the framing A and arranged to work horizontally onl suitable guides or ways f. (Shown in Fig. 3.) This frameF has a lever', G, connected to it by a rod, H, and to the bottom of the sliding frame F there is secured transversely a horizontal plate, I, the sides of which are of concave forni, as shown at g g in Fig. 2. Y
On each wheel C C there are secured at opposite points two friction-rollers, h 7L', and these rollers, in connect-ion with the concave sides g g of the plate I, communicate a reciprocating movement to the frame F,the rollers h of the wheel C acting against the concave side g and moving the frame F in the direction of arrow l, and the rollers h. of the wheel C acting against the concave side g'and moving said frame in the direction indicated by arrow 2. The rollers of each wheel C G' act the pinion b on the shaft of the drivingpulley B.
J represents a circular saw which is on the upper end of a vertical shaft, K, in the sliding frame F. This shaft K has a pulley, L,
upon it around which a belt passes for driving or rotating the saw.
In the upper part of the frame F there are strip m.
,placed two tilting frames, M M. These frames are each formed of a bar, l, pivoted at their centers to opposite sides of the upper bearing, j, of the shaft K, and at the ends of the bars fl there are attached parallel arms k k, which extend outward at right angles from the bars i i, and are at the sides of the upper part of the frame F. The arms la lc and bar t' of each frame M may be formed all of one bar, or the arms k may be made separately and attached to t'. Y
To the outer parts of the arms .7c k of each tilting frame M there is attached a horizontal plate, N, the sides ot' which extend down underneath the arms 7c and lit in grooves ZZ', made in horizontal hars O, attached to the framing A. Each bar O has two grooves, ZZ', 'made in it, oneahove the other, as shown in Fig. l, the division strip m of said grooves being pointed at its front end, and the two grooves of each bar() terminatingin one wide groove, a, at the front end of the division# (See Fig. l.)
Between the front ends of the bars Oat cach end of the framing A there is placed a horizontal shaft, P. These' shafts have each a ratchet, Q, placed on them at their centers, and tothe back part of each horizontal plate N.at the under side, there is attached a pawl, 0. At each end of the shafts l? there are placed triangular cams Qthose on each shaft being so arranged that when a pivot or angle of one cani at one end of a shaft is uppermost the cam at the opposite side will have a point down and a flat sideupperrnost. These earns Q Q' serve to tilt the frames M and incline the plates N, which is done atv the termination of eat-h movement of the frame F, in conse c uenceof the )awls Ocominoiin contact with l l :a
theratchets Q, and turning the shafts P one.- siXth of arevolution, the point of the cam which is turned upward striking the plate N above it and throwing its side upward in the wide groove n, in line with the upper narrow groove, Z, in which groove the elevated side of the plate N enters, while its opposite and lower side enters the lower gi'oovc,l,of its bar O. By this arrangement, therefore, the plates N are alternately tilted or inclined, rst in one' direction and then in the other. L
On the framing A, at each end, there is placed a rectangular frame, R, and in these frames R the bolts from which the shingles are cut are secured by dogs S S', one at each side. The dogs S are permanently attached to the frames lt; but the dogs Sare sliding ones, and are operated or forced outward by an arm, T, attached to the frame F, and brought back by a weight, U. This drawing out of the dogs lS releases the bolts and allows them to fall upon the plates N, when they are inclined by the tilting of said plates j ust before they are presented to the saw J by the movement of the frame F, .v
the bolts being dogged just after they are inclined by the action of the weights U or other equivalent device.
The bolts are raised from the saw at the termination of each movement of theframe F by means of a double sliding wedge, A', whichis placed on the upper part ofthe framing A, between the two frames R R, as shown clearly in Fig. l. This Wedge A is moved by the upper end ofthe saw-shaft K,which comes in contact with aprojection, ax, at each end ofthe wedge, and shoves the latter underneath the flames R at their inner ends, thereby relieving the saw, during its backward movement, from contact with the bolts.
The frame F may, when the shafts c c are dropped or lowered so as to free the rollers h h from the plate I, be worked or operated by hand through the medium of the lever G.
, Having' thus described my invention, what I'claim as new, and desire to secure by Letters Patent, isf
l. The arrangement of a circular saw in horizontal position between two stationary bolt-holders or rectangular frames, R R, between which it is driven to and fro in the sliding frame F to cut a shingle at each reverse movement, in the manner herein explained.
2. The wheels C G', provided with frictionrollers h. h, in combination with the plate l, and operating in the concaves G G, when arranged substantially as and for the purpos set forth.
3. The movable bar D, provided with recesses e e, and arranged, as shown,in relation with the shafts c c', for the purpose of raising and lowering the same, to render the frame F automatically operative or inoperative,as may be desired.
4. The tilting frames M, arranged, as shown, on the frame F, and provided with the plates N ,having pawls Oattached, in connection with the bars O, provided with the grooves ZZ', and the shafts P, provided with the triangular cams Q and ratchets Q, all arranged to operate as shown, for the purpose of inclining the bolt-s so that the shingles may be sawed in taper form and drop from their place.
5. The arms T, attached to the sliding l'rame F, in combination with the weight U, or its equivalent, for the purpose of operating the sliding dogs S', when used in connection with a circular saw mounted in a reciprocating carriage, as set forth.
6. The double wedge A', placed on the upper part of the framing A and arranged to operate by the movement of the saw-frame F, substantially as and for the purpose specified.
WILLIAM H. WALKER.
