SPECIFICATION forming part of Letters Patent No. 766,295, dated August 2, 1904.
Application filed August 12, 1902. Serial No. 119,457. (No model.)
To (H w/wm, it 'nmq concern:
Be it known that l, V ILLIAM TIIORP, millwright, a citizen of the Dominion of Canada, and a resident of the town of Rat Portage, in the district of Rainy River and Province of Ontario, ()anada, have invented a new and useful Shingle-Cutting Machine, of which the following is a specification.
This invention relates to machines for sawing shingles; and it has for its objects, among others, to provide an improved machine of that type employing a double-edged band-saw by which a greater number of shingles can be cut at a given time, to provide against lost motion, to save manual labor, to produce more shingles from a given amount of material, to cut smooth shingles without curved scores thereon, and to avoid all waste in the form of.
sawdust by sawing with the grain of the wood, thereby producing a valuable fibrous shaving.
Other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be particularly pointed out in the appended claims.
The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which Figure l is a front view of my improved shingle-machine. Fig. 2 is a top plan of one half of the machine. Fig. 3 is a similar View of the other half, the line 1 2 in each of these figures being identical. Fig. 4: is an elevation of the machine from the side from which it is driven. Fig. 5 is a top view of the ratchet set-works placed at each corner of each carriage, by means of which the block to be sawed is fed to the saw. Fig. 6 is a front view of the ratchet set-works, showing also a section of the carriage-slide. Fig. 7 is a transverse section on the line 3 4 of Fig. 5. Fig. 8 is a section on the line 5 6 of Fig. 6. Fig. 9 is a view showing the bracket by which the reciprocating bar is attached to the carriage, a portion also of the reciprocating bar being shown detached. Fig. 10 is a perspective view showing the bar and bracket locked. Fig. 11 is a side elevation of the bracket with the bar in position. Fig. 12 is a section through 5 the upper part of one of the upright arms of the casting in which the reciprocating bar slides.
Like letters of reference indicate like parts throughout the several views.
Referring now to the details of the drawings by letter, the main framework of the machine, as herein shown, is composed of two castings A A, firmly connected together by the rods B, in this instance six being employed and being preferably of steel-shafting, the whole being set on the feet 0 C.
Dis the main driving-pulley, adapted to receive its power from any suitable source, and
this drive-pulley is fast upon the shaft E,
mounted in suitable bearings on the framework, and to one end of which shaft is attached a pulley F, around which and around the pulley F on a corresponding shaft F passes the band-saw F which is provided with teeth upon its opposite edges, as seen clearly in Figs. 2, 3, and a. To the other end of the shaft E is affixed a conical pulley G, which transmits from the shaft E power which operates the carriages. The boxes or bearings H, which carry the shaft E, are each pierced by one of the rods B of the main frame and are secured in place by a collar and set-screw J, clamping on the rod. G is another conical pulley arranged with its taper disposed oppositely to that of the pulley G, and these pulleys are designed to be connected by a belt, by means of which power is transmitted from the shaft E to operate the carriages. This belt by means of a lever near the operators hand can be moved backward or forward on the pulleys to regulate, as may be required, the speed of travel of the carriages as compared with the speed of the saw. This lever forms no part of the present invention and has been omitted from the drawings for the sake of clearness. The shaft P, which carries the conical pulley G, is mounted in suitable bearings N N on the framework of the machine, in this instance by shafts L L, of angle-iron, fastened securely to the top rods of the main frame and curving up at the back of the machine to form bearings for the crank-shaft M.
Q Q are castings each with two upright arms in which slide the reciprocating bars R R, which drive the carriages. These castings rest upon and are bolted to the angle-bar L and have also an arm running down at the back of the machine, fastened to the bars of the main frame.
On one end of the crank-shaft M is a beveled friction-wheel S, which cooperates with a smaller beveled friction-wheel S on the end of the shaft P and by means of which the crank-shaft M is operated. On this crankshaft M, as shown in the drawings, the cranks are one hundred and eighty degrees apart. If three carriages are to be employed, the cranks would be placed one hundred and twenty degrees apart, and if four carriages are used the cranks would be ninety degrees apart, and so on.
.to the front rods of the main framework of the machine.
V is a brace of angle-iron connecting all of the slides U, while V represents angle-bars which support the guides K, which serve to keep the saw in place.
W W are the carriages which carry the block to be sawed between the tooth-rollers it h backward and forward over the saw. At each end of the stroke the thickness of one shingle is fed to the saw, a butt being fed to one side and a top on the other at the same time and the reverse at the other end of the stroke. The ratchet set-works at each corner of each carriage which accomplish this are shown in detail in Figs. 5, 6, 7, and 8. In these views, crepresents wedges adapted to be adjusted and kept in position by the screws OZ.
g is a casting bolted to the end of the slide and carrying the wedges.
eis a pin having one end bifurcated, as seen in Fig. 5, and in this bifurcation are pivoted a plurality of dogs f, adapted to engage the ratchet-wheel h on an extended end of the roller 7L.
m is a spring around the pin a, inclosed within a housing m, having one end engaging the inner end of the housing and the other engaging a pin m disposed transversely of the pin a, as clearly shown in Fig. 8.
As the carriage having crossed the saw approaches the end of its stroke, the pin 6 strikes the wedge and is forced back and by means of the dogs f rotates the ratchet-wheel h, thus rotating the tooth-roller it, and, according to the adjustment of the wedge, a butt or a top is fed to the saw. As the carriage returns across the saw the spring m forces the pin and dogs back ready for the next setting.
X is a bracket attachedto each of the carriages, by which the same is connected with or disconnected from the reciprocating bar R, which drives it.
It is shown in detail in Figs. 9, 10, 11. When the carriage is in operation, the bar R fits in a notch at the top of the bracket, and they are locked together by means of a cross latch-bar Y, which is hinged to the bracket and drops down into a notch in the bar R, as shown. 7 When this latch-bar Y is thrown up by the operator, the reciprocating bar and the carriage are disconnected and the carriage stops.
Z is a casting having a boss through which passes a rod (0, which is adapted to be used in shortening or lengthening the machine. The other end of the rod (4 passes through a casting n, which supports the sway-bar which carries the shaft F of one of the large sawpulleys.
I (see Fig. 3) is a line-wheel for adjusting the face of the large saw-pulley so that the saw will run true. This is an ordinary provision in this class of devices.
O O are guards placed at the back and around the ends of the large saw-pulleys F F, as seen clearly in Fig. 1, in which view they have been partially broken away in order to show the structure behind, and in the other views they have been omitted for the sake of clearness.
What is claimed as new is 1. In a shingle-cutting machine, the combination with a double-edged band-saw arranged horizontally, and a pair of carriages mounted to slide horizontally above the saw, of slides on which the carriages run, angle-irons supporting said slides, a brace connecting all of said slides, a bracket on each carriage having a notch, a reciprocating bar for actuating each carriage detachably engaged in said notches, a hinged latch-bar on each carriage to lock said bar in its notch, guides for said bars, a crank shaft and connections between said crank-shaft and the reciprocating bars to reciprocate the latter alternately in opposite directions.
2. In a shingle-cutting machine, the combination with the frame, of angle-irons secured to said frame and curved upwardly at the rear of the machine to form bearings, a crankshaft mounted in the hearings in the upper ends of said angle-irons, in the curved portions thereof, castings with upright arms secured to said angle-irons, carriages, reciprocating bars connected therewith and guided on the upright arms of said castings, and pit- IIO men connecting the crank-shaft with the said reciprocating bars, and a double-edged band- WILLIAM THORP.
