SHINGLE-IV IACHINE.

SPECIFICATION forming part of Letters Patent No. 415,098, dated November 12, 1889. Application filed June 26, 1889. Serial No. 815,845. (No model.) Patented in Canada September 5, 1888, No. 29,820.

. in Shingle-Machines, (for which Letters'Patent were granted to me in the Dominion of Canada under date of September 5, 1888, No. 29,820;) and I do hereby declare that the following is a full, clear, and exact description of the invention, which 'will enable others skilled in the art to which it appertains to make and use the same, reference being had.

slabs of different widths; further, in. providing-suitable mechanism whereby the gage or thickness of the shingle is adjusted; further, in providing suitable means for adjusting the thickness of the shingle at either end of I the same, and, furthermore, in various other details of construction, as will be hereinafter more fullyset forth and described.

In the accompanying drawings, the letter A indicates the frame of the machine, and B the cylindrical pulley drum, having mounted therein and turning in unison therewith a vertical shaft 0, said shaft carrying on its upper end a slicing-saw l).

1 The upper forward portion of theframe of the machine is provided with longitudinal ways or tracks E E, one of said tracks being preferably provided with an upwardly-extending flange F. A hand-carriage G is reciprocated in these tracks or ways, one side of said carriage being provided with laterally-extending hooks H H, which fit over the upwardly extending flange F of the track, and the opposite side is provided with curved lugs I I, which fit over the top portion of this side of the track. The hand-carriage is also provided on each sidewith laterally-extending lugs adapted to fit under the extended portions of the tracks, thereby retaining the carriage securely in position on the frame.

ZMounted in suitable bearings J J, secured to the top of the hand-carriage on one side thereof, is a shaft K, encircled by a collar L, said shaft having secured thereto one end of a spring M','the other end of said spring being secured to a strip Nin the frame to the rear of the shaft. This shaft is also provided with crank-arms O O, which are pivotally connected to arms P P, said arms in turn being pivotally connected to a reciprocating dog Q, said dog sliding in ways R, secured to the end pieces of the frame. This shaft is also provided on its forward end with a crank-arm S, pivotally secured to a link T.

Secured in a bearing U upon the upper side of the end piece'of the frame is a short shaft V. A collar WV is rigidly-secured to this shaft, and is provided upon its upper portion with a lever X and upon its under portion with an inclined arm Y, which is pivotally secured to arm T. It will be seen that when the lever is depressed the connecting arms and the crank upon the end of the shaft K will cause the dog to be moved forward in the ways, the coiled spring secured to the same havinga tendency to retract or draw back said rack-bar when the same is not held in engagement with the block to be shingled.

Mounted in suitable bearings Z Z in the frame of the machine is a shaft A, having rigidly secured to one end thereof a lever B, said lever being provided on its upper end with a spring-pawl O. A notched quadrant D is loosely mounted upon this shaft and bears against the inner side of the lever. The

shaft A is also provided with crank-arms E E, having pivoted thereto links F F.

A second cross-shaft G is journaled in suitable bearings H H to the forward portion of the frame of the machine, and is provided on one end with a crank-arm I, said arm having pivoted thereto an arm J, havin g its forward end screw-threaded. This arm is encircled by one end of a collar K, provided with interior threads, the opposite end of said collar having secured therein the reduced end of an arm L, the other end of said arm being pivotally secured to the lever B. This shaft G is also provided with oppositely-arranged cranks M M, similar to the cranks upon shaft A, and having pivoted thereto links N N.

The vertically-reciprocating frame is reprcments and adapted to retain the bolt-s in secure position within the perforated enlargements of the longitudinal pieces Q Q. These bolts are provided on their lower ends with fiat heads adapted to be pivotally secured to the links F and N, respectively, of the shafts A and G, said links connecting the arms or cranks of the shafts with the bolts. By this arrangement it will be readily seen that when the lever B is moved it carries with it the shaft A and also the shaft G by reason of the connecting mechanism already described. On the forward stroke of the lever, therefore, the cranks upon the respective shafts A and G are turned downward, which, through the pivoted links secured to the bolts passing through the enlarged perforated ends of the reciprocating frame, will give a downward movement to said frame. On the reverse stroke of the lever the reciprocating frame will necessarily be moved upward in its grooves or ways.

Extending from one side of the front portion of the frame is a bearing-plate V, provided with a sem i-cylindrical recess. Adapted to be secured to this bearing-plate, by screws or other suitable means, is a cap W, provided with a similar recess, thus forming, when in position, a complete circular bearing. A

hand-wheel X is provided with an inwardlyextending hub Y. This hub has a central screw-threaded hole or aperture Z, said hole also extending through the center of the wheel. The hub is journaled in the bearing formed by the laterally-extending plate and its appropriate cap, and is provided with collars A A thus preventing said hub from lateral displacement within its bearing. The screw-threaded end of an arm 13 passes into the hollow hub of the hand-wheel, and has its other end pivotally secured to a short shaft 0*, extending from the inner side of the notched quadrant. It will be seen that by screwing this hand-wheel to the right the screw-threaded rod will draw the notched quadrant forward, thereby increasing the forward stroke of the lever and permitting the reciprocating frame to descend a greater disr tance than would be the case should the lever have a more limited forward stroke. In this way the thickness of the shingle can be regulated, as it is obvious that the farther the reciprocating frame descends the thicker will be the shingle.

I have before described means for accomplishing the same resnltnamely, the employment of the screw-threaded arm J, e11

. circled by one end of a collar K, provided with interior threads in connection with an arm which is pivoted to the operating-leve1z It is obvious, however, that in some cases it will be found inconvenient to employ this means, or, perhaps, when the collar is screwed forward it will not decrease the stroke of the lever sufficiently. In this case the hand-wheel above described may be conveniently employed.

Journaled in suitable bearings D in the sides of the reciprocating frame is a reciprocating shaft E This shaft is provided with screw-threaded portions F F adapted to receive interiorly screw-threaded cone-shaped collars G G having their reduced ends pointing toward the center of the shaft. If desired, the shaft may be provided with nuts I1 H to the rear of these cone-shaped collars, holding the same securely in their adjusted position. Another collar 1 encircles this shaft and is provided with a downward bifurcated extension 2' and upon its upper portion with a hole J adapted to receive a screw K to permit of the securing of the collar upon the shaft.

A longitudinal shaft L provided on its forward end with a lever M is journaled in suitable bearings N N upon the pieces Q Q of the reciprocating frame, and is provided, if desired, with a hexagonal collar 0 against which a spring P secured to the front strip of the reciprocating frame, impinges, said collar bearing against the forward side of the front bearing N so as to hold the shaft in proper position. This shaft is also provided toward its forward end with a crank Q to which is pivotally secured an arm R which in turn is pivotally connected to the lower extended bifurcated portion 1' of the collar 1 By this means connection is attained between the longitudinal .shaft and the central reciprocating shaft, so that when the lever M is operated it will give a reciprocating motion to said central reciprocating shaft.

The pieces Q Q of the-tilting frame are provided at their central points with curved recesses or depressions q" q, in which are seated the perforated circular heads of the bearing-plates S S Pivotally secured in these bearing-plates by means of bolts T T are the tilting frames U U Upon these tilting frames are placed crosswise the block or blocks to be shingled, and by this arrangement I am enabled by suitably adjusting the cone-shaped collars upon the central reciprocating shaft to vary the width of either end of the block. For instance, the reciprocating frame, with its connecting mechanism, while adjusting the width of the block as a whole,will not permit of one end being made thicker than the other. If, therefore, it is desired to alter the taper, all that is necessary to be done is simply to turn the shaft L so that the appropriate cone-shaped collar upon the reciprocating shaft will move toward the center thereof until the base of the cone supports the tilting frame. this end of the block, so that when the same meets the saw on the reciprocation of the carriage the same will be considerably decreased, while the opposite end of the block will be correspondingly increased. In thus turning the shaftL in order to adjust the position of the cone-shaped collars said shaft is held in its turned position by reason of the pressure exerted by the spring P upon the hexagonal collar 0 It will be found, however, that in adjusting these cone-shaped collars so that one end of the shingle may be made thinner than the other the opposite end will sometimes be made thicker than is desired. To

provide against this I have shown the side pieces of the reciprocating frame provided with recesses g g (1 said recesses having their bottoms inclined or beveled. Disposed between these side pieces of the reciprocating frame, and seated within the beveled recesses q 'thereof, are yokes. V V having latorally-extending ends '0 v said ends being inclined or beveledupon their under sides to register with the bevels of the notches. The forward downwardly-flanged ends of these yokes are also provided with holes for the reception of screws W which, when screwed inward, will impinge against the side pieces of the reciprocating frame and necessarily force the yoke to climb the inclines and raise said yoke, whereby the supporting-frame is also necessarily raised or elevated, thus readily adjusting the device in orderto, overcome, when desired, the cutting of one end of the shingle too thick, by reason of the adj ustment of one of the cones in order to decrease the thickness of the opposite end of the block. The forward end of the frame is also provided with a stop X against which the car- This will necessarily raise riage bears when brought back from engagement with the saw, thereby preventing the dog may be made to engage the sameby 1 simply operating the lever hereinbefore described. The width of the shingle to be sawed is now adjusted by means of either the handwheel or the arms, screw-threaded sleeve, and crank upon the end of shaft G. The next step is to adjust the butt-end of the block to be shingled by means of the cone-shaped collars, as hereinbefore described,v the spring bearing upon the hexagonal collar holding the longitudinal shaft in its turned or adjusted position, and if, as stated, one end of the shingle should thereby be thicker than desired, this difficulty may be obviated by the yokes V in connection with thelongitudinal shaft suitably connected to the central reciprocating shaft.

What I claim more especially as the particular advantage of this machine is the ease and readiness with which the different parts of the same are adjusted and regulated.
