' To all whom it may concern.-

shingle-sawing machines.

The object of the present invention is to improve the construction of shingle-sawing ma- 1 parts hereinafter chines and to provide a simple and comparatively inexpensive one which will be adapted to cut rapidly shingles of a uniform thickness and in which the carriage will be securely held against lateral movement.

A further object of the invention is to provide a shingle-sawing machine of this character adapted to be used in connection with any ordinary saw for cutting slats or ripping lumber and capable of automatically shifting a shingle-block as it is advanced or fed forward, whereby the shingles will be cut from the block with their thick ends alternately at opsite ends of the same.

A-further object of the invention is to enable the shingle-block to be held without liability of losing or Wasting any of the material.

The invention consists in the constructionand novel combination and arrangement of fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective view of a shingle-sawing machine constructed in accordance with this invention. Fig. 2 is a vertical sectional view taken longitudinally of the carriage. Fig. 3 is a detail sectional view illustrating the constructionfor locking the laterally-movable shingle-block-carrying frame against forward movement when the oscillatory actuating device is'elevated. Fig.-

4: is a similar View illustrating the construction of the slides and showing the arrangement of the spring for actuating the laterallymovable shingle-block-carrying frame to set the same in a plane parallel with the rails preparatory to applying a shingle-block to it.

Like numerals of reference designate correverse movement, and a (No model.)

sponding parts in all the figures of the drawlugs.

1 1 designate a pair of rails connected by a suitable cross tie 2 and having oppositely-beveled upper faces, forming an apex and presenting inclined inner side faces 3, to which is secured bars or strips 4, which project outward and upward beyond the apexes of the tracks and which are arranged to be engaged by hooks 5 of slides 6 of a carriage 7. The slides, which are thus interlocked "with the rails, consist of transverse metal plates secured to the bottom of, he I looking the carriage and the rails in this manner the former is securely held against transuniform thickness of shingle is thereby insured. The sawmill-carriage, which moves longitudinally of the rails to carry a shingle-block against a saw, is provided with longitudinal beams 8 and 9, and it has transverse bars 10 and 11, secured to the beams 8 and 9 at the ends thereof and provided at their upper faces with metal bars or plates 12, having inwardly-projecting longitudinal carriage 7. By interedges, forming flanges and providing Ways for slides 13 of a laterally-movable shingle-blockcarrying frame 14:. The guide-bars 10 and 11 are suitably secured to the longitudinal beams 8 and 9, and a handle bar 15 is secured to one of the guide-bars 11 by means of brackets 16. The brackets 16, which are arranged at the ends of the transverse handle-bar 15, areapproximately U shaped, being composed of two sides and a transverse connecting portion. The sides are secured at their lower ends to the said guide-bar 11, and the transverse connecting portion is curved to conform to the configuration of the handle-bar.

Each slide 13 consists of a horizontal bar located at the bottom of the laterally-movable shingle block carrying frame and provided with an arm 17, extending upward from one end of the bar and rigidly secured to the frame 14. The arm is provided with opposite notches 18 to receive the inwardlyprojecting flanges of the guidebars 10 and 11, the slide-bar being located beneath the flanges, whereby the laterally-movable shingle-blockvcarrying frame is unlocked with the sawmillcarriage. Each slide is supported by braces 21 and 22, which are secured at their upper ends to the upper edge of the head-block. The brace 21 extends longitudinally of the slide, and its lower end is riveted or otherwise secured to the bottom slide-bar 13.

The brace 22, which diverges upwardly from the brace 21, is provided at its lower end with a slot 24 to receive the fastening device 25 to secure the braces together. The slot permits a limited movement of the braces on each other at their point of connection to permit the head-block of the laterally-movable frame to have the necessary play to enable it to be arranged at an angle to the plane of the rails to set the shingle-block in proper position for a shingle.

' The slide 13 is subjected to torsional strain at the point of its connection with the arm 17 and serves to assist in returning the frame toa central position after the latter has been released from the position to which it is adjusted during the sawing operation.

The laterally-movable shingle-block-carrying frame consists of the head-block or body portion 20, which rests upon the guide-bars of the sawmill-carriage frame and has connected to it, at the bottom thereof, by hinges 26 a hinged oscillatory actuating and locking device 27, consisting of a bar or body portion provided with an arm 28, extending rearward from the center of the body and supporting one end of a handle 29. The handle 29 is supported by brackets 30 and 31, constructed similar to the handle-supporting brackets 16 and composed of sides and connecting transverse portions, which are curved to conform to the configuration of the handle, which is round.

Mounted on the oscillating actuating device at the ends of the body portion is a pair of pawls 32 and 33, pivoted at their upper ends and curved downward and rearward, as clearly shown in Fig. 1, and provided at their lower ends with engaging portions, which are adapted to engage teeth of ratchet-bars 34 and 35. The ratchet-bars 34 and 35 are each provided with teeth 36 and 37 of unequal length arranged at regular intervals, the teeth at one side of the laterally -movable frame being staggered with relation to the teeth at the opposite side or arranged between the intervals. The teeth at one side being located opposite the intervals and out of alinement with the teeth of the opposite side are adapted to hold one of the pawls in advance or in rear of the other, whereby when the actuating device is swung downward to advance the laterallymovable frame and to force the pawls against the teeth the engaging end of one of the pawls will be in advance of the other and the head-block of the laterally-movable frame will be set at an angle to the plane of the saw, and thereby held in proper position for cutting'a shingle. The pawls may be springactuated or gravity acting, and when the hinged actuating device is swung upward the pawls are thereby carried forward on the ratchet-bars, one of the pawls being carried to aposition slightly in advance of one of the long teeth of the adjacent ratchet-bar, and the other pawl being carried to a position slightly in rear of the engaging face of the corresponding large tooth of the other ratchet,

whereby when the actuating device is swung downward one pawl will engage the large tooth of one ratchet-bar and the other pawl will be carried rearward slightly and into engagement with one of the small teeth of the adjacent ratchet-bar. The head-block or body of the laterally-movable shingle-block-carrying frame will be firmly locked at an angle to the plane of the saw. When the hinged actuating device is swung upward, the rear pawl or dog will be carried in advance of the large tooth of the adjacent ratchet-bar, and when the actuating device is swung downward the position of the head-block or body of the shingle-carrying frame will be reversed. The ratchet-bars are suitably secured to the inner guide-bars 10 and are offset therefrom, the

ends of the ratchet-bars being preferably bent at an angle to form attaching portions or arms. The ratchet-bars are connected at intervals between their ends with the guide-bars 10 by suitable fastening devices, preferably consisting of bolts 38. The engaging ends of the pawls are recessed slightly to enable them to straddle the ratchet-bars toprevent lateral disengagement of the pawls or dogs.

In order to lock the laterally-movable shingle block carrying frame against forward movement to prevent any shifting of the same, the actuating device is provided at the outer or rear end of its arm with a depending pin 39, which is located above a series of staggered socket openings 40 of a bar or plate 41, andthese sockets are located alternately at opposite sides of the center and are arranged to receive the pin of the arm which cooperates with the locking dogs or pawls to hold the laterally-movable shingle-block-carrying frame rigid with the sawmill-carriage during the sawing operation. The plate or bar 41 is secured to a, pair of parallel supporting bars 42, having enlarged intermediate portions 43, which form shoulders for engaging the inner faces or edges of the side beams of the sawmill-carriage, and they are secured to the same by means of pivoted latches 43. The pivoted latches 43, which are approximately U-shaped, are suspended from the inner faces of the bars 42 and engage pins or projections 44 of the side beams of the sawmill-carriage. By this construction the transverse bar or member 41 is detachably secured to the sawmill-carriage. The pin of the arm of the actuating device extends downward into the space between the bars 42; but the transverse bar or member 41 may be provided with and located above and arranged to engage a ratchet of the plate or member 41. The ratchet 47 consists of a series of shouldered teeth formed by recessing the bar or member 41 at one side thereof; but any other form of ratchet may be employed. The locking device is resilient to enable it to yieldingly engage the ratchet, and it is adapted to prevent the laterally-movable frame from advancing when the actuating device is swung upward. WVhen the actuating device is swung downward, the resilient locking device or dog 45 is lifted out of the ratchet and the shingleblock-carrying frame is permitted to advance,- as before described.

The pawls or dogs 32 and 33 are positively clamped in engagement with the ratchet-bars by means of locking-arms 18, fixed to the body portion of the actuating device adjacent to the ends thereof and provided with laterally extending portions located above and adapted to engage the pawls or dogs 32 and 33 at the upper faces thereof. These looking-arms will prevent the pawls or dogs from being accidentally thrown out of engagement with the ratchet-bars by any vibration or jar of the machine.

When it is desired to move the shingle-blockcarrying frame rearward to apply a block to the same, the pawls or dogs 32 and 33 are locked in an elevated position by means of a pair of reciprocating rods t9 and 50, mounted in suitable guides 51 of the actuating device and connected at their inner ends with an operating-lever 52 and adapted to be projected outward beneath the pawls or dogs 32 and 33 when the actuating device is depressed and in engagement with the transverse bar or member 41. When the reciprocating rods are thus engaged with the pawls or dogs, the actuating device when swung upward will carry the said pawls or dogs out of engagement with the ratchet-bars. The lever 52, which is pivoted between its ends, is provided at its upper end with a suitable handle, and the inner ends of the locking-rods are connected with the lever 52, at opposite sides of the fulcrum thereof. The lever 52, which is arranged in an upright position, is preferably pivoted to the body portion of the actuating device, at one side of the arm thereof, and the rod is angularly bent to clear the said arm.

The shingle-block is secured to the headblock of the laterally-movable shingle-blockcarrying frame by means of fixed

clamps

53 and 54 and a movable clamp. The fixed clamps 53 and 54 consist of plates secured to the head-block, at the bottom thereof and at a point adjacent to the top of one end .of the same, andthese plates have .ofiset engaging portions or jaws provided with teeth and adapted to be embedded in the shingle-block without injuring the same. The adjustable clamp consists of a pair of upright guide plates or bars 55, located at opposite sides of a recess of the head-block and terminating at their lower ends in jaws 56, and a movable slide 57 arranged between the guide plates or bars and provided with an upper clampingjaw 58. The vertical guide plates or bars 55 form a way, and the stationary jaws 56 are arranged at the bottom thereof. The slide consists of a vertical plate arranged in the way and provided with a block or piece 60, arranged between the guide plates or bars and fixed to or formed integral with the plate or body portion of the slide. The upper jaw, which engages the top of the block, consists of a plate or piece centrally connected with the slide and having outwardly-offset side portions arranged toclear the guide plates or bars and provided with depending engaging portions or teeth, which are adapted to be embedded in the upper face of the shingle-block. The slide is connected by a link 61 with an operating-lever 62, fulcrumed at one end on the head-block and connected between its ends with the said link and'adapted to be readily operated to force the movable jaw of the clamp into the shingle-block. By this construction the shingle-block is securely clamped to the head-block or body portion of the laterallymovable shingleblockcarrying frame without wasting or spoiling any of the material.

When a shingle-block has been secured to the head-block or body portion of the laterally-movable frame, the same is advanced by oscillating the actuating device, which feeds the head-block forward by a step-by-step movement, which alternately arranges the shingle-block with its inner face at an angle to the plane of the saw, and the said shingleblook is changed from one position to the other, so that the shingles will be cut with their enlarged ends alternately at opposite ends of the block. The forward movement of the shingle-block-carrying frame is limited by projections or pins 63 and stops 64 to prevent the said frame from coming in contact with the saw. The pins or projections 63 depend from the head-block and are arranged between the transverse guide -blocks of the sawmill-carriage, and the stops consist, preferably, of transverse pins or fastening devices, which extend across the spaces between the guide-bars 10 and 11. After the actuating device is operated to arrange the block in position for sawing a shingle the carriage is moved longitudinally of the rails to carry the shingle-block against the saw. The handle of the actuating device and the handle of the carriage are arranged in convenient position to enable them to be simultaneously grasped by the operator.
