SHINGLE -MACHINE Specification of Letters Patent.

Patented April 21, 1908.

To all whom it may concern:

Be it known that I, GEORGE W. DORMAN, a citizen of the United States, residing at Everett, in the county. of Snohomish and State of 'ashington, have invented a new and useful Shingle-Machine, of which the following is a specification.

The invention relatesto improvements i shingle machines.

The object of the present invention is to improve the construction of shingle machines, and to provide a sim le, inexpensive and eilicient machine capab e of automatically feeding a shingle block to the saw, and of cutting the shingles with the tips and the butts alternately at the top and bottom of.

the block.

'A further object of the invention is to provide a machine of this character, which, when there is a knot, or other im ei'l'ection in a shingle block, nearer to one en( than the other of the same, will be capable of cutting the shingles so that the knot or other iin perfection will continuously occur at the tip or thin end.

With these and other objects in view, the invention consists in the con-struction and novel combination lof, parts hereinafter fully described, illustrated in the accompanying drawings, and ointed out in the claims hereto apqpende it being understood that various c anges in the form, proportion, size and minor details of construction, within the scope of the claims may be resorted to Without departinr from the spirit or 'sacrificing an of the advantages of the invention.

The .main frame is provided with an upwardly extendinv substantially rectangular portion2, and it 1s provided at the top and bottom thereof with longitudinal guides or ways 3 and 4, preferably consisting of projecting flanges and receiving a reciprocatory carriage 5. The carriage 5, which is provided with the means hereinafter described for clam ing a shingle block, is movable toward and circular s w 6. The bottom of the carriage is provider at its ends with integral casings 7 in which are mounted grooved rollers or wheels 8, and the latter run upon the flange of the bottom guide or way 4, which formsa track for the carriage. The top of the carria-ge is provided with a longitudinal groove 9 to receive the flange of the upper guide or way 3. end nearer the saw, isconnected by a suitable pivot 10 with one end of a connecting rod or ar 11, which extends to the upper end of an oscillatory -lever 12, and which is connected with the same by a suitable pivot 13. The ends of the connecting rod or bar maybe secured to the carriage and to the oscillatory lever in any lesired manner. The said lever is fulcrumed\at its lower end on a suitable pivot 14.

The oscillatory lever is actuated by an eccentricallyarranged pivot or wrist pin 15, mounted on an arm of a gear wheel 16 and forming a crank element. The eccentrically arranged pin or pivot 15 passes through a suitable opening of a slide 17, consisting of a block and movable longitudinally of the oscillatorylever 12. The slide 17 which may be constructed in any desired manneigis provided with a suitable opening to receive the oscillator lever, and it slidably connects the same wit the gear wheel 16.

The gear Wheel 16, which is keyed or other- 1 designates `wise secured to a shaft 18, meshes with a Oma'.

The inner end of the carriage, or the and to be provided with means for Llo ' {.ardmovement of the upper shingle block rection.

the saw arbor or shaft to the gearing, which oscillates the lever 12, and the latter actuates the carriage and the means hereinafter described for feeding the shingle block.

The shingle block is yieldably clamped between up er and lower rolls 26 and 27, pro-- vided wit spur teeth arranged at intervals, as shown, and adapted to grip the upper and lower faces of the shingle block. The spur teeth, which are arranged in annular series, project beyond the body portion of the rolls. 1 he lower roll 27 is journaled in suitable bearings of. the reciprocatory carriage at the bottom thereof, and the upper roll 26 is mounted in suitable bearings of a hinged clamping frame or member 28, which is provided at its ends with arms 29. Theparms 29 are provided with suitable eyes or openings for the reception of a c horizontal pivot or pintle rod 30, which is adjustably mounted on the carriage, the latter being provided with a plurality of ears or bearings 3l for the reception ofthe said rod 30. The hinged frameor member 28 is adapted to swing upwardly and downwardly to engage and release a shingle block, and it is connected by a link 32 with a weighted lever 33, which yieldably maintains the roll 26 of the movable clam frame or member 28 in engage mentzwit i the shingle block. The downengaging roll is limited by a keeper 33a, monnted at the tbp of the carriage and re- ;'c'e'iving the weighted arm of the lever The lever 33, which is fulcrumed at anintermediate point by a bolt 34, or other suitable i fastening. device, is provided at one of its arms with a weight 35, and its other arin is angularly bent and is connected by a rod 36 with afoot lever or treadle 37 The weighted i leveriSS is located above the hinged frame or member 28, and when the foot lever or treadle 37 is' depressed, the weighted arm of the' lever 33 and the hinged traine or member are raised. vThe weight is adapted to carry the upper engaging roll' 26 automatically into enga-gement with the shingle block, when the foot is removed from the lever or treadle 37. The foot lever or treadle 37, which ent-endsI longitudinally of the machine,

` isvfulcrumed at its inner end on the saw,=and 'ng-rod 36 is secured at its lower end to the lever or treadle 37y at a ends thereof.

The up er and lower rolls are reversely rofed the shingle block forwardly or point between the roll -being moved forwardly or outwardly, .and the to portions of the-lower feed roll 27 beinglsi-mu taneously moved in the same di- The upper and lower feed rolls 26 and 27 are provided -with ratchet wheels 38 `and 39, havingvtheir teeth shouldered in opposite directions. The upper ratchet wheel 38 is engaged by an adjustable pawl or dog 40 of a bar or member 4l, pivotally connected at its inner or rear end 42 with an upwardly extending arm of an upper bell crank lever dei. The outer'end of the bar or inember Ll1 is provided with an enlargement. or head 48 provided with a terminal pivot eilt), receiying an antiffriction rbller or wheel 50. When the arm 4S is swung upward by the means hereinafter desci'ibed,`tlie bar or member 41 will be moved inwardly oi'rearwardly, and the ratchet wheel 3S will be rotated in a direction to feed the shingle block fornnrdly oi' outwardly. After the bell crank lever has been oscillated to feed the upper rolls 26, it is automatically returned toits initial position by'a spring 51, when it is free to return. The` sprin 51 is coiled atA the inner portion of the pivot 47 and its terminals are connected' respectively with the bell crank lever and with a bracket 52 from which the pivot 47 extends. bolted to thc carriage 5, is provided with a )rejecting arm 53 having a threaded opening tor the reception of a vertically adjustable screw 54, which is adapted to support a horizontally extending arm 48. The screw provides means, for adjustably supporting the arm 48, and it thereby limits the return movement of the upper bell crank lever and 4controls the feeding movement.

The lower feed roll 27 is actuated in its feeding movement by means of an adjustable pawl or dog 55, mounted in a slot or opening of a head or enlargement 56 of a bar or member 57. The head or enlargement 56 is bifurcated at the bottom to straddle the lower ratchet wheel 39, and the inner or rear end of the bar or member 57 is pivoted to the lower end of a depending arm 58 of a bell crank le-Y ver 59, fulcrumed at its angle on a pivot 60 ofa bracket 6l, which is bolted to the 'reciprocatory carriage at a bracket 52. The bel crank lever 59, which isactuated -in its return movement by a spring 62, is provided with a substantially horizontal arm 63, having a terminal pivot, which receives an anti-friction roller or wheel 64. The lower bell crank lever is constructed similar to the upper bell crank lever, the only difference being in the arrangement ofthe armshwhereby the barsor members 41 and 57 will be reverselyfactuated to secure the The bracket 52, which is securely oint below the upper y proper rotary, movement of the rolls 26 and 27 to feed .the shingleblock." Theapproxi' mately vertical a'rm 43 of the upper b/ell erank vlever is moved inwardly or backwardly to actuate the upper feed roll, and .the a proximately vertical arm 58 o'f the lowerlbell crank lever is moved forwardly or outwardly to rotate the lower roll 27. The bracket 61 is provided with a horizontally rojectin arm 65, which has 'a threaded perfbration or the rece tion of a verticall.v adjustable screw 66. he screw 66 adjustably supportsthe arm 65 of the lower bell crank lever and composes the feeding movenient of the lower roll.

The bell crank levers are automaticallv operated on the return movement or stroke of the reciprocatory carriage by means of upper and lower arms 67 and 68, disposed longitudinally of the machine in the direction of the movement of the reciprocatory carriage, and pivoted at their outer ends 68a4 and 69 to the upwardly extending portion of the main frame and provided at their inner ends with inclined ortions 70 and 71, located in the path of t e approximately horizontal arms of the bell crank levers and presenting inclined up er faces for engagement with the said anti-friction rollers or Wheels 53 and 61, and forming relatively fixed cams for actuating. the bell crank levers. The arms are connected at an intermediate point to the upper ends of a pair of lifting rods or bars 7 2 and 7 3, which are ap roximately vertical and' which are connected) at their lower ends to levers 74 and 75. The levers 74 and 75 are fulcrumed at their outer ends on a horizontal pivot 76 .of the main frame of the machine, and they are provided at an intermediate point with upwardly extending arms or )o1-tions, which are pivoted to the lower entls of the lifting rods or bars.

The u per and lower arms 67 and 68 are adjustablfy supported at the limit of their downward movement by mea-ns of brackets 77 and 7S, having horizontally projecting .arms and provided at theouter ends thereof with vertically adjustable screws 79 and 80. These adjusting screws assist in controlling the feeding movements of the upper and lower shingle block engaging rolls. The adjusting screws of the bell crank lever and the arms are provided with jam nuts for locking the screws in their adjustment.

-The levers 74 and 75, which swing u iwardly and downwardly, are alternately lifted by an eccentric device, consisting of a pair of disks S1. and S2 spaced apart and mounted on a stub shaft S3, and carrying eccentrically arranged lever-engaging means, which preferably consists of anti-friction rollers or wheels S4 and 85, located res )ectively between the disks S1 and 82, ant at? the inner face of the disk S2 in the space between the same and the main frame. The anti-friction rollers S4 are arranged at diametrically opposite points, and are mounted on pins or pivots S6. The other anti-friction rollers or wheels S5 are located e ui-distant of the anti-friction vrollers or wheetlls Sl, and by this arrangement the lifting levers 74 and 7 5 will be alternately raised, when the eccentric device is rotated.

The eccentric device is rotated b v means of a push rod or bar ST, extending longitudinally of the machine and adjustably connected at its inner end 8S to a short arm St) ol' the oscillatory lever. The outer )ortion of the ush rod or bar is provided with a hook shaped shoulder 90, which is adapted to successively engage a series of pins 91, extending laterally from the outer face of the disk S1 and located at the intervals between the antifriction rollers and wheels S4 and S5. The outer portion of the push rod or bar S7 is slidably supported by a cam slm )ed arm 92 of a shaft 93, and the eccentric tlevice is rotated one quarter of a revolution b v each outward stroke of the push rod or bar, which is adapted to move inwardly or backwardly without affecting the position of the eccentric device. By this partial rotary movenient of the eccentric device, the anti-friction rollers or wheels S1 and are succes-V sively brought to the top of the said eccentric device and are 'aused to alternately lift the levers T4 and 75. When the upper arm 67 is raised by the eccentric mechanism, its cani portion is positioned to increase the feeding movement ol' the upper roll '26, which is thereby partially rotated a greater distance than the lower roll 2T. When in this position the shingle block will be fed outward7 so that the butt olI the shingle will be cut at the top of the shingle block. vWhen the lower arm 65 is raised and the upper arm 69 lifted from the screws T9, as illustrated in Fig. of the drawings, the lower feed roll will be rotated in excess of thc u )per feed roll and the butt of thc shingle blocl the eccentric device is in o )e1-ation, the shingles will he cut from the block with the tips and the butts alternately at the top and bottom of the block. 'lhe short arm SS), which extends upwardly from the lower end of the iscillating lever 1:?, is provided at its upper portion with a slot 94, in which the pivot of the inner or rear end of the push rod or bar S7 is adjustably secured. By raising and lowering the pivot of the inner or rear end of the push rod, the throw or stroke of the same may be varied.

'hen there is a knot or other imperfection in a shingle block nearer to one end than the other, the shingles may bc continuously cut with the knot or imperfection at the tip by throwing the push rod or bar 87 out of operation, when the arms 67 and 68 are in position for feeding the shingle block to cut a shingle with the knot or other imperfection at the tip thereof. This is effected by means of an operating lever 95, secured to the shaft i. ll'hen i lifted and maintained out lof engagement l bar.

` tion of the bra e and the pressure is kregu-l with the eccentric device. The `shaft 93 is jou'rnaled in suitable bearings of a bracket 06, and the outward movement ofthe operating lever is limited by a stop 97 of a curved guiding bar or member 9S. The bracket 96, which is provided at its top with a horizontallydisposed approximately U-shaped portion 99, has an upwardly extending arm. 100,

which is arranged at the. outer edge of the outer portion `of the push rod or bar to pre vent any lateral movement thereof.

The eccentric device .is held against accidental rotary movement by means ofa brake 101, which prevents the eccentric device from being turned too far by the push rod or The brake consists of a curved casting pivot at its upper end 102 by the shaft 93 and carrying a brake shoe 103, which engages the disks ofthe eccentric device. The brake is held yieldablv in engagement with the eccentric device means of a coiled s ring 104', interposed' between a substantial y l.- shaped arm or iece 1,05, and the lower porlated byan adjusting screw 106, which controls the tensionof the spring.
