SHINGLE MACHINE.

SPECIFICATION forming part of Letters Patent No. 469,976, dated March 1, 1892. Application filed November 5, 1888. Renewed June 20, 1891- Serial No. 396,895. (No model.)

4 siding at Grand Rapids, in the State of Michigan, have invented certain new and useful Improvementsin Shingle-Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to shingle-sawing machines; and the object of the invention is of the frame.

tails hereinafter referred to.

.to improve the various parts of the machine.

The invention most particularly relates to im provements onhand-feed shingle-machines in the mechanism for operating the tilt-table of a shingle-machine and also the bolt-supporting surface of the tilt-table, also the boltcarrying carriage and the dogging mechanism of ashingle-machine. s

Figure 1 is a perspective of the shinglesawing machine. Fig. 2 is a top plan of the machine with parts broken away. so as to better illustrate certain details. Fig. 3 is an under side perspective of one corner of the carriage. Fig. 4 is an end view of carriage-supporting track. Fig. 5 shows a face andside view of the rocking arm, and Fig. 5 a side view of one of the fingers which engage rack on the carriage. Fig. 6 is an elevation of part Fig; 7 isan elevation of de-. Fig. 8 is an end elevation of parts of the machine. Fig. 9 is an .end elevation, with parts omitted, of the tilt-actuating mechanism. Figs. 10 and 11 are detail elevations of ratchet-wheels, which may be used in connection with the tilt.

This shingle-machine is of the same gen-. eral typeof hand-feed machines as described in Letters Patent to Willis J. Perkins, dated March 31, 1885, No. 314,603.

Thetilt-table used on this machine is fully described in patent to WVillis J. Perkins, No. 236,620, dated January 11, 1881, excepting the roller-bolt bearing-s11 rface and method of operating hereinafter described. Tilting mechanism has heretofore been applied to handfeed machines; but in all such devices with which I am familiar the carriag has to be brought backto aixed point before the tiltingmotion was completed, thereby requiring extra exertionofthe operator and consequent lossoftime. Inthle following-described movement for operating the tilt the above objection is-overcome. H r 1 I .on which the pins 0 c impinge.

carriage. 71 will gradually lift the finger 0 out of enrack-bar b attached to one side. Two rocking fingers c o are supported on the frame in a manner which will now be described. An

arm g is pivoted to the part h of the frame and can rock on the pivot e in the direction of the movement of the carriage. Lugs g on this arm support the pivot f, which carries the fingers 0 0. These fingers or catches c c are drawn toward the bar 9 by springs 1;, attached to lugs or projections 0 and c on the fingers and on the arm, so that the fingers c 0 will be drawn by the springs into engagement with the rack-bar b. The ends of the teeth of the rack -'bar should be inclined, as shown, and the adjacent sides of the spring-fingers are also beveled or inclined, (see Fig. 2,) while the outer faces of these fingers are at a right angle to the line of movement of the carriage. Consequently one of the fingers will, oppose a resistance to the movement of the carriage in one direction and theother in the other direction when in engagement, but both may rock out of engage ment with the teeth of the carriage. The fingers c 0 have inwardly-projecting pins 0 0 Frame h has two inclines or cam-bearings h h Now, referring to Fig. 2, when the carriage is moved toward the saw the first tooth of rack 19 will engage finger o and swing said finger and its arm g in the direction of movement of the The pin c bearing on the incline gagement with the rack-teeth, and thecarriage will thencompiete its movement without further rocking the arm finger c sliding along the rack-teeth. On a reverse movement of carriage and rack b the finger 0' will be engaged by the rack-teeth until its pin 0 bearing on the incline h, is lifted free of the rack-teeth. Thus the reciprocation of the carriage through a long path will swing the arm g buta short distance, determined by the cam-surfaces h 7L2. pivoted thereto, the free end of the pawl engaging the teeth of a ratchet-cam j, which is journaled to a stud or bar h of the frame.

'In hand-feed machines the operator has to propel the carriage back and forth by sheer force of muscle, therefore by lightening it the The carriage therefore has two side pieces a a, preferably made of wood. Stationary dog r is bolted to them. The movable dog 'r' has sliding bearings on metal pieces or binding strips 8, Fig. 3, a recess 3 being cut in the carriage side a, forming the seat for slide bearing the dog 7'. The tiet connects the two ends of sides a a, and is bolted solid to sides a, a. Tiet is turned up on the ends, sleeve-bearings t, fastened thereto, forming j ourn al-seats for dogging-rod z. Sliding bearing '0 is formed partially out of the, dog-seat s, the piece 5' being turned down to present a bearing-face for slide-rail 0a m and completed by right-angle bearingy. Part of bearing g has an inwardlyextending projection 11/, which. fits into groove 00' on slide-railsc 0c. The carriage a a is thereby locked on the sliderail 0: 0c and cannot be thrown off the rail onto the saw.

A further object of my improved carriage is to meet the wants of manufacturers that are making dimension shinglesthatis,shingles of uniform widths. The standards of shingles now adopted and manufactured extensively in certain sections of the United States are respectively four inches, five inches, and six and one-half inches. It is with present methods employed very difficult tocrosscut shingle-bolts from the log of exactlength. It is also a waste of time to saw shingles with one narrow bolt in the shingle-machine carriage at atime; thereforel have adapted th'is carriage to hold from one to three shinglebolts of varying lengths, as now about to be described. a-shingle-bolt having an irregular doggingsurface or a number of shingle-bolts 0t uneven length or dogging-surface are to be held in one carrier, carriage, or compartment the grasp of the dog or dogs on the bolts must be very firm and solid. The dogs must be able to support or carry the bolt or bolts or spalts thereof over an open space--such as the space between the end of the tilt-table and the edge of the saw or other. space where there is no supporting way for the bolt to ride on'and the weight of the bolt or the jar of the machine or other accidental causemust not loosen the hold of the dogs. The dogs must only loosen the bolts when they are expected to do so, if good results are desired.

The principle of the auxiliary dogging mechanism is applicable to shingle-sawing machines and block-sawing machines of. different construction, either reciprocating or rotary, and hence I do .not limit myself to the application of this part of my invention to this particular'form'of shingle-machine or for It must be understood that where be used at the other end of the block without departing from my invention. labor of handlingis proportionatelydecreased.

Referring to Fig. 2, and especially tothe .detail, Fig. 3, one dog 7" is of usual or any approved construction, as with a series of holding-teeth arranged side by side and shown in ,line with each other and near one end of the carriage. The other dog r has a series of holders or biting-teeth r which in some measure partake of the movement of the main dog 1*, but have also an independent movement.

Fig. 3 shows the dog-teeth or holders r as movable in bearings in the main dog 0". A spring to, connected to some part of the main dog, acts on each tooth or holder 7' to press said tooth or holder forward, the dog r sliding in ways in the body of the main dog 0". The movable dog 0 ismoved forward or back by any suitable train of mechanism common for the purpose. As shown, this general movement of the dog is effected by the following train of mechanism. The dog r is mounted on or carried by the supportrfl and the springs to are mounted on the support r which supports partake of the movement of and are preferably part of the main dog. A link 7* connects the dog r to the lever Z2 on the shaft. Consequently the rockin g of the shaft z throws the entire dog 0" forward or back, with a tendency to engage with the bolt or bolts, which may be between the dogs r/r';

but as dog-teeth or holders 1' have a move ment independent of the dog r they will adjust themselves to' the ends of the bolt or bolts in the carriage, as many teeth or holders r engaging the end of a bolt or bolts'as the width of the bolt or bolts will warrant, andeven if the bolts are irregular in length or of irregular dogging-surface (within usual limits) the compound dog will adjust itself to engage and hold firmly the bolt or bolts in the carriage. The springs to have one bearing against the dogs or teeth r and the other against a piece which pal-takes of the move ment of and virtually forms part of the main dog 0".

High bolts are apt to tip when being sawed. To prevent this, I have placed the guides or gages z .2 a .2 on front side of carriage, against which the bolt may be held by the operator while sawing, he employing one hand, as a rule, to handle the carriage with.

It will be understood that the spring-fingers constitute a clutch-trip, which makes engagement between the carriage and the tilt-operating train of mechanism, and'that said trip has this peculiarity of movement, that it is operative with thetirst movement of the carriage in either direction, and after it has been -in' operation long enough to actuate the tilt it becomes automaticallyinoperative, no matter what the movement of the carriage may be."

It will thus appear that the trip has a variable relation to the carriage and operates antomatically, whether the carriage be reciprocated a long or short distance. This I find a very important feature of the machine. Thus, suppose the operator desires to saw shingles from a narrow bolt-say four inches wide the edge of the shingle-bolt is near the saw before the movement of the carriage begins.

[O The operator presses the carriage and bolt toward the saw, and,as soon as the shingle is sawed from the bolt, reverses the carriage. The clutch will be actuated to move the tilt precisely as if the carriage had made a long travel-as for an eight or twelve inch shingle- -boltor a number of narrow bolts. Thus the operator is not compelled to make a full reciprocation of the carriage in order to actuate the tilt, as in all other machines with 1.
