SHINGLE-MAKING- MACHINE.

Specification of Letters Patent.-

Application filed July 13, 1911.

To all whom it may concern:

Be it known that I, JAMES BARBOUR, a citizen of the United States, residing at Stamps, in the county of Lafayette and State of Arkansas, have invented certaln new and useful Improvements in Shlngle- Making Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in shingle making machines.

One object of the invention is to provide a shingle machine having an improved construction and arrangement of cutting mechanism whereby all of the shingles Will be perfectly formed and by means of whlch a maximum number of shingles may be cut from a bolt of wood and very little if any of the wood wasted.

Another object is to provide an lmproyed construction and arrangement of feeding mechanism and means for adjusting the same whereby the shingles will be cut at the desired thickness and taper.

With these and other objects in View the invention consists of certain novel features of construction combination and arrangement of parts as will be more fully described and particularly pointed out and claimed.

In the accompanying drawings: Figure 1 is a top plan view of my improved shingle machine; Fig. 2 is a side view of the same; Fig. 3 is a similar view of the opposite side; Fig. 4 is a vertical cross section on the llne 44 of Fig. 1; Fig. 5 is a similar view on the line 5-5 of Fig. 1; Fig. 6 is an enlarged plan view of the feed plate and outer portion of the operating mechanism thereof, parts being broken away and in section to more clearly show the construction and arrangement of the dogs for holdmg the blocks or bolts in engagement with the feed plate; Fig. 7 is a cross sectional view on the line 7-7 of Fig. 6, looking toward the outer side of the feed plate.

In the embodiment of the invention I provide a frame or table 1 which is supported at a suitable elevation upon legs 2. In the table is formed a longitudinally disposed opening 3 and in one side of the table is formed a recess 4 the purpose of which will be hereinafter described. Arranged in the opening 3 is a longitudinally disposed knife guiding and supporting frame comprising upper and lower parallel longitudinally disposed guide or track bars 4 connected together at one end by a cross bar 5 and at their opposite ends by a head block 6, said block being held in position by a brace 7 secured thereto and to the top of the table as shown. Slidably engaged with the guide or track bars 4 is a knife carriage 8 in which is secured a knife blade 9, said carriage being adapted to be reciprocated on the track bars by a suitable operating mechanism hereinafter described. "On one side of the blade 9 is arranged a back stop or brace 10 whereby the blade is strengthened and braced.

On one end of the main table 1 adjacent to one side of the head block 6 is a bolt sawlng mechanism comprising a table or platform 11 which is spaced a suit-able distance above and secured to the main table 1 as shown. In the table 11 and adjacent portion of the table 1 are formed saw receiving slots 12 in which is arranged a circular bolt cutting saw 13 whereby the bolts or blocks of wood from which the shingles are formed .are cut or sawed into proper size. The saw 13 is fixedly mounted on an operating shaft 14 revolubly mounted in suitable bearings on the table 1. On the inner end of the shaft 14 is fixedly mounted a band pulley 15 whereby the saw is driven by a suitable operating mechanism hereinafter described. The sawing table 11 is provided with suitable stops and guides to facilitate the holding of the blocks or bolts while being cut by the saw 13.

Revolubly mounted in suitable bearings at the opposite end of the machine from the sawing and cutting mechanism is a drive shaft 16 on the outer end of which is fixedly mounted a belt pulley 17 and on the inner end of which and in the adjacent portion of the opening 3 is revolubly mounted a crank disk or wheel 18. On the wheel 18 is arranged a wrist pin 19 to which is pivotally connected the outer end of a pitman rod 20 the opposite end of which is pivotally connected to the rear end of the carriage 8 of the shingle cutting knife whereby the carriage is reciprocated and the knife thus operated to cut the shingles from the bolt or block which is held in position and fed thereto by a suitable feeding mechanism hereinafter described.

On the shaft 16 is also fixedly mounted a drive pulley 21 which is connected by a belt 22 to the pulley 15 on the saw shaft 14 whereby the saw 13 is driven.

In addition to the power driving pulley 17, I also preferably provide a hand operated driving mechanism comprising a crank shaft 23 which is revolubly mounted in suitable bearings on the table 1. The crank of the shaft 23 works through a slot 24 formed in the table and to said crank is connected the inner end of a right angularly formed operating lever or handle 25 which is slidably engaged with and fulcrumed in a slot 27 formed in a vertically disposed fulcrum plate 28 secured to the table 1 adjacent to one end of the recess 4. The plate 28 also serves as a brace for the adjacent end of the carriage supporting and guiding frame for the cutting blade 9. The outer end of the handle or lever 25 is disposed over the recess 4 in the table, said recess forming a space in which the operator may stand when working said lever. On the inner portion of the crank shaft 23 is fixedly mounted a spur gear 29 which is in operative engagement with a similar gear 30 fixed on the drive shaft 16 whereby the movement of the operating lever or handle 25 is imparted to the drive shaft and the latter and the part-s driven thereby thus operated by hand power.

In order to hold the block or bolt of wood in position to be engaged by the knife 9 for cutting the shingles therefrom, I provide a suitable bolt or block holding and feeding mechanism comprising a feed screw 31 which has a threaded engagement with a supporting post 32 secured to the table 1 as shown. The feed screw 31 also has a sliding engagement with an apertured guide plate 33 secured to the outer edge of the table. On the outer end of the feed screw 31 is fixedly mounted a hand wheel 34 and on the screw adjacent to the outer end thereof is arranged a stop collar 35. To the outer end of the shaft 31 adjacent to the inner side of the hand wheel 34 is loosely connected a feed board supporting yoke 36, said yoke having diverging arms 37 and 38. The end of the arm 38 is firmly secured to one end of a feed board 39, while the end of the arm 37 is loosely connected to the opposite end of the board 39 by a headed pin or stud 40 whereby this end of the board is permitted to have a limited independent movement.

The inner end of the feed screw 31 is reduced and said reduced end has a loose engagement with the center of the feed board as shown. On the inner end of the feed screw adjacent to the side of the board 39 is arranged a laterally projecting shifting pin 41 which is adapted to be engaged w1th a segmental cam 42 secured to the adjacent side of the feed board on one side of the screw as shown. By thus arranging the pin 41 and cam 42, said pin will be brought into engagement with the cam at each revolution of the shaft and when thus engaged with the cam will swing the loose end of the board inwardly against the pressure of a spring 43 secured to the opposite end of the board and engaged with the arm 38 of the yoke. "When the pin 41 has been brought around out of engagement with the cam 42 the spring 43 will swing the loose end of the board 39 back against the end of the arm 37. By arranging the feeding and shifting mechanism of the board 39 as herein shown and described it will be seen that as the board is fed forwardly by the feed screw the board and the block or bolt being fed thereby will be shifted back and forth at one end after each shingle is out there from, thus causing the knife to alternately cut the shingles thick end first and then thin end first from the block thus preventing any waste of wood.

The block or bolt of wood is secured to the feed board 39 by means of block gripping dogs 44 which are pivotally mounted in notches formed in the opposite ends of r the board and are adapted to be engaged by stiff springs 45 secured to the outer sides of the board and engaged with the dogs as shown. The dogs are preferably provided with suitable handles 46 whereby the same may be actuated to engage and release the blocks or bolts of wood secured thereby to the feed board.

From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention claimed.

Having thus described my invention, what I claim is: c

1. A feeding mechanism for shingle making machines comprising a feed screw supporting structure, a feed screw having a threaded engagement with said structure, a feed board supporting yoke loosely con nected to said screw and having diverging arms, a feed board firmly secured at one end to one of the arms and having a loose connection at its other end with the opposite arm, and means operable at each revolution of the feed screw for shifting the loose end of the board. 7

2. A feeding mechanism for shingle making machines comprising a feed screwsupporting structure, a feed screw having a threaded engagement with said structure, a

nected to said screw and having diverging arms, a feed board firmly secured at one end to one of the arms and having a loose con-. nection at its other end with the opposite arm, means operable at each revolution of the feed screw for shifting the loose end of the board, and means for returning the free end of the board after it has been shifted.

3. A feeding mechanism comprising a feed screw supporting block secured to the table, a feed screw having a threaded engagement with said block, a hand wheel fixedly mounted on the outer end of said screw, a feed board supporting yoke loosely connected to said screw, said yoke having diverging arms, a feed board firmly secured at one end to one of said arms and having a loose connection at its other end to the opposite arm, a segmental cam arranged on one side of said board adjacent to the inner end of the feed screw, a shifting pin arranged in the end of said shaft and adapted to be engaged with said cam at each revolution of the feed screw whereby the loose end of the board is shifted, a spring to swing the free end of the board back after being shifted by said pin and cam.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
