SPECIFICATION'formng part of Letters Patent No. 585,741,6.ated July 6, 1897 Application filed August 18, 1896. Serial No. 603,144. (No model.)

T @ZZ whom t may concern:

Be it known that I, PATRICK CONWAY, a citizen of the United States, residing at New Whatcom, in the county of Whatcom and State of W'ashingtomhave invented a new and useful Clapboard-Machine, of which the following is a specification.

This invention relates to clapboardmachines, and has for its object to provide a Io simple, compact, and efficient machine for sawing clapboards in which advantage is taken of both movements of the carriage for operating on the bolts. clapboard is sawed in the forward movement I5 of the carriage and an additional one in the return movement thereof.

The invention also contemplates novel means for holding and releasing the bolts and for tilting the same and regulating the bevel zo and thickness of the clapboards.

Other objects and advantages of the invention will appear in the course of the subjoined description. l

The invention consists in a clapboard-sawing machine embodying novel features and details of construction and arrangement of parts, as hereinafter fully described,illustrat ed in the drawings, and incorporated in the claims.

In the accompanying drawings, Figure 1 is a plan view of a clapboard-sawing machine constructed in accordance with the present invention. Fig. 2 is a cross-section through the same. Fig. 3 is a detail section showing 3 5 the manner of mounting one of the tilting tables. Fig. 4 is a perspective view of one of the carriage-sections. Fig. 5 is a longitudinal section through one of the carriage-sections, showing the manner of holding a bolt 4o therein. Fig. 'is an enlarged detail crosssection taken through one end of the machine,

showing one of the tilting tables.

Similar numerals of reference designate corresponding parts in the several iigures of the drawings.

Referring to the drawings, 1 designates the framework of the machine,which, for the purpose of carrying out the present invention, comprises elevated side longitudinal bars 2 5o and an intermediate or middle bar 3.

In other Words, a

4 designates the saw mandrel or shaft, which is vertical and carries a circular saw 5 at its upper end, said saw working slightly below the plane of the top of the frame 1.

Extending longitudinally of the machineframe are metal guides or grooved tracks 6. These tracks are preferably four in number and are arranged in parallel pairs, the inner adjacent edges thereof being` grooved, as shown at 7, to receive slidingly the oppositely- 6o projecting guide-flanges 8 of the carriage-sections `9. Each carriage-section 9 is substantially rectangular in form, corresponding to the length and width of the clapboard to be sawed. It is also formed with an open center and is provided at one end with teeth 10 for engaging one end of the bolt and at the opposite end with a sliding and spring-actuated dog 11 for engaging and releasing the opposite end of the same bolt. At this end of the 7o carriagesection parallel vertical flanges 12 are provided, the same being provided with registering openings 13, through which slide `the spaced bars or stems 14 of the dog 11.

Between the iianges 12 and surrounding 75 the bars or stems 14 are coiled springs 15,which engage therewith in such manner as to normally thrust the` dog inward for forcing its teeth into engagement with the bolt. The dog is further provided with a central arm 16, 8o which bears in an opening in the inner flange 12 and is pivotally connected at its rear end with a dog-operating lever 17, fulcrumed at one end on its respective carriage-section. In the reciprocation of the carriage-section the free end of this operating-lever strikes against a stationary trip, shown in the form of a vertical pin projecting upward from the central bar of the frame, so as to lie in the path of said lever. 9o

18 designates a pair of tilting tables arranged one at each end of the frame 1. Each of said tables is provided with central end journals 19, which enter suitable bearings in the frame, and one of the journals passes through one of the end bars of the frame and is provided outside thereof with a spring-arm 20, by means of which the table maybe tilted, said spring-arm engaging with the teeth or notches of a segmental rack 21, secured to rco the outer face of the end bar concentric with the journal therein. By moving the arm 2O to one side or the other the table may be tilted to any desired angle and held fixed. The tables 18 are arranged at the initial point of stroke of their respective carriagesections, and the trippins (indicated at 22) are so located that just as each carriage-section passes over its respective table at the end of its return movement the operating-lever 17 is vibrated or held in such manner as to move the dog 11 out of engagement with the bolt,where upon said bolt falls upon the table, thus giving to its bottom surface an inclination corresponding to that of the tilting table. The saw 5 is arranged in a horizontal plane and therefore makes a horizontal cut through the bolt, thus providing the clapboard with one thick and one thin edge in the usual manner.

Arranged at one end of the machine is a pulley or wheel23, having parallel cranks 24E attached to its shaft, and from these cranks connecting-rods 25 extend to the adjacent ends 'of the carriage-sections, whereby the latter are reciprocated simultaneously in the same direction.

From the foregoing description it will be seen that as the dou ble carriage moves in one direction a clapboard is sawed from one of the bolts and as it moves in the opposite direction another clapboard is sawed from the other bolt. At the same time the bolt-holding dogs are automatically released and again forced into engagement with the bolts, the latter adjusting themselves by gravity for giving the proper bevel to the clapboards.

It will be understood that the several parts of the machine are susceptible of changes in the form, proportion, and minor details of construction, which may accordingly be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

Having thus described the invention, what is claimed as new is- 1. In a clapboard-sawing machine, a reciprocating bolt-carrier consisting of an open rectangular frame having inwardly-projecting teeth on one of its end walls, and a iiange extending from side to side in advance of the other end wall and parallel therewith, a toothed dog arranged in front of the flange and having a stem projecting rearwardly through the flange and the end wall of the carrier, a spring on the stem abutting against the end wall and tending normally to force the dog forward, an arm extending rearwardly from the dog through the flange and bent upwardly, a lever pivoted at one end to one side of the carrier and connected intermediate its ends with the said arm, and a fixed stop on the machineframe to engage the free end of the lever and cause it to retract the dog, substantially as described.

2. In a clapboard-sawin g machine, a tilting table provided with central end journals one of which is supported in the end bar of the machinesframe and projects outwardly be yond it, and the other in a suitable bearing within the frame, a segmental rack 2l secured to the outer face of the said end bar concentric with the projecting journal, and a spring-arm connected to the projecting journal to rock the table and adapted to engage the teeth of the rack to lock the table in its adjusted position, combined with a reciprocating bolt-carrier, and means to release the bolt from the carrier to permit it to drop onto the table, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

PATRICK CON WAY.
