SPECIFICATION forming part of Letters Patent No. 652,772, dafd T 111e' 3, 190@ A Application filed February 4, 1898. Serial No. 669,070. (No model.)

To au whom it. may concern:

Be it known that we, WILLIAM HINDLEY,

of Hoboken, in the county of Hudson and' State of New Jersey, and JOSEPH WM. HARD- ING, of New York, (Brooklym) in the county of Kings and State of New York, have invented certain new and useful Improvements in Wood-Sawing Machines, of which the following is a full, clear, and exact description. This invention relates to improvements 'in wood-sawing machines, but more particularly to machines for sawing kindling-wood.

The primaryy object of the invention is to` provide a simple and efficient machine adapted to receive long bundles of wood bound at stated intervals, which will carry the bundles forward, and which will hold and cut the bun-v forming a part of this specification, wherein similar figures of reference designate similar parts, Figure 1 is a side elevation of one form of the machine embodying our invention. Fig. 2 is a sectional plan View, partly broken away, taken on the line II II of Fig. 1. Fig. 3 is a vertical transverse section, partly broken away, taken on the line IIIIII of Fig. 2. Fig. 4 is a fragmentary longitudinal vertical section taken on the line IV IV of Fig. 3, and Fig. 5 is a fragmentary detail view illustrating means for imparting a vertical movement to the saws.

The frame may be of any desired form and may consist of lsections 10 and 10?, suitably bolted and secured together, in the former of which are journaled the transverse'shafts 11 and 12. On each of these transverse shafts is secured a drum 13, provided at intervals with sprocket-teeth which engage the links of the endless chains or carriers 14, though insteadof thel drums a series of sprocket- 4wheels may be employed corresponding in number to the number of endless chainsror carriers with which they engage. On the .chains14 and arranged at stated intervals are buckets or jaws 15, which maybe secured to or formed as a part of one of theJ connectwith the gear 17 is a ratchet-wheel 19, normally engaged by a spring-pressed pawl 20, pivoted to the arm 21, the latter having one end journaled loosely on the shaft or stud 1S and its other end provided with a stud or pin 21a, on which maybe arranged a roller normally in engagement with the grooved cam 22. This cam 22 is secured to the .shaft 23, on which may be arranged a drive-pulley 24, so that when the latter is rotated thecam 22 will rock the arm 2l on its pivotand through the pawl-,and-ratchet andjgear mechanism already described will impart anintermittent movement to the drums 13 and the endless chains or carriers 14, so as to carry the bundles of lwood forward the distance between any two series of jaws or buckets 15 at each revolution of said cam. Y

The bundles of wood 15a as they aredropped into the buckets 15 assume the position shown to the right in Fig. 1, and as thechains 14 and buckets 15 are advanced the Ywood will contact lwith a suitable engaging device. As

- shown, this device comprises .a series of rollers 25, which are arranged to rotate'with the transverse shaft 26 (shown in- Figs.j1' and 2) in order that the bundles of wood when'engaged by the rollers maybe forced or rocked so as to assume the position shown in full lines in Fig. 4. For the purpose of holding the bundles while being cut or separated we may provide a movable head or clamping device IOC 27, arranged to slide in the sections l0 of' the frame, and on the under side of said head, between the sections of the frame are arranged a series ot clamping-jaws or buckets 28, corresponding in form to the buckets- These jaws 28 have their con-y caved portions opposed to the concaved porl tions of the buckets 15, so as to snbstantially surround the bundle when the latter is or jaws 15.

tions 10a of the frame and have their upper. ends pivoted to rock-levers 32, the latter having one end thereof connected to the links 33, pivoted to the sections of the frame, and

their other ends connected to verticallymovable connecting rods 34.

arms or levers 35, secured `to the transverse shaft 36, one of said arms being .extended so j as ,to form a bell-crank lever and provided at its upper end with a roller 36, which nor-A mally engages a cam-groove in the cam 37, which is .secured toa stud or shaft 38. 0n

the shaft 38 `is Varranged a gear 39, which meshes with an idler 40 on the shaft 12,1V which in turn meshes with an idler 4l, the i latter being in mesh with the gear 42, se cured to the drive-shaft 23, so that v.when the latter 'is rotated the trai-n of gearing will impart a rotary movement to the shaft 38. This shaft 38 is properly timed with respect. to the intermittentmovementof the sprocketrotated said shaft,' through the .cam 37, roller 36, arms `35, lcon,` necting-,rods 34, and its connections, will impart a vertical movement to the .clamping- A series of grate-bars 43 are arranged below ,the head 27, forming a stationary bed over which the chains 14 are adaptedl to pass in order to forma support for the. chains carrying the buckets or yjaws when the clamping-head-27 is forced downward to 1 hold the bundle of wood. These grate-bars may be secured to -T-shaped 4cross-' bars, aSi

drums 13, and when head 27.

44, secured to the sections 10 of the frame,

though instead of the grate-bars any suitable bed may be provided.

These saws are separated by suitable collars back and forth in the sections 10 of the frame, and the shaft 46 is connected to the links 50, the outer or forward ends of which These arms are secured to the transverse shaft 51u, one of. which arms is connected by a rod 52 to a rockare pivoted to the arms 5l.

These connecting-rods have their lowerends pivot-ed to arm 53, loosely arranged upon the transverse shaft 36.. This arm 53 may have a suitable roller which engages a cam-groove in the cam 54, the latter being secured to the shaft 38, so as to rotate with the cam 37. By this means the saws are moved inwardly toward the clamping-head 27, so as to divide the long bundle into independent smaller bundles or packages 151.

The saws 45 may be rotated in any desired manner. As shown, the shaft 46 has a pulley 55 at oneend thereof, around which passes a belt 56, which is rotated by the pulley 57, the latter being suspended by movable links 58, arranged on the shaft 59. The links 58 are connected to the shaft 46 by the connecting-rod 60, so that the shafts of the pulleys 57 and 55 will remain .a fixed dist-ance apart. To the shaft Aot the pulley 57 is secured a pulley 61, which is rotated yby a belt `62 which passes around ,the pulley 63, arranged .0n .the shaft 59, the latter shaft being suitably suspcnded and rotated by means of Hthe drivepulley 64. The arrangement `o t' the links 58 permits the sha-ft 46 `to be constantly rotated while being moved lengthwise of the machine.

vThe operation of the invention will be readily understood from the foregoing description when taken in connection with thc ,accompanyin g drawings.

The bundles .of wood being deposited in ,the buckets or `jaws 15 in .any suitable manner and the pulley 4,2 rotated, it will be seen that the cam 22 will rock the arm 2l on its pivot, and through the pawl 20 ratchet-wheel 19, gear 17, and pinion 1=6 .anintermittent movement will be imparted tothe shaft 12,7 drums, and endless chains 14, thus advancing the bundles in the buckets or jaws. As the chains .advance `the bundles contact with ,the rollers 25 on the transvers shaft 26 s0 vas to be forced to the position shown in Fig. 4. This intermittent movement continues until one series of buckets are in alinement with the clamping -head 27 yThe head is now moved downward 'by the rods 30, levers 32, connectingrods 34, arms 35, and cam 37, which latter is rotated by the train of gearing from the shaft 23, as hereinbefore described. Vhile ,the bundle is clamped between the jaws 15 of the chain, which is supl ported by the 4{.*rate-bars of the bed and .the The saws 45 may be 0f any desired number I and are varran ged on the transverse ,shaft 46.

jaws 28 of the clamping-head 27, the saws 45, which are rotated by the driving lmechanism heretofore referred to, are moved inwardly toward the head to the position shown in the drawings by the links 50, arms 51, connecting-rod 52, rock-arm 53, and cam 54, thus separating the bundle of Wood into a number of smaller and independent packages. The

:clamping-head 27 is now raised by the mechanism already described. The saws 45,

ICO

ously with the outward movement of the arms 45 the drums 13 and chains 14 are given an intermittent movement, so as to place the next bundle in position for the clamping-head to engage and rigidly hold the same for the next inward movement of the saws 45. The operation is repeated, and the divided bundles are carried outward by the carriers or chains, and, as the buckets rotate around the drum on the shaft 1l, may be removed or they will be dropped on the floor, as shown in Fig. 1, or into a suitable receptacle provided therefor, as desired.

We thus provide an efficient machine which will carry the long bound bundles of wood forward, hold and cut the same between the bindings ready for the market, and after being cut the smaller bundles will be carried outwardly, so as to be readily removed or dropped into a suitable receptacle provided therefor.

While we have described mechanism for intermittently moving the carriers or chains as a part of the machine, we may arrange said or similar mechanisln on a suitable bundlingmachine, such as described in our pending application, Serial No. 658,256, iiled November 12, 1897. When used in this manner, the chains or carriers are arranged so that the long bundles of wood when bound will drop from the binding mechanism directly into the buckets or jaws 15.

In some instances it may be found desirable to move the saws vertically instead of horizontally, as shown in Figs. 1 to 3, inclusive. In such case the saws may be suspended from an oscillatory lever or arranged as shown in Fig. 5. Here the shaft Li6 is journaled in the cross-heads 65, which are vertically movable in the sections 10 of the frame and are connected to the links 66, only one section of the frame and the connecting parts being shown. The links 66 are connected at one end to levers 67, one of which connects to a rod 68, the latter being operated in a similar manner to the rod 52, (shown in the other figures,) so that as the levers 67 are rocked on their pivots the saws,throu gh thelinks 66,will be given a vertical movement. When thus arranged, the saws maybe carried away from the path of movement of the bundles after the same have been cut and before the clamping head or device 27 is released.

It will be readily seen that other clamping means than the head may be employed, that any desired form or construction of saw or saws may be used, and that some of the parts may be dispensed with or others substituted therefor without departing from the spirit of our invention.

Having thus described our invention, we claim as new and desire to secure by Letters Patenta second series of vertically-movable jaws also shaped to fit the stock and adapted to close over the same when the traveling jaws are at rest, and a series of rotatable saws movable between the jaws and in the path of the stock, substantially as described.

2. A wood-sawing machine, comprising a series of intermittingly-movable chains, each having buckets or jaws at stated intervals thereon, the said jaws being shaped to iit the stock and arranged with the jaws of one series parallel with those of adjacent series of chains, vertically movable and similarlyshaped jaws adapted to close over the stock opposite one of the traveling series of jaws when the latter are at rest, and a gang of rotary saws arranged in the path of the stock and between the series of jaws, substantially as described.

3. A wood-sawing machine, comprising a series of intermittingly-movable chains,buck ets or jaws arranged at intervals on the chains, the jaws of one chain parallel with those of adjacent chains, the said jaws being shaped to fit the stock, similarly-shaped verticallymovable jaws adapted to close over the stock in the traveling jaws when the latter are at rest, and a gang of rotary saws arranged in the path of the stock and between the jaws, the said saws being movable backward and forward in relation to the stock, substantially as described.

4. In a machine of the kind described, the combination with the series of traveling jaws shaped to tit the stock when the latter is in IOO a certain position and arranged in parallel relation, of automatic means for tilting the stock into its fitting position in the jaws, a second series of vertically movable jaws adapted to fit over the stock and bind it in the traveling jaws, and saws arranged in the path of the stock, substantially as described.

5. The combination with the intermittinglymoving parallel series of jaws shaped to fit the stock when the latter is in a certain position, of means as the series of rollers arranged in the path of the stock to tilt it into its best position in the jaws, a second series of vertically-movable jaws adapted to close over the stock and bind it to the traveling jaws, and a gang of saws arranged to sever the stock between the jaws, substantially as described.
