BENJAMIN F. GIBBS, OF KANKAKEE, ILLINOIS.

MACHINE FOR WORKING WOOD OR METAL.

SPECIFICATION forming part of Letters Patent No. 582,195, dated May 11, 1897. Application filed March 23, 1896. Serial No. 584,874. (No model.)

To all whom it may concern.-

Be it knownthat I, BENJAMIN F. GiBBs, a citizen of the United States, residing at Kankakee, in the county of Kankakee and State of Illinois, have invented certain new and useful Improvements in Machines for WVoi-king Wood or Metal, of which the following is a specification.

My invention relates to certain improvements in machines for working wood or metal; and to this end it consists in constructing a machine which shall be practical, complete, and positive in its operation.

The invention consists, broadly, in providing a suitable framework, an endless carrier continuously moving in one direction, a toolcarriage which shall at certain predetermined intervals be carried along with said endless carrier and perform the operations desired upon the blocks of wood or metal which are carried by said endless carrier, and to certain other minor details of construction which will hereinafter be fully described. Upon the completion of such an operation the tool-carriage shall automatically return to its normal position to be in readiness for a subsequent operation. I

The invention is fully described in this specification and shown in the accompanying drawings, in Which Figure 1 is a front elevation of a machine, partly broken away. Fig. 2 is a plan view of one of the tool-carriages, one of the links of the endless carrier, and a portion of the guidin g-rails or supports upon which the movable portions are mounted. Fig. 3 is a side view of a portion of one of the links of the chain. Fig. 4 is a front view of a portion of the guidin g-rails, partly broken away,and showing one of the tool-carriages. Fig. 5 is a view, partly in side elevation and partly in vertical section, the plane of section being taken in line 5 5 of Fig. 2. Fig. 6 is a vertical cross-section through one of the tool-carriages and framework of the machine, the section being taken in line 6 6 of Fig. 2. Fig. 7 is a detail horizontal section of a clutch used in connection with the device, the section being taken in line 7 7 of Fig. 6. Fig. Sis a detail side elevation of said clutch, looking in the direction of the arrow 8 in Fig. 6. Fig. 9 is avertical cross-section through the carriage in line 9 9 of Fig. 6. Fig. 10 is a detail cross-section of one of the adjusting devices for-the tool, the section being taken in line 10 10 of Fig. 6; and Fig. 11 is aview of the carriage and guidingrails, partly in end elevation and partly in cross-section, the section being through the line 11 11 of Fig. 2;

Referring to the drawings, and especially to Fig. l, which shows a front View of a complete machine, but considerably broken away, A represents the framework, constructed of suitable members to form a good and substantial frame, the exact construction of whichis not particular to my invention, the essential features being to form a substantial framework of simple design. The upper portion is formed with a horizontal table or plate A, (see Fig. 6,) upon which are secured the supporting guiding-rails adapted to carry the endless conveyer and the tool-carriages, respectively.

The framework is provided at each end with brackets a a, suitably braced and strengthened, upon which are journaled two wheels W \V, adapted to propel the endless carrier and having sockets to in their peripheries adapted to receive the connecting-pins of the endless carrier, hereinafter described. The wheels WV W, as shown, are constructed of radial arms extending to their outer peripheries, where the sockets w are formed, the ends of the arms being connected by flat tangential members 10, adapted to receive the links of the endless carriers as they are carried around with the wheels.

The wheel W is shown as the driver, and upon its shaft is secured a worm-gear 10 in mesh with a worm 20 journaled in suitable bearings upon the bracket a, and upon its shaft is a pulley adapted to be connected to any suitable source of motive power to propel the machine. This forms a very simple means for propelling the machine, but I do not, however, desire to limit myself to this particular means of gearing, as various ways of gearing the machine may be employed.

The endless carrier B is best seen in Figs. 2, 3, 4, and 6, and consists, preferably, of links I) b, connected by suitable pins, sleeves I) being preferably placed upon the pins between the links I) to properly space them apart. The links I) of the endless carrier are preferably constructed of solid blocks, and upon these links is secured the stock which is to be shaped by the machine. The sockets w of the propelling-wheels W \V receive the sleeves b and carry the endless carrier around with them, thus propelling the same continuously in one direction at a comparatively slow yet steady and even motion.

Above the frame of the machine is hung a shaft S, (see Fig. 1,) which is preferably driven at a sufficient speed to impart the necessary speed to the cutting-tools to insure their perfect operation upon the stock, and upon this shaft are secured drums S of proper length,

the object and purpose of which will hereinafter he described.

Upon the plate A is rigidly secured a guiding rail or track A adapted to support and guide the endless carrier B. Looking at Figs. 4 and 6 it will be seen that this guiding rail or track is channel-shaped, having the overhanging edges a which assist in keeping the endless carrier in perfect alinement and prevent the same from accidentally being raised out of its seat in the channel portion of the track. \Vithin the channel portion are rails (i of, having smooth bearing-surfaces upon which the endless carrier slides. The links Z) of the carrier are provided with grooves on their edges adapted to embrace the overhanging edges of the channel guiding-rail and the lower faces of said links are smooth and slide upon the rails (i The rails a a are made adjustable, so as to take up the wear upon the same, said adjustment being shown as consisting of screws extending through the supporting-rail A and bearing upon the rails a a and by tightening or loosening these screws the rails may be adjusted as desired.

The links I) of the endless carrier are provided with clamps adapted to hold the stock thereto, the exact construction of which is immaterial to my present invention; but the one which I have shown I have found to be very practical and effective in its operation.

As shown in Figs. 2, 4, and 6, this clamp consists of a link pivoted to a laterally-extending lug upon the link I). To the upper end of the link is pivoted a bell-crank lever b I), the arm b of which extends upward and away from the pivot, and the arm 5 is pivoted to a horizontal member D which extends across the face of the stock and when in a locked position impinges upon the upper face thereof and securely clamps it to the link. The horizontal member 11 has two laterallyextending lugs pivoted to standards formed upon the link near its outer edges; and it is obvious that the horizontal member may be swung away from thestock when it is desired to disengage the same.

The endless carrier travels in the direction indicated by the arrows in the various figures, and the stock to be operated upon is secured in place upon the links I) at the right-hand end of the machine in Fig. 1. It will be seen that at this end of the machine the clamps I are in an unlocked positionthat is to say, the horizontal members 11 are swung away from the links-so that the stock can easily be secured thereon by inserting it in place and throwing the bell-crank lever in the direction indicated by the arrow thereon in Fig. 1 until the pivot of the horizontal member has passed by the line through the pivots of the link b when the stock will be clamped firmly in place. At the opposite end of the machine is placed a tripping device Z), having a pin extending into the path of the arm b of the bell-crank lever. hen the arm 0 of the bell-crank lever strikes the projecting pin upon the tripping device I), it is swung upon its pivot, thus swinging the link 1) upon its lower pivot, and at the same time the arm Z2 of the bell-crank lever swings the horizontal member b away from the stock. hen this link of the endless chain passes over the wheel V, the finished piece of stock falls into a suitable receptacle and the link is carried around to the other end of the machine for subsequent use.

Upon the plate A are secured the bearingways A extending along the side of the guiding-rail A and parallel therewith and adapted to support and guide the tool-carriages. These tool-carriages are located along the bearing-ways at suitable distances apart and are provided with rotating cutters or other tools adapted to shape the stock. There are as many of these tool-carriages as there are operations required upon the stock; but as all of these tool-carriers are of similar construction the description of one of them will pertain to. them all.

The upper faces of the bearing-ways A are formed so as to present smooth bearing-surfaces, and upon them rest bed-plates G of the tool-carriages. Each of the bed-plates is guided along the bearing-ways in any suitable manner, the one shown being by means of ribs 0, projecting downward between the ways (see Fig. 6) and bearing down upon the inner edges of the same, and a plate 0, se cured to the under side of the ribs and bearing upon the under sides of the overhanging edges a of the ways A. The ribs 0 slide along the inner faces of the overhanging edges in the travel of the tool-carriage along the ways and guide the same thereon.

The bed-plate G is provided with an opening 0 near its rear end, (see Fig. 6,) through which projects a gudgeon d, formed upon a cross-feed bed-plate D, which rests upon the bed-plate O. The cross-feed bed-plate D moves longitudinally with the bed-plate C,and it may evidently be swung upon the bed-plate 0, using the gudgeon d as a pivot, when it is desired to make certain operations upon the stock at different angles thereto to that of a right angle. As will be seen from the various figures, the cutting-tool (which is shown as a circular saw) is at right angles to the endless carrier, but by swinging the bed-plate upon which this cutting-tool is mounted, using the IIO gudgeon as a center, it may be made to assume any angle toward the carrier and perform such operations to the stock as readily as if it were at right angles thereto.

Looking at Figs. 2, 3, and 6 it will be seen that a lug b is provided upon the inner side of the link bthat is, the side contiguous to the tool-carriageand this lug is adapted, at certain predetermined moments, to engage the various tool-carriages with which the machine is provided and carry them along with it successively as it passes along, each link being obviously provided with a similar lug.

As seen in the last-named figures, the bedplate 0 extends along the bearing-ways for a short distance, and near its end a bracket 0 is adj ustably secured thereto. I have shown bolts 0 passing through the bracket and through suitable slots in the bed-plate C, by which the bracket maybe adjusted along the bed-plate to its propel-position. The bracket 0 is formed with two ears 0, in which is seated a reciprocating shaft S one end of which projects beyond the side of the carriage and lies in the path of the lugs 12 upon the endless carrier B. Upon the reciprocating shaft S are secured two sleeves c c, the sleeve a being adapted to limit the movement of said shaft toward the endless carrier, and between the sleeve and ear 0 is a coiled spring S adapted to throw the end of the shaft into the path of the lug 19 The reciprocating shaft S is connected with a lever 0 fast upon a rock-shaft S journaled in an ear 0 extending from the bracket C, and upon the lower end of this rock-shaft is secured a second lever 0 adapted to strike a stop 0 adjustably secured to the outer face of the bearing-way. As shown, this stop is composed of a fiat plate having a slot therein extending longitudinally of the bearing-way A a bolt securing it to the latter at any place along the slot, and a projecting lug extending into the path of the lever 0 When the lug b strikes the shaft S it is evident that it must carry the tool-carriage with it at the same speed as the endless carrier until the lever O strikes the stop 0 the further movement toward said stop causing said lever to be swung in the direction indicated by the arrow thereon in Fig. 2, thus rotating the shaft S with it, swinging the lever C and drawing the shaft S out of engagement with the lug b allowing the endless carrier to continue its movement and the toolcarriage to return to its normal position by l I i a suitable device, the exact construction of which is not necessarily essential, but the one which I have shown being a very simple means for returning the carriage to its normal position. By the use of this mechanism for engagement with the endless carrier I am enabled to place any number of tool-carriages along the machine, each one being adapted to be operated independently of the others.

In Fig. 9 it'will be seen that the bed-plate C of the tool-carriage is provided with ears,

to which is pivoted a pitman P, connected with the free end of a bell-crank lever P P, secured upon a shaft S journaled upon the frame of the machine. The free end of the arm P of the bell-crank lever is provided with a suitable weight of sufficient power to draw the carriage to its normal position. The working movement of the tool-carriage is in the direction indicated by the arrow thereon in Fig. 9, and when such movement takes place it draws the pitman P with it, swinging the bell-crank lever upon its shaft, raising the weight "W until the shaft S has been released from the lug h", when the force of the weight W will carry the tool-carriage back until it strikes a stop 0 secured upon the inner sides of the bearing-ways. This stop is made adj ustable for the purpose of limiting the backward movement of the tool-carriage for certain reasons hereinafter described.

It is obvious that by moving the reciprocating shaft S toward the cutting-tool the latter will be caused to cut upon the stock nearer the middle portion thereof, and that by varying the position of the lug 19 upon the link the cutting-tool may be made to cut or operate upon the stock at any point upon the same.

Upon the side of the bearing-rail A is secured a stationary rack E, which may, if desired, extend along the entire side of the machine, or each tool-carriage may have a separate rack. A shaft S is journaled in the gudgeon d of the cross-feed bed-plate D and carries upon its lower end a clutch E, adapted at certain intervals to connect the shaft S with a pinion E loosely mounted on said shaft and in mesh with the stationary rack E. This pinion E is supported in any suitable manner, the one shown being a bracket 6-, secured to the bed-plate C and having the portion 6 seated in an annular recess 6 in the pinion E The lower face of the pinion E is provided with jaws 6 adapted for engagement with corresponding jaws 6 upon the clutch E, (see Figs. 7 and 8,) and this clutch is provided with a recess in which are seated two collars e e, the object of which will be hereinafter described.

Looking at Fig. 4 a bell-crank lever F F will be seen pivoted to the outer face of the bearing-way A the arm F thereof normally lying in the path of the lugs 1)" upon the links I) of the endless carrier. The arm F rests in the forked end of an arm F pivoted to adepending lug 0 upon the bed-plate C, said arm being a portion of a device for throwing the clutch E into engagement with the pinion E". f is a link connected with the collar 6 and extending upward, where it is connected with an arm F (see Figs. 2, 5, 6, and 11,) extending around the gudgeon cl in an approximately horizontal plane, then in a longitudinal direction a short distance, where it is pivoted upon a lug c in a line concentric with th'epivot of the arm F At this point the levers F F are connected with a crossbar F which may be made integral there with or secured thereto in any suitable manner, the object being to give the same amount of oscillation to the arm F which the arm F received upon the opposite side of the machine.

Each lug 12 upon the link I) of the endless carrier, as it passes along, comes in contact with the shaft S and moves the carriage along with it, as has been heretofore described, but just before striking the shaft S the lug encounters the arm F of the bell-crank lever and while passing over it rotates it slightly in the direction indicated by the arrow thereon in Figs. 4 and 5. It will be noticed in the drawings that the position of the link I) is at a point where the lug b has come into engagement with the shaft S Hence the lever F has already been rotated in the direction of the arrow thereon in Fig. 4. This causes a corresponding rotation of the arm F of the bell-crank lever, thus raising the free end of the arm F of the clutch-operating mechanism, swinging the cross-bar and arm F in the direction indicated by the arrows thereon in the respective figures, and thus lifting the clutch into engagement with the pinion E through the link f.

The collar 6 (see Figs. 5, 6, and 11) is connected with the free ends of arms G, fast upon a rock-shaft S journaled in suitable brackets cl, supported from the cross-feed bed-plate D. To the outer end of the shaft S is secured a lever G, extending upward to the top of the bed-plate D, where it is provided with a pin g, (see Fig. 2,) lying in the path of a lug g upon a plate G adjustably secured upon the cross-feed block H,l1ereinafter described. The block H is provided with a rib 9 one end of which has a pin g extending laterally therefrom and into a slot in the plate G The plate G can evidently be moved along the rib g to any desired point, and a bolt 9 is provided whereby the plate can be secured in place, the purpose of this adjustment being to allow the proper amount of movement of the tool-carriage toward the stock, so that if it is desired the lug g may be adjusted (as it is in the drawings) so that the cutting'tool passes across the entire width of the stock. It may, however, be adjusted so that the cuttingtool will only make a slight kerf or other operation which may be desired upon this stock.

As has heretofore been described and explained and shown in the drawings, the clutch is in engagement with the pinion E Therefore the lever G will be in a position adapted to be operated upon by the lug g.

The cross-feed bed-plate D is formed with dovetailed bearing-ways D, in which slides the cross-feed block H, which carries the cutting-tool. As seen in Figs. 5, 6, and 10, these bearing-ways comprise the bearing-faces d upon which the cross-feed block slides, and overhanging faces d adapted to guide corresponding faces upon the block and prevent it from any accidental upward displacement. I have shown a strip (1 in the ways adapted to take up any wear on the block, this strip being provided with suitable screws for adjusting it to take up such wear. Below the bearing-faces d the bed-plate is provided with a longitudinal groove in which is a downwardlyprojecting flange it upon the block II, and upon the face of this flange is secured a rack H, which is in mesh with a pinion E fast upon the upper end of the shaft 8, which passes through the gudgeon d upon the bed-plate D.

The pinion E is at certain predetermined times caused to rotate, thus giving to the cross-feed block ll longitudinal movement, said movement causing the cutting-tool to operate upon the stock, as will be hereinafter described. To return the block H to its normal position-namely, the one illustrated in the drawings-I have provided a device similar to the one used in returnin the complete tool-carriage to its normal position, heretofore described. The lever is shown at D D pivoted upon a bracket (Z secured to the rear end of thecross-feed bed-plate, the upper end of said lever being connected with a pitman D which is in turn connected with ears it upon the block H. The lower end of the arm D is provided with a suitable weight, which, when swung upward by the forward movement of the block H, is in a position to draw the same back to its normal position when it is released from such forward movement through its gravity. The form and construction of these devices for returning the toolcarriage are simple and effective, but it is not essential that they be of the exact construction shown and described, as straps attached to the tool-carriage and. block, respectively, and passing over suitable supporting-rollers would serve the purpose just as well.

The block H is provided at one end with an upwardly-extending neck from which projects a horizontal clamping-block H in which is secured a spindle I of a face-plate I. The clamping-block I1 is slit, as seen in Figs. 5 and 6, and provided with set-screws in its upper edges, by which the spindle I may be securely clamped therein. The face-plate I is provided with a dovetailed groove i, in which is seated a correspondingblock J ,which is vertically adjustable therein by means of a screw j, threaded in said block and journaled in an overhanging lug 2', formed upon the upper end of the face-plate I, sleeves j j being provided upon the screw on each side of said overhanging lug to prevent any longitudinal movement thereof. The upper end of the screw is preferably squared, so that a wrench may be applied thereto and the screw rotated, thereby raising or lowering the block J for the purpose of making a shallow or deep cut in the stock. The block J is provided with a journal-bearing J, in which the shaft S of the cutting-tool is journaled. The tool is shown at T and secured to one end of the shaft S the other end of the shaft being provided with a suitable pulley p, geared to the drum S by a belt 19, as seen in Fig. 1.

It is evident that the cutting-tool T may be turned in almost every direction with reference to the stock and that various shapes and operations may be made upon the stock. As shown in the drawings, the tool is placed in a vertical plane, but by loosening the setscrews in the clamping-block H the spindle I may be rotated and adjusted in any suitable position therein, the set-screws again tightened,th us holding the cutting-tool at the angle desired. The entire cross-feed bedplate may be swung upon its gudgeon to any desired angle with the stock for the purpose of operating thereon at different angles. I have shown a sleeve screwed upon the gudgeon and bearing against the under face of the bed-plate C, which will prevent any misplacement of the cross-feed bed-plate D with reference to the bed-plate C.

The operation of the machine is as follows: 'A block of wood or metal is placed on one of the links bof the endless carrier and clamped thereto by the clamping device thereon. As has heretofore been explained, the endless carrier is continuously moving and the stock is placed thereon while the same is moving, and when the lug 19 upon the link I) strikes the bell-crank lever F F it throws the clutch E into engagement with the pinion E by means of the various levers in connection with said clutch-operating mechanism heretofore described. The pinion E is now fast on the shaft S and as the link continues its onward movement the lug b engages the reciprocating shaft S upon the tool-carriage bed-plate C and carries the same along with it, causing the pinion E to travel along the stationary rack E, thus rotating the shaft S and pinion E at the top thereof, which engages the rack H, carrying the tool-carriage block H forward. toward the stock.

It is evident that if the piece of stock and tool-carriage travel together in an approximately parallel direction and at the same speed the cutting-tool will operate thereon when moved across the same with as perfect freedom and effectiveness as if both were stationary with reference to any longitudinal movement and the tool simply moved across the same.

The endless carrier continues its onward movement, carrying the tool-carriage along with it, causing the cutting-tool to operate upon the stock until the lug g, which has been adjusted to limit the amount of cutting to be done upon the stock, strikes the pin g upon the lever G and swings the levers-G downward, drawing the clutch E out of engagement with the pinion E ,which, however, continues to rotate as it passes along the rack in the further movement of the carriage. The tool-carrying block H is now disengaged from the pinion E ,with which it has until now been connected, as heretofore described, and is free to return to its normal position. The weight W 3 is now in its raised position, and immediately upon the disengagement of the clutch E it falls to its lowest position, thereby returning the tool-carrying block H to its normal position, where it strikes the bracket 01 which limits its backward movement. During this return movement of the tool-carrying block the pinion E is evidently rotated through its engagement with the rack upon the tool-carrying block, but as the clutch E, which connects the shaft S with the pulley E at certain times, has disconnected the shaft from the pinion through the clutch-releasing mechanism above described, and the pinion E and shaft S are free to rotate with reference to the pinion E so that as the tool-carriage continues its movement in unison with the endless carrier the pinion E", which meshes with the stationary rack E, may rotate upon the shaft S in one direction and the shaft-and pinion E in the opposite direction, the tool-holder'being at this moment on its return movement. The returning of the tool carrying block is performed before the lever 0 reaches the stop a which is'adjusted so that sufficient time may be allowed for the tool-carrying block to'return to its normal position. hen the lever O strikes the stop 0 it disengagcs the reciprocating shaft S from the lug b and the weight W which has been raised to its upper limit, draws the entire tool-carriage back until the same strikes the limiting-stop 0, while the endless carrier continues onward, causing said piece of stock to be operated upon successively by the other tools, which are arranged along the frame of the machine. The tool-carriage is now in a position to operate upon the piece of stock following the one which has just been operated upon, it being understood that a piece of stock is placed upon each of the links I) by the operator. 7 hen the lever G is operated upon by the lug g, as has heretofore been described, it disengages the clutch from the pinion and at the same time carries the free end of the arm F down with it, thus giving a corresponding movement to the arm F on the opposite side of the bearing-ways A bringing the bell-crank lever F E into position to be acted upon by the lug b on the link following the link which has previously actuated the tool-carriage.

From the foregoing specification it is evident that various operations can be made upon the stock, and I have found that this machine is equally adapted for shaping metal as well as wood, and while I have shown and described only one set of tool-carriages upon one side of the endless carrier a similar arrangement may be had upon the opposite side, whereby both sides of the stock may be operated upon at the same time. In this case the device for clamping the stock to the links is arranged slightly different, so as to leave no projecting portions. The clamps can be easily arranged upon the ends of the stock so as not to interfere with any of the working portions of the machine.

\Vhile I have described the cutting-tool as a rotating cutter, it is evident that it is not necessary to employ rotating cutters, as other cutters may be used in shaping the block.

In the above specification I have endeavored to specifically describe the invention, but I do not,therefore, desire to limit myself to the exact construction thereof, as various alterations and modifications of the diiterent portions and combinations of the machine are numerous; but what I do claim as new and essential to the embodiment of my invention will be particularly pointed out in the following claims.

In the above the tool has been described as moving toward and away from the carrier, and the term transversely as used in the following claims is to be understood as such movement.

Having now described and explained my invention, what I claim as new, and desire to secure by Letters Patent, is
