SPECIFICATION forming part of Letters Patent No. 642,212, dated January 30, 1900.

Application filed July 16, 1896. Serial No. 599,406. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM S. DOIG, a citizen of the United States, and a resident of New York, (Brooklyn,) in the county of Kings and State of New York, have invented a certain new and useful Improved Machine for Making Battened Boxes, of which the following is a specification.

My invention relates to nailing-machines, especially to machines for making battened boxes, wherein battens may be nailed and the boxes nailed together in consecutive operations.

In making up packing-boxes it is the practice for purposes of economy to form the sides, ends, top, and bottom of the box from two or more pieces united by battening-that is, by nailing on cross-strips or battens and clenching the nail, and the parts thus formed are then nailed together to form the box.

The machine shown herein comprises the combination, with nail feeding and driving mechanism adapted to be adjusted toward and away from the face of the machine, of a clenching apparatus which may be automatically thrown into and out of gear with the machine by the act of changing over from battening to box-nailing, or vice versa, and the details in aid of the same.

To enable others skilled in the art to make and use my invention, I will describe the same, having reference to drawings hereto annexed, whereof- Figure 1 is a front elevation of a machine illustrating my invention. Fig. 2 is a side elevation thereof. Fig. 3 is a horizontal section on line 3 3 of Figs. 1 and 2. Fig. 4 is a side elevation of the two-rimmed band-wheel and cooperating friction-roller of the operating-gear of the platform I-I. Reference to Figs. 1, 2, and 3 will show the relative location of these operating parts in the machine. Fig. 5 is a front elevation of the same. Fig. 6 is a side elevation of the upper part of the machine, showing the sliding carriage which carries the nail-pan and nail-boxes and guides the nail-punch-carrier bar, which carriage is moved to simultaneously adjust these parts back and forth with respect to the work and the front of the machine. Fig. 7 is a front elevation of the same. Fig. 8 is a plan View of the lower section of the carriage to clearly illustrate the mechanism for moving it backward and forward. the sliding nail-punch-carrier bar D, whose location in the machine is clearly illustrated in Figs. 1 and 2. Fig. 10 is a plan View of the nailing cross-head. Fig. 11 is a plan View of the slide which carries the nail pan and feeder. Fig. 12 is a plan view of the. table and clenching-anvil. Fig. 13 is a longitudinal section of the anvil. Fig. 14 is an end sectional elevation of the anvil. Fig. 15 is a vertical section of the table, anvil, and mechanism for operating the table, showing the table H in its lowest position. Fig. 16 shows the same parts with the table raised. Fig. 17 is a front elevation of the table. Fig. 18 is a side view of the sliding bar and cam for operating the table. Fig. 19 is a plan View thereof.

The main frame F of the machine is erected and made fast on a base B, which frame and base sustain all the principal operative parts of the machine.

\Vithin the frame and reaching from side to side thereof is the usual nailing cr0ss-liead D, (shown clearly in Figs. 2 and 10,) which has an upand-down reciprocative motion imparted thereto in any usual manner-in this instance by a pitman A connecting with a crank a on the main shaft A. The nailpunches are carried by a thick bar D, (see Fig. 9,) termed a nail-punch-carrier bar, which is placed parallel to and is movably at tached to the cross-head D, being adapted to be moved in and out toward and away from the face of the machine and the said crosshead and retained in any desired position, whereby besides the capacity to nail up boxes it is enabled to drivethe nails into the parallel margins of battens of different widths,as determined and adjusted by the operator.

At the top of the main frameF are flanges or ribs ff, (see Figs. 1, 2, and 14,) extending from front to rear, which act as supports and bearings for a double sliding carriage G, (see Figs. 6 and 7,) and lower down the frame F has grooves f 2 f 2 reaching from front to rear,serving as additional supports and bearings for said carriage. The carriage is in two sections-upper and lower. The upper section consists of a broad bar g and two end pieces transverse thereto, which are rabboted out Fig. 9 is a plan view of' on their under edges to match the thickness of flanges f of the main frame, and the whole rests on and slides over the flanges f, being held in place by gibs g 9 (see Fig. 7,) that are fastened to the rabbeted portion of the end pieces aforesaid.

The lower section g of the carriage G consists of a rectangular frame, of which the short sides or ends 10 enter the grooves f in the mainframe and slide therein in unison with the upper section 9. The upper and lower sections g and g are permanently united to each other and maintained at a fixed distance apart by means of rods g the upper ends of which are secured in openings g in bosses 9 on the upper section, while the lower ends pass into like bosses g on the lower section and are there retained by setscrews 9 tapped into the bosses 9 The nail-supply pan E, the feeder E and the nail-chutes E are all movable horizontally, being connected to carriage G by brackets g 9 made fast to the upper section g, or otherwise.

The nail-boxes E, which receive the nails from the chutes E and hold the same until they are driven by the nail-punches carried by the nail-punch-carrier bar, are secured to the front bar of the lower section 9 of carriage G and move therewith, being laterally adjustable thereon.

D is the carrier-bar to which the nailpunches are made fast, such bar being arranged parallel with the cross-head, as shown. This bar, with the nail-punches attached thereto, is constructed to admit of being laterally moved and adjusted toward or from the crosshead and at a greater or less distance from the face of the machine, as before mentioned, to adjust the punches simultaneously, thus maintaining their relative position with the nail-boxes on the carriage G. For this purpose the cross-head D is provided at each end with extension-brackets d, (see Figs. 2and 7,) which are furnished with ribs or tongues d on the outside of the ends, reaching across the ends of the cross-head. The nail-punch-carrier bar D is fitted to the under side of said brackets d and has transverse slideways formed by gibs 01 secured to bar D, to match the tongues or ribs d of the cross-head D, and the nail-punch-carrier bar D slides on these gibs when it is moving out or in, as aforesaid, and rises and falls with the nailing cross-head.

The nail-punches d are made fast to the bar D in any convenient manner. In this instance they are screwed into punch-heads d pose the nail-punch carrier D has two projecting arms d Fig. 9, the ends whereof are perforated to receive the rods g of the carmoving part of the machine.

riage G, carrying the nail-boxes, thus coupling said carriage with the nail-punch holder and insuring their movement in unison, and this without obstructing the reciprocative motion of the nail-punch carrier D in the naildriving action of the cross-head, such carrier D moving freely on said rods 9 The means for producing the lateral movement of the carriage G and nail-punch carrier for adjustment preferably consists, as here shown, of a screw, as that passes through the rear bar g of the lower sect-ion or frame g (see Figs. 8, 12, and 13) and is threaded into a nutf in the main frame F, the outer end having a collar 9 on either side of said bar and a hand-wheel g for turning the screw.

The principal work-support is a horizontal platform H, carrying a two-part clenching device provided with cam mechanism to work the same to adapt the machine for alternately nailing battens onto the pieces which are to form parts and clenching the nails and then nailing together the box, including such parts-i. e., the bottom, ends, sides, and top.

To maintain the platform H in position horizontally, it has a downward extension or plate 71, which is strongly braced to the table by knees h, all by preference made in one solid casting, and the ends of the vertical plate are grooved -for slideways to match vertical tongues or ribs f f formed on the inside of the uprights of the main frame F.

When nailing on battens, the nails are clenched as they are driven, and in the ma chine being described the work of battening and box-nailing is done on a supplementary table H, forming part of a two-part clenching device. The surface of this table is partly formed of a hollow clenching-anvil P, the table H having an opening corresponding to and receiving the top or clenching-head of the anvil P. (See Fig. 12.) The clenching-head is shown as divided into three sections 19 having supports 19. The table H has a relative vertical motion as to the anvil P, consisting in dropping the table slightly or rais ing the anvil the distance necessary in clenching nails. movable portion and the anvil is stationary. Hence the table when at its highest position is above the surface of the anvil, as seen in Fig. 16; but when completing the clenching of the nails its surface is flush with that of the anvil, as seen in Fig. 15, and the condition would be the same if the anvil were the movable portion and the cam mechanism made to raise that instead of the table.

The clenching device is worked by cam mechanism, as seen in Figs. 15, 16, 18, and 19, where T T indicate cam-bars sliding in ways 19 Fig. 13, and actuated from a shaft or some On these bars T are cams tt, cooperating with cams or projections H correspondingly located on the under surface of the movable portion of the clenching device to raise and lower the same In this instance the table is the to operate it. The cam-bars in this instance are worked by a shaft R, located in brackets f at the rear of the main frame F, which has a crank-arm '1', furnished with wrist-pins 7*, which are mechanically connected to the cambars in any suit-able way. The shaft may be operated in any convenient manner. Here it is worked by the nailing cross-head, which is furnished with upright rods S S, secured to brackets (Z made fast to the cross-head, and hence moving with it. Upon the said rods are lock-nuts s s, adjustably held in place, as by set-screws 3'. Such nuts in the reciprocating action of the cross-head are brought in contact at the desired moment with other crank-arms r fixed on shaft R, thus turning the shaft and working the cam mechanism of the clenching device to operate the same. In practice the nuts 5 s are adjusted to cause the clenching to take place at the moment the points of the nails reach the top of the clenching-anvil, at which momentthe parts occupy the relative position seen in Fig. 1G, and Fig. 15 shows the position of the parts when the nails are clenched.

The operative mechanism of the clenching device and the means in the machine for operating the same are constructed for unshipment and disconnection, (from each other,) and this may be done by mechanical means. In the present machine I have embodied a scheme whereby connection and disconnection or unshipment are made to take place antomaticallyand in the act of lowering and raising the platform carrying the clenching device when changing from battening to boxnailing. For this purpose the crank-arms a" of the shaft R on the nailing-machine engage with the cam-bars of the clenching device by open connections. These for simplicity consist in having the wrist-pins 0" to take into faws if of the cam-bars T which are 0 en on l a P the upper side.

In changing the operation from battening to box-nailing the platform is lowered to its boX-n-ailing position, and the cam mechanism of the clenching device hence remains inert. hen resuming the battening and clenching, the platform being raised to the battening height, the cross-head being elevated as before, the open jaws t of the cam-bars-T'readily find and embrace the wrists r of the crankarms 7' and the clenching device is again ready for battening and clenching.

To increase the working capacity of the machine, I economize time in lowering the platform H to its place for making up boxes after nailing on battens, and vice versa, by providing poweractuated means therefor driven from the main shaft, thereby avoiding the delay attendant upon the operation of the platform by hand. The means preferably employed comprises a screw mechanism applied to the platform H. Large screws I I (see Figs. 1, 2, and 3) are made fast to this platform by their upper ends in brackets h by screws 71?, and their lower ends are encircled by sleeves z 71, whose interior is threaded to match said screws I, while the exterior of the sleeves have a spiral gear formed thereon. These spiral gear-sleeves are confined between brackets b and the base I3, but are free to rotate around the screws I. The gears are engaged and revolved by other gears t, matching them, made fast by sleeves t on a horizontal shaft 1, journaled in two uprights b on the base B and having a bevel-gear 2' made fast thereon at one end. The shaft 1 is revolved from the main driving-shaft A through the following train of gearing: A horizontal shaft J, carried by brackets 1'), (see Fig. 3,) has a bevel-gear j, which drives the shaft 1 by the bevel-gear i thereon, and shaft J receives motion from a shaft L above (see Fig. 1) through link belt 1 engaged by sprocket-wheelsj and Z, carried by the shafts J and L, respectively. The shaft L also carries a friction-wheel Z that is driven by a wheel M having rims M M and located on the end M of ashaft M which carries a small spur-wheel M, (see Fig. 3,) that meshes into and receives motion from thelarge gear-wheel A on the main shaft A. This constitutes the power mechanism for raising and lowering the platform. For more precise adjustment of height when required I provide a manuallyoperated device, here shown as consisting in a hand-wheel Z, fixed on the front end of the shaft L, (see Figs. 1 and 3,) by which through the sprocket-wheels Z andj and allied gearing the sleeves i 'i may be turned and the platform adjusted to the finest graduation in height.

In connection with the means for raising and lowering the platform by power derived from the main shaft a reversing device is employed to instantly reverse the motion of the sleeves e' i. For this purpose the frictionwheel Z is brought alternately in contact with the outer periphery of the rim M or the inner periphery of the rim M of the double-rimmed wheel M To permit this, the shaft L is journaled in a sleeve 70, forming part of an upright swinging arm K, fulcrumed by its lower end to a bracket Z) (see Fig. 5) on the base B, and the required swinging motion is imparted to the sleeve 7s and inclosed shaft from a handlever n, fulcrumed to a bracket f on the main frame F, which hand-lever is connected to arm K by a rod N and link 0. (See Figs. t

and 5.) This reversing device is available for operating by hand or power.

The nail pan orhopperE is oscillated by any suitable means. In the drawings a sprocketwheel A (see Fig. 2,) made fast on the main shaft A, gives motion by a link belt A to a shaft A through a smaller sprocket-wheel A of just half the diameter of wheel A The shaft A is mounted in an adjustable bearing b in a bracket 5 made fast to the standard B A fixed thereon, to the free end of which is pivoted a link A which may be connected by a rope or chain (not shown) to the nail- The outer end of this shaft has a crank pan, and passes over a pulley (not shown) running on a suitable bearing located above the nail-pan.

The machine is thrown into operation by momentary pressure on a foot-lever M (see Fig. 2,) which communicates with and works a coupling-clutch on the main shaft A, and after one stroke of the nailing cross-head down and up is automatically thrown out of operation and stopped by means of a selfacting knock-out. This stopping and starting mechanism is preferably the same as that described in the patent to Smith and Doig, dated May 18, 1886, No. 342,268, to which reference is made for such description.

The nailing of battens on the pieces that are to form the sides or ends of the box to be made, followed by the nailing up of the box, is or may be carried on continuously.

The operation of the machine is as follows: Beginning with the platform H, it being in its highest position, a box end or side with its batten thereon is placed on the table, and the machine is started and continued in operation until all of the parts of a box are prepared. The operator then uses the lever 11. to bring the friction-roller Z intov contact with the proper rim of the pulley M for mechanically operating the screw mechanism of the platform H to drop the table to the position required for nailing up the box, the handwheellbeing used when necessary to complete the adjustment and determine the precise height. Thereupon the operator proceeds to nail up the box from the prepared battened pieces. In the operation of so dropping the table the cams for operating the clenching-table H are automatically disconnected from the means of operating them, for which purpose the cam-bars T, which embrace the crank-pin d on the rock-shaft lever B, are made with jaws 1 opening upward, so that in such downward movement of the platform they will automatically detach themselves from the crank-pins r r, and in like manner when the platform is raised for again nailing on battens they will automatically reengage said crank-pins.

The platform, table, and anvil constitute a support for the work,and the means forbringing the clenching device into action operate in harmony therewith.

It will be observed that when the platform is in its lowest position the boxes may be nailed together, a normal nailing operation being effected without clenching the nails, and that upon raising the platform the clenching apparatus is automatically put in action to effect the clenching of the nails, the said clenching device -or apparatus operating in harmony with the nailing mechanism.
