, Application filed July 31, 1899 Serial No. 725,577. (No modeh) T0 ctZZ who???) it may concern.-

Be it known that I, CHARLES D. AMES, a citizen of the United States of America, residing at Portland, in the county of Jay and State of Indiana, have invented certain new and useful Improvements in Tub-Makin g Machinery, of which the following is a specification.

My invention relates to certain improvements in tub-making machinery of the class designed to trim up the ends of the staves after the same have been placedin the trusshoops, which is called leveling, prepare the inside ofthe smaller end of the tub for the croze, which is called .howeling, cut the groove around the inside of the smaller end of the tub, which is called F crozingfiand trim up the inner and outer sides of the larger end, which I will call beveling. The purpose of my invention is to combine in one machine mechanism for performing these operations upon the tub in the most convenient position, the devices composing said mechanism being arranged to work automatically and so timed as to operate to the best advantage.

To such end the invention consists in-cer-- tain novel characteristics because of which the tub may be handled to the best advantage in pnttingit in the machine and taking it-out of the same, and all of the various operations may be accomplished without effort or attention on the therefrom. means of which this is accomplishedwill be described in this specification andthe essential features thereof pointed out in the claims.

The description in the specification will be specific as to the devices illustrated in order to make the same as clear as possible, but it arm swung into position, a tub being shown '15 15 of Figs. 9 and 16.

Fig. 25 is a detail vertical transverse section of the leveling-tool and adjacent parts adapted to engage the larger end of the tub, the line of section being indicated at 25 25 in Figs. 1 and 26. Fig. 26 is a detail plan of said tool and its carrying-block. Fig. 27 is a detail vertical transverse section in line 27 27 of Fig. 24; and Fig. 28 is a side elevation of a tub showing the same as it appears after it has been operated upon by the machine, a portion of the tub being broken to further illustrate the same.

Referring to the drawings, the particular machine here illustrated consists of a suitable framework, driving-gear supported therein, a rotating and vertically-reciprocating shaft bearing aninternal chuck, devices for operating upon the two ends of the tub brought successively into operation by the vertical movement of said tub, and devices for causing said vertical movement and for stopping the rotary movement of the tub when the cycle of operation is complete.

The framework of the machine is made up of atable A, (see Figs. 1, S, and 9,) supported uponv legs a a a a and the standard B at one side of the table, in which the outer end of the'main driving-shaft is journaled. The driving-shaft is lettered O and is provided with tight and loose pulleys c 0 outside of the frame. Within the frame it bears a mitergear 0 in mesh with a miter cl upon a vertical shaft D and journaled in two cross-pieces a a, secured to the frame above and below the table, respectively. The mitergear (1 is feathered to the vertical shaft and is confined vertically between the miter and the lower bearing. The shaft D is vertically movable in its bearings, said movement being controlled by a weighted lever E,bearin g a Weight e at its free end and vpivoted to the frame and to the vertical shaft. The pivot to the frame is at e, and the opposite end of the weighted lever is pivoted to the shaft by means of a sleeve e (see Figs. 9 and 15,) running in a groove'e in a collar 6 fastened upon the lower end of the vertical shaft. The tendency of the weight is to hold the shaft in its highest position, the lowering of the shaft, which occurs during the operation of the machine, being resisted at all times by the gravity of the weight. A foot-lever F is secured to the inner end of the weighted lever, by the depression of which the operator may overcome the Weight and lower the vertical shaft.

Upon the top of the vertical shaft is fixed an inside chuck d, (see Figs. 1, 4, 5, and 9,) which holdst-he trussed tub while the same is in the machine. This chuck is screwed upon the top of the shaft and is vertically adjustable thereon. Two jam-nuts d d are shown upon the threaded portion of the shaft beneath the chuck to prevent the rotation of the latter upon the shaft.

The cutting or trimming of the tub is effected by rotating the latter in contact with relatively-stationary knives, those for operating upon the larger end, which is the lower end when in the machine, being located upon a stationary disk G, secured in position upon the cross-piece a of the frame. The knives for operating upon the smaller end of the tub, which is at the top of the machine, are located upon a vertically-moving arm H, supported upon standards at diagonally-opposite corners of the bed, so as to be capable of horizontal oscillation upon one of the standards to throw it into or out of operative position and to be vertically-movable upon the other standard to effectthe successive operations upon the tub by causing a vertical movement of the latter. The standard 1 is preferably a round post'secured to the frame and braced bythe diagonal bars i f". The rear end of the arm H is pivoted to it between vertically-adjustable collars z' 1). The vertical adjustment of the arm is to adapt it to different lengths of tubs. The standard J is preferably a flat bar secured to the frame and suitably braced therefrom. It is provided at the top with a vertically-adj ustable side bracket j, (see Figs.

10, 11, and 24,) bearing a guide j, the top of which extends obliquely upward and away from the arm to bring certain devices upon the tool-carrying arm upon the upper end of the bracket j. Said bracket j is secured to the standard J by means of a bolt passing through the slot in the bracket and one of a series of holes j in the standard, the slot providing for a close adjustment and the series of holes for an adjustment of greater extent. The frame of the tool-carrying arm H is shown as composed of two side bars h h, (see Figs. 17 and 24,) secured together at the pivoted end by means of a cross-piece 7L and at the opposite end by means of a strut 77. and bolt 72. the bolt also extending through a handle it in line with the strut, by means of which the arm may be conveniently manipulated. The pivoted end of the arm is secured to the standard by means of a collar h held between the collars it, before referred to, the arm being pivoted to said collar h by means of horizontal screws h h (see also Figs. 3 and 4,) giving to said arm both a vertical and a horizontal pivotal motion upon the standard.

Upon the under side of the side bars of the arm is an H-shaped plate h", secured to the side bars and spaced apart therefrom by means of interposed bars h, rabbeted to form ways for tool carrying slide plates K M. The plate K is provided with a leveling-tool 7c and a howeling tool 10 the latter being supported in a block k fastened to the plate by means of bolts k The plate M contains two grooves m m, and a block N, bearing a crozing-tool 'n, is bolted to the plate M by means of bolts n 12. passing through'the slots. The slide -plates K M are connected by means of links 70 we (see Figs. 1 and 2) to a lever O, pivoted between its plate H, the two links being pivoted to the ends to the tub. To support bracket q upon the lever on opposite sides of its pivot and the lever also being pivoted at one end to a link 0, extending to an angle-lever 0, pivoted between the side bars of the arm H at o and extending beyond the pivot in an approximately-horizontal arm 0 (see Fig. 10,) adapted to rest upon the bracketj, above referred to. The oscillation of the angle-lever upon its pivot moves the slide-plates toward or from each other, and a springo, connected to the hub of the angle-lever and ver 0, tends to draw the two plates toward each other and to withdraw the howeling and crozingtools carried thereby from the tub. Both of these tools work upon the inside of the tub and are advanced into or withdrawn from the same by the oscillation of the angle-lever o. It should be noticed that the links m are not parallel and that as the lever 0 swings upon its pivot to advance the tools to their work the link 7t approaches a position in line with the pivot of the lever (9 before the link m the result of which is that during the latter part of the operation of the crozing-tool the advance of the howeling-tool has been substantially checked.

When the tool-carrying arm H is in its working position, it rests upon the lower edge of the it when swung out of such position, a rest P (see Figs. 1, 2, 3, 4, and 5) is-provided, supported from the frame and from the brace 2' and made in two parts, bolted together by means of a series of holes 19 and a boltp to give it vertical adjustability. Fig. 1 shows the tool-carrying arm upon the rest, which leaves the chuck free for the putting on or taking off of a tub, and Fig. 2 shows the arm in working position, its weight sustained upon the tub and its free end held against horizontal movement between the standard J and the bracketj.

The drawing down of the tool-carrying arm is efiected by a vertically-reciprocating rod Q, (see Fig. 3,) guided between its ends by means of aslot qand a bolt q in said slot secured to the standard J, the lower end of the rod being pivoted to a lever g pivoted to the frame at g and hearing at its opposite end a nose and a catch (1 (See also Figs. 1 and 5.) The rod Q is made up of two parts longitudinally adjust-able one upon the other by means of a bolt q, a series of holes (1 in one part and a slot in the other. The rod is held yieldingly in its upper position by a spring g secured to the lever g and to a standard J. The lever g is oscillated in the opposite direction by means of a double cam R upon a shaft r, journaled in boxes r'r (see Fig. 5,) secured to the frame and bearing upon the opposite side of the frame a worm-gear 1' rotated by a worm 9' upon a shaft 1 (see also Figs. 4, 6, and 7,) journaled in boxes 1* r and carrying at its opposite end a pulley 7- geared, by means of a belt T to a pulley 0 upon the driving-shaft O. The vertically-reciprocating rod Q is provided at the top with a laterally-extendin g to the 1e:

end q, adapted to engage the top of the toolcarrying arm H, as seen in Fig. 11, and the operation of the cam R is to draw down the tool-carrying arm, holding the leveling-tool upon the lower end of the tub until its work is completed, then forcing the howeling-tool to its work, and then advancing the crozingtool and at thesame time bringing the'larger end of the tub down upon the disk G, where it is operated upon by inside and outside beveling-tools and a leveling-tool supported upon said disk. These beveling-tools are carried by two blocks S S, (see Figs. 1, 21, 22, and 23,) the tools themselves being lettered s s. The blocks-are secured to aslide S provided with slots .9 3 by means of bolts passing through the slots and clamping the blocks to the plate. The slide is guided in ways 9 in the disk G, the sliding motion of the plate being radial to the disk, so that the adjustment for different sizes of tubs may be easily made and at the same time the slide and tool may be permitted to move in the ways 9 to follow any irregularities in the tub. The lower leveling-tool T (see Figs. 1, 25, and 26) is supported in a slide t, guided in radial ways g in the disk G and is radially adjustable in the same manner as the howeling-tools s 8'.

When the tub is finally brought down so thatthe lower leveling-tool trims it to exactly the right length, the operation of the machine is automatically stopped by means of. the catch g For this purpose the tight and loose pulleys c c are provided with a belt-shifter consisting of two fingers u u, (see Figs. 1 to '7, inclusive,) upon a sliding rod U, guided'in the frame and crowded toward the position shown in Fig. 3 by a spring 11?. The pulley c is the loose pulley. The stopping of the tight pulley c and the working parts of the machine is efiected by means of a brakeco'nsisting of a shoe V, secured to a lever 11, pivoted at one end to the brace 2 (see Figs. 6 and 7,) and at the other end to a link o, (see Fig. 3,) which together with a link 0 pivoted to the other end of the link 11' and at its lower end to the frame, form a toggle operated by a depending arm 11 secured to the rod U. The shoe V is crowded toward the pulley c by a spring u when the parts are in the position shownin Fig. 3. When, however, the rod U is crowded toward the left in said figure, the toggle raises the brake-shoe at the same time that the belt is shifted to the tight pulley.

A collar M3 is secured to the rod U and has pivoted to it one end of a lever W, (see Figs. 1 and 2,) pivoted between its ends to the frame at w and at its opposite end to a link W, extending forward and pivoted at its opposite end to a lever W pivoted'between its ends to the frame at w and having a forwardly-bent hooked end Z02, (see Fig. 9,) the depending hook of which extends beyond the front of the bed 'in one position to engage a vertically-oscillating lever X, (see Fig. 5,)

slidingly pivoted to the frame at m by means of a slot 00, giving to the lever a longitudinal movement in addition to that of oscillation upon the pivot. Said lever X is pivoted near its opposite end to a vertically sliding and oscillating plate 00 (see Figs. 12, 13, and 14,) pivoted by means of a slot 00 to a bar no, secured to the frame. A spring 00 tends to raise the lever X and a spring a (see Fig. 13) tends to crowd it to the right in Figs. 5 and 12. The spring 00 is secured at one end to the rear of the bar a? and at the other end to a bolt 00 extending through a triangular hole 00* in the bar and fastened to the plate 00 The lever X extends downward at its free end and is provided with an upturned point a adapted to engage with the catch g This upturned point tends to hook under the catch g as the latter comes down and to slide off of the top of the same as the latter is raised. The pointed end of the lever is guided by means of the triangular hole on and the bolt 00 as clearly seen in Fig. 13. As the lever is forced down by the catch its point is withdrawn from beneath the latter by the oblique side of the hole. As the catch raises, however, it simply slides the lever back as the bolt rides along the upper side of the hole until the point of the lever is cleared.

A foot-lever Y (see Figs. 4 and 9) is pivoted to the frame at y and has an upwardlyextending arm y resting against the rear side of the lever W The operation of the machine is as follows: The tub, which has been set up in the ordinary truss-hoops, is inverted and placed upon the chuck d. The swinging arm His brought over the tub and crowded down upon the same and toward the right until the top of the arm is caught by the hooked upper end of the rod Q. The operator then presses his foot upon the foot-lever Y until the catch 10 engages the lever X, which starts the machine and locks all of the parts in operative position. The catch (1 upon the lever q is moved up and down by the cam R once during the cycle of operation. In its upward movement it forces the lever X out of its way without disturbing the locked portions of the machine; but at the end of the cycle of operation it moves downward, striking the end of the lever and disconnecting the parts which have been locked by the depression of the lever Y. The leveling-knife upon the swinging arm first operates upon the smaller end of the tub to trim the same. The howeling-tool upon the arm bevels off the inside of said smaller end of the tub, as the arm is brought downward by thehooked rod Q, until said rod is lowered sufficiently to throw both the upper leveling and howeling tools out of operation, as is shown in Fig. 24, where the under surface of the arm adjacent to the crozing-tool has crowded the tub downward sufiiciently to move it out of range of both the upper leveling and the upper howeling tool. The downward motion of the arm is continued sufficiently for the bellcrank lever o to strike the bracket j, thereby throwing the crozing-tool outward to the extent necessary ,to cut, the croze in the portion of the tub which has been operated upon by the upper howeling tool. Said downward movementof the arm also crowds the tub down upon'the disk G, subjecting the larger end to the operation of the lower bevelingtools, both inside and out, and also to the leveling-tool upon said disk. The operation of the lower leveling-tool is completed at the instant the highest part of the cam R passesfrom beneath the nose of the lever g The spring (1 snaps the nose of the lever downward, engaging the hooked end of the lever X, and lowers said lever sufficiently to release the hook 10 which looks the driving-gear in operative position. The releasing of the hook permits the spring a to shift the driving-belt, and the shifting of the same releases the brake-shoe, which is brought down on the driving-pulley by the spring 1;. This stops the driving-gear and completes the cycle of operations necessary to finish one tub. The raising of the hooked rod Q by the lever (1 permits the spring 0 to swing the lever 0 about its pivot, thereby withdrawing the crozing-tools from the croze and swinging the bell-crank-lever 0' back into its normal position.

Many of the particular elements of the mechanism herein shown and described may be varied almost indefinitely, and-for that reason I do not limit myself to the same, as the broad principles of the invention are entire-1y independent thereof.
