' ib s! 12 extends across the front of the fr'nzne I, and on this limit are are 'e'd two boxes 13',in each of which is mounts a, beering-block 14. Screws 15 extend through the front and back end of the said boxes 13 and engage the rosisoctive hoarinz.lalooks 14. By means, oi those screws 15 the said bearingblocks can be adjusted in their rospmztivo boxes 13 and looked in any (losimd ositiom The stave-carrying frame 17, on w ioh the stave/is clamped and "properly bent before ICE ' machine for the end plates and the bearing-block 14 by means of trunnions 18, which are preferably formed' integral with the said frame 17,so that the-said stavecarrying frame 17 can be rocked toward or away from the cutter.

It is to be understood that the adjustment of the bearing-block 14 in the boxes 13 will determine the bevel on the edges of the staves, and consequently the diameter of the barrel formed from thestavesmnd this adjustment is made wlien'the machine is first assembled and tested in the shop, and therefore this adjustment will not be changed unless it is desired to make barrels of greater or less diameter than the ones produced by the machine as originally assembled. NOW as this adjustment must be very exact it'cmt be best accomplished by one especially skilled in this particular art, and therefore when the machine is set up and tested before it leaves the shop the bearin in the boxes 13 so t at themachirie wi lproduce .a barrel of a determined. diameter, and then a mark or rooveisformed ineach of the bearingbloc rs and a similar marker oove b is formed in each of the boxes 13 in ine with the respective grooves formed in the bearing-blocks, so that when the machineis reassembled i n.1ts permanent positioii the in t two grooves a and b in therespective ingblocks and in the. res ectl't'e boxes to register with each other. he machine can also betested for forming joints on staves l' barrels oi" various diameters, and similar grfooves a a and b b can be formed in the respective bearin -blocks and in the respecr ti ve boxes, thus orining a scale or index by means of which any mechanic can adjust the reducing staves suit-able i'or forming barrels of any required diameter.

My adjustable stops for limiting the movement. of the stave-carrying frame toward or away from the cutter and my device forsu porting the stave-carrying l'rameagainst t \e endwisc strain of the cutter are arranged as follows: On each sideofthe frame 1 is secured a plate), to which are secured plates 20 and 21, which extend at a right angle therefrom. In the respective plates 29 and 21 are arranged screws 23 and 24, res ectivcly. 'A block 25 extends acmss the 1 ate 19 between the plates 20 and 21. On the rcs wrtivc ends of the said stave-carrying frame Ware formed lugs 26, which are so arranged that when the frame 17 is rocked back and forth the said lugs 26 will travel between 2| and across the ace of the block 25. The adjustment of the screws 23 determines the limit of the travel of the frame 17 toward the cuttcr-head,and the adjustment of the screws 24 determines the limit of the backward movement thereof.

-blocks 14 are adj ustcd pro jpr adjustment of the bearing-blocks e boxes can be secured by causine the ear- The screws 23 by limiting the movement of the stave-carrying frame 17 toward the cuttcr prevent the stave from being uselcssly cut away and also make it possible to produce a very smooth surface on the joint, for when the stave-carrying frame becomes stationary the knives will continue to pass over the jointed edge of the stave and plane it very smoothly. The blocks 25 serve as side bearings for the stave-carrying frame 17 and support it against the the operation of the cutter while cuttin a jointon thestave. Ononeofthescrews24 see Figs. 17 and i8) is arranged a sleeve 150, in which is formed'a slot 151. Asmall stud 152 is secured on the screw 24 and extends into the slot 151. A handle 158 is secured to the sleeve 150. By turning the sleeve 150 on the screw 24 it can be caused to' pro'ect beyond the end of said screw 24, and thus prevent the stavewarryin frame 17 from swinging back as far as it otherwise would. The especial object of this auxiliary stop will'nppear hereinafter.

On to )oi' the stave carrying frame 17, at

each en thereof, is formed a seat/30, having I a curved surfacecorresponding to the curveture of an arcof a circle having the same diamcter as the barrel which will be formed from the said staves. These seats 30 serve as rests for "the ends of the stave when clamped on the stave-carrying frame. Stops or guides 31. are formed on the respective seats 30, which prevent any longitudinal movement of the stave and also serve to bring the center of the stave exactly over the center rest, hereinafter described. The stops olr guides 31 are'prcferably formed so that t icv may be readily inserted between them and are preferablv of suflicient height so that the center rest will not project above them when raised to its highest position. As some-strives vary slightly in length, flat springs 32 may be provided at the ends of the respective seats 30 and are preferably secured to and arranged paral cl with theguides 31. These springs 32 have equal resiliency and sufiicient movement to accommodate such accidental variation in length as may exist between staves desi mod to be assembled in the samesizcd barre and they will therefore alwa s engage the ends of the staves and center t e staves,exactly over the center rest. A series of ribs or corrugations 154 may be formed on the respective seats 30, as shown in Fig. 15. The object of these ribs is to prevent short stares which do not come in contact with the ends of the seats, from being shifted by the operation of the cutter.

The devices for clamping the ends of the ataves on the end seats are mounted and arranged as follows: At each end of the stavecarrying frame near the top is pivotally endwise strain caused by flare outwardly in order that a stave ject of this cons motion 1? is'therefore no mounted a bell-crank lever end of which lS' seat.

A slide 91 extends through the rest 79 above the bar 80 and is arranged to slide in the said slideway On the bottom of this slide 91 is formed a rack 92. On the top of theslide9l is secured a block 93 by means of n bolt 94 and u pin 95.

.block 93 and the relative arrangement of the gage-plate 96 is such that when the said block has raised the center rest to tion for any starve the gage-plate will be in position to come in contact with the outer,

edge of the stove, indicating that the center rest is at the that particular stave -A shaft 99 is mounted in to the operator right height for y a suitable bearing 100, formed in theplete 77. On the shaft 99 are formed gear-teeth 101, arranged tomesb with the rack 92 on the bottom of the slide 91. On the endoi the shaft 99 is mounted a hand-wheel 102; The bearing near one end of the shaft 99 is split, and n bolt 103 is mounted in the usual menner; so that/by turning the bolt the split ends can be brought together and lock the shaft 99 against rotation. A key 104 is provided for turning the bolt 103.

The stop for limiting the movement of the stove toward the on tter-head while'it is beinlg adjusted on the frame 17 is arranged as 0 lows: In the to of the rest 79 is journelode shaft J06, on w arm 107. In the rest 79 slow theshaft 106 is pivoted a box 108 by means of a. pin 109. A rod is pivotally secured to the arm 107i at one end, and its other end extends into the =ro'tnted and m the proper pos'i-'- ich is.k e ed a hook-shaped ,rying frame, means box 108 and is provided with a head 111. On the rod 110 between the head 111 and the end of the box 108 is mounted a, coiled spring 112. On the end of the shaft 106 is keyed a crank-arm 113. In the rest 79 below the box 108 is formed a bearing for a shaft 114. An arm is formed integral with the said shzif t 114 and is connected with the arm 113 by means of a link 116. In the end of the shaft 114 is formed a socket 117, in which is pivotally secured one end of a shaft 118 by means of a pin 119. The said shaft 118 extends across the frame and passes through a loose bearing 120, formed on the frame 17. The end of the shaft 118 is turned down, so as to form a depending finger 140, arranged to come into contact with a stationary lug 121, formed on the'frame '1. This lug 121 is provided with en eccentric head 122, so that by turning the lug an adjustment can be secured between the said lug and the end of the said shaft; 'The operation of this device is as follows: When the frame 17 is rocked back from the cutter-heed, the finger on-the end of the shaft 1 18'c0mes into contact with the stationar lug 121 and the, shaft 108 is turn rotetesthe shaft 115, which through its operative connection rotates the shaft 106, swinging up the hookshaped arm 107 until it pro ects above the top of the rest Z9. As the arm moves upthe rod 110 is pulled out from the bo'rr108, compressing the s ring 1 1 2." When the frame 17 1s rocked bac lmv'ard the cutter-head, the coiled spring 112 will draw the rod 110 back intothc box 108, causing the arm 107 to swim down andout of the way of the cutter.

When a stove is irregular or too wide to be used, it is noccs'saryto out off the excess or waste portion before the stave is jointed, and

therefore the sleeved50 is turned out'beyond the end of the screw '24; which prevents the stave-carrying frame from swinging back far enough to 6' crate t e stop on the center rest.

A rock-s aft '12 is mounted in suitable bearings formed in; the sides ofthe frame 17. To this shaft'nre keyed two curved nrms 122, which extend u and are arranged to come into contact wit rtheedgeoflthe stave when placed on the frame 17 and eline the stave and hold it in its proper position thereon until clamped on the seats ,A is keyed to the shaft 125,

secured a weight 129, which causes the acid ,armis 127 to press tightly against the stove.
