and 10) is provided with a radial guideway 19 in whi chis mounted a slide 20 adjustable by means of a screw 21. A pin 22 carrying a block or driver 23 freely slidable within a longitudinal guideway 24 in the link .3 is provided on the slide at one end thereof.

The link is pivoted at its lower end to the bed at 25 and at its upper end at 26 to a block 26 adjustably secured to the table. The screw 21 is journaled at one end 111 a bearing 27 and a bevel gear 28 thereon adjacent the bearing meshes with a' bevel gear the throw of the link 3 and the reciprocation of the table.-

An indexing dial 34 is provided for indi-' cating the amount of rotative movement given to the hand wheel 33 and the position of the block 23. In adjusting the block 23 from zero to maximum, the shaft 30 must be given several rotations. In order to properly record these rotations, the indexing dial 34 is adapted to be rotated from the shaft 30 at a greatly reduced speed through thefollowing mechanismz An internal gear 35 is secured to the drum 13 and aneXterna-l gear 36 is freely mounted eccentrically of the shaft 30 onaneccentric portion 32 of the sleeve 32' and connected to the'dial 34 by means of a screw 37. The internal gear 35 has 'a greater number of teeth than the external gear 36. The

gears

35 and 36 are al ways in mesh and as the sleeve 32 is rotated, the meshing position'of these gears travels around the shaft 30. It will be seen that for each such rotation, the dial 34 is rotated rel ative to the gear 35 the distance of the dif ference of the number of teeth on

gears

35 and 36. Thedial may be marked to clearly indicate the effect of any adjustment of the hand. wheel on the table stroke, This mechanism forms a part of the subject matter of a copending applicationhereinafter specified.

The slide 20is bifurcated at one end, providing two

legs

20 and 20 fitting in grooves 19 and 19 on opposite sides of the guideway 19 (Figs. 9 and 10). A wedge block 38 having inclined

sides

33 and 33 engaging complemental surfaces within the bifurcated portion of the slide is adapted to be forced inwardly of the slide to wedge the

legs

20 and 20 thereof into tight clamping engagejment with the drum. As illustrated; the

block 38 entirely surrounds the screw 21, although, as will be understood, such construction is not essential to a realization of the invention. The means for forcing the block into clamping'engagement comprises a shaft 39 preferably integral with the block and extending through the tubular shaft 30. A nut 40 is threaded to the end of shaft 39 and has bearing against the sleeve 32 which at its inner end bears directly against the drum.

After adjustment of the slide 20 by means of the hand wheel 33, the former may be tightly clamped in adjusted position by tightening the nut 40. It should be noted that the means for operating the parts just described is remote from the parts themselves and is readily accessible,it being only necessary for the operator to swing open the pivoted cover member41. this stroke adjusting mechanism just de I do not claim scribed as a part of my invention, the same"v being the invention of Herbert .S. Fullerton and comprising the subject matter of a'co pending application, Serial No. 436,964, filed January 13,1921.

As the table is recipr'ocated through the oscillatory movement of the link 3, it will be noted that the distance betweenthe pivots 25 and-26? is different for different positions of the table and such distance is constantly changing as the table is being reciprocated. To compensate for this difference, I preferably make the linkin two relative sliding parts, one telescopically mounted for free sliding movement within the other. as illustrated in Figs. 1 and 2 the outerlower .part 3 of the link is pivoted at 25 and the upper inner part 3*" is pivoted at 26.

justing

blocks

42 and 43 are provided in the I guideways in the part 3 of the link for taking up lost motion and looseness caused by wear or otherwise. I

It is often desirable and necessary to adjust the operating position of the table on the bed and for this purpose, I provide the following improved mechanism.v The block 26 is mounted in a dove-tailed recess 44 eX- .tending lengthwise of the table at the under sidethereof (Figs. 1, 2, 3, 5 and6). A screw 45 journaledv at one end 46 in thetable end has threaded engagement with the block -whereby the position of the block within the table recess may be adjusted. The block has a portion thereof cut away toform a recess: within which is mounted a wedge bloc-k4? having a straight side 47 engaging. one'wall of the table recess and an inclined. or tapered rotating the shaft50 the wedgeblock 47 may be moved in one direction or the. other to clamp the block 26 tightly within the recess 44 or to unclamp the same.
