cZZ whom it may concern: is tlirned ofi true to produce an outer shoul- Be it itnovvn that I, dot-m hie-Luann, i def 6 adapted to receive thereon and formcitizen of the United States, residing at a hearing for the adjacent portion of the r'z'z zidei'ice in the county of "Providence and riih of'the revoluble drivingelement or pul- 'tete of iiho'de island, have invented cerley'H, as clearly shown in Fig.1.

The inner end portion of as the shaft is reduced in diameter and extends through a recessed concentric disk r and is rigidly held against movement by a nut h. [it the some time, a collar r, adjustably secured to the shaft and bearing against the rear face of the pulley-hub, in coiipcrntion with said disk 7 and shoulder 5 serves to accurately maintain the pulley in position both 11ClWiS and centrally; the disk 9' also revoinhle d adapted be actuated for crease-311g in at one operation a corresponding iiiiinher of holes.

P. The disk 7' also forms a backing for w merts herein described are assembled to pro- The cylindrical holder E is shown as consisting of upper and lower segments, each having an inwardly extending peripheral rim 0 and base flange 0 Between these flanges are mounted a plurality of drillholders proper e, of brass, in the meeting faces of which are formed a number of uniformly spaced, semi-circular, registering holes e extending longitudinally of the machine, adapted to receive the shanks of the respective drills d. I prefer to provide the drills with thrust-collars (Z arranged in a' staggered form, and having the adjacent faces of members a grooved at right angles to said holes 6 to receive these collars, as shown at 6 Figs. 5 and 6. Said collars serve to prevent the revoluble drills from moving endwise. After the drills have been mounted in the holder the whole is clamped together-by meansof bolts 6 Obviously, this latter operation is preferably done before the holder is positioned in the bit I).
The inner holder or drill-actuating memberD, preferably made of brass, is movably mounted in the eccentric recess 7 formed in the member N of the revolubledriving-pulley. The holder, D, which may be diskshaped, is, as shown, provided alongits center line with a series of holes f, to freely receive the inner or .ofiset end portions d of the respective drills, the degree of said ofiset being the same as the amount of'eccentricit-y. Fig. 7 shows the relation of the disks center to the normal center of the machine, wherein the small dotted circle it indicates the eccentricity or throw during each revolution of the machine. See also Fig. 8. 7
It will be seen, referring to Fig. 5, that a portion, (2 of the shank of each drill intermediate its ends is ofiset or bent at an angle,
thus forming a crank whose circular throw or movement is the same as the length of the concentric circle before referred to. 6
Assuming, now, that the parts or eleduce an organized multiple drilling machine, substantially as shown in the drawings, the manner of imparting continuous simultaneous rotary movements to each and all the drills may be stated as follows: The action ofthe revolving driving-pulley H imparts a like movement to the eccentrically recessed, vertically arranged inner member N, secured to the pulley, and'causes the disk D, or crank-disk, as it may be called (in which are journal ed a series of drills d), movably mounted in said recess, and in cooperation with the centrally mounted, s tationary drill holder E, to move bodily in varying horizontal parallel planes, corresponding to or limited by the amount of said circ'ilar throw h, whereby each and all I newness of the drills in the series are positively roany an int on, the outer edge or on the as member D, when mounted and as described, is adapted to describe at such point during a revolution. of the pulley a circle having the same diameter as h.
Obviously, the number and arrangement of drills which may be journaled in the face of the disk D is limited only by its area, in connection with the spacing distances apart of the drill-bearings and the amount of eccentricity or throw of the'crank-circle h, it being understood that the cranks d of all the drills should normally lie parallel with one another, that is, when economy in spacing is considered, so that the cranks will pass one another without striking.
As thus devised and arranged, the work or articles operated upon, as for example,
the backs of brushes, is moved to and fromthe drills.
If desired, the machine may be operated' .by fpower transmitted through a drivingsha t F, revolubly mounted in a bearing t and having a spur-gear t adjustably secured to the inner end of said shaft, adapted to mesh into teeth t formed on the outer part of the hub of the pulley H, as shown gitudinal grooves formed in the joint or meeting faces thereof, and a plurality of laterally off-set drills having fixed thrust collars, the latter being mounted in said longitudinal grooves and having other portions of the drill revolubly seated in Said transverse grooves and in the holes of said eccentrically movable member, for tlid purpose set forth.
