BORING-MACHINE FOR BRUSH-BACKS.
Application filed February 9, 1912.
To all whom it may concern Be it known that I, \VILLIAM G. LIEBIG, who am a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements 1n Boring-Machines for Brush-Backs, of which the following is a specification.
This invention relates to machines for boring holes in wooden blanks used for brush backs, and has for its object an improved device adapted especially for use with rounded brush backs used for carpet sweeper brushes and the like, in which several rows of holes are to be bored in predetermined order.
In the drawings :Figure 1 is a perspective of the assembled device. Fig. 2 is an elevation of the back of the machine. Fig. 3 is an elevational View of the left end of the machine, as viewed from the front. Fig. 4 is a plan View of the master roller and of the blank whose boring is desired, at about the level of the line y-y of Fig. 2. Fig. 5 is a side elevational view of the reciprocating slide carrying the actuating hook which engages the master roll, to 1'0- tate it about its axis. Fig. 6 is a plan view of this slide, partly in section.
Projecting from the base 1 of the machine is a bracket 2, which supports a traveling table 3, from each end of which rise struts 4, through which engage adjusting and holding screws 5 and 6 for the master roll 7 and the wooden blank 8 respectively. \Vithin or on one face of one or both of the struts are rotatably mounted a series of intermeshing gear wheels 9, by which rotative movement of the master roll 7 is communicated to the blank 8. The upper portion of the base is bent over so as to overhang the table 3 and its supported parts, and init is rotatably journaled the spindle ll of the chuck 12, in whose lower end is removably held the auger 13. Rotative actuation is communicated thereto .by means of the belt 14, (see particularly Fig. 3) which passes over the pulley 15 on the upper end of the stem 11, and which is preferably protected by the shield 16. The belt 14 passes over the pulley 18 which is keyed to the shaft 19 on which is mounted the pulley 18, to which actuation is communicated from the engine by means of the belt 17; for the sake of compactness and efficiency of operation,
the belt 14 is preferably led over the-idler Specification of Letters Patent.
Patented Jan. 19, 1915.
Serial No. 676,657.
The horizontal operating shaft 21, which extends across the rear of the machine at about the level of the table 3, has mounted on it the flywheel 22, over which the belt 17 passes to communicate actuation thereto,
and also the cams or eccentric disks 23 and 24. Of these the cam 23 has on one face the wrist pin 25, over which engages the knuckled end 26 of the link 27, which is pivoted to the rear end of the lever 28, by which the gimlet carriage or boring member 12 is depressed to effect the boring of holes in the wooden blank. By suitable proportioning of the length of the lever and of the diameter of thecam and the rotative speed of theactuating power belt, the desired frequency and degree of throw or descent of the gimlet can be secured. The cam 24 has running over its periphery the roller 29 which is journaled in the end of the lever 30, which is pivoted at 31 to the upper part of the frame of the machine, so that its short arm 32 extends downward in .a nearly verticalposition to the level of the horizontally reciprocating bar 33, which is preferably'mounted on the upper end of the pivoted link 34, whose lower end is pivoted to the bracket 34 which proiects from. the frame or base of the ma :hine. This short arm 32 being rigid in its angular position with respect to the lever 30, and
consequently swinging therewith. moves to and fro as the lever 30 rises and falls, there- .by moving the slide 33 forward and back for the purpose now to be described.
to the forward end of this bar 35 is the rear end of a hook 38, whose point engages over the studs or knobs 40 on the master roll 7, and which is yieldingly held thereupon by the leaf spring 41 which presses upon its top. The possible tendency of the hook 38 to rise too high as it rotates the master roll in its rearward travel, is counteracted and regulated by means of the stop bracket 47 which depends from the bent-over upper portion of the frame or base, its height being regulated by the nut $8. This bracket preferably carries on its lower end a roller 4-9, which directly engages the hook38. By the rotation of the cam 24:, by which the lever 30 and its connected and coiiperating parts are actuated, the actuation of the master roll 7 through an arc of desired size is accomplished at each cycle of operations of the device. This is brought about through the medium of the hook 38, which is pivoted to the lower forward end of the short arm 32.
Farther along on the shaft 21 from the cam member referred to, that is, toward the right hand end of the machine is supported on the sleeve 45 a cam 50, on one face of which is located a'wing 51, and on the other face of which is located a projecting ratchet 52 which is adapted to be engaged by the hooked lower point of a branch or bracket 53 which is attached to the lever member 30, in such a way that each time the lever 32 and with it the branch or bracket 53 swings because of the raising of the lever 30, the cam member 50 is rotated through an arc whose size is determined by the number of teeth which peripherally constitute the ratchet 52; for example, if there are eight teeth in the ratchet, the cam member ,50 is, at each actuation, moved through a 45 degree angle. "The number of ratchet teeth in each case corresponds with the number of rows of pins or studs in the masters roll 7 at any circumferential point, and correspondingly with the number of holes to be complementarily bored in the wooden blank 8. When, through the repeated actuation of the master roll 7 rotatively, as already described, the boring of one set of holes has been completed, the cam member 50 has, by the corresponding repeated pulls upon its ratchet portion 52, been so rotated that its wing piece ,51 engages the head 54 of the pivoted. lever 55, whose forward end carries a spring pressed pawl 56, which engages in the serrated edge 57 of the rear side of the table 3, pushing it to the right to a degree sufficient tothrow the next row of studs or knobs 40 on the master roll 7 under the hook 38. The boring of the next circumferential row of holes is then proceeded with in like manner,.
and at the end of that period the completion of another rotation by cam 50 again throws the pivoted lever 55 and moves the table 3 one more notch in its travel toward the right of the machine. YVhen the last row or girdle of holes has been bored through the reachingof the correspondingly located set of studs 40 by the hook 38, the right hand end of the table 3 has been projected so far to the right by the repeated actuations of the lever 55 that the ne vtactuietion n h me ee fo ces the gh and end of the table against the bent-over or forwardly-inclined finger 59 of the lever 58, which is pivoted at 60 in position to swing horizontally when thus engaged by the table end. This lever when in its normal and unactuated position, as shown in full lines on Fig. 4-, engages with its heel 61 over the top of the rod 62, which may be slightly beveled, in such a way as to hold it down against the upward pull of the spring 63; when, however, this lever 58 is thus tripped, the pull of the spring-63 shoots the rod 62 upward; this being connected with the link 6%, whose upper end is connected with the control lever 65 of the clutch member by which the fly wheel. 22 is operatively connected with the shaft 21. This stops the further action of the roller and blank-actuating parts, and forces upon the attention of the operator the fact that the boring of the-holes in that articular blank has been completed, and that a new blank must be inserted between the holding screws 5, and the table 3 again moved to its initial starting position at the extreme left of its path of travel, when the clutch 65 being again thrown to operative position, the alternate raising and lowering of the link 27 through the rotation of the cam 23 is begun once more, in turn actuating the parts already described. The return of the lever 58 to its interfering position, as regards its inclined linger 59, across the eX- 'treme end of the path of travel of the table 3, is eifeeted by a pull of the operators hand, after the table has been moved to its starting position at the left side of the machine.
The adjustable support 43 which rises from the forward edge of the table 3 engages under the center portion of the blank 8, just clearing its surface as it rotates, thereby preventingit from bending to any extent or possibly breaking when being pressed upon by the operation of the boring member.
'The arrangement of parts hereinabove described can be used under varyingconditions and to meet special needs with slight modification without departing from the spirit of my invention; for example the arrangement of actuating belts and pulleys may 'be varied somewhat, or changed in whole or in part to intermeshing gear wheels, levers and the like; and for the disclosed mounting of the cam member 50 of the rotating shaft 21 which contemplates the employment of a sleeve 45 to avoid to the utmost the influence of the rapidly rotating shaft upon the slowly rotating cam member 50 an independent bracket with suitable bearings, projecting from the suppprting frame may be substituted.
