Specification of Letters Patent.

Patented Mar. 10, 1914.

To all fr0/20m it may concern.'

l'e it known that I, THOMAS F. Moanissm', a citizen of the United States, and a resident of Nest Orange, in the county of Essex and State ot New Jersey, have invented certain new and useful Improvements in Drilling and Niching Machines, ot' which the following is a specitication.

The present invention relates generally to drilling and niehing machines, especially tfor buttons made of ivory nuts, and has for its main object an eflieient automatic machine that will properly drill and niche bnttons.

One Yt'eatnre oit the invention resides in means tor bringing a work holder and niching memberl toward and away from each other. combined with means Jfor imparting a combined oscillating and reciprocatiiig motion to the niching member. This may be accomplished in many ways, but preterably the niching member ismonnted on a slidably adjiiistable pivot, the said niching member oscillatingaround and Vibrating with respect to said pivot, and the said pivot reciprocating. 1n ett'ect the motion imparted to the niching member is a combined oscillating and longitudinally vibrating motion which imparted to the niching 1nember a plurality oit times in rapid succession to each cycle of the machine.

The niche in a button is the slot which is formed in the face oi the button and which connects the holes drilled in the button. rlhe object of this niche is to pro vide a thread groove below the t'ace of the button. To avoid wearing the thread, the niche must present no sharp edges to the thread. f lit is itor this reason that the niching tool is given the double oscillating and vibrating motion, the oscillating motion cntting the groove between the butto-ns and the 1vibrating motion rounding oil the corners where the niche joins the holes.

Other features oit construction, arrangement ot parts and combination ot elements will appear as the speeilication proceeds.

n the accompanying drawings, the invention is embodied in a concrete and preferred t'orm, but changes of construction may oit coarse be made without departing from the legitimate and intended scope ot the invention as set forth in the claims hereof.

In the said drawings: Figure l is a side elevation of a machine embodying the invention. Fig. 2 is a plan view with the button feeding .means removed. Fig. 3 is a transverse vertical section on line 25H3 ot' liig. l.

indicates the button feeding means, 2G is the work carrier or holder and 27 is the intermediate button delivery member which transfers the button 'from the 'feeding means to the work carrier or holder.

2S is the main reciprocating carriage on which the foregoing members are mounted7 and carrying also a reciprocating clamp slide 29 having the clamp 30.

The drilling tools are denoted by 31 and the niching tools by 32. These latter are mounted on the supporting member 34 of the niching tool slide 33 which moves in the guides rThe slide 33 is operated from the main reciprocating carriage by means of the connection 36 secured to said carriage as shown in `Fig. 13 and provided at the end adjacent to the slide 33 with a square collar 37 fitting loosely on the block 38 which is supported on the eccentric 39. r1`his eccentric has a flange 40 resting on the supporting member 34. Passing through the eccentric 39 is a bolt 41 secured to the slide 33. The supporting member 34 is provided with an aperture 42 so as to allow the said supporting member to oscillate and vibrate in a manner hereinafter to be described. The eccentric 39 is provided with an arm 43 secured to the lever 44 by means of the set screw 45 adjustable in the slot 46. rlihe lever 44 is pivoted at 47 to a stationary part of the frame.

The main reciprocating carriage 28 slides in the guides 48 and receives its motion from the worm gear 49, by means of the crank pin 50, cam 51, pivoted at 52 to the framework? and connecting rod 53 pivoted at its respective ends 54 and 55 to the cam 51 and slidev 28. The worm gear 49 receives its motion from the worm on the shaft 57, which latter receives its motion in any suitable manner, as by means of the pulley 58.

As the main reciprocating carriage advances toward the drilling` tools 31, the slide 33 will follow, owing to the connection 36. This movement, however, causes the lever 44 to turn the eccentric 89 thereby causing the slide 33 to lag behind advancing` movement of the main reciprocating carriage. When the main reciprocating carriage returns, the slide 33 will lag in the other direction.

The supportino' member 34 is attached to the slide 33 by means of a. slidably adjustable pivot constructed as follows: The supporting member 34 is provided with a slot 76 and the slide 33 has a slot 77 somewhat narrower than the slot 76. Seated in the slot 76 is a slidably adjustable block 78 in contact with the sides of the slot but small enough to leave the end spaces 79 unoccupied. A. pivot bolt 81 passes through the block 78 and is adjustable therewith.

Mounted on the supporting member 34 is the eccentric 59 through which passes the bolt 60 on which is the pinion 61, said bolt 60 having a bearing in the socket 33a of the slide 33. rEhe bolt 60 is adjustable in the eccentric 59 by means of the two set screws 62 whereby the eccentricity of the pinion can be varied. Meshing with the pinion or gear 61 is a sector 63 mounted to oscillate on the stud 64. The gear sector 63 is operated from the countershaft 65 which receives its motion from the shaft 57 by means of the pinion 66 and gear 67. The shaft 65 carries a disk 68 having a slot 69 to which is attached a stud 70 of the connection 7l which latter is provided with universal joint 72 and 73. The connection 71 is secured to the gear sector 63 by means of the eccentric stud 74 which is adjustable by means of the handle 75. The stroke of the sector is adjusted by moving the stud 70 in the slot 69.

The action of the sector 63 causes the pinion 61 to oscillate, and, with it, the eccentric 59. rlhe oscillation of the eccentric causes the supporting member 34 to oscillate around the pivot 81, and also to vibrate longitudinally of the block 7 8, in quick succession a plurality of times to each stroke of the slide 33.

rlhe work holder 26 has a rotatable member 26a mounted on the main reciprocating carriage 28 and interposed between the drilling and niching tools, and rotates in a plane at right angles to the movement of the said carriage. This rotatable member is provided with pockets 83 and is partially surrounded by a stationary peripheral raceway 84 having a cam 85 which is adjustable by means of the screw 86 and is adapted to engage the buttons 87 to move the same radially inward to center them with respect to the tools. vided with projections 88 to prevent the edge of the buttons from moving sidewise, and carries pins 89 by means of which it is rotated. rEllis rotating motion is imparted intermittently by means of the pawl 90 pivoted at 91 to the transverse slide 92. rlhe transverse slide obtains its motion from the. main reciprocating carriage 28 by means of the slotted link 93 engaging with the roll 94 on the transverse slide and pivoted at 95 to a stationary part of the machine.

96 is an arm carried by the main reciprocating carriage and connected by means of the link 97 to the slotted link 93. The motion of the reciprocating carriage 28 thus moves the transverse slide 92.

rihe raceway 84 is provided with a chute 98 located adjacent to the intermediate button delivery member 27. rllhe member 27 is pivoted at 99 on the bracket 100 and is provided with a. supporting shoulder 101. Mounted on the transverse slide 92 is an upright 102 which is connected to the member 27 by the following means: 103 is an arm. on the pivot 99 connected to a link 104. This link is connected to a pivoted lever 105 on the upright 102 by means of the spring 106 and by means of a pivot 107.

108 is a stop on link 104.

1li/Then the transverse slide 92 moves, it will7 through the connections just described,

rlhe member 26 is further pro-V cause the member' 27 to oscillate, the stop 108 normally preventing the spring 106 from exerting its force to bring the outer ends of the link 101 and lever 105 together, but if a button is jammed so as to prevent the member 27 from completing its oscillating motion, the lever 104.- will yield and the spring 106 will take up the motion imparted by the transverse slide. When the member 27 turns in one direction the shoulder 101 will uncover the feeding opening 106L in the button feeding means .25, and a button will drop into the said intermediate member 27 and will be supported by said shoulder. 1When the intermediate mechanism 27 turns in the opposite direction the shoulder 101 will move from underneath the button, and the latter, being no longer supported will drop down the chute 98. At the same time the shoulder 101 will close the feeding opening 106a.

Mounted on the pivot 1081 of the bracket 100 is a yielding guard consisting of an arm 109 provided with the finger 110 adjacent to the feeding` opening 106. This guard is normally held in its uppermost position by the spring 111, and when a button becomes jammed in the feeding opening 106L the guard will yield, and then push the button back into the button feeding device 25 as soon as it is free to do so.

The but-ton feeding means 25 may be of any suitable construction and consists of a casing 112 having a rotatable dial 113, with pockets 114-, in front of which is a hopper 117. The rotatable dial is driven by the worm 115 and worm gear 116. This button feeding means may be provided with means for turning the buttons right side up as shown in Patent No. 547,571.

The auxiliary slide 29 which carries the clamp 80 for the work holder extends longitudinally of the main reciprocating carriage 28 and is mounted in the guides 118. Normally the clamp 8O is held closed against the work holder by means of the expansion spring 119 seated on the stem 120 and bean ing against the abutment 121 of the carriage and the shoulder 122 of the auxiliary clamp slide 20. Means are provided for opening said clamp, in this instance constructed as follows: 123 is a cam, lever pivoted at 1241 to the adjustable bracket 125 of the reciprocating carriage 28. This cam lever' has a cam slot 126, one side of which is resilient on account of the spring tongue 127, the said slot engaging with a roll 128 on the auxiliary slide 20. 129 is a cam provided with a slot 180 sliding on the stud 181 of the framework. One end of this cam is connected to a rocking lever 132 pivoted on the framework at 188 and provided with a slot 1841 engaging the stud 135 of the reciprocating can riage 28. As lthe reciprocating carriage 28 travels in one direction the cam lever 123 will ride up on the cam L29, which latter is then, owing to its connections, moving in a direction opposite to that of the rcciproeatf ing carriage. The cam slot 126 acts on the roll 128 to move the auxiliary slide 29 independently in the reciprocating carriage 28 sul'liciently to open the clamp 80. As the cam lever 123 passes the end of the sliding cam 12S), the member 186 on the reciprocating carriage 28 engages with the stop 187 on the arm 158 pivoted on the framework at 185). This arm has a spring 1-10 which engages the stud 141 on the cam lever 123 and moves it down quickly behind the cam 129, thus allowing the spring 119 to close the clamp 30. (.)n the return stroke of the reciprocating carriage 28 the beveled surface 1-1-2 of the cam lever 123 moves the hinged leaf lil-8 of the cam 129 to one side so that the clamp remains closed and permitting the cam lever 128 to pass the cam 129.

11i-il, is an ejector which passes through the aperture 145 in the carriage 28 and expels or loosons the finished button.

The drilling' tools 31 and niching tools 32 are of any suitable construction, but the particular arrangement preferred is as follows: The converging drilling tools 81 are mounted in the bearings 146 on the slide 147 which is adjustable by means of bolts 111:8. Ou the slide 11117 is a. bracket 111:9 supporting the steady rest 150 adj usi-,able in the guides 151 of the bracket 1119 by means of the bolt '152. 158 indicates turnbnckles whereby the tools 31 are adjusted. Motion is imparted to the tools by means ot' the belts 154-. passing over the

pulleys

155 and 156. The pulleys 156 are on the power shaft 157 which carries the fast and loose pulleys 158 adjacent t'o which is a belt shifter 150.

The niching tools 82 are carried in the

bearings

160, 161 and 162 mounted on the supporting member 84, and converge in the same manner as the drilling tools.

The bearing 160 consists of a casing 168 having a vertical slot 161. lVithin the easing is a stem 165 which receives the screws 166, passing through the slot 116-1-, These screws 166 carry the brackets 167, through which the tools 82 pass.

The bearing 161 comprises a casing 168 having two spindles 160 and 170 connected together by means of the pin 1.71 screwed into 16S) and having' a head 172 sliding in the slot 173 of spindle 170. The tools 82 pass through two brackets 171iwhich are secured respectively to the spindles 16S) and V1.70 by means of the screws 175 passing through the holes 176 in the casing.

The bearing 162 is formed of a casing 177 having two independent spindles 178, each provided with a threaded stem 179 having a tlmmbscrew 180. The tools 82 pass through the brackets 181, which latter `are attached to the spindles 178 by means of CFI screws 182. Rotation is imparted to the niching tools 82 by means of the pulleys 183, belt 184: and pulley 185 on the power shaft 157.

rlhe operation of the machine is as follows: Upon motion being imparted, the reciprocating carriage'travels toward the drilling tools 31, thereby causing' the clamp 30 to be opened. The work holder 2G is then rotated so as to position a button blank in line with the drilling and niching tools. llhis position is indicated in Fig. 7 by 186. it this time also the oscillating intermediate device 27 delivers another button blank to the work holder. The dial 118 is rotating constantly and is always ready to deliver a blank to the intermediate device 2?. As soon as the work holder 26 has been turned one step, the clamp 8O moves against the work holder 28 and clamps the button. All. during this period the main reciprocating carriage 28 has been approaching the drilling tools, and the niching tools have followed it, but owing to the eccentric 39, the niching slide 83 lags behind and the niching tools 82 have receded in time to permit the rotation of the work holder 26. 'lhe drills now engage the button 8'?, entering the said button from the back and drilling the holes 188 in the button part-way through. rfhe reciprocating carriage 28 now begins its return stroke and moves the button out of engagement with the drills. The nichingl tools also move backward, but, owing to the eccentric 89, at a less rate of speed than the carriage 28, and the result is thatl the niching tools engage the face of the button and remove the material in line with and between the holes 188 by cutting the niche or thread groove 189. The niching' tools oscillate and vibrate continuously by reason of the eccentric 59 so that the niche is cnt on a curved line 190 shown in llfig. 22. The oscillating and vibrating movement of the niching tool is shown in llig. 20 where the two dotted positions of the tool are shown nearer the button blank than the full line central position. r1`he line 19() in Fig. 22 approximately shows the line of movement of the niching` tool. As the carriage 28 reaches the end of its movement, the ejector 144i enters theaperture 145 in the carriage 28, and ejccts the button in line with said ejector. This button was cted upon by the drilling' and niching tools daring the cycle preceding the one 1 have described and was moved into position in alincment with the ejector when the work holder was rotated during' the forward movement of the carriage 28.
