RICHARD LESTER VLCOX, OF YVJAL"EBBUR-Y, CONNECTCUT, ASSIGNOR T THE WATER- BBY FARREL FOUNDRY AND MACHNE COMPANY, OF WATERBURY, CONNECTI- CUT, A CORPCRATICN OF CONNECTICUT.

SHAVING Application led July 31,

To all fr0/0m t may concern.'

Be it known that l, RICHARD LESTER WiL- oox, a citizen of the United States, residing at l/Vaterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Shaving Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to new and useful improvements in shaving machines, having particular reference to a type of machine designed for trimming the head and shank of a bolt, screw, or similar article.

It is the object of this invention, among other things, to provide an apparatus whereby bolts, screws, or the like may be automatically shaved and capable of making one or more cuts either upon the shank thereof, the top and bottom of the head, or any one of these or any combination, as may be desirable; to hold the bolt with mechanism that has no movement parallel to the axis of the bolt; to provide suitable supports for the tools and adjustments thereof; and in these and many other ways to provide a machine that will be highly efficient, composed of the fewest possible parts that are readily assembled and capable of producing the desired results efficient-ly and economically.

To these, and other ends, my invention consists in the shaving machine, having certain details of construction and combinations of parts, as will be hereinafter described and more particularly pointed ont in the claims.

Referring to the drawings, in which like numerals of reference designate like parts in the several figures;

1n the practice of this invention a machine is provided whereby blanks are delivered from a chute connected with a hopper of any preferred form, the details and construction of which constitute no part of my present invention, and are carried from the chute delivery point to a position wherein its aXis is substantially coincident with that of the holding device, then applying pressure upon one end of the bolt so as to project the shank thereof into the holding mechanism and at the same time withdrawing the transfer mechanism into register again with the hopper chute for another blank. This holding device I prefer to construct substantially as herein shown and described wherein it consists of a chuck having no endwise movement and surrounded with an enclosing ele-V ment which does have an endwise movement -and as a result thereof closing 'the clutch.

having no endwise movement, there is no possibility of axial movement of the bolt by reason of a frictional engagement of the chuck therewith. After the chuck has closed onto the bolt, one tool takes a chip off the shank to size and true the same, and square up the underside ofthe head and a second trues off and shapes the top of the bolt head, after which the tools are withdrawn and a knockout device cjects the finished bolt from the chuck and it drops into a receptacle conveniently arranged to receive it.

In one form of the embodiment of my 1nvention, 1 provide a bed 10 which is supported upon legs 12 that rest in a drip pan 13, also supported upon similar legs 14. This yis a convenient method of supporting the bed but of course is ronly one of the many forms that may be used equally as well as the one shown.

VFixed to the bed adjacent to one end thereof is a bracket 15 in which is journaled one end of the main shaft 16 that is rotatably mounted in the brackets 17, 18 and 19, also connected with the bed. Upon said main shaft 16 is a balance wheel 21 and al cone pulley 2O driven by a belt as is usual, although the shaft may `be connected directly'to a motor or other source of power, if so desired. Also ournaled in the brackets 15 is an intermediate shaft 22 having a gear 23 thereon that meshes into a pinion 24 on Athe shaft 16, by means of which thc said shaft 22 is rotated. On the end of the sh aft 22 opposite the gear 23 is a pinion 25 which meshes into and drives the gear 26 fixed to the cam shaft 27, journaled in the brackets 15, 17 and 18. Upon this cam shaft are fixed the cutter cams 28 and 29, grip cam 30, knockout cam 31, push-in cam 32, and transfer cam 60.

Adjustably secured to the bed 10 is a spindle bracket 33 having three standards 34, 35 and 36 thereon. Tn the standard 34 isv fixed a bushing 37 containing an auxiliary bushing 164, and having a collar o8 thereon supporting a thrust ball bearing 39. A similar bushing 40 is fixed in the standard 35 and supporting a similar thrust ball bearing 41. In the standard 36 is a bushing 42 having a conical bore within which is mounted the journal sleeve 43 moved endl wise in one direction within the bushing 42 vto ` a threaded collar 48, locked by a check nut y ce 49. A coil spring 50 between one face of the Aweb of the pulley 46 and the thrust bearing A41 exerts its tension so as to move thev ChllCtk sleeve 45 axially within the bushing 40 and journal sleeve 43 toWard the rightV as shown in Figure 6. Movement of the chuck sleeve 45 in the opposite direction is derived from the grip cam 30 through the rock lever 51 carrying a cam roll 52 and provided with a yoke 53 which straddles the collar 54 threaded on said spindle. The 'rock lever 51 is pivotally mounted on the stand 165 adj ustably connected with the bed 10 by the pin 166. A. ball bearing 55 held against endwise movement by the lock nut 56, and centered by the collar 57 having an interior conical face takes the end thrust of said collar 54.

l/Vhen the chuck sleeve 45 is moved to the left from the position shown in Figure 6, the chuck, hereinafter described, is opened and is closed by movement of the chuck sleeve in the opposite direction by the gripping cam 30 through the means above described. Within the chuck sleeve 45 is a spindle 58, which is held against relative rotation by a pin 61 fixed within the sleeve 45 and projecting into a slot 62 in said spindle. This cooperative rela-tion permits relative endwise movement of the sleeve upon the spindle but not a rotary movement.

Fixed on the spindle 58 adjacent to one end thereof is a hand-wheel 63, which is journaled within the auxiliary bushing 164, and with the nuts 64 holds the spindle 58 against endwise movement.

Secured within the outer end of the chuck sleeve'45 by the pintle 65 is a chuck collar 66 that encircles and incloses the chuck 67 threaded into the end of the spindle 58. This chuck is of theV Hendley type, made preferably of a single piece of metal with an enlarged conical head and split lengthwise for a portion of its length by the slots 68. The bore of the chuck collar 66 is conical in part to correspond with the head of the chuck 67 whereby relative endwise movement of either the chuck or the sleeve in one' direction causes a compression pressure upon the head of the chuck and closes its jaws upon any article held within the bore 69 thereof.

In the mechanism herein shown as the spindle 58 is held against endwise movement, the chuck is also so held and the compression of the chuck is obtained primarily through the endwise movement of the chuck sleeve 45, the jaws closing onto the article therein at substantially a right angle to the axis thereof and Without endwise movement. The article Within the chuck will be gripped by this mechanism exactly where placed, without possibility of its position being shifted axially by any endwise movement of the chuck, as is usual in the chucks adapted for devices of this character.

The mechanism for ejecting an article from the chuck comprises in part the knock- .upon a slide bracket 90.

out rod which moves freely within the s indle 58 and havin@ a head 71 thereon.

projecting into the bore of the chuck 67. Encircling the knockout rod near one end is a spring 72 which lies between the spindle 58 and an adjustable collar 78 upon said rod and exerts its tension so as to hold the rod in its outermost positions.

This knockout rod is actuated, to eject an article from the chuck, from the cam 31 through the lever 74, that is pivotally connected by the pin 76 with the stand 75, adjustable upon the bed 10. A cam roll 77 upon this lever is in contact with one face of the cam 31. The stand 7 5 and lever 74 are both provided with a plurality of openings 78 and 79 respectively whereby the shifting of the relative positions of the lever in relation to the stand to register any one of the holes 79 with any of the holes 78, the length of stroke of the rod 70 may be varied.

The position of the lever 74 is limited in one direction by a stop pin 80 that lies within the screw 81 threaded through the arm of the bracket 83, adjustablv secured to the bed 10 and having a check nut 82. This knockout rod 70 may be used also as a stop to limit the position of the article placed within the chuck 66, in which case a plunger 84 is substituted for the stop pin 80 (Figure 2). The plunger is formed with a shank 85 that is surrounded by a coil spring 86 lto normally move the knockout rod to the right in Figure 6. Check nuts 87, upon the shank 85, limit the inward position of the plunger 84.

As the blank is moved into the chuck, with this modied form of device it engages the head 71 of the knockout rod and moves the same rearwardly against the tension of springl 86, which maintains it in contact with the blank, resisting the inward pressure thereof so that the possibilityof the blank being moved into the chuck too great a distance is entirely eliminated. Thus the blank is held securely between the stop and push-in mechanisms, and all blanks will register in exactly the same position. The blanks to be operated upon in the machine herein shown consists generally of the ordinary bolt blank having a round shank and either a polygonal or round head as may be desired. These blanks are thrown indiscriininately into a hopper 88fwhich is supported upon a standard 89 from which they are conducted to the transfer mechanism through the chute 91 adjustably secured This hopper mechanism and the means for conducting the blanks to the transfer mechanism constitutes no part of my present invention and any form of such mechanism as will successively present the blanks at the discharge end of a chute will operate equally as well.

The slide bracket is vertically adjustable through manipulation of the screw 92 threaded in the bed 10, which bears against the lug 93 and is held in its adjusted positions by the check nut 94. The bolts secure the bracket 90 to the bed and pass through slots 96 to permit relative adjustment of the bracket upon the bed. By means of this adjustment the blank at the point where it is engaged by the transfer mechanism may be maintained in proper alignment with the chuck 66.

The numeral 97 designates the tranfer slide which has a reciprocatory movement within the slide bracket 90, deriving itsmotion from the transfer cam 60 through the rock lever 98 pivotally mounted on the bracket 18, having a cam roll 99 thereon which is held in contact with the face of the cam 60 by the spring 100 secured to the rock lever 98 and a fixed part 101. A rock lever 102 is pivotally mounted upon the bracket 90 by means of the stud.103 and connected with the rock lever 98 by the connection-rod 104 and to the transfer slide 97 by the link 105. Universal joints 106,

. of a well-known type, connect the connectionrod 104 with the rock levers 98 and 102. Threaded through the stud 107 by which the link 105 is pivotally connected with the slide 97 is a stop-screw 108 which in its iii-- ward position abuts against a liked part of the bracket to limit the inward movement of the slide 97, thus enabling the transfer mechanism to move the blank so that its axis is coincident with the axis of the chuck 66. f

Secured to the slide 97 is a block 109 to which is pivotally secured the clip 110 by the pintle 111. Opposite the outer end of said vclip 110, a finger 112 is fixed to said block so that the shaik of the blank, herein designated by the numeral 118, is held rtherebetween under pressure derived from the spring 114 that lies within a recess in the block 109 and bears against a plunger 115 which contacts with the clip 110 and the tension of which is varied by the screw 116. In Figure 12 the parts are shown in their relative positions as the lowermost blank in the chute 91 is engaged between the clip 110 and the finger 112, the former being held slightly open by its engagement with the beveled lower edge of one side of the chute 91. Thereafter, through the movement of the slide 97 this blank is transferred from the chute to a point where its axis is coincident with the chuck 66, this inward position being limited as before indicated by the stop-screw 108.

The outer end of the blank 113 is supported as it drops from the chute by the plate 170 which is connected with the adj ustable block 169 by the screws 172. This block 169 is movably mounted toward and away from the slide 97 upon the rods 168 and secured in its adjusted positions by the screws 171.

The push-in mechanism to be hereafter described now engages the end of the blank and moves it into the chuck 66, and the slide 97 thenretur-ns to its former position, the clip moving' upon `its pivot mounting, against the tension of the spring' 114-, and passes under the blank which is then held against lateral movement within the chuck. As soon as the clip 110 is released from the blank, the spring 114, through the plunger 115, returns the clip to the position subst-antially as shown in Figure 12, ready to receive the next succeeding blank in the chute 91 `and the transfer operations are automatically continued as above described.

Adjustably secured to the top of the bed 10 is a bracket 117 within which a slide 118 is movably mounted, deriving its motion from the push-in cam 32 'through lthe rock lever 119 pivotally connected with the bracket 120 also adjustable upon the bed .10, a connection-rod 121 hinged to the slide 118 by the stud 122 and the connection block 1233 which is pivot'ally` secured to the lever 119 `by the stud 124. Movement of the lever 119 through the cam 32 imparts a reciprocatory movement to the slide 118 toward and away from the chuck 66. The bracket 120 and rock-lever 119 are provided with a plurality of openings 125 vand 126 respectively so that by removal of the pin 127 and placing the same in any one of the other openings 125 and 126 which are brought into register with each other, the length of stroke of the slide 118 may be varied.

The means for providing` an operative connection. between the connection-block 123 andthe connection-rod 121 consists of a key 128, preferably made of fiber or similar material with a lip on each end to prevent relative endwise movement within the connection-block 123, studs 129 that pass through said block and lcontact with the key 128 at their ends, a spring 130, the opposite ends of which bear against the studs 129, and screw 1L31. The position of the screw 131 determines the tension of the spring 130 upon the key 128 and the pressureof the latter upon the connection-rod 121,A one side of which is flattened, as shown in Figure 7, so that said key has contact with said connection over its entire face. This tension is adjusted so that under normal. conditions the slide 118 will operate, but if perchance the conditions be abnormal, either by a blank being presented in a position other than its correct one, or for any other reason, the key 128 will slip upon the connection-rod 121 and there will be no further movement of ,the push-in mechanism.

The outward position of the slide 118 is a'djustably determined by the screw 132 which is threaded through a stud 133 secured in a lug 173 upon the' slide bracket 117 Threaded in a lug upon the slide 118 is a screw 134 having a button 135 in its outer end held by a pin 136 against endwise movement but Vat the same time permitting the rotation thereof. The check-nut 137 holds the screw 134 in any of its adjustedpositions.

ln operation after the transfer Vslide has carried the blank so that it is in line with the chuck 66, this push-in mechanism begins its operation and the button engages the head of the blank while held between the clip 110 and the finger 112 and pushes the same into the bore ofthe chuck 66 while vstill held by the clip and linger, as above described and while so held the transfer slide 97 is moved in its opposite direction releasing its hold upon the blank. The push-in mechanism however continues its movement until the blank is in its desired relative position, this being determined either by this push-in mechanism or the knockout ypin 70, when utilized as a stop as above described. The blank is now in its correct position and -the chuck grasps it through the movement of the chuck sleeve 45, and the push-in mechanism is withdrawn.

It is desirable, at times, with blanks having a short shank to modify the means for placing and locating the blank in the chuck, by substituting the screw 81 with its plunger 8 4 for the screw 134 in the slide 118 and utilizing the positive stop pin 80. With this modilication the end of the shank is brought up against the head of the knock-out rod 70, and the plunger 84 yields slightly, if necessary, to accommodate the blank in positioning it within the chuck.

With blanks of the type just referred to, that is, those having short shanks and where the weight of the head is greater than that of the shank, they frequently register at the discharge end of the chute 91 in a slightly inclined position, this being illustrated in Figure 16 by the axial line 177. They, however, usually right themselves in the transfer mechanism so that the axis of the blank is substantially parallel with that of the chuck. To eliminate all chance as to the rectication of the position of the blank, I have provided a device that is connected with one of the sides of the chute 91 and is more particularly shown in Figures 15 and 16 of the drawings.

This mechanism is only designed to be used with short shank blanks and is readily detachable from the chute. It consists essentially of a guide block 174 pivotally connected with the chute 91 by the p-intle 175 and having a face 176 thereonthat forms an extension of the inner side of that portion of the chute 91 to which it is attached. This extension holds the blank against tilting by ice CII

the position of the chutecover 178 upon thev outside of the blank head andv the kface of the guide block 174 upon the underside thereof7 as illustrated in Figure 16, in Which position the blank is engaged by the clip 110 contacting With that portion of the shank projecting in rear of the guide block 174.

As the transfer slide 97 carries the blank away from the end of the chute, the guide block 174 moves upon its pivot mounting 175 until it assumes the position shown by dotted lines in Figure 15, and is returned to its down or full line position after the transfer slide has returned for the next succeeding blank.

AS the blank 113 with a short shank, espe* cially Where the Weight of the head exceeds that of theJ shank, passes beyond the end of the chute 91, it cannot tilt but is held in correct alignment With the axis `of the blank holding` means by reason of the extension of the chute 91, the Space through which the blank would move during its tilting action being closed by the guide block 174, Which by reason of its hinged mounting is moved out Aof the Way to permit the blank to pass thereby during the movement of the slide.

Adjustably secured to the bed 10 is a slide base 138 Within which are mounted the tool slides 139 and 140, these moving in an angular direction relatively to the axis of the spindle 58 and to each other. Each of these slides is provided With an adjustable tool holder 141 and 142 Within Which are secured the cutter holders 143 and 144, this latter holder adjustably supporting the cutter 145 for shaving the head of the blank and the former holder, the cutter 146 which, as shown herein, cuts a chip off the underside of the head and that portion of the shank adjacent thereto.

Upon the rock shaft 147 journaled in the blocks 148 secured to the bed 10 are the rock levers 149 and 150, the upper ends being forked to receive the Yblock 151 upon a pin 152 secured in the lugs 153 upon said slides. rIhe forked ends are connected by the caps 154. Also mounted upon the rock shaft 147 adjacent to the levers 149 and 150 are the rock arms 155 and 156, each having a cam roll 157 mounted thereon, the one on the arm 155 projecting into the groove in the cutter cam 29 andthe one on the arm 156 projecting into the groove of the cutter caml 28. The rock lever 149 and rock arm 155 and the rock lever 150 and rock arm 156 are each connected by a shearing pin 158 of suoli size as Will permit the operation of the parts under normal conditions but under abnormal conditions the pin Will be sheared and stop the operation of the parts, Without breakage thereof. The cam rolls 157 are mounted upon studs 159 that project through slots 160 in the rock levers 149 and 150 and move freely therein, thus permitting relative movement of the rock levers `and arms whenV either pin 158 is sheared. The tool slides 139 and 140'are moved toward the spindle 58 against the pressure of springs 161 that are mounted Within the slide base 138 and bear at one end against plates 162 secured against Vsaid slides. Af-

,ter the blank has been placed Within the chuck and the push-in mechanism is entirely Withdrawn, or being Withdrawn as may be the case, the sli'des139 and 140 carrying the cutters 145 and 146 move forwardly toward they axis of the blank, the cutter 145 shaving the head of the blank and the cutter 146 taking a chip off the `underside thereof 'and upon that portion of the blank adjacent thereto, thus synchronously truiiig up the` head and shank of the bolt, after Which the cutters are Withdrawn, the hold of the chuck upon the blank is released and the knockout mechanism ejects the blank from the chuck and it drops into a arranged, to receive it, through an openingv 163 in the bed 10. rl`he Width of the upper end of the rock levers 149 and 150 is considerably less than the space between theglugs 153 to prevent the angular movement of the slides 139 and 14() in relation to each other.v lt is apparent that it is desirable that the relative position of the blank Within Athe receptacle conveniently chuck shall be exactly determined'and that` each succeeding blank shall be yplaced lin exactly this saine position iii order that the y blank to the chuck, inserting and holding it therein is such that this result is definitely obtained.

Minor changes and alterations may bev made Within my invention, aside from those herein suggested and I Would there-fore have it understood that l do not limit myself to the exact construction herein shown and described but claim all that falls fairly Within the spirit and scope of the appended claims.
