HENRY L. SMITH, OF W'A'IEBBURY, CONNECTICUT, ASSIG-NOR TO THE E. J. MANVILLE MACHINE COMPANY, OF WATERBUBY, CONNECTICUT, A CORPORATION OF CON- FEED MECHANISM FOR HEADING IVIACHINES.
. Application filed July 16,
To all whom it may concern: I
Be it known that I, HENRY L. SMITH, a citizen of the United States, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Feed Mechanism for Heading Machines, of which the following is a specification.
This invention relates to those mechanisms which are provided for feeding blanks to metal heading machines of the class shown in United States patent to Campbell No. 926,170, June 29, 1909. In these machines the blanks are fed into dies located in a die pocket formed in the forward end of the frame and are acted upon by a punch or punches which swage or bend the blanks held by the dies to the desired shape. In such machines particularly in those of large size, the dies and die holders are heavy; they require accurate adjustment; and they of course must be changed for different sizes and forms of work, consequently 1t is advantageous to have the dies and their holders readily accessible and easily placed in or removed from the pockets.
The object of the present invention is to construct and arrange a blank feeding mechanism for machines of this character which will feed the blanks surely and accurately and which can be quickly manipulated into feeding position or from feeding position so as to expose the die pocket and permit free insertion, adjustment and removal of the dies and die holders.
The invention is represented as embodied vstructed and arranged according to the invention, swung from over the diepocket in the frame of a heading machine. Fig. 2, on
larger scale, shows a plan with the mechanism swung into operative position overthe dle pocketof the heading machine. Fig. 3
1921. Serial No. 485,369.
is a side elevation of the feed mechanism in dotted line 8-8 on'Fig. 3; Fig. 9 is a vertical section through the blank feed track on the plane indicatedby the dotted line 9-9 on Fig. 3. The frame 1 of these machines is usually a large, heavy and firm casting with a die pocket 2 at the forward end of the frame. In these machines the dies may be arranged on the die bed 3 at the bottom of the pocket or may besupported so as to be carried over the die bed as are the dies 4. The particular form of die pocket and the special shape of the dies is not material to this, invention which is concerned only with the arrangement of the mechanism for feeding the blanks to the dies in the pocket. i
The blank feeding mechanism is mounted on a carriage 5 that is pivotally held on the top of the forward end of the machine frame by a screw stud 6 which is passed through the carriage from above and is threaded into the frame in front of and at one side of the die pocket. This allows the carriage with the feeding mechanism to be swung clear of thedie pocket, as shown in Fig. 1, or tobe swung over thedie pocket, as shown in Fig. 2 in which latter position it is fastened to the top of the frame by screw bolts 7.1
L-shaped track bars 8 areflo cated on an I incline the required distance apart-on the top of the carriage, being fastened at their upper ends to thewall 9 of the carriage, and fastened at their lower ends to a bar. 10 which is attached 'to the carriage. upper ends of the track bars is the'hopper which is designed to receive the blanks 11.'
On the The particular form of hopper is not essential to the invention but that shown comprises two'sections 12, the bottom walls13 of which slope downward and at the back are open to permit theblanks to roll down and drop throu h the opening onto the inclined tracks. (druidei bars 14 are secured to the track bars so aS Q retain the'blanks as lo i'ivard end of the carriage.
they roll down on the track bars which not only support the blanks, but prevents endwise movement of the blanks.
Movable back and forth in ways on the carriage under the lower end of the feed track, is a transverse slide 15. ()n the end of the transverse slide next/to the die pocket is a bar 16 with upwardly extending grooved blocks 17 for receiving the blanks as they roll down the track and carrying them over the die pocket. At the ends of the bar which extends transversely of the slide are upwardly standing guide plates 18 that lo :ate the blocks lengthwise in the carrier (Fig. e). Back of the blank carrier blocks on the slide is a plate 19 that closes the lower end of the track at times during the movements of the transfer slide except when the blank carrier blocks are under the end of the track 5). On the top of the slide is a lug 20 provided with a screw 21 that is adapted to engage 5 lug 22 ,on the carriage for stop ping the slide in exact forward position (Fig. 6). The slide is reciprocated by means of a lever 23 that is pivoted on the pivotal stud 6 of the carriage. This lever is adapt ed to be oscillated by a cam reciprocated rod 24:.(Fig. 2) for drawing back the slide into position for the carrier to receive a blank and then carrying the slide and blank forward over the die pocket.
A bracket 25 is fastened vertically to the Movable up and down in guide ways formed in this bracket is a slide 26. A link 27 connects the slide with the end of a rocker arm 28 secured to one end of a rock shaft 29 mounted in a bearing bracket '30 fastened to the top of the carriage (Fig. 3). On the other end of the rock shaft is a lever 31 which is designed to be oscillated by the cam reciprocated rod 32 (Fig. 2). The downward limit of the slide determined by the screw33 that is threaded into a lug :34- at the upper face at the middle the block is a finger the fingers 38 preferably being rigid and the finger 39 being yielding 5). A ring .40 connected between the block and the slide tends to draw the lower ends of the fingers forward. Av stop lug- 41 at the top ofthe bloc-k engages the lower end of the slide and limits the amount of forward movement of the lower end the fingers und r h p lwo he spring e- Wh t is eed is a a h d t t e m ehin w t ieh t is to be used; th an fer s ide 15 seat ba k a d rece ves a b ank then 1 8 forward and stops with the blank beneath the raised fingers carried by the vertical slide 26 (Fig. l); The lingers then come down and grasp and. pick up the blank and after the transfer slide is drawn back out of the way, the lingers move down and deposit the blank in the dies below (Fig. Then the fingers are raised out of the way, the cams of the machine being timed to perform these operations in the proper time.
To prevent more than one blank at a time from rolling from the track, a gate .2 is arranged at the lower end of the track 5). This gate is fastened to a slide li} designed to be moved vertically in a way in the lower end of the bracket 25 the slide being retained in position byplates -l&' and 45 (Figs. 6. 7 and 8). The lower end of a link l6 is pivoted to the gate slide and the upper end of the link is loosely connected with a lever 47, a pin &8 on the lever passingthrough a slot 4 9 in the link (Fig. 5). A spring connected between the pin 4-8 and the link pin 51 projected from the slide, normally holds the pin 48 at the lower end of the slot.
4:9 and a spring 52 connected between the pin 48 and a pin 53 projecting from the fixed plate 44; tends to pull down the gate and turn the free end of the lever 45? into the path of a cam block adjust-ably fastened to the linger slide 26 (Figs. 5 and 6). \Yhen the linger slide goes down and the transfer slide is forward, the cam 5d engages the le ver and looks it so that the spring 50' lifts the gate from in front of the lower end of the track. lVhen the linger slide is raised so as to release the lever and the transfer slide is drawn back, the spring 52 pulls the gate down in front of the lower end of the track and cuts off all but the lowest blank and pushes that blank into the carrier block on the transfer slide. In order to lock the gate down and prevent the feeding of any of the blanks while the machine in operation, a bolt 55 n'iounted to move horizoi'itally in the bracket 26 may be pushed over the top of the slide 43 so as to preventit from rising under the pull. of the spring 50 the lever is swung by the cam 54: 7 and 8). This bolt is engaged by a lever 6 which is connected by a link 57 with the rocker arm 58 on the lower end of a rock shaft 59. the upper end of which is provided with a hand lever 60 (Fig. 2).
lYith this mechanism the machine may be run for adjusting and testing without feeding any of the blanks by turning thehand lever 60 and locking down the gate. lVhen the gate is raised the blanks will be fed one at a time into the transfer slide and carried into line with the fingers which will pick up the blank and then carry it down to the dies below, Whenever it is desired to remove and replace the dies and their holders M0 djust he e Pa he i PQQ Q may pocket, and an inclined track for receiving blanks, a cut off gate at the lower end of the track, means for locking said gate over the end of the track and transfer mechanism for removing blanks from the track,
mounted on and movable with the carriage toward and from the die pocket.
2. The combination with a metal heading machine of a carriage pivotally mounted on the machine frame adjacent to the die pocket, and an inclined track for receiving blanks, a cut off at the'lower end of the track, a horizontally movable blank carrier for removing blanks from the track and a vertically movable blank carrier for removing blanks from the horizontally movable carrier, mounted on and movable with the carriage toward and from the die pocket.
7 3. The combination with a metal heading machine of a carriage pivotally mounted on the machine frame adjacent to the die pocket whereby the carriage may be swung over or away from the die pocket, said carriage supporting a blank receptacle, an inclined track leading from the receptable, a horizontally movable blank carrier at the lower endof the track and a vertically movable blank carrier for removing blanks from the horizontally moving carrier.
