WHEELER, WEST MYSTIC, CONIIEGTIGUT, ASSIGNOR TO THE STANDARD MACHINERY 00., OF MYSTIC, COlil'llIElC."tlEGl'Ill A CORPORATION FEED MECHANISM FOR- EMBOSSING PRESSEES AND THE LIKE Application filed June 13 1923. Serial No. 235,149.
This invention relates to an improvement in feed-mechanisms for embossin presses and the like and particularly to feec -mechanisms of the pusher type.
In the process of embossing or impressing book-covers and the like it is often necessary for well-understood reasons, to run a given cover or other blank through a press two or more times. One of the main problems has been to feed the blank to exactly the same position each time it is introduced into the same or a different machine.
The object of this invention is to produce a reliable and effective feed-mechanism constructed with particular reference to securing the accurate registration of the blanks to be embossed or otherwise impressed.
WVith this object in view my invention consists in a feed-mechanism'having certain de tails of construction and combinations of parts as will be hereinafter described and particularly recited in the claims.
In the accompanying drawings:
Fig. 1 is a broken schematic view in side elevation of an embossing press equipped with my improved feed-mechanism;
Fig. 2 is a horizontal sectional view thereof taken on the line 22 of Fig. 1;
Fig. 3 is a vertical sectional view taken on the line 3-3 of Fig. 2 but showing the parts in the positions due to them just after the delivery-fingers have completed their task of moving the book-cover blank forward onto the press-bed;
Fig. 4: is a view corresponding to Fig. 3 but showing the parts in the positions due to them after the bed has been moved upward to cause the pusher-fingers to finally position the blank beneath the embossing-die;
Fig. 5 is an enlarged-scale broken sectional view on the line 55 of Fig. 2; and
Fig. 6 is a corresponding view on the line 66 of Fig 2.
The embossing press herein chosen for the illustration of my invention consists of an upper press-member or head 10 mounted upon the upper ends of four vertically-arranged tie-r0ds 11 upon which is mounted for vertical reciprocation a complementary press-member or bed 12 which may be moved toward and away from the head 10 by any of the well-known mechanisms employed in embossing presses and requiring no illustration herein.
The bed 12 has projecting from its rear face near the opposite sides thereof a pair of complementary brackets 13, each of which is grooved for the reception and guidance of one of a pair of corresponding reciprocating rack-bars 14 having its under face formed with teeth 15 meshed into by a driving-pinion 16 mounted upon a transverseshaft 17 periodically driven from any convenient source to advance and retire the rack bars 14 as will hereinafter appear.
Each of the two rack-bars ll above described is provided with an inwardly-projecting arm 18 which mounts a pair of downwardly-yielding spring-like delivery-fingers 19, the forward end of each of which is downwardly offset to form a shoulder 20 which. together with the corresponding shoulders of the other delivery-fingers, is adapted to engage the rear edge of the lowermost book-cover 21 of a stack of covers 22 resting upon the brackets 13 and positioned between two complementary L-shaped guides 23., the lower edge 24 of the front-wall of which is spaced above the surface of the brackets 13 a distance substantially corresponding to the thickness of one of the bookcovers.
When the transverse-shaft l'? is actuated from any suitable source the rack-bars 14: will be moved forward toward the bed 12 and the respective shoulders 20 of the deliveryfingers 19 carried thereby will engage the lowermost cover 21 of the stack 22 and move the same forward onto the upper face of the bed 12 a distance sufficiently far onto the bed 12 to permit a pair of complementary pivotal pusher-fingers to drop down by gravity back of the rear edge of the said bookface of the said bed 12 on opposite sides of the path of travel of the book-cover.
Positioned so as to have its rounded outer end project into the guide-groove 26 of the plate 29 is an abutment-pin 31 against which the adjacent side edge of the book-cover is forced by a series of bowed springs 32 mounted in the groove 27 of the oppositelylocated complementary guide-plate 30.
The pusher-fingers above mentioned are ivotally mounted upon pins 33 extending between ears 34 offsetting from a transversely-arranged pusher-bar 35, the respective opposite ends of which are guided for reciprocating movement in the slots 36 of fixtures 37 secured to the bed 12 near the opposite side edges thereof. The extreme outer ends of the said pusher-bar are formed with cylindricalterminals 38, each of which is entered into a cam-slot 39, one of which is formed in secured four upwardly-bowedspring-fingers 44 which are adapted to bear upon the upper face of a previously-impressed blank as the same is pushed across the :u-pper face of the j fingers 25.
bed 12 by an on-coming fresh blank being positioned by the pusher-fingers 25, so that the rearedge of the new blank is firmly held against the front edge of the said pusherfingers by the resistance offered :to the movement of'the previously-impressed blank by thespring-fingers 44. v I
In the operation of my improved feedmechanism the-turning of the shaft 17 in the direction indicated by the arrow in Fig. 1 will eause'the rack-bars 14 to move inward toward the bed 12, with the effect of causing the .delivery-fingers 19 to pick out the lowermost blank 21 from the pile 22 and move the same from the position in which it is shown in Fig. 1 to the position in which it is shown in Fig.
'3, in which position its rear edge is just forward of the forward faces of the pusher- During the initial forwarding movement of the said blank, the pusherfingers swing upward upon their pivots 33 and ride upon the upper face of the blank until, as above described, the said blank has been moved sufiiciently far to permit them to drop by gravity back of its rear edge.
. The raclnbars 14 now retire and the bed 12 is moved upward by any suitable mechanism which causes the pusher-fingers 25 to advance the blank 21 centrally beneath a die 45 carried by the head 10. This advance movementof the pusher-fingers during the rising movement of the bed 12 is effected by the inclined-reaches 41 of the plate-like cams 40 into which the cylindrical terminals of the said pusher-bar are entered. The inclinedreaches 41 are so proportioned as to complete the positioning of the blank under the die 45 just before the latter makes contact with the blank. During the continued upward movement of the bed 12 to force the blank into engagement with the die 45, the cylindrical terminals 38 of the pusher-bar 35 ride idly in the vertical reaches 42 of the respective slots 39.
During the operation of advancing the new and unimpressed blank by means of the pusher-fingers 25 as just above described, the new blank forces a previously-impressed blank forward upon the bed 12 and beneath the spring-fingers 44, so that the blank now being positioned is maintained against the forward faces of the pusherdinqers 25 and prevented from beingcanted or kicked clear by the rapid movement of the said fingers. Meanwhile, also, the bowed springs 32 in the groove 27 of the guide-plate 30 act to maintain the left-hand edge of the new blank in engagement with the abutment-pin 31.
As soon as the blank has been impressed, the bed 12 retires downward and the cam-slots 39 of the respective cams 40 act to retire the pusher-bar 35, together with its fingers 25, into the position in which the parts are shown in Figs. 1, 2 and 3.
From the foregoing it will be seen that the blank throughout its final positioning beneath the die 45 will on one hand be firmly held in engagement with both of the pusherfingers 25 by the resistance offered by the spring-fingers 44 and, on the other hand, its side edge will be held in contact with the abutment-pin 31 by the bowed springs 32.
By means of a feed-mechanism above described, I am enabled to run the blanks through the embossing press, ,or through a11- other machine having three points of contact for the edge of the blank, and secure each time the exact positioning of the blank required for properly locating the successive impressions with respect to each other.
