STAPLING MACHINE Filed April 28, 1928 1 maxi Parser WILLIAM IRVINE, OF PHILADELPHIA, PENNSYLi/ 11A, ASSIGNOR, BY MESH E ASSIGN- MENC'JS, TO HOWARD il-OLE, BEFFIJAMI 0111:, ELIAS VQ/GLF, LU'U'IS WOLF, AND
ALBERT VIOLF, COPAETNERS DOING BUHINIISS AS NATIONAL METAL EDGE BOX COIVIPANY, G1 PHILADELPI-EXA, PENHSYLVANIA STAPLING Application filed April 28,
This invention relates to a guard for a stapling machine and more particularly to that type of machine having a vertically reciprocable fastener inserting means.
In using stapling machines having overhanging heads and work plates therebeneath and vertically reciprocable fastener inserting means, there is considerable danger of an operator, in manipulating the work, getting his hand or fingers beneath the reciprocating means. This is particularly true when the work is of such character as requires the application of some little force to move it properly into or from fastener receiving position below the head.
it is, accordingly, an object of the present invention to provide a guard which ill pre vent the insertion of the hand of the operator beneath the fastening mechanism. A further object is the provision of a guarc which will so act upon the inserted work as to eliminate to a considerable degree the necessity for manipulation by the operator.
In the accompanying drawing:
Fig. 1 is a side elevation, partly in section, of a stapling machine provided with the improved guard.
Fi g. 2 is a front view of the machine.
Fig. 3 is a fragmentary side view showing the work inserted beneath the guard and stapling mechanism.
Fig. l is a plan View of the guard.
Fig. 5 is a fragmentary perspective view of a box blank which the machine is particularly adapted to staple.
The stapling machine disclosed comprises a horizontal arm 2 having a head overhanging the work plate. In the head is mounted for vertical reciprocation fastener inserting means, designated generally by the numeral 4:. This means operates in the ordinary manner to sever from a reel 6 of metallic ribbon, guided through a suitable guideway 8, short sections which are subsequently bent into U form and pressed through the work and clinched below the same by cooperating means under the work plate 10. The fastener inserting means is suitably driven in any ordinary manner, for example, by a motor under the control of the operator.
MA CHEW 1928. Serial No. 273,535.
A rear stop 12 is mounted for adjustment rearwardly in the work plate 10. This stop serves to determine the position of the inserted fasteners relative to the transverse edge the work. If it is desired to place along an edge of the work two staples, suitable side stops 14 and 16 may be provided which, by contacting with the side edges of the work, determine the relative positions of the staples.
A guard 18 is provided with a horizontally extending portion and a vertically extending portion 20, the latter being secured to the head by rivets or screws 22. The guard is suitably cut away at 24 to receive the reciprocating stapling means and the stop 12, the cut-away portion of the guard permitting rearward adjustment of the stop. The forward upturned portion of the guard prev nts the insertion of the operators hand he neath the reciprocating portions of the stamechanism.
The function of the guard in properly holding the work to be stapled will be best understood by reference to Fig. 5, which shows a blank from which a pasteboard box is formed, this blank being indicated generally at 26. The blank includes folded side portions 28 and folded edges 30, one of which is shown. Staples 32 are inserted through the folded ends 30. The main portion of the blank is scored along lines 34 and 36, whereby, when thefolded sides are moved outwardly and the box end is folded along scored line 36, the
several folds defined by scored lines 34 will be secured beneath the folded transverse end 30, thereby forming a rectangular box. If an attempt was made without the guard to insert folded end beneath the stapling mechanism, it was found that the tendency of the folded end to spring outwardly required the operator to hold such end downwardly in proper position below the staple inserting means. Furthermore, the upward springing of these transverse ends necessitated further manipulation to remove the blank from the machine. When the guard is used, the round.- ed junction between the horizontal portion and. the vertical portion tends to fold the porns 80 to retain it in proper condition for the isertior of the staples. The removal is readily acromplished si there are no portions of the mechanism with which the folded end would normally tend to engage. Accordingly, as a result of the provision of the improved guard, the insertion and removal of the wcrl: is facilitated and the danger to the operator is removed.
Having now fully described my invention, what I claim and desire to protect by Letters Patent is:
1. In combination with a fastener inserting mechanism including a Work plate, an overhanging head, and vertically reciprocable fastener inserting means, a gua 7d mounted in spaced relationship with d plate below said head, and a stop adjust-ably moun ed behind said fastener inserting means, said guard being cut away to receive said stop.
2. In combination With a fastener inserting mechanism including a work plate, an overhanging head, and a vertically reciprocahle fastener inserting means, a guard havinr; a portion arranged in substantial parallelism with the work plate and s; aced therefrom for the insertion of Work and eaten on. opposite sides and to the rear of the path of reciprocation of the fastener insertii'ig means, and having a vertical. portion extending upwardly in front of the fastener inserting means from the front end of the first mentioned portion and secured to the overhanging head, and a cooperating stop located rear wardly of the path of reciprocation of the tener inserting means and arranged to e Work inserted rearwardly under the guai In testimony of which invention, 1 have hereunto set my hand, at Philadelphia, Pennsylvania, on this 27th day of April, 1928.
