APPARATUS FOR PACKAGING SAFETY PINS Filed Nov. 25, 1944 Patented May 4, 1948 OFF CE Wis, assignor to Inter Products Company, Chia corporation of Delaware Application November 23, 1944, Serial No. 564,863

This invention. relates V a method and apparatus for making the same, and theprincipal objects of the invention are to provide a very inexpensive but secure package for a limited and predetermined number of safety pins;

to provide a method by which the improved package may be rapidly and economically made; and to provide apparatus for automatically producing the package at a high rate of speed. Another object is to provide a machineof the character indicated which will be dependable in operation and will require but little, if any, attention by an operator. i

Other objects and advantages of the invention will be understood by reference to the following specification and accompanying drawing (one sheet) wherein there is illustrated a package em.- bodying a selected form of the invention together with the method and a selected apparatus for practicing the method and making the package.

In the drawin l i Fig. 1 is a perspective illustrating one form of package embodying the invention;

Fig. 2 is a perspective illustrating a, strip produced by the method and apparatus about to be described, and from which strip, packages such as shown in Fig. 1 are out; i it i Fig. 3 is a side elevation of apparatus for practicing the method and producing the improved package, certain portions being broken away and shown in section to better illustrate the construction, and V l Fig. 4 is a section on the line 4-4 of Fig. 3.

The package embodies two paper or other sheet material plies I and 2 between which are located a pair of safety pins .3. Oneof the tape strips, such as the tape strip 2, may be made of adhesive tape; that is, tape having one face coated with glue which serves to adhesively unite the two plies with the safety pins therebetween.

A package such as above described may initially beformed in along strip, such as shown in Fig. 2, from which predetermined lengths may be cut to form packages having two pins or any multiple thereof. e 1

e Th pparatus for forming the packag es" comprises a table 4 above whichthere ismounted an endless conveyor 5 which carries a seriesof flights or pusher fingers 6 in regularly spaced relation, thespacing being suflicient to receive: between the flights somewhat more than the length .of the pins to be packaged. The conveyor 5 is mounted centrally of the tablet so that portions of the table extend laterally from the opposite sides of the conveyor as best, shown in Fig. 4.

Binsmay bedelivered in pairs by pin-making machinery to 'thechannel 8 on opposite sides of the partition lsojas to be positioned in pairs in front of the succeeding pairs of flights 6 or pins may be deposited in bulk on the table 4 on opposite sides of the channel 8 and manually fed one'by one into the spaces between the flights 6 on opposite sides of the partition 1.

The conveyor'5 is continuously drivenby means of an electric motor I ll'which drives a speed reducing unit I l havingan output. shaft l2 to which there is secured a sprocket l3. A chain l4 en gaging the sprocket I3 also engages a sprocket l5 on a suitably. journalledshaft l6 which also carries a sprocket H. A chain lfltransmits power from the sprocket ll'to a sprocket ona shaft l9 which carries a conveyor chain driving sprocket 20. The sprocket 20 engages one reach of the conveyor chain 5 nearthecorner sprocket 2| which cooperates with other sprockets 22, 23and 24 to guide the conveyor chain in a continuous path of traveL, I p v i 0n the shaft Hi there is also mounted a roll 25, the roll being fastto the shaft It so as to be driven thereby. 1 l a A web of adhesive tape 26 is drawn. from a supply roll 2! of such tape through a suitable guide 28 and over a wetting or glue applying roll 29 and thence around the roll. 25 ,and between said roll and an overlying pressure or squeeze roll 30. Another'web of suitable tape-like material 3ljisldrawn from a supply roll 32 under a guide roll 33. through a suitable guide member all. and around the squeeze roll 30 so. as to be squeezed into face toface engagement with the adhesive bearing surfaceof; the tape strip 26. The two tape strips thus, joined in face to face relation are carried forwardly (over a suitably supported guide, ro11 35 and between upper and lower press rolls 35' and 31. respectively. The lower press roll 31 iscontinuously driven by means of "a chain, whichengages a sprocket carried by the driven shaft. I 6 and another suitable sprocket on theshaft of the roll 31.; t

Pairs of safety pins fed forward by the successive flights 6 on the oonveyor chain 5 are fed into a suitable chute 39 which conducts or guides the successive pairs'o'f pins into the nip of the convergingtape strips 26 and 3 I as shown in Fig. 3. The successive pairs ofpins are, of course, deliverejd'in timed relation to each other so that the pairs of pins will be spaced longitudinally from each ot r erilalong the lengths of. the tape strips to therebyproducegthe relationship illustratedinFig, 2].; ute. 39 orat leastits top wallma'yadvantageously be'made of transparentj material;to facilitate inspection of the ficiently resilient material to permit the thic lgness of the safety pin tO beCQIIle embedded in" the rolls during the passage thei eof btwefithe rollsto thereby insure the production of, iace to face contact between the a cut, u'rfa'ce s of the tape strips around the safety, ns, r a
