'sEAM'IN'G MECHANISM.

Tv aZZ aha-m it 'concem:

Be it kne i'ifn that I, JOSEPH P'EYsn'R, a cit-iteh of the United States, and a resident of Mouiit VernOn, in the County f West chestei and State of New Yerk have invented certain new and useful Improvements in seamin Mechanism, of Which the following is a speei-ficatien.

This inventien relates to seaming mechanism fer seaming the eeveis On centain'eifs 'Of sheet iiiat'elihl aid has fi its iiiaiii Objest and feats-re the pie-auction "of simple, effective and high speed means for doubleseaming square 01'' iife giilar-sheped cahs.

In the accompanying drawings the inventibn is disclosed in a dehbfete and prefefied fOfin in fvhi'eh Fig. 1 is a vertical sectional View "oil the 'plafi'e Of line 1'1 f Fig. 2 thi'Ough a sean'ief heard embedying my inventiehi Fig. 2 is a horizontal sectional view on the plane at 11116 5P2 Of Fig. 1.

Fig. 3 is a Vertical sectional View On the plane Of line 83 Of Fig: 1. a 1

Fig; 4 is a hOrizOht'al sectional View On the plane of his 4- -4 Of Fig. 1*.

In devices for 'seaihihg squaie Oiirregular shapes containers it Will he understood that the seeming; tOOls, in addition to the normal in-andjlit movement to per'fofin the seaming qpeiatioii, must also receive a sieveiiint following the Varying shape Of the cOiitainer'; If the ee 'i'ainer shiiip enguhii surfaees, s is frequently the case, diific-ulty' is encountered iii obtaining a high speed because Of the short angular miss that iiiiist be iii-able the fll'i' e-ii gaging the felle msm. I In ofderto Obtain a less pronounced angiilaiity (if the followand thereby making it possible tO-ni'ove the parts at a higher 'speed, I employs follow-cam the shape Of which is coinpleinfitafy te' that Of the shape Of the irreguiai s'he' e container. This 'fcilloii c'am Ih-Bffablj gentmls seveiai seaming t'o'ijls and is mounted so as tO have its centi' f rotation coincident with the center Of the chuck and concent ic Withthe saming cam thereby producing a compact struture capable of high speed and adequate lubrication;

Seaming machines are divided into two classes, Vii, these hich the container to be seamed rotates and the seeming tools are relatively stationary', and these in which the c'Ont-ainef is at rest during the seaming Operatioii and the seaming tOe'ls travel in an Orbit a On'nd the container. This inventiqn is applicable to both of these fo l-ins. If the c'Ontainei' fb'tat'es, then Obviously the "fellow-cam must rotate at the same speed, but when, as in the pi'esent instaii-ce the container stands still the foll'OW-cahiiike- Wise stands still.

Referring 't'othe pa-i'ticulai" io'i' ni in Which i the invention is here emhcdi'd 1 indie-cites a chuck, here shown statidnary, which is the eempisiiieiiiii member of the iisiiiii pedestal (not shown). 2 is the seainei head carrying the tOOls 4 is the fbll'ovv cam eOnvenieiitly mounted on the'chuck 18 indicates the and 5 is the seamer cani. shape Of the container to be seamed. In the present instance where the chuek is statienary the seaming head is given a nuIn bef of revolutions; say sixteen, fer each seaming 'op'r'atieh by means Well known in the art and not shdv'vn and the s'eaining' eain 1s gi en a different ndinhei Of ivbliltions, say fifteen, so tO produce a net difl'eienc'e of one fevOhitiOh between the seaming tools and the seainer' cam in a manner Well understOO'd to Obtain the same result as iivculd he Obtained if the cOntainer were ietating and the seaniingteol's were relatively stationary.

The seeming tOOls afe iii the pfes'ent ihstance carried by slides 6 which have 'a i'e'cipi'e c'ating ino'iieme'nt in the Silll' f head. Any suitable niea'nsinay he empieyed to impart the combined motion produced by the follow-cam and the v'seamei" cant said slides and therefdr'e to the te'ol's, although the particular means here disclosed e'oiisti- 't'ute in themselves valuable featiii'es oi t i'e invention. As heie shown a fOileii -Oain lever 7 is pivotally supported at 8 "(hi the seanier head and has a cam foil 9 engaging fOlIOW Oain 4; and pivetalli inount'd on the follow-Cain lever is a seam'ei' Cain lever 110 in the shape of a bell crank having a gia-in r611 11 engaging seai n'ei" caiii its \i'ill he noted the Center of Oath r011 11 substantially cbincideht 01 in line with the c'eht'er Of pivdt 8 so that the i'dcliiii'g iilfi jfl tiii'ieiit 6f Cain lever 7 Will net Vai'y the posit'ioii O chin roller 11 iii em 5. Pivot-any hipp e-ted at its central peiht, On that end Of felloiii-cah'l iei eiwhich is oppesiie to the point where cam foil 9 is lOc ated, is a IOekiiig lever 12, one end of Which is pivotally- OOnne'cted to seainer' cam lever 10 by means-sf link 13; and the other end of Which is pii 'ota'lly cenn'ected to slide 6 by means Of link 14. It has been noted above that cam roll 11 is substantially coincident with pivot S. In de tail the arrangement is as follows: One of the seaming tools 3 is a first-operation roller and the other the second operation roller. When cam 5 moves cam roller 11 of the second operation roller to cause the latter to finish the seam, the centers of 11 and 8 are practically in line with each other because it is necessary during the finishing operation to follow the exact contour of the container, but since cam roller 11 of the first operation seaming tool travels in the same cam groove 5 as roller 11 of the second operation seaming tool, it will be understood that it must be slightly oft-center with respect to 5w when the first operation seaming roller is in its innermost position because the first operation seaming roller must not move as far inwardly as the second operation seaming roller. From this it will be understood that slide 6 is controlled by the combined motion of the two cams, the follow-cam causing its cam lever to move in accordance with the shape of the container and the seamer cam causing the requisite in and out movement of the seaming tools during the seaming operation. As shown, there is a system of levers for each seaming tool, and both lever systems are actuated by the same cams.

In order to enable the operator to adjust the seaming tools to different sizes of containers the following expedient is provided: Slide 6 is provided with a slidable carrier 15 which mounts the seaming roller. Sliding movement of this carrier with relation to 6 is effected by threaded member 16 in threaded engagement with said carrier and rotatably and idly engz-iging slide 6. Bolt and nut 17 are used to clamp the parts together when proper adjustment has been made.
