Application December 1, 1932, Serial No. 645,210-
4 Claims. This invention relates to a printing machine of that character in which a continuous strip or web of paper or like material, having strings attached to sections thereof is fed intermittently 5 betweenco-operating printing members substantially as shown and described in United States Patent No. 1,318,108 dated. October '7, 1919.
Thepresent invention is an improvement upon the machine disclosed in the patent referred to,
and has for its object to increase the efficiency of ,the same by avoiding interruptions in the use of the machine and consequent loss in production and time, and further has forits object to avoid injury to parts of the machine in transportation,
assembling, and while in use as will be described.
The invention also has for its object to avoid imperfect printing of the tags or strung sections of the web or strip, as will be described.
These and other features ofv this invention will be pointed out in. the claims at. the end of this specification, 1
f Inn-the accompanying drawings-.-
*Fig. ,1 is a vertical longitudinal section of the improved machine;
Fig. 2,.an end elevation of the machine shown in Fig. 1, lookingtoward the left, the roll from which the tag strip -or web -is taken, being omitted; r Fig. 3,.a plan view of the lower orbed portion of the machine,.the side uprights-of the framework being shown in section; 1 v I f Fig. 4, an enlarged view in elevation of the guide members to be referredrto, and
Fig: 5, across section on the line 5-5, Fig. 1, to illustrate the look for the cover plate.
The printing portion of the machine is and may be substantially the same as in the machine disclosed in the patent referred to and comprises a. stationary platen member a, and a reciprocating member, I) co-operating therewith.
The reciprocating member 1) comprises a chase l5 containing type l6 and secured to a plunger l1 connected with and operated by a path cam in a disk-26 faston a shaft 21 supported by the frameworkof the machine.
The type 85 are inked with printers ink by one or more inking rollers 31 supported by the endless carrier in the form of parallel link chains 34, each of' which passes over a sprocket wheel 35 fast on the shaft 21 and under sprocket wheels 36, 31, whereby the, inking roller 3| on its passage beneath the reciprocating printing member 1; applies ink to the type l6. I
During the passage of the inking roller- 3! under the reciprocating printing member, the latter is held stationary by the path cam 25.
The inking rollers 3| have co-operating with them an ink-distributing disk 40 pivoted toa sup. port 42 and designed to be rotated by suitable lugs or projections, not shown, which are located on one of the link chains so as to rotate the disk 40 when an inking roller is out of contact with the said disk.
The base-frame 29 of the machine is provided with a bed plate 54 of, substantially the construction shown and described in the patent referred to and provided with an opening for the pad on the stationary platenva V The bed plate 54 is provided with a slot or channeLnot shown, for the reception of the loops 52 of string carried by theunprinted strip or web 50, andis further provided with slots, not shown, up through which pass pins '9l for 'feedingthe web 50 to the printing mechanism, as described in the patent referred to,
The feed-pins. .l'l, are. carriedby a plate 90 forming part of the feed mechanism, comprising a carriage-slidably mounted in the base frame 29, and having a lug connected by a link or rod 86 with a crank pin 8'! 'on a disk; 88 fastron a shaft89, which is driven from the cam shaft 21. The feedf pinsSL are raised by a cam 93 on a shaft 94 to engage the strung strip. or web 50, between adjacent sections-byentering notches 92 on opposite sides of the said strip or web. The pin plate 90 islowered to withdraw the pins-9l from the notches 92 by a spring I 04, when the strung strip or web has been fed forward into position to beprinted.
The strip or web 50 with theloops 52 of string is fed from a roll 86,-which for convenience is shown as a plain roll butwhich in practice is provided with theloops 52.
The. strung strip orvweb 50 on its way to the printing mechanism passesunder a cover plate I 30 secured to ,a lever Ml', pivoted to a support I42 fastened to aside of the framework.
The cover plate Mil forms with the bed plate 55 a guideway, and said cover plate, in accordance with'the present invention, is extended beyond the front end of the bed plate and forms a substantially rigid upper guide member 200, which co-operates with a substantially rigid lower guide member-21H, which is made as a bar or plate and Q is fastened to the upper surface of a metal block 282 secured as by screws 293 to the front end of I the framework 29. v
The guidemembers 200, ZOI form a guideway 205 for the, Web or strip .50, which guideway is 5 practically a continuation of the guideway formed the bed plate 54.
by the main portion of the cover plate I40 and The rigid guide members 200, 2M areprovided at the front ends with inclined surfaces 205, 201,
which extends transversely of the members 200, 2!)! from one side to the other and register with.
a each other to form rigid deflecting members for the loops52 of string.
The upper guide member 2lllhas made integral with or secured to its inclined front edge a bar 7 209, preferably provided at its opposite ends with upwardly inclined and rounded portions which faces flush with" the inclined edges "of the guide form noses 210 for facilitating the removal of any strings which ma ylie upon the upper surface of the web or strip 50.
, The lower guidemember 21" has made integral with orrsecured to it a similarbar 2!! having rounded inclined noses 2l3 at its opposite ends.
The bars 209, 2 I 2 are arranged with their front members 209 2-9l'so as to. practically form vertical extensions of said inclined edges and thereby provide theguide members with'auxillarydeflecting members of greater depth than the thick- 'ness' of the inclined front edges of the guide members themselves, which construction afiords a wide surface'for'the loops. to engage andthereby facilitate the deflection of the strings which may extend across nel 215 in the upper guide member 2llll and in the main or body portion of the cover-plate.
, The upper guide member 29 0 is normally positioned with relation to the Iowergulde member 2M to form the gufdeway 205 of adepth substantially equal to the thickness of the tag strip or iii of strings is wound into the form of'a roll; and
web 59. This is effected by the vertical support [42 upon which'rests the lever ll: carrying'the cover plate.
In practice, thejwebiw strung with loops 92 the loops of string frequently extend across and underthe web and adhere to the upper and lower the machine is started in operation.
' surfaces of said strip or web, which is in a damp or moistened conditionto enable it to be wound in the form ofa roll};
The strings are moreor less pressed-into the moistened paper web or strip and areseparated therefrom by the upper and lower guiding mem-. bers as the web or strip is fed forward toward the printing mechanism, 7 1
In the present instance, a partially unwound roll is shown, but in practice av roll of greater diameter than that shown in Fig. I is used when When a freshjor full roll is used, the strip to is led down to the guidewaylfl! and is fed into sai'd guideway on an incline, indicated by the dotted line 220, Fig. 1.
made as herein shown and consists of a bar 22l (see Fig. 5-), mounted to slide in. a guideway located below the lower guide member 2 and formed by a bar 222 secured to the block 2n2zas by a screw 223', the sliding bar 2 2 t being provided with afinger 225 which. projects over the cover the orrstrip toward-the chanplate adjacent the upper guide member 200 so as to be engaged by the cover plate.
A very slight clearance between the finger 225 and the cover'plate' I is provided in order'to permit the bar 22! to be manually moved to withdraw the locking finger 225 from above the cover plate,'in case the operator desires to lift the cover plate to gain access to the strip or web beneath the same.- The sliding bar 22L is made sufficiently long to provide a handle 22'! to be grasped by the operator when he desires 1 to unlock the cover plate;
The sliding bar 22I is automatically moved into its operative position by a spring 228 aifixedto the block 202 at its lower end and hav ing its-upper end engaged with a pin 229 projecting from the sliding bar 22I (see Fig. 4).
" The movement of the sliding bar 22I in opposite directions is limited by a pin 239 on the block or bar 222, which pin engages the end walls of a notch 22 in the sliding bar 22! (see Fig; 5). i g
; It will be observed that the locking device for the coverplate prevents the upper guide member 290 being lifted by the tag strip or web 59, and thereby prevents the guideway 295- between the guide members 290, 291 beingen larged sufficiently "to allow'thetag' strip with a string or loop lying thereon to enter the guideway and be carried to the printing mechanism and be printed upon by the latter andthereby produce a tag with imperfect printing thereon.
Provision is made ior enabling the strung strip orweb 59 to be passed through the guideway' 295 and then under the cover plate with the latter in its lowered or operative position, with assurance that the notches 92 in the web or strip are properly positioned with relation to the feed mechanism so :as to enable the feed-pins 9' of the said mechanism whenel'evated'bythe 93, to enter the notches 92 in the strip or web;
For this purpose, the cover plate is provided with an opening 210 (see Fig. 3) which'uncovers a notch 92 in one edge of the "web or strip 50,
and which opening is'located in the cover. plate,
with respect to the feed pins9i so as to'ensure' that the feed pins when elevated will enter notches 92 in the portion of the web or strip which is covered by the cover plate, and which notches are not visible to the operator witt' 'outv lifting the cover plate so asto uncover the same, as' isrequired' in the machine disclosed in the patent above referred to.
By reference to Fig. 3, it win be ebeerved that a notch 92 in the rear edgeof the web orstrlp II is visible to the operator through the opening 2 in therear edge of the coverfplategand when this occurs, the operator is assured that the web or strip fed by hand into the machine through the guideway 295is properly; placed. so
as to be: fed toward the printing mechanism by' the feed pins9l. V g
.The opening :240 in the cover plate avoids thenecessity of theope'ratorraising the cover plate and also avoids the necessity of the feed rice pins 9i being raised in order to positionthe notches in the web or stripil) with relation to the feed-pins9l. These operations, require time and occasion economic loss to theuser of the machine. 7' is l After a' tag. or section 0f the strung strip has been printed, it is cut fromthe, continuous strip or web 59in the manner described in thepatent referred to.
it From the, above description, it will be ob- 2,001,520 served that the upper and lower guide members are of rigid construction and therefore are not liable to be bent or deranged by blows or jars, thereby avoiding delays in the use of the machine and the expense of repairs.
It will also be observed that imperfect work and also loss of time in threading the strung strip or web 50 into the machine is avoided by the lock for the cover plate, which ensures the upper guide member attached to the cover plate being maintained in proper relation to the lower guide member to form a guideway of the proper depth to permit the web or strip 50 to pass into the guideway and exclude the loops 52 of string, which are deflected toward the channels in the cover plate and bed plate by the rigid deflecting members.
This application is a continuation in part of application Serial Number 574,101 filed by me November 10, 1931, and which has matured into Patent No. 1,931,284, dated October 17, 1933.
