This frame is adjustably supported on base 73.

8 is the driven cam shaft having a sprockthe chain 82. 9 is the reciprocating fee carria e carrying the feed jaws.

L o that the details of this device may be the more readily understood, I will first describe it in a very general way. There are I provide the main main and auxilia and auxiliary fee aux1liary\holding\jaws 12 is in spaced relalo iliary feed jaws. 4These holding jaws are tion from the main ijaws 11 to hold a section at the ends of the label strips taut and 1n osition for thereturn 'movement of the auxactuated by cams to o en to permit the feedinv of the strips an to` close to grasp the label strips `during the return movement of the feed jaws.

A series' of shear cutters 13 are provided beyond the main holding jaws and under these cutters the strips of the label are fed preliminary Yto cutting the same by the plurality of shearing blades.

The feed jaws `are carried by the reciprdv eating feed carriage 9 which travels inthe ways 71 before referred to. 15 are the main feed jaws adapted to grasp the projecting ends of the label strips beyond the holding jaws 11 after they have been cut ofi' and then feed the same under the knives for the next cuttin operation. The jaws are shown in the a vanced position in Fig. 4 with the knives raised. The engaging position of the main feed jaws to the ends of the label strips appears in Fig. 8.

16 are the auxiliary feed jaws which reciprocate in the area between the main holdl ing jaws 11 and the` auxiliary fholding jaws 12. The feed jaws, in all instances, as well as the holding jaws, are opened and closed by suitable cams on the cam shaft. When the main jaws engage the end of the label strip as seen in Fig. 8, the auxiliaryfeed jaws 16 close intoengagement with the label strips just in advance of the auxiliary supporting jaws 12. rlfhe holding jaws then' open and the feed carriage advances carrying the feed jaws and the label strips to the next step for thenext cutting operation. When the feed reaches the end of its stroke,

:the holding jaws again close, the knives cut also provided for reciprocating the carriage feed so that the parts operate in definite timed relation to each other.

With this preliminary general descripytion I will describe the various parts, their actuation and relations.

The main holding jaws 11 are supported on a pair of longitudinal supporting rods 17, 18 which serve also to support the stationary blades of the cutting shears, these being supported on end brackets 19, 20, see Fig. 3. The lower jaw member 111 has alongitudinal groovel 112 into which depression the label strips are clamped. A. series ofguide On the frame 7- loops 113 are carried by this lower jaw member'lll so that4 each label strip is separately guided in definite relation `to the said holdmg aws. 114 is thel upper jaw member whic is pivoted to arm 115 by pivot 116. The upper jaw member 114 is provided with a series of ins 114 for separately'engaging each la' el strip. Guardy blade 114 1s disposed in front of the pins 114". This member is rovided 'with an upwardly projecting spring arm 117 to which is connected the tension compression spring 118, which nholds the said upper swinglng jaw 114 into contact with the lower jaw 111. An auxiliary guide loop 119 is secured'to the side of this jaw and it, along with the jaw blade itself, is embraced in the slots of a guide 119 secured to the frame 7. A cam actuated slide21 has a projecting cam arm 210 with a cam 'surf-ace 211 disposed, when reciprocated, to elevate the jaw, 1nember114.

The auxiliary holding jawscomprise the main stationary jaw member 121 which longitudinally grooved'to form a depression lever means 125 which will be described in detail in connection with the auxiliary feed jaws which are actuated in the same way.

These jaws are held yieldingly in closed position by spring 126. A double stop 211 is carried by the cam actuated slide 21 and alternately actuates and trips the lever means `125 to open and close the said holding jaws. The relations of these parts clearly appear in Fig. 4.

The cam slide 21 actuated by cam 22 carried on the cam shaft 8, see Fig. 4i. Cam follower 212 is secured to the slide 21 and the slide is held under tension by tension spring 218, see Fig. 4. rlhe slide 21 and its stops operate to open the main holding jaw and the auxiliary holding jaw at the same time and hold them open while the feed jaws are advancing the label strips and then tripping to close the same when the label strips have been fully advanced.

The feed jaws are secured to and carried by the reciprocating feed carriage 9. The main feed jaws 15 comprise a relatively fixed lower jaw member 151 having a slight depression towards its engaging end. Upper jaw member 152 is provided with spring fingers 153 which are downturned into engaging points, one for each label strip. The upper jaw is carried by pivoted arm`l54 pivoted at 155 in cheek piece 156 and the jawI is held yieldingly downward by the con'lpression spring 157. Cam 158, with flat end, having downwardly projecting actuating the trip lever 158 is pivoted at 158 to the cheek piece 156 and engages the projectsion spring 157 to close the jaws into `engagement with the ends of the cut off label str1 vs as detailed in Fiv 8.

T e auxiliary feed jaws 16 comprisethe comparatively fixed lower jaw 161 and the movable upper jaw 162 provided witha series of clamp spring fingers 163. The upper jaw is pivoted at 164 between the cheek v is timed to cause the said eed Y168 at each end of the travel.

pieces 165 and the jaws are opened by the cam 166 on the rockshaft 167 actuated by trip lever 168. j

he cam actuated slide 24 is provided with stops 243 and 244 to act upon the trip lever It is shown in the tripped position at the right of Fig. 7 with the labe strips clamped. When the feed 'carriage moves to the left of that ligure the cam lever 168 will contact with the stop 243 and open the jaws. The jaws will remain open until the feed carriage returns and the lever is "again tripped to close the same. f

The stop 243 nis cut away as shown in Fig. 7 to permit the passage of the trip lever 158 so that -it willnonly be acted on by its appropriate stop. It will thus be seen that the lever 158 and the lever 168 are tripped by stops on the cam actuated slide 24 and are operated simultaneously to resp and feed the label stops. The slide 24 1s actuated by cam 10 which reacts upon the cam follower arm 245 as seen in Fi 7 The cam 10 jaws to open and close as described. u

It will be seen that when the feed jaws have carried the label strips forwardasindicated at the right of Fig4, the jaws are then opened at the time of severing the labels and the labels are then discharged. The feed carriage is thon returned to the initial position and the jaws are closed to engave the ends of each of the label; strips as tailed in Fig. 8.

rlhe feed carriage 9 reciprocates in the ways 71 and is operated by a cam mechanism (see Figs. 2 and 6) which is precisely comparable to the mechanism shown for reciprocating the feed jaws in the companion application of George L. Bignell. I make no claim to the details of the mechanism but have used it in my combination. Itcomprises an actuating lever 91 fulcrumed on the frame and connected by link 92 to lu 93 l on the feed carriage 9. Cam 94 on cam s aft 8 actuates rocking cam follower 95 which actuates the rocker 96 whichis connected yby L adjustable pitman 97 to the said lever 91.' The movement of the carriage can be adjusted to a nicc'ty and be accurately controlled by the said cam so that it is timed for operation with the holding and feed jaws 1 heretofore deseribed.` It is possible by the dwell of the cams td secure the timed operations as indicated, as 'will be clear from an inspection of the same..

13, 13,- 13 are a plurality of cut off shears. Each comprises a lower; blade member 131 and an upper pivoted blade member 132 whichsis lpivoted on the pivot 133 and held yieldingly in` cutting engagement by the compression spring 134. Each movable blat e is provided with an actuating lever 135 having a cam follower wheel 136 and is held 1nto engagement with the cam 271 hereafter described by the cam spring 137.

The .upper blade 132 is ribbed at 132 to wipe the severed label ends upward against the guard 114 to insure their projectlon to bc engaged by the main. feed 'aws. A longitudinal cam shaft 27 provide with cams 271 and driven by bevel gear 272 actuates the said upper shear members. These shears act upon the label stri which is held taut between the main fee jaws and the main holding jaws as seen in Fi 4. The labels between the shears readilzyy drop down. The labels at the end tend to remain in the feed jaws after the jaws have been opened. I therefore provide a stripper finger 28 car# ried on the rockshaft 281 actuated by lever 282 by cam 273 on shaft 27, see Fig. 2. Beyond eachof theshears is disposed amendless conveyor 29 deliverin the cut ofi labels, as they are severed, rapidly to one side into any suitable receptacle. 7

I have thus described my improved machine in detail. It will be observed that a plurality of label strips are delivered to the printing press and a group of labels rinted on each strip. The label strips are t ien advanced into the machine and placed in the main holding jaws with their ends project,- ing. The machine is then operated, the main feeding jaws grasp the ends of the 'labels and advance them one step, thereby advancingthe entire label strip a step. The cut off knives The feed carriage then reciprocates, and

the main jaws are brought to position to enj gage ytheV cut off ends ofthe strips. The auxiliary jaws are also passed to the corresponding position on the label strip that is now held taut by the holding aws. The. feed 'aws/ are 'then tripped by the cam) means.

When the feeding jaws have thus engaged the label strips, the holdin 4jaws lare opened, the label strips are again a vanced to the cutllt) ting position, and the cycle of operation is com leted. y n

I iiave shown a cam means in each instance especially adapted to the purpose bht it is clear that a variety of mcansmay be employed by suitable timed connections.

The use of a machine of this kind is of very great advantage. A single'operation of the press in the particular arrangement here shown prints three labels on each of seven label strips, i. e., 2l labels in all. The strip is then advanced to the cuttingposition and the entire 21 labels. are cut at a single stroke. Every strokel of the machine thereafter results in the production of 2l complete labels. The rapidity of action over any hand method is apparent.
