AUTOMATIC TAPE-MARKING DEVICE.

Application filed my 1,

This invention relates to improvements in machines for marking tape and the like, such tape to be used as labels for garments, etc.

' Oneobject. of this invention is ,to provide a marking machine with means for feeding thetape to the marking table, the actuation of the parts being so timed that the. feedlng and marking of the tapemaybe carried on as one machine operation.

Furthermore, it is an object of this inven tion' to provide an'operative connection between the marking device and thetape feeding mechanism so that the same sourceof power will serve to actuate the entire organization according to a predetermined cycle of operations.

Further objects of the invention will appear from the following description andv claims when considered togetherwith the accompanying drawings.

Flg. 1 is aside elevation showing my 1mproved device embodied in a power marking machine; Fig. 2 isa detail view taken on line .2-2, Fig. 1; Fig. 3 is a front elevation of a power marking machine embodying my improved device for feeding the tape; and Fig.

4 is a detail view on line 4,4, Fig. 1.

The power marking machine to which the present invention relates is of the same general type as that disclosed in the patent to Canine, 1,063,180, June 3,1913, to which reference is had for a fuller understanding of the present invention. The type disks 1 are supported upon the arm 2 pivotally mounted at 3 upon the bracket or pedestal 4, the arm 2 being moved downwardly and upwardly toward and away from the work supporting table 5 by the same style of mechanism as disclosed in the patent above referred to.

In the present case the tape which is to be marked is indicated by reference numeral 6 and is adapted to be drawn from the supply reel 7 suitably mounted on the bracket arm 8. The tape passes over the idlers 9 and 10, the presser roll 11 being provided for use in conjunction with the idler 9. The presser roll 11 is under tension of the spring indicated at 12. On the other side of the table 5 the tape is adapted to be fed between the rollers 13 and 14, the last named roller exerting tension bymeans of the sprin 15. This spring abuts at its lower end the caring on the roller 14 and is provided at itsupper end with the abutment bar 16 suitably secured acrossthe guide-way of the roller bearing 1922. Serial No. 552,545.

suitable tape-engaging surfaces so as to en 7 sure feeding of the tape by frictional surface'engagement. The roller 13 is fixed upon its driving shaft 18 suitably mounted in bracket arms provided upon the machine frame. The ratchet wheel 19 is also fixed to the shaft 18 and is adapted to be rotated in aclockwise direction as viewed in Fig. 2 of the drawings by means of the pawl 20 pivotally mounted upon the pawl bracket 21 which in turn is freely mounted upon the shaft 18. The spring 22 provided upon the bracket 21 maintains thepawl 20 in engagement with the ratchet. The other end portion of the bracket 21 is provided with the slot 23 which receives-the lower end of a chain 24, the other end of which-isfixed at 25 to the rock arm 2 of the marking device. The spring latch 26 is provided 1 for preventing backward movement of the ratchet. A coil spring 27 is provided upon the sleeve 28 which surrounds the shaft 18, this sleeve being maintained in set position by means of the collar 29 fixed on the shaft 18 with thes'et screw 30. The one end of the spring 27 is fixed to the pawl bracket 21 while the other end bears against the outstanding lug orabutment 31 provided upon the machine frame. g 7

Thus it will be seen that upward movement of the type disks 1 will through the chain connection cause the pawl bracket 21 to rotate ina clockwise direction as viewed in Fig. 2 of the drawings thereby causing rotation of the ratchet in the same direction through engagement of the pawl 20. Such movement. of the ratchet 19 causesrotation of the shaft 18 and the feed roller 13 in the'same direction, that is, counter-clockwise direction as viewed in Fig. 3 of the drawings. Such.

movement of the roller 13 will feed the tape across the face of the table 5 so as to present a predetermined length of tape-to be marked H the marking operation the chain 24 will be come slack and the tension of the spring 27 will cause the bracket 21 with the pawl 20 to move in a reverse direction so as to return the pawl to proper position fora section feeding operation.

Thus it will be seen that I have devised a machine organization in which the raising and lowering movement of the type disks will automatically cause intermittent feeding; of the tape into proper position upon the table support for the marking operation.

What I claim is: p I

In a marking machine, the combination of a work support, means adapted when actuated to move toward and fromsaid support for marking the work thereon, means for actuating said marking means, means adapted when actuated to move the work across said support including a pair, of Co-operating rollers .one of which is fast upon a shaft, a-

ratchet wheel also fast upon said shaft, a bracket loosely mounted upon said shaft, a pawl carried by said bracket and co-operating with said ratchet wheel, andconnecting mechanism between said bracket and'said marking means, whereby the actuation of said marking means effects the movement of said bracket and through said pawl and ratchet mechanism effects rotary movement of said shaft and the feeding roller mounted thereon, and spring means mounted upon said RICHARD SGHRAMM.
