Application led January 10, 1924. Serial No. 685,325.

To all 'whom it ma concern:

Be it known that I, FRANK M. PIERCE, a citizen of the United States, and a resident of Chicago, county of Cook, State of Illinois, have invented certain new and useful Im rovements in VVrapp-ing Machines, of which the followin is a specification.

This invention re ates to machines for use in Wrapping annular objectsxsu'ch as automobile tires, coils of wire, or similar articles, with a spirally applied wrapping` such, for example, as a paper Wrapping. The invention relates to machines of the type shown in my prior Patent No. 1,399,939 dated December 13, 1921, and is for an improvement thereon, by means of which the machine therein shown may be operated more rapidly and economically.

The machine shown herein is of the type wherein the article to be wrapped is supported and rotated by positively driven feed rollers within the path of a rapidly revolving ring shuttle which passes through the central opening of the rotating article, the shuttle carrying the paper or other material which is thereby wrapped about the article. This type of machine is generally well known. The shuttle is carried in a shuttle frame and both the shuttle and the frame are provided with openings through which the article may be placed in .position and removed when the wrapping is completed, the openings for this purpose being in' registry. The present invention has for its ob ject the provision of mechanism whereby the shuttle is automatically stopped with its opening or gap in registry with the opening or gap in the shuttle supporting frame This mechanism is in combination with the devices which disengage the rotating parts of the machine from its drive so that the stoppage of the shuttle and the other elements of the machine occur simultaneously.

In the drawings: t Figure 1 is a side elevation of the Wrapping machine having my improvement applied thereto;

Figure 2 is a plan View partially 1n section 0n the line 2 2 of Figure l;

Figure 3 is a vertical section on the line 3 3 of Figure 2; and

Figure 4 is a detail of the lever mechanism for the shuttle brake, the view being taken on the line 4 4 of Figure 1.

It will be understood that the machine herein shown is in its principal operative features similar to that shown in my prior patent above referred to and it is therefore unnecessary to describe the details of the machine except in so far as they relate to the specific improvements to be covered herein.

The machine comprises a base 1, at one side of which is arranged a support 2 for the operating motor 3, the pinion 4 of which engages a gear 5 which carries a clutch 6, both being rotatable upon the main driving shaft 7. The clutch is operated to connect it to the driving shaft by means of a shifting 'lever 8 pivoted to the base of the machine at 9 and connected at its upper end to a lilik 10 which is, in turn` secured to a control shaft l2 mounted in suitable bearings 13 on the machine frame. The forward end of the shaft is provided with a hand lever 14 and, if desired, foot treadles 15 may also be incorporated in the machine, these treadles being connected to a cross bar 16 secured to the shaft 12 at any convenient point. By the operation of the lever let or foot treadles 15, the machine may he stopped or started as desired. p

In the frame of the machine are mounted the adjustable supporting rollers or drums 16, which are concave or flanged as desired, and are intende-d to support and drive the object to be wrapped, herein shown at 17. The means for adjusting the rollers to accommodate various sizes of articles need not be described herein, nor will the means for driving one or both of them, as neither of these features form any part of the present invention, it being sulicient merely to state vtrack or raceway 21. The shuttle carrier shuttle 'is substantia lyring shaped ,asl

shown, bein broken'away to ,permit the insel-tion of t e article, the parts belngpositioned in Figure2 so that the article may be insertedv or removed. The shuttlek carries upon its upper surfacea pinor, )spool 25 upon which ytheroll ofgwra p1ng1ma terial 26 is supporte'd,fthefmaterial passing from the s oolover a tension device 27, through a older 28 andover a. 29 to the article. l u

The shuttle is'driven from a pulley 30 on the main shaft by a belt 31. The belt is guided by a series of pulleys, indicated by the numerals 32, so that it passes 'from the pulley 30 to the top plate of the machlne and then in a horizontal plane around two v sides of the shuttle, being received in a groove 33 in the outer periphery thereof and back.

to the pulley 30. A At one point on the outer periphery of the shuttle is formed an enlargement o r projection 34, which, in this form of the invention and as shown in Figure 2, is in the form of a cam or curved lug which is preferably formed as an eccentric curved surface projecting outwardly. from the outer surface of the shuttle. On the upper surface of the top plate 18 is pivoted a lever 35, the free end of which is provided with a brake shoe 36 adapted to contact with the cam 34 and 1s so located so that when the lever is rocked about its pivot toward the shuttle, the latter will be stopped with its gap in line with the gap in the shuttle frame. The rear end of the lever is provided with a series of holes 37 for major adjustn'ient purposes, in which is .received one end of an angular pin 38 which is adjustably received in a pivoted fork 39 so that minor adjustments may be made (Figure 4) The fork 39 is pivoted to a small bell crank 40 which is 'in 'turn connected to the upper end of a link 41 which at its lower end 1s pivotally 'connected to a arm 42 carried upon the shaft 12.

By the mechanism which has been described, it will be seen that as the shaft 12 is rocked toward the left, as shown in Fig. ure 1, the clutch 6 will be released andthe brake 34 will be brought into position to engage the projection 36 as the shuttle revolves, and the shuttle will be stopped with its parts in position so that the object can be removed. Should the lever be operated just as the cam is passing the brake, it will continue its revolution and be caught and held when these parts are again brought into cooperation.

aimsfto provide a positive stop for the shuttle""vc"ithA the gap or shuttle opening in line with `the. corres ondin gap 1n the shuttle frame., .It may u e use 'in all types of wrappin `,machines oft-his general desi and wit ip open gap shuttles or those whlch are provided with swinging or removable gates. .The action of the attachment is quick and positive and will save time in the operation of the machine.

Changes and modifications other than those suggestedmay be made in the design of the machine within the scope of the claims appended hereto.`
