c. H. PETSKEYES WEB ROLL SUPPORT Filed June 9, 1945 IN V EN TOR.

Patented July 13, 1948 WEB ROLL SUPPORT Charles H. Petskeyes, Davenport, Iowa, assignor to Gellman Manufacturing Company, Rock Island, 111., a corporation of Illinois Application June 9,1945, Serial No. 598,470

1 Claim. (01. 24268) This invention relates to certain novel improvements in web roll supports and more particularly the invention is concerned with and relates to an arrangement for preventing the overriding or backlashing of a roll of paper during the wrapping operation of the machine.

In this aspect of the invention, the primary object is to provide an arrangement capable of these accomplishments, which will be economical in manufacture, highly eiiicient in use, and simple in construction, an arrangement which can be manipulated with safety and ease when mounting a roll of paper in position with respect to the wrapping mechanism.

Another object of the invention of equal importance is the provision of a core for each end of the roll of paper in which core is incorporated frictional means for preventing overriding or backlashing of the roll of paper and which core, while being capable of these accomplishments may nevertheless be inserted in the end of the roll of paper in the conventional manner. This latter feature permits the use of standardized rolls of paper.

The present invention is intended to be used in connection with a bread wrapping machine such as that disclosed in United States Patent Nos. 2,276,590; 2,252,028; 2,235,503; 2,232,558 and 2,230,797.

Other objects will appear hereinafter.

The invention consists in the novel combination and arrangement of parts to be hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings showing the preferred form of construction, and in which:

Fig. 1 is a fragmentary perspective view of a bread wrapping machine showing my improvements incorporated therein;

Fig. 2 is a vertical sectional detail view of the paper roll mounting core block embodied in the invention.

The drawings illustrate the preferred form of construction by which the several objects of my invention are accomplished.

The conventional bread wrapping machine, as is evident from the several patents hereinbefore referred to, comprises side frame members I and l housing the bread conveying and wrapping mechanism, the latter not being shown in the drawings of this application, as such mechanism does not constitute any part of the present invention.

Associated with these frames l0 and H are one or more screw shafts l2, each having a suitable hand wheel |3 to facilitate rotation of these shafts. Extending parallel'with these shafts l2, between the frames I0 and II, are' stabilizer bars [4.

Spaced bracket elements are indicated at l5, and these bracket elements are provided with enlarged bearings |6 at their inner end portions through which the screw shafts l2 work. These bracket elements also provide depending feet I! bifurcated as at I8 to provide a seat engageable with the stabilizer bars I4. The bracket elements l5 extend outwardly from the side frames Ill and H, as at l9, and the extremities of these portions l9 provide bearings 20.

Associated with each of these bearings 20 is a stud shaft 2! having a reduced portion 22 bearing threads 23 for threaded engagement with a nut 24. The reduced portion 22 of the stud shaft 2| projects through a mounting disc 25 having fixed connection with the bearing 20 by means of a pin 26. Secured to the outer face 21' of this mounting disc 25 is a friction ring 28 formed of fiber or other suitable friction material.

The stud shaft 2| has an enlarged portion 29 which bears against the mounting disc 25. This enlarged portion 29 projects through an opening 30 formed in a core or plug 3| in which opening there may be positioned a suitable bushing. The enlarged portion 29 of the stud 2| has a head portion 32 which fits into a socket 33 formed in the plug 3 The plug 3| is freely rotatable upon the enlarged portion 29 of the stud shaft 2| and provides an internal flange 34 riding within an opening 35 formed in the friction ring 28.

The medial circumferential surface 31 of the plug 3| provides a tapered shoulder 38 which is adapted to engage the rim of the bore 39 through the roll of paper 39.

The plug 3| in its outer portion provides a recess or socket portion 40 into which fits the mounting disc 25 and. the friction ring 28 in a manner such that opposing faces of the ring 28 and the plug 3|, as indicated at 42, will have frictional engagement with respect to each other.

In bread wrapping machines of the type illustrated in the aforementioned patents, the paper roll 39 is intermittently rotated by a mechanism which exposes successively, sections of the web 43 of the roll 39 in the area of the wrapping operation. Mechanism of this type has a tendency to cause the roll to rotate suddenly and end with a slight jerk. In so acting, the paper roll 30 often overrides the intended degree of rotation of the paper roll and, as a result, considerable While I have illustrated and described the pre--' ferred form of construction for carrying my invention into effect, this is capable of variation and modification Without departing 'fromflthe spirit of the invention. I, therefore, do not Wish to be limited to the precise details of construe-- tion set forth, but desire to avail myself of such variations and modifications as come Within'the" scope of the appended claim.

Having thus described my invention, what I Claim as new and desire to protect by Letters Patent is:

A mounting core for a roll of paper comprising a non-rotating stud shaft, a mounting disc, means carrying said stud shaft and having connection with said mounting disc to prevent rotation of said mounting disc relative to said shaft, a paper roll supporting core mounted on said stud shaft and having a socket portion, a friction disc mounted in said socket and supportedby said core and adapted to have facial engagement with said mounting disc, substantially as described.
