SUPPLY CONTROL FOR PAPER TOWEL DISPENSERS Filed Dec. 31, 1941 ATTORNEYS.

' This invention relates to controlling the pa; per supply'in paper towel dispensers, and relates particularly to means designed to prevent the use of unauthorized paper in dispensers which manufacturer and quality It is customary for manufacturers and distributor's of paper towels to provide dispensers for towels and also to supply rolls of toweling to be used in the dispensers. In order to discourage use of unauthorized toweling ortowel'ing-of an inferior grade, it has becomejeoin'mon practice to provide dispensers with means to prevent "any but a particular type of towel roll beir'i'ginserted,

and then provide toweling therefor in rolls which-- cannot readily "turers.

1 Some of the dispensers 'now in use include be duplicated by other manufac- "tion to prevent; insertion of a roll of normal length, unless it is cut in a particular manner to enable it to pass over the stud or projection; A

shorter roll may be inserted but willnot be supported properly. In some cases, however, a roll which is considerably shorter than theleng'th properly used in the dispensers, will drop to the bottom of the dispenser and function very mu h in the manner intended for a properly supported! roll. v r

It is the objectof the present invention to .provide a simple and inexpensive means for insuring against the use of unauthorized paper in a towel dispenser and especially jtolins'ure against the use of short rolls in a dispenser which has control means depending for successful functioning on the towel roll being of a predetermined length.

Other objects and advantages of the :invention are made apparent in the iollowing specification wherein the same is described in detail and wherein reference is made to the accompanying drawing illustrating one form of the invention.

In the drawing:

Fig.- 1 is a sectional view through a towel dispenser embodying the present invention;

Fig. 2 is a sectional View taken on line 11-11 of Fig.1; a

Fig. 3*is a perspective view'of a roll of paper toweling of the kind illustrated in Figs. 1 and 2; i

Fig. 4 is a perspective view of a portion of the bottom wall of the dispenser illustrated in Figs. 1 and 2; s

Fig.5 is a perspective view of one of the towel supporting members illustrated in Fig. 1 and particular means to support a rollpof toweling at its-ends only and means consisting of a stud or .projec-F s Fig. 6 "is a perspeetive view'ojr amo ifiea ferm' er the sup orting member illustrated in Fig. 5.

These supports incline forwardly and toward "the roller 13 sothat the-supply roll l'ithe ends'jorwhich a I I rest upon "the supports it wingravitate "toward and tiofne to rest against the'roller lt. Each or the supports 15 presents a relatively'narr'ow supporting surface so that the supmy roll 14 must be Ofa, brefiteimined minimum length ill.

While a supply roll sufiicien'tly shorter than standard length maybe placed in the dispenser, itwiu ii tjrest upon the supports 15.; Transverses extending members l9 and 20 which reinro'ree the side walls I] are preferablypositioned to prevent insertion or a-s'upply 'rouexcept the normal path in which the stud I6 is positioned. Other advantages of this structure and method of controlling the paper supply in towel dispensers are set forth'in Patent No. 2,232,968 for Towel dispenser and supply roll therefor, issued to' Lawrence L. Price and Maurice E. Maltby on February 25; 1941.

It has been found, however, that if the unauthorized or inferior grade of paper attempted to be inserted inthe dispenser is considerably shorter than a standard roll, it will pass between the innermost edges of the supports, and rest entirely upon the bottom I0 of the dispenser where it will in some cases function as efliciently or nearly as efliciently as thoughjit were properly supported upon the supports l5. 1' .1. The present invention insures against success-' ful operation of the short supplyroll through the structure now to be described.
