14 Claims.

This invention relates to a towel dispensing apparatus for dispensing inter-folded paper towels, More particularly, the invention has for its object the provision of a dispensing apparatus and what I now consider for paper towels, which will be exceedingly cheap and inexpensive to manufacture and which will be of such construction that it will not be likely to get out of order when in use.

A further object of the present invention resides in the provision of a simple push button operating mechanism for apparatus of this class cooperating with a displaceable barrier which is shiftable with the operating mechanism from a position in which it is locked thereby and in which position it prevents access to the leading edge of a towel to another position in which the edge of the towel may pass over the top of the barrier. The barrier is adapted for automatic return movement by which movement it moves up back of the leading edge of the towel which is presented in a position in which it may be manually withdrawn by the user. Upon the barrier assuming the last mentioned position, it is again locked by the operating mechanism and the leading edge of the following towel which is ldrawn' out from the inter-folded stack upon manual withdrawal of the preceding towel descends in back of the barrier, so that it cannot be accessible for withdrawal until a further manipulation is made of the operating member. I

The present invention accordingly has for its objects the Vprovision of means and mechanism to provide for the foregoing barrier operations and to provide for the locking of the barrier .at its proper stage of operation to the general end that towel wastage may be discouraged.'

Further objects reside in the provision `of a simple apparatus and locking controls for a shiftable barrier in a towel dispensing apparatus.

Further and other objects of the present invention will be hereinafter set forth in the accompanying specification and claims and shown in the drawing, which shows by way of illustration a preferred embodiment and the principle thereof to be the best mode in which I have contemplated of applying that principle. Other embodiments of the invention employing the same or equivalent principle may be used and structural changes made as desired by those skilled inthe art without departing from the present invention and within the spirit of the appended claims.

In the drawing: Figure 1 is a front elevational view ofthe cabinet. The top and bottom' portions of the cabinet are shown separated by broken away lines to diminish the height of the figure. In this ligure certain portions of the front cover are broken away to show the interior construction;

Fig. 2 is a sectional view taken on line 2-2 of Fig. l and looking in the direction of the arrows;

Figs. 3 and 4 are detail positional views similar to Fig. 2 but on a smaller scale and with the parts in the leading edge of the towels in various positions assumed during the successive stages of operation; v

Fig. 5 is `a detail sectional View taken on line 5 5 of Fig. l and looking in the direction of the arrows. This view shows the operating mechanism for the barrier plate and the assembly mounting therefor;

Fig. 6 is a detail View of a modified operating mechanism;

Fig. 7 is a detail view showing the flanged construction for supporting the back plate from the top and side plates of the cabinet.

The cabinet comprises side and tcp portions Is and IIlt formed of one piece of sheet metal having bent over flanges such as IIif (Fig. 7) at the rear to provide abutments for supporting the back plate I2 and other parts. The back plate may be secured in any desired manner to these flanges as by spotwelding.' The back plate I2 (see Fig. 2) it `its lower end is bent inwardly as shown at I3 to provide a shelf-like support for the rear of the stack of towels.V1

Preferably the forward end of the sloping part I34 is turned over into a rolled configuration as indicated at Il?. Fixed to the side plates in any desired manner as by spot welding to clips I5 is another sloping bottom member It provided with a rolled overrear terminating end I'I. This member IBaffords support for the forward edge of the stack of towels. The forward edge of plate I6 is bent upward as shown at IBa. (Fig. 2, see also Figi); To this part Ia, triangular shaped guidin'g members It are also secured to form forward guides for the towelstack at the corners of the magazine. The cross-member Ita also forms a forward guide for the lower edge of the towel stack. Hinged to the side portions by loose rivets at point I9 is a hinged'cover Eil.` The cover member may be lccked to the top portion when in closed'position by the usual lock, the position of which is indicated at 2I. The cover member 29 may be providedwith a slotted opening 22 to permit visual inspection of the supply of towels within the supply magazine.

In Fig. 2f`the supply magazine is generally indicated by the reference numeral 23. The usual stack of inter-folded towels T is placed in this magazine. 'Ihe bottom of the magazine is defined by the sloping bottom portions l3-l4 and -5 IS-l'i which are disposed in the relation shown in Fig. 2, affording a magazine delivery outlet between the rolled over ends I4 and Il through which the leading end of each towel of the series may extend. Carried by the inwardly turned back flange portions Inf of the side portions Ills (see Fig. 2) is a lower plate and operating mechanism assembly shown in Fig. 5 (see also Fig.

2, which shows this flanges iilf by means of screws 30).. This assembly comprises a vertical plate 24 which is bent horizontally forward to afford a bottom at 25 which at the forward end, is bent upward at 26.

' The ultimate discharge aperture of the apparatus is dened at its bottom by the'upper edge of member 23 and at its top by the rolled over end Il of the bottom portion I6 and this discharge aperture constitutes the space through which the towels lafter'passing the magazine delivery outlet are discharged from the machine. At the left side of the apparatus as viewed in Fig. 2, is an angle clipI 2'! which is secured by spot welding to plate 25 and which affords a pivotal support at this end for a transversely extending shaft 28. At the right hand side of th-e apparatus is a sheet metal housing generally designated 29 in Figs. l and 5. This housing is secured in any desired manner as by spot vwelding at the bottom to plate 25 and at the back to plate 24. Its open side is closed by the lower part of the right hand side wall of theapparatus when the lower plate assembly is in place. Such lower plate assembly l may be secured in place by means of screws 38 (Fig. 2) which are threaded through the plate 24 and into a supplemental plate 3| which is se- .;ic cured by spot welding to the back of the vertical plate 24.

Referring again to shaft 28, this shaft, as previously stated, is journaled at the left in the clip f 21 (see Fig. 2) and at the right hand end of the cabinet this shaft extends through and is journaled in they wall of the housing 29. Normally disposed in front of the leading end'of the leading towel projecting downward between I4 and l'i is a shiftable barrier plate 32 fixed to and rotatable with shaft 28. As shown in Fig; 2, the shaft28 is disposed back of and .below the top of thetransversely extending plate 26. The barrier plate 32 may be provided with a resilient bumper 33 which abuts the plate 26 and limits the anti-clockwise movement of the barrier plate. Referring now to Fig. 5, as stated before, shaft 28 extends through the casing of the operating mechanism housing. This operatingr mechanism comprises both an operating and a locking mechl anism. Preferably such mechanism comprises `van operating button 34 fixed to a flat member K35 which at its forward end extends through a slot in the mechanism casing and which at`its rear is guided for sliding movement by a stud 33 extending through a slot 3l in the member `35. A spring 38 is preferably provided disposed and secured as shown to keep the operating button plate assembly in outer position but if desired, the spring cany be dispensed with and out- S Ward and inward movements of the operating member effected by hand. Fig.` 6 shows such modified construction of operating member.

' Fixed tothe end of the shaft 28 and within the mechanism casing is ya cam shaped disc 39 pro- 75 vided with alocling recessv 40 adapted to receive assembly secured to the a tongue 4| projecting forward from a depending rear end of the operating member. This arrangement serves to lock the barrier plate 32 against inward movement and prevent access to the leading end of the towel when the operating member is in its normal outward position (the position shown in Fig. 5). The barrier plate 32 is normally swung to the position of Fig. 2 by a spring 43 which is curled around the shaft 28 and secured to the cam disc 39. The other end of this spring preferably bears against the bottom of the case as shown. The barrier plate isncrmally swung to the position of Fig. 2 by resilient means such as 43-43a. The spring 43 is curled around the shaft 28 and secured to the cam disc 39 and the other end of such spring preferably bears against the bottom of the case as shown. Either one or both of such springs 43-43a maybe used as desired and such resilient means are stressed by such manipulation of the manually manipulable member or operating member 34e-35.

` Pivotally carried upon the operating member is a spring pressed pawl 44 normally urged against'a stop 45 on the operating member by the spring. The nose of this pawl is disposed so as to intercept the abrupt shoulder of the cam disc 39' upon inward manual movement of the operating member. Engagement between the pawl 44 and the shoulder occurs after the nose or finger portion 4l has been dis-engaged from the notch 4i! so as to unlock the cam disc 39, the shaft 28 and the barrier plate. Further inward movement of the operating member will cause thef'cam disc to be rocked clockwise to thereby swing the barrier plate 32 from the position shown in Fig. 2 rst to the dotted line posi'- tion of Fig. 3. This movement of the barrier plate will bend back the leading edge of the towel and ultimately after the barrier plate 32 moves past the dotted line position of Fig. 3 toward the full line position of Fig. 3 the barrier plate will clear the end of the towel, whereupon the end of the towel by its own resiliency will move from the dotted line position of Fig. 3 to the full line position of Fig. 3. At approximately the time when the barrier plate 32 reaches the full line position of Fig. 3 the pawl 44 will have rocked the cam disc 39 to such an extent that the pawl will trip over the shoulder of the cam disc 33 whereupon spring 43 comes into action to rock the shaft 28 in an anti-clockwise direction. This movement of the barrier plate willhold the leading edge ofthe towel in the position shown in Fig. 4. At this stage of the operation the towel can be withdrawn by the user grasping the leading edge and drawing it vout in the usual manner. The following towel will. be drawn down in the usual mannervbut such leading edge of the following towel will assume a position back of the barrier plate 32 (see the Fig. 2 position). After release of the operating member the lock will againfengage and the barrier plate will again be locked to prevent access yto the leading edge of the following towel until the operating member is again pushed inward.

The foregoing described arrangement provides a simple means for preventing towel wastage. Comparatively few moving parts are required and these are all of simple( construction and easy to manufacture. The mechanism further is one of such character that it is not likely to get out of order when in use. It may be desired to provide an-inspection opening in the sides lof the cabinet to permit inspection of the leading edge of the towel and allow it to be straightened if it should become inadvertently wrinkled or crumpled. For this purpose round openings 4G (see Fig. 2) can be provided in each side member lils. The openings are preferably disposed in the relation shown.

summarizing, the mode of operation is as follows: First, the barrier plate blocks access to a towel and is locked in such blocking position. Second, the push button is pushed inward and the initial movement unlocks the barrier. Further movement swings the barrier to allow the towel edge to fly over the barrier. Third, the barrier returns but it is now behind the towel :o that it holds the towel in accessible position for manual withdrawal. Upon release and return of the operating member the barrier is again locked.
