The pull-in device comprises a roller 33 having pivots 35 moving in slots 35, cut in the brackets 16. These slots being generally curved, preferably having their upper portions nearly vertical, and their lower portions inclined backwardly. The portion of the towel between the two feed rolls [8 and 22 being carried around the roller 33 is kept under tension by the weight of the roller 33. When the bight I5 is released by hand at the end of the use, the roller falls to the bottom end of the slot taking up the toweling and pulling it into the cabinet, but

when the toweling is being pulled from the cabinet, the tension of the towel raises the roller by moving the pivots to the upper ends of the slot. Thus the roller forms an internal bight l5, corresponding to the external bight i5.

The towel coming from the pull-in device is carried over a guide rod 35 and then backwardly over the used towel feed roll 22. This latter feed roll is journaled in a pair of levers 3?, which levers in turn are pivoted to the main frame coaxially with the feed roll it and arcuate slots 33 are cut in the brackets to receive the journals of the feed roll 22 and thereby permit the levers 3! to move about the axis of the clean towel feed roll it to carry the used towel feed roll 22 with them toward and from the used towel 23. The surface of both 'feed rolls. is preferably roughened. It will be clear that as the roller 33 comes in contact with the rods 20 and 36 when the bight is fully withdrawn, the toweling is locked against further withdrawal.

The roll 23 of used towel may be carried upon a wooden roller having journals 39 turning in notches it in. the main frame, and the purpose of the pivoting of the feed roll 22 is to permit the surface of that roller to bear against the siu'face of the used towel on. the roll 23 at all times so to turn the latter to wind up the used: towel as the feed roll 22 is rotated. A spring 4! connects the free end of the levers 3? with the bracket it to hold the feed roller 22 in contact with the surface of the roll of. used toweling 23.

Means are provided to insure the co-ordination between the movement of the clean towel feed roll and the used towel feed roll, comprising, in the form illustrated, a sprocket wheel 42 on. the shaft of the clean towel feed roll connected by a chain d3 to a sprocket it on the shaft of the used towel feed roll to insure that the peripheral movement of the two rollers shall be at all times identical, thus insuring that the length of toweling available for use shall be invariable. A ratchet @5 upon the shaft of the used towel feed roll 22 cooperates with a pawl 46 upon the main frame to insure that the feed roll may not be moved in the reverse direction.

Means are provided upon the device for insuring that whenever toweling is pulled from the device for use, that the portion actually to be used will be fresh. This means that the bight 15 will include the same pie-determined amount of clean toweling each time without danger that the same portion of towel will be repeatedly withdrawn from the machine from the pull-in device. It is desirable to permit more toweling to be withdrawn in the bight l5 than will actually be soiled, since only the central portion of the bight is convenient to use. Thus, it is possiibleto permit an idle portion of the toweling to be withdrawn on each end of the bight before and after the portion. intended for use, while still presenting fresh toweling for use. 7

- This system insures the maximum convenience to the user consistent with every portion of the towel being used and no portion being used more than once.

To accomplish these results there is mounted upon the brackets It, a device for locking the release of the pull-in device comprising an arm 5 having pivoted thereto a dog 5| having a weighted portion 52, normally to hold the dog across the slots 35 in the pathway of the pivots 34 of the roller 33. The purpose of this dog is to permit the pivots 34 to move backwardly through the slot by the mere tilting of the dogs 5|. A stop 53 is provided tolimit the reverse movement of the dog so that the pivots 34 may not be moved forwardly except by the movement of the arms 59 about their pivots.

The rod 32 is loosely journaled in levers 54 pivoted to the main frame, and this rod also extends through slots 55 in upwardly extending brackets 55 upon. the brackets Iii so that the rod 32 is guided for vertical movement by the slots 55. but this vertical movement is accompanied by a rotation of the levers 54 about their pivots.

These levers 54 are arranged to control the lock and release of the arms 50 through a suitable lever mechanism, which, as illustrated, comprises a bell crank lever 51 pivoted to the rear of the bracket H3 having one arm connected by a link 58 with one arm of the lever 54, and having its other arm anchored to the frame by a link 59 and spring 50, the strength of the spring being such as normally to raise the movable rod 32 to its uppermost position.

A link 6i has a pivot 62 moving in a slot 63 in the link 59 and has pivoted at its other end at 34, an arm E5 which in turn is pivoted to the bracket It at 66. This arm 65 has an inter-locking surface 61 adapted to engage the free end 68 of the arm 59 to limit the movement of the arm 59 except when. the arm 65 is raised and the latter arm may also have a projecting finger 59 to extend over the end of the arm 50 to limit the downward movement of the arm 65 when the link 59 is in its lowermost position.

With this construction there is rather extensive movement of the link 59 as the mechanism is operated, and only a very small movement is required of the arm 55. This difference is taken care of by the lost motion provided by the slot 63.

When the towel is first fed through the machine in the manner described, it is wound on the used towel roll to the point when the roller 33 is at the bottom of its slot, the toweling being substantially taut between the rods l9 and 20, so that no appreciable amount of the towel will extend downwardly out of the front of the machine.

In normal operation, when the stretch of toweling between the rods i9 and 29 is grasped by the hands, the upper reach of the towel first depresses the rod 32 and gives a small length of towel. At the same time the lower reach of the towel raises the roller 33 until its pivots. engage the dog 51, since at this time the locking arm 65 has been freed by the depression of the movable rod 32, the'pivots slide past the dog releasing the roller 22. The further pulling out of the towel, therefore, feeds a certain stretch of toweling from the fresh towel supply and releases substantially the same amount of toweling from the internal bight by raising the roller 33 to the topof its slot. This action operates the feed rollers to wind up the under side of the toweling coming from the roller 33, by the roller 22, which is being forcibly rotated through the medium of the chain 43 by the unrolling of the fresh towel supply roller.

It will thus be seen that the supply of toweling for use cannot be wholly withdrawn. from the internal bight by pulling up the roller 33 in its groove, since this is prevented by the dog 5|. The roller 33 is only released for movement when the tension on the stretch of clean toweling on the roller 32 corresponds to that which is required for operating the mechanism. It is thus impossible to put the fingers into the b ight and pull out the soiled toweling reeving the toweling over the fingers. The toweling can only be removed when it is subjected to a tension which requires a firm grasp of the cloth and thus it is insured thateach withdrawal of the towel will be accompanied by a re-wind of a portion. of soiled toweling and an unwind of clean toweling. The parts may be so proportioned as to feed different quantities of toweling, but in general it is not necessary that .all of the toweling which is withdrawn from the machine shall be re-wound. upon the used towel roller. The user will soil only the central portion of the exposed toweling and if the entire free bight of the towel were immediately fed under the take-up roll, it would unnecessarily include a large portion of the towel surface which had not been used. It is preferable, therefore, to adjust the feed to an amount substantially equal to the actual quantity of toweling which is to be soiled. It is possible, therefore, to utilize the first portion of the bight for one using as the used portion of the bight for the subsequent using and still not present to any user the soiled toweling for use.

With the above construction, it will be observed that the mechanism provides fresh toweling for each userand definitely prevents the toweling being fed to present soiled toweling, and at the same time it is economical of the toweling, moreover, the mechanism is simple and reliable to operate.

Since certain changes may be made in the above construction and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above ,description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.

One of the important features of this device is that it affords a practical cabinet in which the toweiing is readily available at any time desired, 'but which has no toweling either clean or soiled visible at any time, except during use. This is a practical feature of importance, which, so far as applicant is aware, has never been in use.

It will also be noted that the operation of the mechanism is such as to prevent the re-use of the same towel since the soiled toweling is automatically fed back into the machine as soon as released, and when new toweling is taken for use, the surface portion of it must necesarily be clean towel. This prevents any person, even one unable to read instructions, from becoming infected by the use of soiled toweling.

Where a portion of the towel is permanently exposed for use, subject to replacement when desired, many persons wiping their hands hurriedly, use the protruding portion without taking the trouble to feed new towel through the machine.

Under such circumstances, the user himself uses the soiled towel and leaves the doubly soiled towel for the next comer to use. The possibility of such action is entirely eliminated by this machine by reason of the fact that this machine causes the total disappearance of all the towel portion previously exposed, whether used or unused, into a separate and distinct compartment of the locked towel case and it definitely releases on each using an amount of toweling sufiicient completely to replace the portion of the towel which has been used.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is:
