JOHN 33. LEIDEGKER} OF A LAM EDA', CALIFORNIA.

PARER DISPENSER.

Application filed November My invention is.- an improved paper dispensing device.

The main difficulty in dispensing rolled paper isthat the loose end can not be readily grasped. The roll often turns so that the loose end is at the rear away fromthe wrapper and it requires considerable time to'turn it in the proper'position so that a sheet may be torn off.

The object of my invention is to provide a dispensing device wherein the end of the paper is always readily accessible.

C ther objects are to provide a dispenser which issimple in construction, inexpensive to manufacture and efficient. in operation.

In the drawing I have shown one formof my invention, but it may be embodied in other forms and in this specification and appended claims, I wish to cover my invention in whatever form it maybe embodied.

Referring to the drawing: 6

Figure 1 is a side view of my improved paper dispensing device.

Figure 2 is a top plan view of the same.

Figure 8 is a side view of the same with the side plate removed.

Referring more particularly to-the drawing, the numerals l and: 2 indicate a pair of upright roll supporting posts which. are joined at the top by a horizontal bar 3 and secured their baseto a suitable surface. Detachably mounted on the posts 1 and 2 is paper guide frame 4 which comprises side walls 5 and 6. The-walls 5 and 6 are secured to the posts 1 and 2 at their lower end by bolts extending throiurh ears 7 and 5% on the walls 5 and Grespectively andinto the posts 1 and 2. The walls 5 and 6 are secured at their upper end to a horizontal mounting bar 9 which has a groove 10 formed therein for the reception of the bar 3. By this means the frame 4 is securely mounted on the roll supporting posts.

The front wall 11 of the frame 4 has the inner surface inclined slightly inwardly as at 12 to prevent the paper from binding as will be later described. A knife 13 is mounted on. the lower edge of the wall 11 against which the paper is torn.

A downwardly inclined guide plate 14 is mounted between the sides 5 and 6 and e:-;- tends from the bar 9 to adjacent the lower ed ge of the front wall 11, leaving an opening 15 for the passage of the paper.

A roller 16 is mounted on a bale 17 near the top and rear of the frame 4. The bale 9, 1922. Serial No. 599,795.

17 is journaled in the sides 5 and 6 and counter weights 1 8 and 19 are suspended. to said bale below the journals to keep the bale in a normal vertical position. The bale works through slots 20 and 21 in the plate 14'.

Vertical guide rods 22 depend from the upper end of the plate 14 and a rider 23 is positioned between them and restsupon the paper. roll'24 which" is journaled intheuprights 1v and-2. The rider 23 actsas a. brake against the paper to prevent it. from* une winding any faster than desired.

A tensionv plate 24 lies on'the bar 9 under whichthe'paper is threaded, thence over the roller 16 and down through the opening 15. As the endof the paper is pulled the tension against the roller 16 causesit to swing forwardly as shown-in dotted'linesin-Figure The path of the paper through the frame a has thus been increased. When the paper is torn on the knife l3-with the roller in the forward position the tension on the paper is released and: the weights 18 and 19 swing the roller 16 to its normal rear position,

allowing the paper. to lie along theplate 14 7 which'is ashort'erdistance to the opening 15 than when the roller is" swung forwardly and the surplus paper protrudes from the said opening to form a ready hold when a further supply of paper is. requiredi,

The slack producing mechanism and the mechanical method of causing asla-ckmay be adapted to feeding webs of'paper or other material, whichhavean intermittent feed; andmay beused in machinery where'a slack is necessary as in motion picture cameras and projectures, certain types of bagmaking machinesand soforth. In" which case the cutterknife 13 would be omitted, the bar 9 and the opening 15 would function as in and out guide members respectively. The roller 16 does not function as a free rotating roller to allow easy passage of the paper but has a certain amount of friction on the web to pull the paper when under tension and drawnt-o the position shown dotted in Figure 3.

The method of operation is to allow the loose untensioned paper to have a short path between the in and out guides, which may be likened to resting on the base of a triangle 1a; and when the web is tensioned and pulled the carrier roller 16 draws the web to follow the upper and vertical sides of the triangle as shown in Figure 3. Thus when the tension is released the roller 16 swings back to the position adjacent the base 14, the web drops on the base; and the two sides of the triangle being longer than the third the surplus paper projects beyond the out guide 15 as a slack.

Having described my invention, I claim:

1. Dispensing means for a roll of paper revolvably mounted on a horizontal axis comprising a horizontal guide edge spaced from the roll and lying substantially in the horizontal plane of the axis thereof and a yoke pivoted between the guide edge and the roll having weights associated with the free ends thereof so as to normally occupy a vertical position with the base of the yoke presented higher than the roll of paper so as to swing forward with the paper for abnormally increasing the unrolled length thereof when the paper is advanced over the guide edge. 7

2. Dispensing means for a roll of paper revolvably mounted on a horizontal axis comprising a horizontal guide edge spaced from the roll and lying substantially in the horizontal plane of the axis thereof and a yoke pivoted between the guide edge and the roll having weights associated with the free ends thereof so as to normally occupy a vertical position with the base of the yoke presented higher than the roll of paper and guide means frictionally engaging the paper rearwardly of the base of the yoke.

3. A dispensing device for a revolvably mounted roll of paper comprising a horizontal guide edge mounted in front of the roll and spaced therefrom, and a yoke pivoted between the roll and the guide having its pivot disposed below the roll axis and its base higher than the roll and having means associated therewith for normally holding the same in a vertical position.

4;. A vertical frame allowing a roll of paper to be revolvably mounted therein, side walls extending forwardly from the frame, a substantially vertical front wall between the side walls and spaced from the roll, a slanting intermediate wall descending from 5. A vertical frame allowing a roll of paper to be revolvably mounted therein, side walls extending forwardly from the frame, a substantially vertical front wall between the side walls and spaced from the roll, a slanting intermediate wall descending from the top of the frame toward the lower edge of the front wall so as to form a slot there with allowing a strip of paper to be guided over the top of the frame and between the intermediate and front walls and through the said slot and a yoke pivoted to engage the underside of the paper between the intermediate and front walls so as to be swung forwardly toward the front wall when the paper is pulled on.

6. A vertical frame allowing a roll of paper to be revolvably mounted therein, side walls extending forwardly from the frame, a substantially vertical front wall between the side walls and spaced from the roll, a slanting intermediate wall descending from the top of the frame toward the lower edge of the front wall so as to form a slot therewith allowing a strip of paper to be guided over the top of the frame and between the intermediate and front walls and through the said slot and a yoke pivoted to engage the underside of the paper between the intei' mediate and front walls so as to be swung forwardly toward the front wall when the paper is pulled on, the said yoke having means for returning the same to an initial position associated therewith.

In testimony whereof I affix my signature.

JOHN F. LEIDECKER.
