nits s rarns rants STEFAN STAMIROWSKI, OF NEW YORK, N. "551, ASSIGNOIEK- 0F ONE-HALF TO THOMAS J. FRUIN, OF NEW YORK, N. Y.
Application filed November 4, 1914.
To all whom it may concern:
Be it known that I, STEFAN STAMmowsKI, a subject of the Emperor of Austria-Hun gary, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Wrapping'Paper Cutters, of which the following is a specification.
This invention is an improved wrapping paper stand or cutter for dispensing and cutting rolls of wrapping paper, the object of the invention being to provide an improved machine of this kind which enables the end of the roll to be readily grasped after a piece of the paper has been out off therefrom, the invention consisting in the construction, combination and arrangement of devices hereinafter described.
Other objects will appear and be better understood from that embodiment of my invention of which the following is a specification, reference being had to the accompanying drawings forming part hereof, in
In the accompanying drawings :--Figure 1 is a side elevational view of a wrapping paper stand and cutter constructed in accordance with my invention, showing the cutting blade in raised position, uncovering the end of the paper roll. Fig. 2 is a detail side elevational view of the operative parts of the cutter, showing the cutting bar in its lowered position, and also showing one of the standards removed for the sake of clearness. Fig. 3 is a rear elevational view. Fig. 4: is a cross sectional view taken on the line el4: of Fig. 2, and Fig. 5 is a detail perspective view of a portion of the paper guide bar and trip arm connected therewith.
The base 1 and top 2 of my improved stand are connected together by a pair of standards which have inturned flanges 4 and 5 at their lower and upper ends, respectively, secured by means of screws to the base and top, as shown. The standards are offset at 5 and on the inner sides of the 0dset portions are bearings 6, open at their upper sides, for the reception of the ends of the core 7 of the paper roll 8. These standards are preferably of the form here shown but may be made of any other suitable form and said standards are provided on their upper ends with forwardly extending arms 99, respectively. The arms are provided Specification of Letters Patent.

with apertures 10 for the reception of screws 11 which form bearings for a guide portions 17 and are connected together at their outer ends by a cutter blade 18.
It will be understood that the guide roll 12 to which the cutter blade is connected is adapted to be turned in the bearings on the arms 9 9 so that the cutter blade may be either arranged in the elevated position shown in Fig. 1 or the lowered position shown in'Fig. 2.
The bracket 13 at the end of the guide roll is provided with ratchet teeth 12 @n the inner side of one of the arms 9 is a pawl 22 the pivot of which is at the lower end there of as at 23. This pawl, when the cutter blade is raised, bears against the stop portion 17 of one of the arms 16 so as to hold the cutter blade and the brackets of the guide roll in elevated position and when the cutter blade is in lowered position, shown in Fig. 2, the said pawl engages one of the ratchet teeth 12, and, hence, locks the cutter blade also in lowered position.
A guide bar 241: for the paper from the roll 8 has its ends secured to the arms 9-9 by means of suitable screws 25 or other suitable devices. A trip arm 26 is pivotally mounted on the inner side of one of the arms 9 as at 7 and is provided at its inner end with a projection 28, which, when the trip arm is in the lowered position shown in Fig. 1,
' raises the pawl 22 out of engagement with the ratchet teeth 12 of the guide roll bracket and holds the said dog in the required position to cause it to catch against the stop portion 1.7. A paper guide bar 29 connects the outer end of the trip arm with an arm 30 pivotally mounted on the arm 9 opposite to that on which the trip arm is mounted. Hence the bar 29 is vertically movable with and is carried by the trip arm 26. A stop in the form of a pin 26 mounted on one of the arms 9 and engaging with the guide bar 29 limits the upward movement of the guide blade and prevents the same from engaging with the roll 12 as shown in Fig. 2. A suitable balance is employed to raise the cutter blade from the lower position shown in Fig.
2 to the initial elevated position shown in Fig. 1. This balance is in the form of an adjustable weight 31 mounted on a rod 32 which is secured to and projects tangentially from one of the brackets 13 secured to the guide roll.
The paper from the paper roll 8, is first passed over the fixed guide bar 2% then under, nearly around and over the guide roll 12 and under and caused to extend outwardly from the movable guide bar 29 which is carried and supported by the trip arm 26. The end of the paper may be readily grasped and whenthe paper is pulled it causes the bar 29 to move upwardly and thereby cause the projection 28 of the trip arm 26 to disengage the pawl 22. The pull onthe paper causes the roll 8 to turn in the direction indicated by the arrow in Fig. 1", the said roll 8 causing the bracket 13 to turn therewith and, hence, lower the cutter blade to the position shown in Fig- 2 by the time the required length of paper has been drawn out and so that the said cutter blade bears on the upper side of the paper. The paper may then be readily torn off or cut oil along the edge of the cutter blade, as willbe understood, and as soon as this occurs, the paper bein no longer under tension, the roll 8 will be then turned by the balance in the direction opposite that indicated by the arrow in Fig. 1 so as to restore the cutter blade to its initial elevated position and thus leave the end of the paper roll which projects from between the bars 24l29 exposed, unobstructed and in condition to be readily grasped when another piece of paper is required.v
While the cutter blade is in lowered position and the paper is being cut, the pawl 22 engagement with the ratchet teeth 12 holds the blade in such position, as will be understood. As soon as the paper has been cut ofi", the descent of the bar 29 by its gravity causes the trip arm 26 to turn a sufficient distance to cause the projection 28 thereof to disengage the pawl 22 from the ratchet teeth 12 and thus permit the balance to restore the cutter blade to its initial elevated position. To prevent the pawl 22 from turning backwardly too far a stop 33 is provided on the inner side of one of the arms'9.
While I have herein shown and describeda preferred form of my invention, I would have it understood that changes may be made in the form, proportion and construction of the several parts without departing from the spirit ofmy' invention and within the scope of the appended claims.
I claim 1. A paper cutter of the class described, a guide roll mounted for oscillating movement, a cutter blade carried by the said guide roll, means to normally turn the guide roll in one direction to raise the cutter blade, a locking element to hold the guide roll with the cutter blade in lowered position, a trip for the locking element, and a paper guide bar for engagement by the paper drawn from a paper roll and to actuate the trip to cause the latter to move the locking element to releasing position.
2. In apaper cutter of the class described, a stand having bearings for the core of a paper roll, a guide roll mounted on the stand for oscillating movement, a cutter blade carried by the guide roll, means to normally turn the guide roll in one direction to raise the cutter blade, a locking element to hold the guide roll with the cutter blade in lowered position, a movable guide bar for engagement by the paper drawn from the paper roll and over the guide roll, and a trip for thelocking element actuated by the said guide bar to move the locking element to releasing position when the tension of the paper against the guide bar relaxes.
3. In a paper cutter of the class described, in combination with means for mounting a paper roll, a paper guide roll mounted for oscillation, a cutter blade carried by the guide roll, means to normally turn the guide roll blade, a locking element to hold the guide roll with the cutter blade in lowered position, a movable trip to release the locking element, and a guide bar carried by and movable with the trip and for engagement bythe paper drawn from the paper roll and guide roll.
45. In a paper cutter of the class described, in combination with means for mounting a paper roll, a paper guide roll mounted for oscillation, a cutter blade carried by the guide roll and adapted to be raised and lowered thereby, a locking element to hold the guide roll with the cutter blade in lowered position, a movable trip to release the looking element, and a guide bar carried by and movable with the trip and for engagement by the paper drawn from the paper roll and guide roll.
