PAPER TUBE WINDING APPARATUS Fned Jan. 1o. 1952 Patented July 7, 1953 PAPERTUBE 2,644,376 WINDING APPARATUS Joseph Hf'Raymond, Chicago, Ill. application Jauary 1o, 1952, serial No. 265.776
This invention concerns wound paper tubes `or cones such as are used as handles for the' confection commonly known as cotton candy, and has more particular reference to apparatus for facilitating the winding of such paper cones.
Heretofore the paper tubes or cones'employed for the handles of cotton candy confections were rolled up or wound by hand. Needless to say this was tedious and dicult, and uniformity in the length and size of the cones Was practically impossible. Manual Winding of these paper cones and the attendant lack of uniformity not only made it difficult for the concessionaire to correctly judge the right amount of cotton candy to be attached to the cone, but also made it extremely difficult and often impossible to nest a supply of cones one inside the other for corrJ servation of storage space.
It is, therefore, the purpose of this invention to provide a simple and inexpensive device by which paper tubes or cones of uniform size and shape may be easily and quickly wound.
More specifically it is the purpose and object of this invention to provide a simple crank operated mandrel equipped with `a hold-down clamp which is automatically moved to and from its operative position clamping of a piece of paper to be wound onto the mandrel, by the taking up of lost motion in the driving connection between the mandrel and its crank.
With the above and other objects in View, which will appear as the description proceeds, this invention resides in the novel construction and ar rangement of parts substantially as hereinafter described, and more particularly dened by the appended claims, it being understood that such changes in the preciseembodiment of the here-' inafter disclosed invention may be made as come within the scope of the claims.
The accompanying drawing illustrates one complete example of the physical embodiment of the invention constructed in accordance with the best mode so far devised for the practical application of the principles thereof, and in which:
Figure 1 is a perspective view of the paper cone winding device of this invention;
Figure 2 is a group perspective view of the component parts of the device shown separated from its support;
Figure 3 is a cross sectional view taken through Figure 1 along the plane of the line 3-3 and illustrating the clamping bolt in its open or releasing position;

, 2 trating the clamping bolt in its operative clampiing position; A
Figure 5 is a longitudinal sectional view taken through Figure 4 on the plane ofthe line 5-'-5; and
Figure 6 is a perspective view of a paper cone wound upon the apparatus of this invention.
Referring now more particularly to the accompanying drawing it Will be seen that the paper tube or cone Winding device of this invention comprises in general av support 5, a mandrel 5 rotatably mounted on the support and a driver 'I for imparting rotation to the mandrel 6 and clamping and releasing motion to a clamping bolt`8 by which a piece of paper P to be wound into a tube or cone may be secured to the side of the mandrel to rotate therewith.
While the mandrel may be of elongated cylin1 drical shape and formed of any suitable material it is preferably conical and constructed of light weight metal such as aluminum. Its large diameter end is turned downto provide a journal 9 and a shoulder I0. The journal 9 is freely rotatably received inthe bore II of a bearing I2 on the support 5 with the shoulder Ill abutting the adjacent end of the bearing.
A bore I3 extending axially into the mandrel and terminating in a crossbore I4 adjacent to the shoulder I 0 has a cylindrical stem I5 rotatably received therein. This stem is part of the driver 1 and has an enlarged outer end I6 of substantially the same diameter as the journal 9. v Y
' Hence, the driver 1 when connected with the mandrel passes freely through the bore Il in the supporting bearing to enable assembly of the parts. A small pin I'I seated in a radial hole` in the journal 9` and projectingY into anl annular groove I8 in the stem I5 holds the driver and readilyA apparent the wall of the bore II holds the pin I'I in place. The assembly of the parts' is thus quite simple.
The stem I5 hasfa length sufficient to extend intothe mandrel as far back as its crossbore I4, land at this point has fan eccentric driving pin 2| projecting into the cross bore to be received in a notch 22 in thefside of the clamping bolt 8 which vis slidably received in the crossbore. As seen best in Figures 3 land 4, this connection between the stem and the bolt 8 translates rotation of the driver relative to the mandrel into endwise motion of the clamping bolt, and since the bolt has a head 23 thereon its movement into the crossbore is limited. The head 23 overlies a substantially nat surface 26 on the side of the mandrel normal to the axis of the crossbore so that when retracted to clamp a piece of paper to. be Wrapped into a cone to the mandrel the. head lies below the surface of the cone.
When the clamping bolt is in its released position (shown in Figure 3) with its head 23 spaced from the iiat surface 24, the eccentric pin'2l on the driver engages the side ofthe notchY 22,
nearest the head of the bolt. Counterclockwise rotation `of the driver, as seen in Figure 3, for
Iapproximately one-quarter of a turn, relativeV to the mandrel, causes the eccentric pin 2l b-y its engagement in. the. notch 22 to draw the clamping bolt down into the crossbore to its opl1 erative position (Figure 4) in which the underside of the head of the bolt may clamp a piece of -paper to the mandrel.
Preferably the head of the clamping bolt is made relatively thin with a concave underside to assure a secure clamping action between the head and the paper resting on the flat surface 24. The position of a paper blank as it is pre :2"
sented to the mandrel for clamping thereto by the head of the bolt, is indicated in construction lines .in Figure l. Attentionis directed to the fact that the vblank is slightly longer than the -conical portion of the mandrel and prefer-s Ie ably has its outer end portion cut on a slant.
As Will be readily apparent, rotation `of the driver 'I in addition to imparting clamping and releasing motion to the bolt 8 also transmits rotation to the mandrel as soon as the lost mo= tion in the connection between the driver and mandrel afforded by the pin 2| and slot 22 is taken up. This lost motion driving connection is perhaps best illustrated by a comparison of' Figures 3 and 4 from which it is clear that'sliding motion of the clamping bolt necessary to shift the same from its released to its clamping position is eifected by counterclockwise rotation of the driver with respect to the mandrel the degree necessary to engage the head of the bolt With the flat surface 24 on the mandrel or a piece of paper resting thereon. Obviously, the head of the clamping bolt in the operative clamping position thereof limits further rotation of the driver relative to the mandrel so that the latter is constrained to rotate With the driver upon continued counterclockwise rotation of the driver.
Upon initial clockwise motion of the driver relative to the mandrel releasing motion is imparted to the clamping bolt, the limit of this releasing motion being defined by the engagement of the eccentric pin 2l With the bottom of the notch 22.
In the operation of the device, a precut blank of paper P to be Wound into a cone has its long edge positioned against the exterior yof the mandrel with the edges of a square corner thereof bearing against the side of the clamping bolt beneath the head thereof and against the adjacent end of the tubular bearing I2. This locates the blank both laterally and longitudinally of the mandrel. During the first few degrees of rotation of the crank the clamping bolt is drawn into its operative clamping position and 4 as soon as the head of the bolt clamps the blank of paper to the flat surface 24 on the mandrel the mandrel rotates with the driver and with his free hand the operator guides the Winding of the blank about the tapered length of the mandrel. Obviously, the crank is turned in the direction to maintain the clamping bolt in its operative position until the entire blank is Wound upon the mandrel With the small diameter end of theV cone 2S thus formed projecting a slight distance beyond the tip of the mandrel. Thereafter the small end of the cone 2B is bent over as at 21 and While the operator holds the same at its bent over end retrograde rotation is iniparted to the crank to eiiect releasing motion Y of the clamping bolt and thereby enable the op-= erator to slide the finished cone off the mandrel.
The support 5 preferably is formed as an angle shaped bracket having the tubular bearing I2 Welded endwise to its upstanding leg 23, and the horizontal leg 2S of the bracket may have a plurality of holes 3G to facilitate the securement of the bracket to a supporting surface with the axis of the bearing horizontal.
From the foregoing description taken 'together with the accompanying drawing it will be readily apparent that the paper cone Winding device of this invention. is characterized by an economy of parts and by simplicity of oonstruc tion and low cost, and that it greatly facilitates the Winding of paper cones and tubes, it being understood that Where tubes of uniform diameter are to be Wound, the mandrel is cylindrical rather than tapered or conical.
