Application December 6, 1949, Serial No. 131,485

4 Claims. (Cl. 2511-120) My invention relates to roll paddles and similar devices. 1

My invention relates more particularly to improvements in the construction of prying bars or paddles as they are known in the trade, for use in moving a variety of types of material usually found in cylindrical rolls or packages. Materials of the type mentioned may include all types of printing paper rolls, linoleum, metal foils and other cylindrical packages easily susceptible to damage at the edges or corners unless handled so that no damage can be done. Among paper mills, printers, warehouses, railroads and other handlers of roll paper, damage to the side is frequently sustained due to improper or careless handling of the roll paper. One element which assists materially in cutting down or eliminating damage to the corner of the roll is a proper roll paddle, one suiciently light and easy to handle so that al1 roll paper handlers will automatically reach for the paddle to use the same, and yet sufficiently strong and sturdy so that it will not easily become broken or get out of order.

The principal object of my invention is to provide an improved construction of roll paddle or similar device.

A further object is to provide a paddle of the type described which will be very light in weight, yet strong and rugged and capable of withstanding long and hard usage without becoming broken or out of order.

A further object 'of the invention is to provide a novel connection between the head and the neck of the paddle without the use of bolts, rivets or other fastening means whereby the connection is incapable of loosening.

A further object of the invention is to provide a novel construction of paddle wherein the operating or use head is constructed of cast magnesium Iand connected to a tubular metallic neck during the casting operation.

Other objects and advantages will be more apparent from the following description wherein reference is had to the accompanying drawings,` upon which Fig. 1 is a front elevational View of my improved roll paddle;

Fig. 2 is a side elevational view of the same;

Fig. 3 is a side elevational view showing the manner in which the paddle is used to move rolls of paper about; and

Fig. 4 is a changed position view showing the manner in which the roll paddle is applied to permit engagement of the upper flattened face of the head.

In the embodiment of the invention which I` have chosen to illustrate and describe, I have,

shown a paddle which may essentially consist ofv three specific elements, a rod-like handle por-- tion I0, a tubular sleeve or neck portion l2, and.

hung upon a nail or other support. The lower,r

portion Il of the wooden handle is turned down; and adapted to be telescopically inserted into the tubular neck portion I2, being fastened therein. by friction or by a Wood screw I9 which may be employed if desired.

The neck portion I2 is preferably a steel tube.-

approximately two inches in diameter, with av Wall thickness of le inch. The portion thereof' which is connected to the paddle head is attenedi by having the two side walls 20 and 22 tapered tok a point 24, in which condition the tubular neck: is set into the mold and the head I4 is poured. about the same so that after the head is cast it is integrally connected to the neck portion and the two parts can not become separated except by breaking either the head or the neck portion.

The head I4 is preferably cast of as light a metal as possible, yet in view of the fact that it is the working portion of the paddle, it is necessary that it be tough and hard as possible. Accordingly, I prefer to cast the same of magnesium which I have found to be very satisfactory for the purposes herein described.

The head I4, as shown, is provided with a comparatively flat face 26 terminating in the nose 28, the material extending therefrom in a taper as shown to form the back or heel portion 30 thereof. The face 26 is somewhat wider than the neck I2 or handle Il), thus effecting more of a gripping space for engaging cylindrical rolls or similar packages.

Upon the upper end of the face 26 I have provided a further flattened portion 32. This is for engaging a roll of paper P with the same when the paddle is in the position shown in Fig. 4, the purpose of the attened face being to prevent and edge engagement at any time with the surface of the roll of paper P.

I have fround that with the construction shown, wherein a magnesium head, a steel neck and a wooden handle are assembled in the manner described, the possibility of breakage is extremely remote. Since most of the breakage of roll paddles occurs just above the head I4 in the tubular neck portion I2, the provision of the steel tubu-A f3 lar member aords at this point a maximum of strength so that such breakage as occurs in wooden paddles is not possible With the construction provided.

While I have illustrated and described a speciic embodiment of the invention, it Will be apparent to those skilled in the art that changes and modifications may be made in the exact details shown, and I do not wish to be limited in any particular; rather what I desire to secure and protect by Letters Patent of the United States is:

1. A paddle for moving rolls of paper comprising a magnesium head, an elongated tubular portion telescoped'into the end of said neck'por' tion, said tubular neck being ilattened at" itsend with the head cast about the sameto'integrally connect said headv and said neck.

3.v A comparatively light yet sturdy paddleof. the typedescribed having/in combination a head;r a neck and' a handle portion, said 'handle portion 4 being a Wooden rod having a reduced end, said neck comprising a metallic tube with the reduced end of said wooden rod telescoped into one end of the same, the other end being ilattened with the head cast about the same to integrally connect said head and neck.

4. A comparatively light yet sturdy paddle oi' the type described having in combination a head, a neck and a handle portion, said handle portion being a wooden rod havingV a reduced end, said neck comprising a metallic tube with the reduced end of said Wooden rod telescoped into one end of the same, the other end being flattened with the' head cast about the same to integrally connect rsaid head and neck, said head having a nose portion at the lower edge of its face.
