Patented Nov. 13, 1951 .UNITED' STATES. PATENT OFFICE.
WAX PAPER SEALER Zellen W. Gunn, San Rafael, Calif.
Application February 27, 1950, Serial No. 146,593
1 Claim. 1
My present invention relates to wax sealers and more particularly to a sealing device for use in sea-ling wax paper coverings around rolled newspapers, etc.
In rural as well as city locations it is customary for newsboys to wrap their papers when making delivery in wet weather. Such wrapped papers are usually thrown into the yard or onto a porch from the sidewalk. Frequently they land in puddles of water or lay exposed to rain or snow for some time before being picked up.
It is customary for the delivery boy to roll the paper in a waxed paper covering with the corners folded over and stretch a rubber band over the rolled unit. Many times the rubber band breaks or is displaced when the paper lands on the porch or shrub-cery and the paper is exposed to wet elements which, in many instances, ruins the paper for the reader.
In my present invention I have designed a sealing device upon which the paper is wrapped and the waxed paper sealed in one operation both on the ends and the sides.
The principal object of my invention is to produce an improved sealing device for waxed paper covered rolled newspapers and the like.
Another object is to produce a sealing device for waxed paper covered rolls which seals the side of the roll and the folded over ends in one operation.
Other objects and novel features comprising the construction and operation of my invention will appear as the description of the same progresses.
In the drawings illustrating the preferred embodiment of the device:
Fig. 1 is a plan view of the sealer, the extension cord being broken ed for convenience;
Fig. 2 is a cross-section taken on the line 2--2 of Fig. 1;
Fig. 3 is another cross-section taken on the lines 3-3 of Fig. l, and
Fig. 4 is a fragmentary perspective view of a waxed paper wrapped newspaper ready for the sealer.
Referring more in detail to the drawings, I0 indicates a sheet metal apron having side portions H located at ninety degrees on either side of the apron. Under the front end of the apron I0 is fixed a U shaped insulated member having a lower portion l2 and upturned end portions 13. This insulated member is closed on the top end portions and three sides and is preferably formed from a heavy asbestos material which not only insulates electricaly but also thermally. The top III ill
and inner vertical sides of the turned up portions of the U member are closed by the sheetmetal apron and extensions of the side portions H. In the side portions ll over the U member are located angularly disposed pockets I4. The lower portion of the pockets [4 are in line with the corners formed by the apron I0 and side portions H but the sides of the pockets tilt outwardly away from each other so that the top of the pockets result in a curve as shown in Fig. l. The U shaped member may be attached to the device by means of screws [5 through the metal cover portions 86 of the side portions ll. Inside of the U shaped member 12 is an insulated core member H the ends of which are turned upwardly at ninety degrees as shown in Fig. 2 and secured to the cover plates It by th screws l8. An electrical resistance wire coil 19 is located on the core m mber 1?. The two lead ends of the resistance wire, as indicated at 2B, are connected to a suitable socket 2| to which is attached a conventional cord and plug 22 which may be plugged into any convenient house receptacle.
In operation a newspaper is rolled into a small roll and placed upon a sheet of waxed paper 23 the width of which is greater than the length of the rolled newspaper. The newspaper is now rolled up in the waxed paper covering which is of sunlcient length so that several layers of waxed paper covers the rolled newspaper at any point around the roll. The ends 24 of the waxed paper is now folded over and the rolled newspaper is forced down on the apron iii of the sealer. The folded end portions slide down in the angular 1. portions l i of the side portions H of the apron Ill. The surface of the apron Ii! and the side portions 14 are exposed to the heated chamber of the U shaped member l2. Within a second or two the rolled newspaper is sealed in the waxed paper 23 both at the folded end portions and along the entire roll.
Due to the fact that the waxed paper around the newspaper comprises several turns, the ends and the sides are sealed between each layer as the waxed paper is waxed on both sides. Even though one of the layers such as the last turn should get opened no moisture can reach the newspaper rolled inside because of the multiple covers and seals between each cover. With such a seal no rubber bands are needed.
It will thus be seen that I have designed a very simple device which is eilicient and inexpensive and fast in operation and while I have shown the details somewhat in diagrammatic form yet it is to be understood that I may vary r 3 the design and proportions and may use equivalent structure within wide latitude while still remaining within the spirit of the appended claim.
Having thus described my invention what I claim as new is:
An improved wax sealer for sealing waxed paper covered rolls having folded end portions comprising an apron having side portions, a heated chamber formed from an insulated U shaped member fixed to extension portions of said side portions and provided with an electrical heating resistance unit, pockets located on the 4 opposite sides of said side portions being angularly disposed outwardly from the top face of said apron to the top edge of said side portions.
