DEVICE FOR SEALING WRAPPED PACKAGES.
Specification of Letters Patent.
Patented May 6, 1913.
. Application filed December 26, 1912. Serial No. 738,625.
To all whom it may concern:
Be it known that I, WILLIAM Boaonnn'r, a citizen of the United States, residing at Rockford, in the county of Winnebago and the State of Illinois, have invented certain new and useful Improvements in Devices for Sealing Wrapped Packages, of which the following is a specification.
This invention relates to devices for sealing wrapped packages and more particularly to the sealing of loaves of bread which have been wrapped in paraffin paper or paper with a like or similar coating applied to the portion of the wrapper which is to be sealed.
The object of this invention is to construct a sealing device for this purpose which shall be simple in its construction and inexpensive to manufacture and which shall perform its functions automatically when wrapped packages have been passed through the device.
The further object is to provide a novel construction in which the sealing of the packages shall be performed by a heating element and the sealed portion beheld in a set position by a cooling member until the seal has become fixed.
In the accompanying drawings: Figure 1 is a plan view of the device, a portion of one of the runner plates being broken away. Fig. 2 is a side elevation of the sealing device with a portion of the heating guard plate broken away. Fig. 3 is a vertical section on the line 33 of Fig. 2. Fig. 4 is a plan section on the line 44 of Fig. 2.
The sealing device may be suitably supported in a machine for automatically and mechanically wrapping loaves of bread or on a convenient stand or rest where bread wrapped by hand may be quickly and conveniently passed through the sealer.
The longitudinal runner plates 1 consist of an upper and lower member spaced apart, and the supporting brackets therefor are secured between said plates.
The heating elements 5 may' be of a suit able construction, having here shown a. common type of electric resistance heater in which the current is supplied through the wires 6 to each of the two elements. The
The operation of the sealing device is as follows: The heating elements are maintained heated to a suflicient degree and loaves of bread or any other article wrapped in paraflin paper or paper to which has been applied a similar coating at the sealing portions, are placed upon the runners in front of the mouth pieces 9, passed along the runners coming in contact first'with the heating elements and then with the cool side members. The side members are to be adjusted to suit the width of the package being wrapped, and when a package is passed between the side members 1t will be compressed to a slight degree therebe tween because of the tensional support of said side members. As the ends of the package that are to be sealed contact the heated elements the parafiin or like substance which the paper contains, becomes diffused, and passing to the cool sides of the device are cooled, ,thus setting the diffused sub stance and sealing the package. The packages may be entered one after another, each succeeding package moving the preceding package along. The time required for diffusing the substance is but momentary but of course varying with the degree of temperature to which the heating elements are maintained, so that packages maybe passed through the device as quickly as they can be wrapped.
It will be seen that the 0 ration of the sealing device is exceeding y simple and enables packages to be sealed very economically and quickly, thus making it a great labor saving device that maintains a high efiiciency.
I claim as my invention:
1. A device for sealing wrapped packages comprising supports carrying two oppositely positioned side walls having longitudinal continuous faces forming a passage having an entrance and discharge end, and a heating member carried by each of the side walls, oppositely positioned, and at a point intermediate the entrance and discharge ends of the walls, the heating face of each member being substantially in the plane of said side wall faces, and the outer edges of the heating members adjacent the side walls being heat lnsulated from said side walls.
2. A device for sealing wrapped packages comprising supports carrying two oppositely positioned side walls, each comprising a spaced entrance and body end lying substantially in the same plane, a heating member interposed between each of said entrance and body portions and connected thereto, the face of the heating member forming with the faces of its adjacent side walls, a continuous wall, and means con necting the opposite side walls and the base for holding said walls yieldingly in position.
3. A device for sealing wrapped packages comprising supports, two oppositely positioned side walls having longitudinal continuous faces forming a passage, the entrance end of the walls having diverging wing sections, an opening in each wall, the openings oppositely positioned and; at a point intermediate sald entrance end and the opposite end of the walls, a heating member positioned in each of said openings having its heating face substantially in the same plane as that of its side wall and forming with its side wall a continuous face, and means connecting the two opposite walls and the supports and adapted to hold the walls yieldingly in position.
4. A device for sealing wrapped packages, comprising supports, two oppositely positioned side walls having longitudinal continuous faces forming a passage, the entrance end of the walls having diverging wing sections, an opening in each wall, the openings oppositely positioned and at a point intermediate said entrance end and the opposite end of the walls, a heating member positioned in each of said openings having its heating face substantially in the same plane as that of its side wall and forming with its side wall a continuous face, the heating members bein secured to the side walls by heat insulating connections, and means connecting the two. opposite walls and the supports and adapted to hold the walls yieldingly in position.
5. A device for sealing wrapped packages holding the side walls yieldingly in position.
6. A device for sealing wrapped packages comprising a support, two oppositely 'positioned side walls having longitudinal continuous faces forming a passage having an entrance and discharge end, an opening in each side wall, oppositely positioned and at a point intermediate the entrance and discharge ends thereof, a heating member positioned in each opening'having its heating face in a plane substantially with that of its side wall, each side wall carrying fixedly supporting member adjacent its two ends, said supporting members being carried by said support and movable thereon transversely to said passage to move the side walls bodily, and means for holding the side walls yieldingly. together.
7. A device for sealing wrapped packages comprising two parallel disposed runners having an upper and lower member, a sup-' port for the runners, and a side wall posisaid side walls and being held slidable be-' In testimony whereof I have hereunto set .tween saidupper and lower members of the my hand in presence of two subscribing witrunners, and means for holding the two side nesses.
