To all whom it may concern: I

Be it known that I, ELFORD F. 1300mm, a citizen of the United States, residing at Torrington, county of Litehfield, State of Connecticut. have invented an Improvement in Bread \Vrapper-Sealing Machines, of whichthe following is a specification.

This invention has for its object to provide a simple and inexpensive machine for end and bottom sealing the wrappers of loaves of bread.

It is of course well understood that custom requires that loaves of bread be independently wrapped in wax paper. The sheets of paper after being wrapped about the loaves require to be secured which has been done both by the use of string and by heating the wrappers and melting the wax therein so that the flaps of the wrapper will adhere together. This sealing operation has been heretofore performed, so far as I am aware. by complicated and expensive ma chines requiring either gas or electric connections. In lieu of these complicated machines I have. devised a machine so simple in construction and operation that it can be produced at triliin z expense, cannot get out of repair and can be used by any person skilled or unskilled, thus placing it within the reach of'small bakers and enabling them to effect an important saving of time and expense over tying the wrappers with string and enabling them to quickly and effectively seal each wrapper.

In the accompanying drawings forming a part of this specification, Figure 1 is a. perspective of my novel machine; Fig. 2 a per spective of a loaf of bread wrapped and scaled; Fig. 3 a perspective of one of the slug holders detached: Figs. 4 and 5 detail views on an enlarged scale illustrating: a simple and convenient means for detachably securing the slug holders to be sealing 'ilatcs; Fig. 6 a transverse section ot the ma chine on the line indicated by 6 in Fig. 1, looking in the direction of the arrow; Fig. 6 a detail view corresponding therewith showing a scaling plate inclined from the bottom outward instead of standing vertical to the bed; Fig. 7 a transverse section on the liueindicated by 7 in Fig. 1, looking in the direction of the arrow: Fig. 8 a vertical section on the line indicated by 8-8 in Fig. 7, looking in the direction of the arrows, and Fig. 9 is an enlarged detail sectional view illustrating a practical mode outward from the of constructing the slug holders and the drawer.

1O denotes the frame or body of t chine which may be made of wood and may be placed upon a table or otherwise con vementl supportw'l. Over the frame and secured thereto a bed 11 of sheet metal.

12 denotes the adjustable sealing lates be tween which the loaves of bread c passed cndwise, and which may stand vertically" to the bed, as in Figs. 1, and T, or mav in line vertica plane, as in Fig. (3, depending upon whether the ends oi the loaves to be operated upon are parallel ta; each other or inclined outward iron. each other. The scaling plates may be formed integral with or rigidly secured to bases 3.3 which are adapted to be moved ina'arti or; outward ov r the l ed. he ter c oi the bases are attached in any suit .hman nor to carrying pieces 14;, as by P1?! of Screws 1;"; which pass through top strips 1 3 and engage the carrying 49965.

lho cm 4 in: pieces have respectively right and left threaded engagement with shafts 1? which pass transversely t-ino'iign the frame and are held against long tudinal ins'wenicnt in any suitable manner as by means cl 18 on the shafts which bear against plates 19 on the fra .ie. The carrying pie ar shown as provir ed with nutallio lxeariugsfi ll which are engaged by the thieudfi; of the shafts. One or both ends of the axe provided with linger wheels 21 for some?! icncc in rotating the shafts to adiast the sealing plates toward or from each o-Y's over the bed.

In my novel machine the heating: o t wrappers to rii'e t end and bottom 5 i1 5 thereof is eliecl'cd it; me" s at rl 22 which are held i l jflfl iliiti with the plates and with the under side of These slugs may be made terial that will not part with in idly. for example i rifl's. As e -3r must have an men. it follows that may be hen l th rein whip-out a. cost. The p fo nd cilnr z of We wrap 'iors arc placed in the solo s 1'5. whi h are simply boxes with one s de emo ed which muv be in of wood or n fai as fol-red and are lined with asiu suitable heat r sist" matcrl: by ill in Fig. 2 Tue slug: h li plates in 1! attached to the scalin able manner. in ile present instance transversely between the scaling shown the holders as provided with headed pins 25 which engage slots 26 in the sealing plates and retain the holders in place, as clearly shown in Fi s. 1 and 4. The slugs project from the hol ers sufficiently to cause them to lie in close contact with the plates and impart heat: thereto.

The bottom sealin of the Wrappers is effected by means of s ugs placed in a drawer 27 which slides in ways 28 secured to the frame. Springs 29 upon the ways act to raise the drawer and retain the slugs in contact with the under side of the bed, the frame being cut away as shown, to receive the drawer. The drawer is preferably lined with asbestos or other heat resisting material in the same manner as slug holders 23. The receiving end of the machine is toward the left, as seen'in Fig. 1. It will be noted that the sealing plates flare outward at their receiving ends to permit the wrapped loaves to be' conveniently inserted. The operator places the wrapped loaves plates with the bottoms of the loaves resting on the bed and the ends bearing against the sealing plates which are adjusted sumciently close to each other to press the end flaps of the wrappers down tightly but at the same time permitting the loaves to be pushed ahead as succeeding loaves are placed in the machine, the feeding being by hand. As the bottom folds of the wrappers pass over the portion of the bed directly over the drawer, they will be heated bv the slugs in the drawer sufliciently to melt the wax in the wrappers and cause the overlapping edge at the bottom to adhere to the ply'of paper under it. The portions of the sealing plates contiguous to slug holders 23 are heated by the slugs in the holders and the wax in the end flaps of the wrappers is melted and said flaps are causedto adhere to the flaps under them, as indicated in Fig. 2. Each wrapped loaf as it is pushed forward to be sealed, pushes the loaves ahead of it forward between the sealin plates, which are extended some distance eyond the slug holders so that the relatively cool forward ends of the sealing plates will partly cool the sealed end flaps and the relatively cool portion of the bed forward of the drawer will partly cool the sealed bottom flap so that before the'loaves pass from the machine, the sealings of the wrappers will have become sufliciently cool and set to permit the loaves to be handled without danger of breaking open the sealings.

Having thus described my invention I claim:

1. A machine of the character described comprising a metallic bed, metallic sealing plates between which the wrapped loaves are passed, a drawer for heated slugs adapted to slide underneath the bed, and holders for heated slugs having one side removed and adapted to be placed adjacent to the scaling plates with the slugs in contact therewith.

2. In a machine of the character described, the combination with a metallic bed and metallic sealing plates, of slugs adapted to be heated and holders for said slugs having one side'removed. said holders being adapted to be placed adjacent to the surfaces to be heated with the slugs in contact with said surfaces.

3. A machine of the character described, comprising a metallic bed, metallic sealing plates between which the wrapped loaves are passed endwise, a. drawer for holding heated slugs lying under the bed, ways for said drawer and springs in the ways whereby the drawer is raised to retain slugs in the drawer in contact with the bed.

4. A machine of the character described comprising a metallic bed, metallic sealing plates between which the wrapped loaves are passed and which are provided with slots and holders for heated slugs having headed pins for engagement with said slots whereby the holders may be. detachably secured to the sealing plates, for the purpose set forth.

In testimonv whereof I affix my signature in presence of two witnesses.

ELFORD F. DOOLITTLE.
