I WRAPPING-MACHINE.

Specification of Letters Patent.

Patented Mar. 30, 1915.

Application filed March 19, 1914. Serial No. 825,829.

To all whom it may concern:

Be it known that 1, WILLIAM C. CUTLER, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful WrappingMachine, of which the following is a specification.

This invention relates to a machine which is adapted for wrapping pies, cakes, loaves of bread, or other articles, and the object of the invention is to provide a machine of comparative simplicity which is effective in operation and which will very rapidly wrap the articles.

Referring to the drawings: Figure 1 is a plan view of the rotating frame. Fig. 2 is a side elevation of the machine, showing the lower plates in alinement with the upper plates, portions of the paste magazine being broken away to more clearlyshow parts behind the same. Fig. 3 is a vertical cross section taken diametrically through the machine. Fig. 4 is a lower plan view of one of the plate lifting disks. Fig. 5 is a similar view of another plate operating disk. Fig. 6 is a similar view of another plate operating disk. Fig. 7 is a similar view of another plate operating disk.

The machine comprises a pedestal 1, in the upper end of which is slidably mounted a stem 2 toa non-revoluble spider frame 3, having four arms 41, as shown in Fig. 1. Revolubly mounted on the pedestal 1 being supported by a shoulder 5 is a revoluble table 6 having four arms 7, the table 6 having a bevel gear 8 which is driven by a segmental gear 9 mounted on a shaft 10, arranged transversely in the pedestal, the gear .9 being adapted to rotate the table 6 oneeighth of arevolution for each complete revolution of the shaft 10. The shaft 10 also carries a cam 11, which is adapted to act against the. stem 2 to reciprocate the" frame 3. The shaft 10 is driven by a pulley 12 over which runs a belt 13, the latter serving as a carrier for the wrapped pies or other articles indicated at 13, Fig. 3.

Rigidly carried by each arm 1 is a hollow stem 14: carrying a cupped disk 15 on its lower end, with an ejecting disk 16 mounted on a stem 17 which is slidable in the hollow stem 14, and a compression spring 18 serves to' normally hold the disk 16 seated in the disk 15 with the end of the stem 17 protruding above the arm 4:, this protruding end being depressed when passed over by a cam 19, which is fixed on the rotary table 7 and rotates therewith.

The paper plates are designated at 20, Flg. 2, and are arranged in a pile on a platform 21 which has telescoping legs 22 supported on a bracket 23 which projects from a vertically slidable rod 24. A chain 25 is connected with the rod 24 and a reel 26, and when the spider frame 3 moves down at every other stroke it will cause the reel 26 tobe actuated by a mechanism about to be described and lift the bracket 23 and plates with it an equal distance, bringing the uppermost plate of the pile into contact with. the pick up disk at. which is in line therewith. As the plates are removed from the pile 20, and as the bracket 23 has a fixed stroke, it is necessary to gradually feed the pile of plates upward from the bracket 23, to maintain the uppermost plate at a fixed distance with respect to the having a pin 33 which engages a shoulder 31 on one of the standards 29, so that at each upward movement of the standard 29 the arm 32 is oscillated and the pawl 31 which is located near the pivoted arm 32 is given a slight amount of motion sufficient to advance the ratchet 30 the distance of one tooth, and thereby rotate the cam 27 and lift the table 21 and pile of plates 20 the height of one plate. In order to allow the plate to come in contact with the pick up disk a, the table 35 is provided with a hole 36, to permit the passage of the pile of plates, as indicated in Fig. 2. The reel 26 has a notch 37 cut in it near one edge thereof and the notch is adapted to be engaged by a pawl 38 carried by a rock arm 39 pivoted on shaft 10 on which the reel 26 is mounted. The end of'the arm 39 is con nected by a chain 41 with the spider frame chain 25 restores engages in either size " notch 43 or 44 of the controlling disk 42 to prevent its reverse movement and the pawl 38 at each stroke of the arm 39 engages in a notch 43 or a notch 44 and rotates the controlling ratchet 42 the distance of one tooth at each down stroke of the spider frame. The depth of a shallow notch 44 prevents the pai'vl 38 from entering the notch 37 in the reel 26, so that the actuation of the reel 26 only takes place at every other stroke when the 'pawl 38 engages in a deep notch 43, which allows it to also engage in the notch 37 and when so engaged, the down stroke of the arm 39 turns the reel 26 counter-clockwise and lifts the bracket 23 with additional plates, while during the upward stroke of the arm 39 the weight of the parts which are carried by the reel 26 to its original position, the reel when actuated thus having an oscillatory movement while the controlling ratchet 42 has a revolving movement and is checked by the retaining pawl 45.

The rotating table 6 is provided with pivoted tipping plates 46, as shown in Fig.

3, which are earned on stems47 slidable on the table 6, and the outside of the plate is slightlyfover set to the stem, so that-when the stem is lifted, as shown at the left in Fig. 3, the outer side of the plate overbalances and tips the plate to the left, thus causing the pie plate which rests upon it to slide off onto the conveyer 13. The stems 47 are lifted by a stationary cam 49 on the table 35. In order to guide the pie plate properly when tipped over onto the conveying belt, I provide inclined ways 50, as shown in Figs. 1 and 2.

On each arm 7 is an adhesive roller 51 which is mounted in a box 52 containing adhesive, so that as the table carrying the disks sweeps thereover they receive adhesive on their edges which is used in lifting the plates from the pile, lifting wrapping papers from the table, and for securing the wrapping paper in place.

' The disk15 has a continuous rim 53, as shown in Fig. 4. The disk 15) has a rim formed of segmental. projections 54. The disk 15 has a series of small segmental projections 55, and the disk 15 has a plain rim 56 adapted to have letters or numbers for stamping the wrapped ie. The rims 53, 54' and 56 are each supplied with glue after each of their reciprocations by an adhesive roller 51, which sweeps thereunder as soon as the disk is raised, and before it again descends, rim 55 not receiving any glue because slightly raised other disks as clearly shown in .Fig. 2.

In the operation of the machine as the table 3 descends, it carries down all of the disks, and the disk 15, the rim 53 of which is supplied with adhesive, comesin contact with a plate 20 and lifts thatplate with it above the level of the as the table 3 raises. The rotating table 7 then moves the cam 19 over the stem 17, which depresses the latter and ejects the plate from the disk 15, and the plate falls down upon the arm A. The ejection of the plate occurs at the moment the arm A is with a sheet of paper, not shown, and placedon the arm by hand and the projections coming in contact'with the sheet of paper,

picked it up during the upward stroke of the table 3. The rotation of the table 5 carriesthe plate deposited on arm A in a direction to bring it under the disk 15", which is now holding the paper. During this rotative movement of the plate while carried by the table 6, the pie, not shown, is placed in the plate by hand and when the plate contain ing its pie arrives directly underneath and in register with the disk 15, the cam 19 depresses the plunger of disk 15", which ejects the paper, and the paper falls down upon the rim of the plate, which is covered with adhesive by reason of its previous contact with the continuous rim 53 of the disk 15", which had lifted the plate. The table 6 turns farther and brings the pie covered with its paper under the disk 15, and as the latter descends, its projection 55 firmly presses the paper against the rim of the plate, causing it to tightly adhere thereto and seal the pie therein. The table 3 then rises and the table 6 continues to turn until the sealed pie arrives underneath the disk 15. The table 3 descends and the rim 56 of disk 15 numbersor stamps the sealed pie, and while the rim 56 had been supplied with glue this was but incidental, and not disadvantageous as the raised letters or'numbers on the rim receive but little glue and this is harmless. The table 3 then raises, and the table 6 revolves and carries the sealed and numbered pie, and the stem 47 rides up on the stationary cam 49, and the tipping plate 46 discharges the wrapped pie onto the carrier 13.
