To all whom, it may concern:

Be it known that T, SAMUEL 1L. AimLson,

ers for Paper Receptacles, of which the following is a full, clear, and exact description.

This invention relates to improvements in paper receptacles and method of and formers for producing same. The object of my invention is to produce a cheap and efficient paper receptacle, such as a drinking-cup, from a previously formed blank, preferably cone-shaped. One of the advantages of my improved receptacle is that it is a-unitary structure, that is to say, the bottom of the receptacle is' integral with the body thereof; hence it makes possible the formation of the receptacle in a single operation by a suitable mechanism pres ently to be described. In view of the fact that the bottom of the receptacle is integral with the body thereof, the chance of leakage is eliminated. Furthermore, as the bottom of my improved receptacle is ribbed it is strong and durable.

I will now proceed to describe my invention in detail, the novel features of which I will point out in the appended claims, reference being had to the accompanying drawings, forming part hereof, wherein Figure 1 is a side elevation of my inn-- proved receptacle, partly in section; Fig. 2 is a sectional plan view thereof,

, Application filed August 8, 1917. Serial No. 184,204

a hollow body portion 12 closed at one end by a bottom 13, the open end of the receptacle being surrounded by a flange 14. The bottom 13 of the receptacle is integral with the'body portion 12 and consists ofa plurality of concentric ribs 15 formed by corrugations 16. The flange 14 can be of any desired configuration that will lend rigidity to the body portion 12. In this instance the flange '14 consists of the reversely directed wings 14 and 14 which are integral with the body portion 12. The receptacle is formed out of a conical blank or cone 17 (Fig. 4) by a special forming device which will hereinafter be described.

To transform the cone 17 into a receptacle such as above described, ll, by means of a special device, force the apex 18 of the cone toward the base 19 by a step-by-step operation producing the corrugations 16, the formation of the flange 14 beingthe last step in the operation.

One of the former elements comprims a conical die-member 20 (Fig. 5) consisting of a plurality of movable parts 21, 22, 23, 24 and 25, said movable parts being associated with springs26, 27, 28 and 29, respectively. The die-member will be secured to a suitable base-plate 30 of a press. Flg. 11 illustrates a form of press that may e used, .but the particular mechanism for op erating the die-members is not important to the present invention.

The other former elements consist of cooperating recessed die-members 31 and 32 The member 32 forms the bottom- 13, while the member 31 forms the flange 14. The former-members 31 and 32 35 and 36. By this means I am able to adjust the flange-die 31 relatiyely to the bottom-forming-die 32 for a purpose to be described. The cone 17, out of which the receptacle is formed, is preformed by any To form a receptacle such as a. drinking-cup, a cone 17 will be placed upon the conical die or former 20 (see Fig. 5). After the cone has been placed upon the former 20 (see Fig. 11) thespindle 37 of the press will be lowered by manipulating the handle 38 to rotate the gear 39} which meshes with teeth 40 cut in the spin:

dle 37. en the former 32 has been low iic ered sufiiciently, the apex 18 of the cone 17 will-enter the central recess 41 of the former v32, as indicated in Fig. 7. The flange die' plate 30, against the tension of its spring 26 (see Fig. 8) until the tapered end of the conical former-member 22 enters the recess 42 of the bottom-forming-member 32, carrying a portion of thecone 17 with it, as indicated in Fig. 9. A continued downward movement of the s indle 37 will force the conical former-mem er 22 toward the base as well asthe former-member21 until the tapered end of the conical formermember 23 enters the recess 43 in formermember 31, carrying'a portion of the cone 17 with it. A continued downward movement will cause the conical former-member 24 to enter recess 44 in former-member 32, carrying a portion of the cone with it. The bottom 13 will now be complete. At about the time that the edge 45 of former-member 24 forces the paper against the bottom 46 of the recess 44, the inner surface 48 of the flange former 31 will contact with the cone 17 adjacent the. edge 47 of the fixed member 25 of the former 20, as indicated by dotted lines 48 Fig. 5. After the formermember 24 has entered its recess 44 a continned downward movement of the spindle forming the flange 14 as their respective parts upwardly,

37 will cause the said member 24 to move inwardly, thereby causing the annular rib 49 of the flange former 31 to enter the space 50 between 'members 24 and 25, thereby indicated in Fig. 10. When the spindle 37 is raised, the compressed springs 26, 27, 28and 29 will move thereby restoring them to normal position and also stripping the now completely formed receptacle oil the die or former 20.

- The central recess 51 of the bottom 13 is 1' formed by the "member 21, the next annular recess 52 by the member 22, the next annular recess 53 by the member 23 and the outer annular recess 53 by the member 24. The flange-former 31 is nade adjustable in order that it can be positioned to contact with' the conical form or blank, on the former 20, at about the time that the edge 45 of former-member 24 strikes the'bottom 46 of its cooperating recess 44' in the bottom-former 32. The shape of the flange 14 I can be changed by substituting other suitable formers in place of the former-31. To

forma flange such as is indicated in Fig. 3, I may substitute a flange-former slightly smaller in diameter than the former 31; hence it will contact with the conical blank- 17 higher up than the former 31 and ac-' cordingly the inside wing 54 will be longer than the outside wing 55. Having now described my invention, what I claim isi A device for forming receptacles, comprising a former to receive a hollow paper-.

shell, said former consisting of a plurality of collapsible sections, in combination with a former having a plurality of peripheral recesses to receive the edges of said col- .lapsible sections.

a conical formerto receive a" preformed conical shell, said former comprising a plurality of collapsible sections, com ressible springs to keep said sections exten ed, and means to collapse said sections and arranged to receive. the edges thereof during the collapsing operation.

4. A device for forming receptacles with a bottom having'a' plurality of annular recesses to form annular ribs, consisting of a conical former to receive a preformed conical shell, said former comprislng a plurality of collapsible sections, compressible springs to keep said sections extended, a former to collapse said sections and arranged to receive the edges thereof during the collapsing operation, and a former positioned .to coiiperate w1th the formersection at the base of the conical-former to produce a flange around the mouth of the receptacle.

5. A device for forming receptacles with a-bottom having a plurality of annular receases to form annular ribs, consisting of a conical former, to rece ve a preformed com cal shell, said former comprising a plurality of collapsible sections, compressible springs to keep said sections extended, a former to collapse said sections and arranged tov 1'8 former to produce" :a flange around. the A -120 mouth of the receptacle.
