UNITED STATES TENT OFFICE 2,509,266 MANUFACTURE OF POWDER PUFFS 4 Claims.

This invention relates generally to the m'anu factu-r'e of hollow articles made by the integration of blanks of planar material and more par-now larly to powder puffs and methodsandmeans of making the same. This application is-a division of our application, Serial No. 109,0'7Ojf11ed Noveinb'e'r 9, 1946, now Patent 2,484 336, October 11,1949.

For the application of face powder and for-*siinilar uses powder puffs composedof a textile material casing having a tufted or chenille outer surface are in wide use. In accordance withprior art constructions and methods the casing are manufactured by taking two blanks and stitching the same together incompletely about the perimeters thereof to form an inside out pocket. A padding or stuffing is provided and the Docket-is manually turned'right side out by the use o'f a turning stick 'or similar projection. After the pocket is turned the open edges are manually connected by stitching -or cement. Such constructionand methods are subject to-se'verahdisadvantages. Many of the pockets are-damaged in the turning operation. It is 'difficult to place the stufling within the pocket so that it lies smoothly. The total number of operations is great with a consequent high labor cost. The tiirning operation puts-the cloth of the casing under excessive strain resulting "in many damaged puffs or the use of a heavier material with resuitant higher cost. The separate-closing of a portion of the edge of the pufi casing usually result'sin a'lack of uniformity of the edge-and the puckered appearanceof the last closed portion detracts from the *appearance of the entire pufi.

It is therefore; among the objects of the present invention to provide novel and usefulpowder pufi constructions and methods of makin'g same which avoid the above described disadvantages of the prior art.

Another object herein-lies in the -provisioni'of powder puff construction wherein-the intu-rne'd edges of the casing are simultaneouslyinterconncted in an adhes'ive inanne'r.

Another object lies in the provision 'ofipowder puffs wherein the padding or stuhing is in a laminar arrangement with separate laminations engaged by thecasing connection members of each of the separate casing elements.

Another object herein hes in an improved powder puff having greater durability and shape retaining characteristics.

Another object hereinlies in the provision of new methods, and steps therein, in thecproduction o'f pow'der puffs of the class described.

Another object therein lies in :the provision iflf novel :and useful means .for the :production of powder ipuifs of the class described wherein a large propnrtion :of :the operations are automatically performed, and wlnchimeans may besmanipu'lated -by-a single .operator having .a re1ativelyalow degree of skill.

.Inaccordancer with i the Linventionva powden-pufi 20 vis manufactured. by i first -taking Itwo teasing e1ements,-: 2i and 22-and placing upon the inner surfaces 23 and 24 thereof pad elements 25 and 26 respectively. Preferably prior to thi last described assembly, or simultaneously with the original blanking of an element such as the element 2| from the web of planar material 21 the periphery 29 is provided with a plurality of notches 3 I The element 22 has the periphery 30 thereof provided with similar notches 32. The notches 3| and 32 are preferably V-shaped and the edges thereof converge toward the center at points substantially equidistant with respect to said center. The notches therefore form the tabs 33 and 34. The circle alon which said points of convergence lie is approximate1y of the same diameter as the finished puff.

Thus, the puff 20 may be formed by taking an element 22 with the normally outer surface downward (see Fig. 13) so that in the case of a plush type puff, the pile extends downwardly and outwardly. Following this a pad element 26 is placed upon the surface 24 and then the tabs 34 are folded inwardly through the dot dash position of Fig. 13 to take the position shown in Fig. 13 in full lines. The element 2! has the pad element 25 placed against the surface 23 and the tabs 33 are folded inwardly. Following this a layer of adhesive till, indicated schematically in Fig. 13, is placed between the juxtaposed surfaces of the tabs 33 and 34. The adhesive 50 may be of any suitable type such as one containing an air drying solvent or may be one which is thermoplastic or thermosetting. The finished puff will appear in elevation as seen in Fig. 4, and in section as seen in Fig. '7.

In Fig. 14 another form of puff is shown which differs from that just described, in that the casing element 2| and the pad element 25 are omitted and have substituted therefor a back element 40a. The other parts being similar to those previously described, to avoid needless repetition, are given the same reference characters with the addition of the sulfix a. In the form of puff shown in Fig. 14, the adhesive may be provided in the form of a layer Ella lyin on the under surface of the back element 40a.

Another form of puff made in accordance with our invention is shown in Fig. where a reinforcing element 41?) is interposed between the tabs 33b and 342). Also a handle strap 42b is engaged between the element 4) and the tabs 33b. The reinforcing element 4H) may be secured in place by layers of adhesive 50b, or it may be a piece of fabric having a coating, on both surfaces thereof, of an adhesive material.

Any suitable type of adhesive material may be used in any of the adhering operations of assembly. Thus, we may use water soluble glues. The drying of these may be hastened by solvents of higher volatility such as alcohol. We can use natural or synthetic rubber cement. We have used cements which contain synthetic resins, for example of the vinyl polymer type. For adhesion through the use of heat, cements containing gutta percha have been found satisfactory. Obviously, the composition of the cement will vary with the nature of the materials being united, and with the means for producing setting.

The puffs 20, a and 20b produced as described have a pleasing appearance and durable construction. Since all of the perimeter of the puff is simultaneously integrated, undesirable irregularities and puckering are avoided. The puffs being made in a right side out manner require no damaging turning and are closed in a substantially single operation. Since the adhesive forms a flexible weld with the tabs and acts, where a sufilcient quantity of adhesive is used, to interconnect these to form a kind of ring, this retains the waist or pulled in portion around the edge of the puff in place and causes a uniform appearance thereof. This effect is even more pronounced in the form shown in Fig. 15.

The machine for manufacturing the powder puffs in accordance with the present invention has the details thereof shown in Figs. 1 to 8 inclusive. The machine generally indicated by reference character 45 comprises broadly; a first or bottom puff forming element 46; and a second or top forming element 41; a puff pressing element 48; heating means 49; second puff formin element inverting means 5i; first and second casing element holding means 52 and 53; and first and second casing element periphery bending or tipping means 54 and 55.

The machine is preferably mounted upon a base 56 which is slightly below normal table height for a seated operator. Thus the base 56 may be supported from a floor 51 upon legs 58. Such a positioning permits the operator to conveniently place powder puff components within the elements 46 and 4? simultaneously. The main operating pedals 59 and 60 are placed in a position convenient for foot actuation on the part of the operator.

The first and second elements 46 and 41 are in many respects substantially identical so that a detailed description of portions of one will suffice for the other. For clarity in the disclosure, a part on the first element 46 has an even ordinal and the corresponding part on the element 41 will have the next odd ordinal as a reference character.

The elements 46 and 41 have cup shaped houslugs 62 and 63 with cylindrical side Walls 64 and 65. Extending from the walls 64 and 65 are frusto- conical walls 66 and 67 which merge with the bottom or end walls 68 and 69 respectively. The housings 62 and 63 therefore form chambers in and ll, the principal openings of which are closed by the die elements 12 and 13.

The die elements 12 and 13 are generally of shallow cup shape and considering such cups as occupying a position shown in Fig. 8 have a bottom wall 14 and a top wall 15, an angular circular wall 16 and 11, and side cylindrical walls 18 and 13, respectively. The die element 12 is fixedly secured to the inner surface of the side wall 64 in any suitable manner as by the use of screws which extend through the wall 64 and enter the wall 18, said screws not being illustrated for the purpose of clarity. The wall 19 including the second bending or tipping means 55 generally is fixedly secured to the wall 65 in a manner similar to that used for securing wall 18 as described above. The top wall 15 and the angular wall 11 are integral and are movable as a unit with respect to the wall 19. Together the walls 15 and Tl form a piston or pressure head 8| which is con nected to the relatively free or outer end of the hollow piston rod 86. V

As best seen in Fig. 8, the wall 74 is provided with an annular row of air holes 82, and the angular wall 16 has another annular row of air holes 84. Similarly, the top wall 15 has an annular row of air holes 83 and the angular wall 11 has an annular row of air holes 85. The holes 85 extend through the stationary and movable parts thereof so that when the pressure head 8| moves down the air flow through the holes 85 is cut off. We have found this to be satisfactory,-

The bottom surfaces of the finger I0! restupon-the=surfaceilll of the wall 18: The upper surface of the finger Iill is maintained in position-by the under surface of the guide ring I09; thelatter having the guide shoulder I I I. Laterally thereof, the finger IfiI is supportedbetween an adjacent pair of finger vertical guides, I I3 and I I-S-Which projectup from the surface I91. The

finger I0! is indented on the under surface thereof to form front and rear depending projections I I1 and H9. An annular flange I 2| projects upwardly-from the surface Ill! and extends into the depression in the under surface of the finger I i] I.

This forms two annular chambers; theforward one of which is occupied by an expansive tube I23 andthe rear one of which is occupied by a The resilient member I25 resilientmember I25. maytake the form of a serpentine spring and it is preferably discontinuous so that it may leng-then when compressed by the expansive action of the tube I23. Normally the finger IIlI is maintained in its retracted inactive position thereofxby the spring I23. Fluid pressure inthetube- I 23 expands the chamber between the flange I2I' andthe projection Ill so as to advance the finger intoan' active position thereof shown in dot dashlines, for example; in Fig.-8. The fluid pressure may be pneumatic or hydraulic and in theexamp1e shown is pneumatic, the air under pressure traveling from the high side 93 of the compressorilsg through the pressure line S,valve IZLthetube 98 and the flexible tube99r Suitable coupling devices l25 may be used-to transmit the pressure to the tube I23. In going to the expansive :tube I24,the air under pressure travels through the flexible tube 99 through the right hand portion of the axle ill, down through the bore9l,outthrough one of the openings 89 and thence via the flexible tube I29.

Because the tube I29 is flexible, sufiicient slack is allowed so that the piston'ilil may reciprocate within the bearings in the strut i33and the Wall 69. The collar l35-in abutting against the inner surface of the wall 6!] acts as a stop for movement of the piston 80 out of the element 41. This motion is of course relative since the expansive spring vI 31 urges the housing 63 away from the axle 91. The head 3i contains the heating means 49 which maybe of any suitable typeas, for exampleran electricalresistance coil I49, The coil 6 I nerite at semirates ea ier and replacement or the plate?

The fiexible element 226 changes its direction about a pulley 228 which is journaled in a support 229 projecting forwardly from the sleeve 203. The upper end of the flexible element 226 is connected to the lower end of a tension spring 235. The opposite end of the spring 230 is connected to a support 23H extending forwardly from the detent 207. The spring 230 is relatively stifi. The flexible element 226 may take the form of a steel cable, or may be a chain. The action of the flexible element 226 is such that starting with the position shown in Fig. l and Fig. 2, as the carriage i999 is lowered by the movement of the toggles 209 and N5, the lower end of the element 22% lying within the groove 232 pulls the half-pulley in a clockwise direction as shown in Fig. 2 so that the element 4'! passes through an intermediate position indicated by the dot dash lines on said figure Continued downward movement of the carriage |99 causes the surface 235 on the housing 53 to contact the surface 234 on the housing 62, This situation occurs before the toggles 229 and 2|!) align so that the last portion of the downward movement of the carriage i99 results in the movement of the piston 89 and the parts connected thereto from the position shown in Fig. 8 to that shown in Figs. 4 and '7. Relief in the tension of the element 226 during this last described movement is provided by the spring 231 accompanied by a compression of the spring Hi.

The control for the valve 38 which may be or the electrically operated solenoid type, is the switch 236, which opens the valve 88 when the plunger and roller thereof are moved to the left as viewed in Fig. 1. This is accomplished by a earn 231 which is moved downwardly by the pedal 59. The valve I21 is also of the electrically operated type and is controlled by the switch 238. Switch 238 is closed by the cam 239. The'pedal 59 is pivotally mounted at the forward end thereof by a hinge 24!] upon the floor 5'5. The cams 23'! and 239 are mounted upon the carrie 2M which is suitably arranged for vertical reciprocation and at the lower end thereof is hingedly connected to the rear end of the pedal 52. The switch 242 is in series with the conductor E83 leading to the switches 236 and 238. The conductors |55 and I56 connect the valves 88 and I2? with the switches 236 and 238, respectively. The lever 2|| carries a cam 223 which acts upon the roller and plunger of the switch 242 to opencircuit said switch when the pedal 6|! is in a rearward position thereof; that is to say, when the housings 62 and 63 have the surfaces 232 and 235 in contact.

Operation In one manner of operation, the motor 244 is connected to the power source 250 by the conductors 249 and the compressor builds up the required pressure and vacuum. The values of pressure and vacuum are regulated in any suitable manner, as by automatic safety valves (not shown) which operate when predetermined levels are reacted. With the parts as seen in Fig. 8, plush blanks or casing elements 22 and 2| are placed upon the guide rings I09 and H0, respectively, a

The casing elements 2| and 22 are placed upon the guide rings H0 and It, respectively, with the pile surfaces down, so that these plush or velour surfaces will be outermost in the finished puff. This operation may be simultaneously performed by the operator using the left hand to place the element 2 l, and the right hand to place the element 22. Next the pad elements 25 and 26 are placed centrally upon the casing elements 2| and 22, respectively. This is indicated by the dot-dash lines on Fig. 2.

Following this, the operator presses down upon the pedal 59. The cam 23? engages the switch 236 which connects the lines 86 and B! with the vacuum line 92. This produces reduced pressure in the chambers ill and H, and the casing elements 2| and 22, as well as the pad elements 25- and 26, are pulled into the position shown in the dash-double-dot lines in Fig. 2. As an alternative, the pedal 59 may have been partially depressed so as to produce the suction before the pad elements 25 and 2B are put into position.

At this stage, the tabs 33 and 32 are substantially perpendicular (see the dot-dash lines in Fig. 13). Continued downward movement of the pedal 59 brings the cam 239 down so that it causes a contact of short duration within the switch 238. This quickly opens and closes the valve l2? so that the tubes I23 and I24 push the fingers NH and H12 into their active positions from which they quickly retreat. The fingers bend the tabs 33 and 3d inwardly an amount sufficient so that they are caught within the flow of air, leaving the die elements 74 and 15 through the air holes 82 through 85, inclusive. This results in the tabs being moved to the position shown in the full line in the Figs. 13 and 14.

Continued downward movement of the pedal 59 results in no change of this general condition; the reduced air pressure within the chambers 10 and it being continued by the length of the cam 231. At this stage, a layer of cement or a ring of thermoplastic cement, such as that indicated by reference character 50 in Fig. 13, is placed upon the then uppermost surface of the tabs 34.

Following this, the pedal 66 is moved rearwardly, and this results in the inversion of the element il, the upper puff half being maintained in position by the relative vacuum in the upper housing 53. Traveling through the dot-dash position of Fig. 2, the element 47 comes to rest so that the surface 235 contacts the surface 234 (see Fig. 8). Continued movement of the pedal til brings the piston 82 down so that the pressure head 8| brings the then upper puff half down into contact with the lower half (see Fig. '7). In this position of the parts, pressure is maintained for a sufiicient period of time and. to a sufilcient degree to assure the adherence of the two pull halves produced by the cement layer. While in this position, the pressure and suction have been cut off by the actuation of the switch 242 which opens the circuit to the valves 88 and i2l. Bleeding of pressure or vacuum may be accomplished in the valves when they are moved to their closed positions, so that the lines 81 and 92 may return to a normal atmospheric pressure in a suitable manner.

The operator may now release pressure from the pedal 59 and following this release pressure from the pedal 65, whereupon the parts will return to their original position of Fig. l and the now integrated put? 25 will lie within the die element 12. From here it may be manually removed 9 and deposited in a suitable container (not shown). If desired, air pressure may be introduced into the chamber 10 (by means not shown) so as to blow the finished product out of the way to prepare the machine for the next cycle.

The production of heat is shown to be accomplished by the heating element I49, and this assists in the drying of the cement or promotes fusion of a heat-activated cement. Where desired, the die 72 may be furnished with similar heat means.

While the die elements 12 and 13 are of circular shape so as to produce a round puff 20, obviously other shapes may be used, such as octagonal, square, or irregular. Because the size of the puff is materially afiected by the size of the dies 12 and 13, the pufis produced are of substantially accurately predetermined size. This offers an improvement in uniformity on prior art products and enables the finished puff to properly fit an accurately sized container or box.

By the substitution of a smaller casing element, such as the casing element Zia, and the omission of the pad element 25, a flat-backed puff, such as that shown in Fig. 14, may be obtained. Similarly, the ribbon 427) may be placed beneath a casing element 21b as the puff 20b is assembled, so as to produce a pull having a handle. Also, by the use of the present machine, the form of puff shown in Fig. 15 may be fabricated.

It may thus be seen that we have disclosed novel and useful powder puff constructions, methods of making the same, and means for such purposes. We wish it to be understood that we do not desire to be limited to the exact details of construction shown and described, for obvious modifications will occur to a person skilled in the art.
