I Referring more particularly to the drawings; is a table which .ismounted on a shaft 2 having a step bearing 3. The shaft 2 also'"has a bearing 4. in a supporting cast? mg or bracket 5. Mounted on the shaft 2 intermediate the hub of the table 1 and the bearing 'is a spider 6 which is connected to the under face'of the table 1 by means of bolts '7, so that the two rotate together. Powerfor armin the spider 6' is obtained from the shaft 7 which is driivenby a belt wheel -7",' or anyfothersuitable means. On the inner end of the shaft 7 is a gear 8 which meshes With agear9 which is carried by a shaftl'O. ShaftjlO is provided with four bearings, one in the-block 11, one in the casting, 12 and two others in the blocksld --.and 14, respectively; Mounted atone. side of the block 13 is.a bevel gear' l5 which meshes withta gear 16 on a shaft 17. Shaft 17 is vertical and is carried in two bearings supported by the casting 12. At the upper end of the shaftli'fisthe member 18 which gives to the spider 6 and the table 'la peculiar step by step movement. One end of the member, 18 is. i i-"the form of Hank which carries an upwardly projecting pin 19, on which is mounte d'a revolube spool. orroller 20. Theotherfpart of tlieinember18 isiin the form of ajsemi-circular disk or cam 21' which lies in a' lower plane than: the roller 20, as clearlyshown in Fig. 11.

The exterior edge of the spider fi is provided with two sets of surfaces, one for coeperat IIIg'WIth the roller 20 and the other for cooperating with the disk 21. The surfaces which cooperate with the roller 20 are in the form ofiteeth 22 which lietin the same plane as theroller 20 andare separated by recesses slightly widerthan the diameter of the roller On a lower plane than the teeth 22 and- 20. on the samelevel with the disk 21', theedge of the spider 6' is provided with a series of I earn surfaces, 23 shown in plan partly in dotted lines in Fig. 12. Thesecam surfaces are arcs ofkcircles whose radii correspon to the radius of the exterior edge of the disk 21, the points of intersection between the surfaces 23 being intermediate the teeth 22. Now it will be understood that the shaft 17 is rotated continuously by the connections previously described with the shaft 7, but

' that while tlie'diskl21 remains in engage spider 6 and consequently the table lis held ment with a particular. cam surface 23, the

firmly in stationary position. Hdwever, as thedisk21 passesout of engagement with -its cooperating, cam surface the roller engages one of theteeth 22 giving the spider 1 and table a positive movement i'n the direction ofthe arrow.

The table 1 is provided with a shoulder 24 which causes the exterior surface of. the

table to act asla shelf upon which may be placed tins 25 to'be used for baking. cup

cakes. Intermediate two adjacent tins are provided upstanding ridges ,or webs 26 which are each provided with a lug 27 for holding'the tins securely to the table while the machine is in operation.

' Carried by a standard such as 28 is astationary cover plate or apron 29 which covers "a little more than half of the surface of the revolving'tins, and upon which is mounted the cutting and feeding mechanism herein- 'At the outer end ofthe shaft 10 is a gear wheel 30 which meshes with a gear "31 on the shaft 32. At the end of the shaft 32 opposite from the gear 31 is a crank arm 33 which is provided with a slot 34 which provides an adjustable connection with the-link or rod 35. The rod 35 is connected at.its

upper end to, a lever 36 which is loosely mounted on the shaft 37. Since the member- 33 rotates continuously the upper end of the rod 35 and consequently the lever arm 36 is oscillated about the. center of shaft .37. The lever .ttiIIl 36 carries 3 a pawl 38 shown. in

dotted lines in Fig.2 which engages with the teeth of a ratchet"='wheel 39. Conse ,;quently" as the} lever 36 oscillates it gives a step by step movement, to the shaft 37 by ,lnieans of thepawl' and ratchet. Mouiite'd on.

the shaft 37 are two drums or wheels 40 and'4l for-"driv ng: the paper webs. 42 and 4'3 from which the pieces are eut'whi'ch are placed in'the' tins. Mountd immediately 7 below the drums'40,and"41 respectiyely- iare drums 44 and 45, the web 3142 'b'eing; led,

around the outer surface of ,the'druing40. and

' in between'drums 40' and 44 wliileth "web 43'islled aroundthe outer surface" of the drum 41 and in between the "drumsj41 and 45. The uper'part of th'e drum 41 being below the evel of the'table the web 43 is guided. on to the drum 41 by means of the roller 46. It will be understood moreover that the drums 44 and 45 are suspended below drums 40 and 41 by meansof'brackets 47-47. The shaft" .37 being positively driven, the drums 40 and 41' inconnection with 44 and'45 serige to feed the paper webs positively. The webs 42 and 43 are carried by separate rollers 4848 which are mounted on a shaft 49, carried in brackets 5050 mounted on the upper face of the plate 29. The webs 42 and 43-are also guided by the rolls 5151'. In order to prevent the webs 42 and 43 from feeding too freely I provide friction rollers'52-52 which are carried by a shaft 53 which is pivotally mounted in the brackets 50 50., If desired the shaft 53 may be thrown up into'the dotted. position shown in Fig. 2 so as to permit the ready removal orreplacement of the webs 4243.

The brackets 50 are-provided with extensions 5454 against Which the arms 55-55 which support the shaft 53 may. rest when the rolls 52-are lifted. After leaving rollers i 51 the webs 42 and 43 run hO-rizontallyuntil they reach the drum 40 and the roll .46 respectively. In passing through this horizontal stretch the webs. are cut to provide pieces for lining the tins and the cut pieces are placed automatically in the tins, Asshown in Figs. 1 and 2 the tins have a radial depth of three cups or recessesf Consequently I provide three cutters 56, 57 and 58. I'Owing that of the top of the tins; Consequently.

the outer edges of t he cutters overlap the to the fact that the pieces of paper are cut outer edges of the recesses in the tins and. I

.all three-of the putters can not-be placed in a row radially of the tab'leybut one is oflset from the other two, as plainlyshown in Fig.

1. The detailflof the? cutter mechanism is shown in Figs 7, 8 and 9, the cutter 57 being selected for detailed illustration. Each cutting mechanism comprises a stationary and a reciprocating part, the stationary part be ing carried on the upper face of the plate 29 and comprising anupstanding cylindrical knife plate 59 which has a sharp circular knife edge at its phe ixed knife 59 iheld in position by annular plates 60, plates -60 being attached to the face oftheplate 29 by screws 61, and each extending approximately 90 degrees are. Plates 60 form a central aperture. through which the pieces of "paper 62 shown Fig. 7 maybe placed in [the tins after being cut from the. web. At-

tached to theinner face of the knife 59 and ,held between two adjoining plates 60 areffour radial knives 63 placed 90 degrees apart around the plate 59, 'and extendingto the edge -of the aperture '64 in the plate 29.

Above the knife 59 is a reciprocating knife 5 which is also cylindrical in form but has its cutting edge at the bottom, the knife" 65 mating with the knife 59on the inside. -The" knife 65 also carries radially placed knives 66, which are mounted between ridges 67-67 on the interior face of the part 68, and are also held in place by two, sets of screws as shown in Fig. 7. The radial knives 66 cotins the edges of the slits may overlap each other and allow the papersto be forced into the tins without wrinkling. One of the papers 62 having the slits cut therein is shown in Fig. 13. l

The part 68 is mounted at the end of a tubular sleeve 69 which slides in a bearing movement between the two.

in the bracket 70. and is operated by being attached to a yoke plate 1. -Mounted to slidewvithin the sleeve 69 is a rod 7 2 'at the lower end of which is mounted the mecha nism for placing the papers 62 in the tiny after the papers have been cut from the web. This mechanism consists of a stamping member or head 73 which is attached to a stud or shank 74. The end ofthe rod 72 is drilled out to receive the shank 74 and the rod 72 is also slotted as at 7 4 to receive a pin 75 for retaining the shank within'the end of the rod and for allowing 'a certain relative The shank 74 does not fit closely in its bore, so that head '73 is allowed play in both the vertical and horizontal directions. A spring 76 normally forces the head 73 outwardly so that the-pin lleS at the lower .end of the slot, but when the head comes in contact with the interior of the tins the spring 76 may be compressed,

thus avoiding pounding on the tins, but insuring that the paper shall be firmly placed in position.

The cutting mechanism and the stamping mechanism justdescribed are operated from two .cam grooves formed in opposite faces of the cam plate 77 which is mounted on the shaftlO between the blocks'13and 14. Cam rollers mounted in these grooves operate rods 78 and 79 respectively. One of these rollers 86 is shown in dotted lines in Fig. 3,

being hidden by the gear 30 and the member 87. These rollers are mounted on the plates 87 and 88, the supporting nuts being shown in Fig. 2. It will be understood that the plates 87 and 88 are forkedand embrace the shaft 10 on each side, so as to avoid the necessity of a fixed bearing'and an additional link at the upper end of the rods 78 and 79. The rod 78 connects at its upper end with a pivoted lever 80, as best shown in Fig. 3. This lever 80 is pivoted to a casting 81 which is mounted on top of' a bridge shaped casting'82 in which are the bearings for the tubes 69 and rods 72 previously mentioned. At the end of the lever opposite the operating rod 78, the lever con- 'nects with the shaft 89 which is pivoted in i lever' in turn with the pivoted shaft 89, also pivoted in the castings '81 and 81% The shaft 89" carries, a lever 83 which is connected at its outer end to a short link 84 pivoted in turn with the-plate 85,, to which are connected the rods72 for operating the heads 73. 7 It will be understood that the grooves in the cam plate 77 are so cut that. the rod 78' will first be operated to cut one of the. pieces 62 from the webs and that the rod 79 will next be operated to force the piece down into the tin. Owing to the [fact/that the cuttingmechanism 56 is in a different radial plane from cutters 57 and 58, it follows that in order to "avoid an unnecessary waste of paper the cutter 56 is provided with a separate web of paper from the cutters 57 and 58. This arrangement has been previously described, but it follows from this that the web 43 which cotiperates with the'single cutter 56 should be fed only half as fast as the web 42 which serves the cutters 57 and 58. This difference in speed of travel between the two webs isprovided' for by tlie different d-iam-. eters of the driving in drums-40 and 41.

Carried on the plate 29, in a different radial position from the cutting and stamping mechanism, is a feeding mechanism for. placing a-proper amount of dough in each tin. This mechanism comprises a hopper 90 which appears in Figs. 1. 2 and 3, and is shown in detail'in Fig. 4. Atthe bottom :of the hopper are mounted three sets of feeding. mechanism which are mounted below a plate or member 91 having apertures therein, through which the dough feeds, these apertures being separated by ridges 91. The hopper 90 is bolted directly to plate 91 by whi ch it is supported. Immediately below the member 91 is a revoluble member 92 which is formed with gear teeth 93 on its outer surface. Each of the members 92 provided with a central aperture, to the inner surface of which is attached a feeding worm or screw '93 so that the worm. turns with the member 92. The members 92 are mounted to revolve in bearings 94 supported tubes 97-97, into which the worms 93. de-

pend. Below the mouths of the tubes 97 is mounted cut-off mechanism especiall illus trat'ed in Figs. 5 and6. This cutoff mecha- 95. The plate 98 'is provided with elongated apertures 10110l, through whieh the dough delivered by the worms 93 may drop into the tins Qn the under face of the plate 98 are cutting plates 102-102, which are- 5 ,slott'edas shown at 103, so that they may be adjusted on the plate 98 to vary the size of the aperturelOl, and consequently the point at which. they cut off the dough from a given tin, thus regulating the amount ofdough in 29 the tins. Plates 102 are provided with crescent shaped cutting edges 104-104, a shown in Fig. 6. q I The; feeding'lnechanismv is operated 'from the shaft 7 'by the gear wheel 105 which meshes With'a. gear 106 \vhich'drives a shaft the table 1 and an empty tin inserted in its place without the .necessity for stopping the machine.

It will be understood by those skilled in mechanical arts that while Ihave shown and described'the preferred form of my device,

that various rearrangements. and modifications thereof may be made without departing from the splrit .of my invention. For instance instead of a circular revolving table I may use an endless belt or'conveyer for carrying the tins, and mount the cutting, stampinggand feeding mechanism above such conveyer instead of above the table shown. Consequently it will be understood that I contemplate all modificatio sland rearrangements which are mechanicifll the device shown and described herein.

Having thus described my invention, what Iclaimisf:"- g,

1. The combination of a movable device for carrying baking tins,- mechanism-for lining s'aid tins with paper, means for placing dough on said paper, and meansfor moving said device. v

107 at the upper endof which is a gear 108. 2. The combination of a movable device :Ihe teeth of, the gear 108 mesh with the, teeth 93 on the outer surface of one of the members 92, and as the teeth 93 of all the "Ine'mber 92' mesh with each other, the gear 108 drives them all in unison. The plate 98, however, is operated from the cam 109, also carried on the shaft 7, and shown in detail in Fig. 10. The cam 109 drives a lever 110 a v which operatesa rod 111. Rod-.111 connects at its upper end to a lever 112,,whichconnects with a shaft'120 pivoted at the upper end to castings 113 Shaft 120 carries two lever arms 112 which are connected by short 49f links 113, to the plate 98 in order to recipro .cate' the plate.

' In the operation of understood that the table 1 carrying the-cake tins 25, is given a step by step movement by .n means of the mechanism heretofore described in which there is a perceptible pause between each forward movement or step of thertable. While the table 1 isstationary .between the sucees'sive steps, the "cutting 50 mechanism cuts the pieces 62 from the webs 42 and, 43, and thestamping me'chanism "places the pieces of paper in the tins As the table is stepped around tins containing papers are brought under. the dough feeding mechanism whereupon during one .of .the stationaryrperiods the plate 98 is operated by the link motion connected thereto to present apertures 101 beneath the tubes. 97 whereupon the worms 93 deliver a charge or dough into the tins. Upon the return stroke .Qo-f the'plate 98 the dough is cut off and immediatelv thereafter the table is moved forward a step and the operation just described is repeated. When a given tin has been completely filled with dough it is removed from dough on said paper, and means for 'm device it will be for carrying baking tins, mechanism for lining said'tins with. paper, means for placing giving said device a step bv step movement.
