Description

a proper number of intake valves and exhaust valves (not shown) are provided. Instead, however, of operating said valves by means of push rods and rocker arms, said valves are operated in the desired timed relation by overhead camshafts 25 and 26. These cam shafts,.two for each cylinder group, are disposed in parallelism and have an over-all length suflicient to span the total number of cylinders comprised in each cylinder group. In Fig. 3 it will be noted that the cam shafts 25 and 26 are mounted in suitable bearings 27 fastened to cylinder head cover plates 28 which are in turn fastened to the cylinder heads. Said cover plates 28 are preferably of one piece construction and are adapted to bridge the space between the cylinders of the respective groups and at the forward end of said groups are adapted to overhang the group series to provide housings 29 within which suitable gearing 30 for the cam shafts is enclosed. Cover plates thus characterized reinforce the cylinders of each cylinder group and at the same time provide an-adequate at: tachment surface to which the cam shaft housings 31 are fastened. A valve gear of the character herein disclosed is essential. At speeds exceeding 2000 RP. M. push rods and rocker arms, due to inertia forces, are incapable of continued operation for periods of long duration.

The means for driving the cam shafts 25 and 26 (in addition to the gearing 30) comprises a plurality of radially arranged drive shafts 32 which, at their outer ends, enter the cover plate overhangs. Said shafts 32 at their inner ends are carried into the crank case 10, each shaft having mounted on said inner end a bevel gear 33 which meshes with a similar gear 34 mounted on the engine crank shaft. Each said drive shaft is operated at the desired speed of rotation, due to its geared connection with the crank shaft,

and in its relation to the cylinder group which it serves, extends radially out from the crank shaft in line with the radial plane of its associated cylinder group.

As is customary in aeronautical internal combustion engines, a certain number of engine accessories are essential to the proper operation of the engine herein described. Such accessories include a carburetor 35, a fuel pump 36, an oil pump assembly 37, two distributors 3838, a magneto 39, an engine starter 40, and a generator 41. Preferably such accessories are grouped radially aboutan extension .42 of the crank case 10 so that any or all of such accessories may be removed or replaced with as little inconvenience as possible. The crank case extension 42 is fastened to and against a rear end blower or compressor 43, the latter, as indicated in Fig. 4,. being directly fastened to the rear end of the crank case. directly driven off the crank shaft 12, is so Said blower 43, which isv formed and constructed as to providewithin the crank case extension 42 a fuel induction passage 44. This passage 44is open at one end to the carburetor 35 and at its opposite end widens outwardly to form the casing within which the blower 43 is enclosed. From said blower casing the fuel mixture is fed radially to the cylinder intake ports 22 thru the intake manifolds 24'.

In addition to driving the blower 43, the crank shaft 12, thru its rear end driving terminal 14,- is directly geared as at 45 to a counter-shaft 46." This counter-shaft 46 has an axis of rotation parallel with the axis of rotation of the crank shaft tho it is enclosed ter-shaft 46 and directly driven off the worm ear 47 there is provided a vertical shaft 49.

k aid vertical shafts 49, which extend parallel, are journaled at their opposite ends in bearings 50, and at one end are extended beyond the underside of the crank case extension wall. One of said shafts has mounted at its extended end the fuel pump 36,whereas the other of said shafts is still further extended to drive the oil pump assembly 37 said pumps 36 and 37 like the carburetor 35, being fastened exteriorly of the crank case extension on the underside of its bottom wall. As illustrated in Fig. 5, the shafts 49 are located one each at opposite sides of the fuel induction passage 44. Transversely extendingstub shafts 51-51, geared as at 52, one each to each vertical shaft 49, extend laterally out from the fuel induction passage 44 to drive the distributors 38 which are mounted exteriorly of and against the opposite side walls of the crank case extension 42.

The magneto 39 and the engine starter 40 are also mounted exteriorly of and against the opposite side walls of said crank case extension. The driving connection for said accessories 39 and 40 consists of a transverse shaft 53 having a bevel gear. 54 mounted thereon and meshing with the bevel. gear 48 mounted on the end of the shaft. Said accessories 39 and 40, however, are disposedin a horizontal plane above the corresponding plane of the shafts 51 and in a transverse vertical plane longitudinally removed from the transverse vertical plane of the vertical shafts 49. Moreover, if desired, by the provision of a vertical stub shaft and bevel gear (not shown) the generator 41 may be likewise driven olf the bevel gear 48. Preferably said generator 41 is mounted on the exterior top side of the crank case extension 42.

B0lts 55, grouped radially about the crank case extension, and carried by the blower casing, provide an appropr; ate mounting an iv May 31, 1932.

-This invention relates to improvements in dispensing apparatus andhas particular refere-nee to a machine of the type wherein a continuous web of paper is 'fed to 'a cutter to be severed thereby into predetermined lengths. l

An object of-the invention is to provide an improved machine of practical construction in which a continuous web of-paper is fed to' acutter which .is operated, by the means which feeds the paper thereto,-'to sever said web into predetermined lengths.

Another object is to provide the machine with two web-feeding devices so that difierent predetermined lengths ofpaper may be fed to a cutter, either of said devices being effective to control the operation of said cutter. The above and otherobjects will appear more clearly from the following detailed de scription, when taken'in connection with the accompanying drawings, which illustrate a preferred embodiment/of, the inventive-idea.-

' Thepresent machine is especially designed for dispensing parchment paper or the like,

' such as used in stores for providing inner wrappers for foodproducts, but it is to be expressly understood that the machine is not limited to such use, the scopeof the invention being defined by the appended claims "The machine comprises a casing'10 having a removable cover l1 and front and rear walls 12 and"13., Mounted upon the side walls 14adjacentthe rear of; the casing are 7 opposed brackets .15 vertically slotted, as in dicated in, dotted lines in Figure 2, to re ceive the ends of a free-floating shaft 16j which carries-the continuous web of paper ,17- infthe form of a-rollwhich rests'ujpon th'ebottom of-the casing at all times as'the 1 diameter of 'the'roll decreases. The web-of paper'is' fed'on to a guide in the nature of a platform 18'supported-within the casing. longitudinallythereof and having its i'e'ar, end disposed directly above the roll of pa er: The platform '18 extends to a point adjacent the front Wall 12 of the casing which is provide'd with an" outlet 19 through whi'chj'sev cred sheets are withdrawn'from thecasing,

and the forward portion 20 of said-platform: is inclined downwardly for purpose which will appear'in the-course of the description. In order to properly guidethewebof paper,

- the longitudinal edges of the platform are doubled upon themselves to pr0vide overhanging fianges21 whichforni channels for 78 receivingthelongitudinal edges of-saidjweb; Substantially coextensive withthe platform 18 andalong the longitudinal edges thereof there are supported tracks 22 and 28, the entire lengthof each of which is-in thesame plane so that the forward end of the track" will be elevated above the inclined portion 20 'ofthe platform. Y 7

In the track 22 there is mounted fol-slid; ingmovement longitudinally thereof a feeder generally indicated by the numeral24, while in the track 23' a similarly constructed feeder 25 is mounted-for'sliding movement. 7 Thesei feeders are alternatively used for f feeding different lengths ofthe web 17 along'the 90 platform '21 to a cutter to be later described and, "for'this purposeysaid feeders-are dis posed in normal positions at difi'erentj disk tances from the forward" end of said platform,so=that the movement of either feeder along its track to a point-contiguous to. the" rear end of the inclination 20 of the platform will advance a different length of the web; 17 to the cutter thanthat which is advanced by the other feeder. i I

. determined length of the web.

,Each feeder comprises a shoe 26 slidable I in its track and having an. operating lever 27 pivotally connected thereto and projecting through a longitudinal slot 28 formed in the.

cover 11 with its outer end adapted to be grasped in a hand of t-he'operator when it is desired to obtain a severed sheet from'the machine. Extending inwardly from the lever 27 of each feeder and overhanging the platform 18, is an arm 29,the inner end of which has secured thereto a gripper member '30 of rubber or any othersuitable mate rial which, in the normal position ofthe lever 27, is slightly raised above theweb v17, but. which'is adapted to engage said web when the lever: is thrown rearwardly about its pivot, which is the initial operation'preparatory to advancing the w-eb toward the cutter.

'Wherithe lever is thus operated, a-coil spring 31 connecting the same with its shoe 26. is compressedso that, upon release of the lever by the operator at the conclusion of theop; f eratiQH', said lever is restored to. its normal, position and the gripper again disengaged from the web. In its normal jposition the feeder is prevented from rearward movement alongits track by a stop member; 32 in .the form of a wire or small rod having its ends bent for insertion into any one of a seriesof opposed pairs of openings 33 in thetrack of the feeder; This stop member is adjustable to any positionalong the track so as to vary the normal position of the feeder, whereby thesamemay be caused to advance any .pre-

Means are provided in; connection with each feeder for restoring the same toits nor-.,

mal position against its stop me'mber32, followlng ts forward movement along the track thereof and the release of the lever 27 by the operator. This means comprises a flex-s ible band or tape 34, one end offwhich is conected to the shoe 26 of its respective feeder-, sa d band extending rearwardly from said shoe and over an idler 35 at therear end;

of the feeder track. From this idler the band extends, to admin 36 mountedupon the base of'the casing 10 and upon which said band' is wound. A spring 37 is ,coiled within'the drum and its outer extremity connected thereto, while the inner end there of issecured upon a shaft 38 projecting from said drum. 1 This shaft has associated there:

with an escapement mechanism includingthe '3 ratchet39 and pawl 40 which ceoperate to holdthe shaft and maintain the spring 37 7 under; tension. By turningtheje'nd of the,

projecting shaft 38? in a clockwise direction, as: viewed in Figure 2, theftfcnsion 'of the ,1 spring 37 maybe increased and, by tripping the, pawl 40 to. permit of stepf-by-steprota-v V tion of the shaft 38, in an opposite. direction,

said tension may be decreased. 'It. will thus be; seenthat, when one of the feeders is pulled 6.5 forwardly by the operatoraf te'r thelever 275 of the feeder has been swung rearwardly to engage the gripper member30 with the web of paper,the latter will be advanced and at the same time the band 34 will be unwound 1 from the drum. 36, thereby putting the spring 37 under the tension necessary to automatically return the feeder to its-normal position when the lever 27 has been released. 7

As either feeder is drawn forward, during which the lever 27 thereof held the operator in its rearward position, the gripper member 30 continues to engage theweb 17 until the" rear end of the inclined portion 20. of the platform reached. Then, as the guide flanges 21 and at the point of emer gence of the web therefrom a, stationary cutter bar 41, to one end of which. there is pivk 'oted, as at '42, the movable cutter 43 which,"

in its normal position, is raised above the platform and; yieldably held in such position by 'a retract-ileispring 44, one end'of which is connected to the free end, of said cutter and the other end of said springis joined to the upper end of a standard 45secured to I p the base ofthe casing (Figures 3. and 5-). Alsoconnected to the free. end of the. cutter 43 is one end of a -link 46, .the other endof which is joined toa lever 47. pivoted, i i-ten mediate its ends as at 48;, toa standard: 49 also supported upon thebase, o-fthe casing 10. The other end of the lever 47 engages a. tripi50 in the form, ofa. bell-crank, pivoted to said standard 49 andhavingonezend; pro.- jectinginto. the. track 23.0.f the feeder 2' 5Qso as to be contacted'by the shoe '26; of said feederflas the latter approaches the-endfof its forward movement, said :Inovement being; limited by a stop member. 51 similar to the, members 32', Upon contact-of the shoe 26 with the trip '50v the latter is. rocked abou its.

pivot and,.' inso doing, imparts a similar movement to vthe. lever4-7,throwingthe front end thereof downwardly pulling "the; cutter 43 therewith. sogthatthe latter will-1cooperate with the cutterbar 41to sever the desired n th Of rare r m. t e We the major portion of which lengthis at; this timeprojected through the opening 1 9 and.

can fol lowin-g its severance. from the; W.ebV-,' be thdr wn r m smeshme rd to. producea shearing action between the bar 41 and cutter, 43;, the latteigin its no mal posi;

tion, ext ndsze igh -aneler la ire be? the vertical plane of the bar 41 so as to partially overhang said bar, as best indicated in Figure 1. The cutter is yieldably maintained in this position by a leaf-spring'52, the lower end of which is secured to the standard 45 while the upper portion of the spring engages the free end of the cutter 48 and forces the same rearwardlyso as to position it diagonally, as previously mentioned. The ten sion of the spring 52, and consequentlythe amount of its lateral pressure against the bar 41 as thecutter is operated, may be regulated by a set-screw 53 mounted on the standard 45'and engaged with said spring. Upon. release of the lever 27 from its position in' Figure the same is thrownforwardly by its spring 31 and simultaneously the'spring 1 37 of the winding drum, which is at this time under tension, operates to wind the band 3 L upon said drum and thus pull the feeder 26 rearwardly until it contacts its associated stop member 32. At the same time the spring 44 of the cutter 4E3 acts to restore the to its normal position. The operation of severing a latter the opposite side of the platform 18:.from the feeder wilf now be described The web 17 is advanced in-the same manner as previously described to the cutting pomt,

whereupon the continued advancement of the feeder 24 causes its shoe 26 to contact the end of the bell-'crank'lever 54: which prov jects into the track 22. Said lever- 54 is similar to the trip and is pivotally mounted upon the standard 55, with its other end in engagement with the rocking lever 56 cor-l responding to the lever 47. The forward end of the lever 56 is connected by a link 57 to the free end of a cutter-actuating arm 58, the othere'nd of which is pivotally con nected to the'standard 45. Intermediate the ends of this arm a pin 59projectstherefrom and rests upon the upper edge of thescutter With this construction, when the shoe 26 of the feeder 24 rocks the bell-crank lever 54 about its pivot, the lever 56 is operated to pull down upon the link 57 and thereby cause the arm 58 to eXert'a downward pressure upon the cutter which then cooperates with the bar 41 to sever the web. Release of the lever 27 of the feeder 24 then permits the latter to be restored to its normal position in the same manner as described in connection a. with the feeder 25. w
