Claims.
This invention" relates generally to machines for bursting perforated forms so as to separate such forms along their lines of perforations into individual sheets; and more specifically to a machine of this typewhic'h is of such improved construction and arrangement that it is capable of performing its intended 'functionin an improved and highly efficient manner, the predominant object of'the' invention being to provide a machine for' bursting perforated forms which is extremely simple in construction and which is capable of efiicientoperation at high speeds; v
Fig. 1 is a front elevational viewof the im proved machine'- of this invention.
Fig. 2 is a vertical sectiontakenion'line2-2 of Fig. 1.
In the drawing; whereinis shown for purposes of" illustration, merely; one embodiment of the invention, A designates the improved machine generally. The machine-A includes as a part of its mechanical structure a base plate I from which is extended upwardly a pair of spaced, side plates 2. Byreferringjto Fig; 1' it'will be noted thatopposite"end-portions m of the base plate I projectoutwardly-beyond the spaced, side plates 2, and, as is indicated-in Fig. 2, portions.
opposite ends'withreduced'portions which serve as trunnions 3' and 4', these trunnions being supported in" bearing openings formed in the spaced, side plates [so-as to" support "said rollers 3"and 4 for'rotary movement. The rollers 3 and and 4'- are spaced-apart; as is shown in Fig; 2,.
and disposed between sai'd rollers is a'bar 5 which is fixedly'supportedby the spaced, side plates 2, said bar beingprovided with a curved tooface 6 which servesa function 'to'be' here-- inafter' set forth.
The spaced; side-plates 2; support; also; a roller 1 which is located "at. the rear; or form-entering endof the machineA, this roller "having reduced portions 1" atiits opposite ends that serves as trunnions and which are supported in. bearing openings formed in thetspa'ced, side, plates 2 whereby the roller 1' is' su'pported by said side plates'for rotary movement; Additionally, the
machine A is providedwitliz azguide' member 8' which is formed from suitable material, sheet 13y referring particularly to Fig, 2 itmetal, for instance, and which includes a curved portion Be that embracesthe' forward'portion of the roller 7, as'is shown to good advantage in Fig. 2, said curved" portion 8a of saidguide memher 8 being spacedslightly fioin'the peripheral face of the roller 1.' The' curvedportion 821 of the guide member a merges into a-curved portion 81) which in turn merges inte an upwardlyand forwardly inclined portion 8c which terminates immediately adjacent: to" a: rear portion of the head II is pivotedto the spaced, sideplates- 2 by means ofbolt/e312. whichare provided-with heads lZa whicharerdisposedioutwardly of the arms Ha, andscrewthreaded shanhportions I2b that are screwthreadedlyseated in screw-threaded openings formed in theespa'eedz side--plates--2; said-w bolts [2 beingprov-idedxw-ith smooth, intermedi ate" portions 1 I 20- which are disposedin openings formed in thearms'llwof theehead I 1.
terial, said roller- 13 preferably,-
spaced, circumferential: ribs I4. The-roller.- I3' is mounted ona shaft [5 which isprovidediwith reduced portions. I5a;at its.opposite ends, these I3 is siorced into, close... contacting engagement with the. rollers Band .4 .by. a pair..of-head adjusting elements l fijwhichhomprise rods whosellower. end portions. aresorewthreadediand are received. in screwthreaded openings. ll formed in the base.
plate I. The head ill ofjthe machine A is provided. with outwardly projected. extensions, l8
having openingsformed therethrough, through which upper portions ofJtherodsof the head adjusting elements l6"extend',.there beinghead'portions I9 at the upper ends of" said rods which engage the top faces of said extensions I8. By rotating the head adjusting elements It in the appropriate direction the forward portion of the head ll of the machine is moved downwardly so as to force the roller l3 into tight engagement with the rollers 3 and 4, sufficient pressure being exerted by said roller l3 against the rollers 3 and 4 to cause a part of the resilient roller Hi to bulge downwardly between the upper portions of said rollers 3 and 4, as is indicated at 20 in Fig. 2.
The trunnions 4' of the roller 4 at one side of the machine A has fixedly mounted thereon a suitable pulley 2|. This pulley receives a power transmission belt (not shown) by which power is transmitted from a suitable source of power (not shown) to said roller 4 for rotating said roller 4 and the rollers 3 and [3.
