CUTTING MECHANISM FOR PLASTER-BOARD MACHINES.
Application filed June 8,
To all whom it mag concern:
Be it known that I, Lornsx M. RADER, a citizen of the United States, residing at Upper Montclair, in the county of Essex and State of New Jersey, have invented a 1 newand useful Cutting Mechanism for Plaster-Board Machines, of which the followingis a specification.
This invention relates to cutting mechanisms for machines for making plaster upon a machine of this character for which Letters Patent of the United States were granted the present applicant under date of December 29, 1908, No. 907,876.
The primary object of the invention is to produce a transversely disposed cutting mechanism embodying a plurality of rotary cutters actuated in unison and moved toward the plaster board to be cut, and at the end of s "eh cutting operation to be retracted away from such hoard again to be in position for another cutting action.
With the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists in a novel construction and combination of parts of a cutting mechanism for a machine for making plaster boards, as will be hereinafter fully described and claimed.
In the accompanying drawings forming a part of this specification, and in which like. characters of reference indicate correspond-- ing parts: Figure 1 is a view in side elcva tion of a plaster board machine with the present cutting mechanism operably carried thereby. Fig. 2 is a top plan view FiglZB .is a transverse sectional view taken on the line 33 of Fig. 1, and looking in the direction of the arrow thereon. Fig. 1 is a perspective detail view of a short section of laster board produced by the machine.
0 fully illustrate the operationand arrangement of the resent invention, a complete plaster boar machine is shown with v the cutting mechanism in operable relation thereto and comprises a pair of longitudinal beamsl, carried by the uprights 2 which ,are connected at their ends by the cross pieces 3 while the second pair of longitudinal beams 4 are so disposed as to properly support the three transverse shafts 5, 6 and Specification of Letters Patent. I Patented Dec. 31, 1912.
1911. Serial No. 631,965.
7. Upon the shafts 6 and Z are mounted the drums 8 and 9, respectively, whose heads are provided with teeth 10 to engage and drive an endless belt 11, which as shown passes over the rollers 12 carried bya shaft I (not shown) and are journalcd in the longil tudmal beams 1. Motion 1s imparted to the shalts 6 and 7 by pulleys 13 upon the shaft ti and power may be obtained from any suitl able source. This structure is well known and is only here shown and described so that a full understanding of'the present cutting mechanism may be had. Transversely of the machine and above the drum 8 is 1nount ed a hopper l lwhich is designed to contain the fiber F from which the plaster board is made. This cutting mechanism which is the prises a plurality of isk cutters 34, that are mounted upon independent shafts 35, 36, i 37 and 38, each of which carries a pulley 39,
410, 41 and 4-2, respectively, and these pulleys shown, the cutting disks will have a rotary motion at right angles to the travel 01" the belt, and in order to bring these into c0- l operative relation thereto at predetermined 1 intervals,'and at the same time to impart a transverse motion to the series of cutting disks, two two-throw cams 48 are employed, which are mounted upon a transverse shaft 49 journaled in bearings supported by the longitudinal beams 1, the peripheries of which engage with rollers 50 which are carried by independent shafts 51 carried by boxes 52 that are arranged'to slide between vertical guides su ported by longitudinal beams 1, motion being imparted to the earns 48 by a sprocket chain or belt 5-1 that engages a pulley or sprocket wheel 55 on the shaft 49 and a similar member 56 on the shaft 57 of the drum 32, the latter being driven by a sprocket chain or belt 58 driven from the shaft 6. Each of the shafts 51 carries at its outer extremity an arm 59 each carrying a roller 60 that is designed to en gage in a cam groove 61 formed in each of the cams 48.
The shafts 35-38 are carried by a supesscntial part of the )resent invention, com:
As will be understood, by the arrangement moved a sufficient distance to insure the complete severance of the board into lengths,
and when the co-action betweenthe worm and the segments ceases, the support is returned to its normal position by a spring 67, and is thus ready for a repeated operation.
The present machine forms a plaster board which is moved from one end to the other toward the cutting mechanism so that the board is passed beneath the cutting disks or knives 34, and the parts of the machine are so timed, that when a predetermined length of the boardhas passed beneath the disks, one of the interrupted portions of each of the cams 48 will come beneath the rollers 50, whereupon in conjunction with the arms 59 and rollers 60, the support 62 will be forced downward, this being accomplished by the boxes 52 which bear redpeptively upon the worm 65 and upon the other-terminal of the shaft carrying the support 62. This latter motion will bring the worm into engagement with one of theworm segments 66, and will impart a lateral motion to the support, 'causing the disks or knives to make a complete cut of the entire width of the board. By the time that "the worm has reached one end of the segment, the cut will have been completed, and as the segment passes out of engagement with the worm,the springs 64 will return the support to its normal position, while the spring 67 will return the disks laterally to their initial starting point. At the time that the knives are being moved laterally, they are also being rapidly rotated from the motor 47 through the series of belts 4346, effecting thereby a smooth and even out;
I claim:
1. A cutting mechanism, having a frame, a plurality of alined rotary cutters disposed transversely of the frame, means for imparting to all of said cutte s simultaneous reciprocatory and rotary nfovements, and means for timing the operation of the rotary cutters to move to and from the frame at predetermined periods.
2. A cutting mechanism, having a frame, a plurality of rotary disk cutters alined transversely of the frame, and means for rotating said cutters 111dSilnllltttl'lGOLlSlY imparting thereto transverse reciprocatory movement.
3., A cutting mechanism, comprising a frame, a spring returned support disposed for transverse movement of the frame, aplurality of rotatable cutters secured thereto and in alined position, means for rotating said cutters simultaneously, and means coacting with the spring returned support for imparting a reeiprocatory movement transversely of the frame to the support and cutters.
4. A cutting mechanism, comprising a frame, a support capable of transverse reciprocatory movement yieldingly hung from Joutting mechanism, comprising a said frame, a plurality of rotary cutters 4 journaled upon said'support and connected for rotation in unison, a worm gear connected to the support at one end, a spring of spaced toothed segments connected to said shaft to be=rotated to engage the worm gear, "the-segments and Worm and the last spring imparting to the support and cutters a reeiprocatory movement, and cooperative means carried by the power shaft and support for moving the rotary cutters downward when the support is movedby the segments and worm and to move the cutters up- ;.co1111ected at the other end of the support "and frame to operate the support in opposition to the worm gear, a power shaft,'-a pair wardly when the support is returned said A last spring. 6, A cutting mechanism, comprising a frame, a transverse support c rried thereby, V a plurality of alined rotary cutters disposed below said support, a plurality of springs for normally holding said cutters upward and away from the frame, means for im-' parting a rotary movement to all of said cutters, means for imparting a reciprocatory movement to all of said cutters during the rotation thereof, and means for moving said cutters against the tension of the springs, and into cutting posltion.
