1 Claim. (Cl. 83-155) The present invention relates to a machine for destroying magazines and it consists in the combinations, constructions and arrangements of parts herein described and claimed.
Generally there is provided a machine for destroying magazines and the like so that they may not be re-sold. The machine generally consists of a frame inthe forward upper end of which is provided a hopper having a vertically adjustable vertically extending rear wall and the bottom of which consists of a plurality of transversely extending parallel supporting rollers which extend outwardly and downwardly to a feed roll which likewise extends transversely in a position subjacent the adjustable wall of the hopper. Rearwardly of the feed roller is a pair of transversely extending vertically spaced shafts each carrying a circular cutting knife. The knives cooperate to sever magazines fed thereto by the feed roller. A pair of longitudinally extending endless belts is arranged in the frame to receive the severed portions of the magazines and deliver them rearwardly. A motor and suitable drive means are provided in the frame to complete the machine.
It is accordingly an object of the invention to provide a novel machine for the severing of magazines and the like.
Still another object of the invention is to provide a machine of the character set forth which is simple in construction, inexpensive to manufacture and yet effective and efficient in use.
A further object of the invention is to provide, in a machine of the character set forth, a novel hopper forming a part of the invention.
A still further object of the invention is to provide, in a machine of the character set forth, novel feeding means forming a part of the invention.
Other and further objects of the invention will become apparent from a reading of the following specification taken in conjunction with the drawings, in which:
Figure l is a side elevational view of an embodiment of the invention,
Figure 2 is an enlarged plan view of the machine illustrated in Figure 1,
Figure 3 is a fragmentary vertical sectional view of Figure 2,v
Figure 4 is an enlarged fragmentary rear elevational view of Figure 3,
Figure 5 is a sectional view taken substantially along line 5-5 of Figure 3,
Figure 6 is a further enlarged fragmentary sectional view, partly broken away, illustrating a feed roll forming a part of the invention, and
Figure 7 is a still further enlarged view taken substantially along line 77 of Figure 6.
Referring more particularly to the drawings, there is shown therein a machine for severing magazines and the like comprising a frame having a plurality of vertical standards 10 carrying a platform 11 adjacent the lower ends thereof. A bracket 12 is affixed to one of the stand- States atent O Patented Feb. 28, 1961 ards 10 and has pivoted thereto, as indicated at 13, a shelf 14 for an electric motor 15. The outer end of the shelf is adjustably connected, as indicated at 16, to a vertical shaft 17 mounted upon the platform 11.
Mounted atop the standards 10 is a pair of side walls 18. A rear wall 19 interconnects the rearward edges of the side walls 18 and a top wall 20 extends forwardly for a distance of less than one-half of the length of the side walls 18. Forwardly extending from the top wall is a horizontal bracket 21 in which is pivotally mounted a vertical shaft 22 having an operating handle 23 at its upper end. The lower end portion of the shaft 22 extends slidably through a guide member 24 carried upon the rear face of a vertically extending hopper wall 25. The shaft 22 is threadably engaged in a dog 26 likewise carried upon the rearward face of the hopper wall 25.
The hopper is generally designated at 27 and consists of the forward portions of the side walls 18 and the vertically movable and adjustable rear hopper wall 25.
A supporting shelf 28 is afiixed by means of a bracket 29 to the forward edges of the side walls 18 and a plurality of supporting rollers 30 is rotatably mounted and extends transversely between the side walls 18. The supporting rolls 30 extend downwardly and rearwardly in an inclined plane, the foremost of such rollers having its upper peripheral edge in substantially the same plane as the upper face of the supporting shelf 28.
Transversely and rotatably mounted in bearings 31 formed integrally with the side walls 18 is a feed roller 32 provided with a plurality of rows of circumferentially spaced teeth 33.
Transversely extending between the walls 18 forwardly of and below the feed roller 32 is a shaft 34 and transversely mounted in a bridge member 35 is a shaft 36 which is horizontally adjustable in the bridge 35 by means of blocks 37 and screws 38. A pair of transversely spaced horizontally extending parallel belts 39 is mounted upon pairs of rollers 40 and 41, respectively, carried by the shafts 34 and 36.
The motor 15 is provided with a pulley 40 which is connected by a belt 41 to a relatively large pulley 42 carried by a transverse shaft 43 mounted in the frame. The feed roller 32 is mounted on a shaft 44 whose outer end is provided with a cog 45 which is connected by means of a chain 46 to a cog 47 carried at the adjacent end of the shaft 43.
A cog 48 is mounted on the shaft 43 adjacent the cog 47 and a chain 49 interconnects the same with a cog 50 mounted on the adjacent end of the shaft 34.
Upper and lower cutter'shafts 51 and 52, respectively, are transversely mounted in the frame and are respectively provided with intermeshing cogs 53 and 54. The shaft 52 has an extension upon which is mounted a cog 55 which is connected by a chain 56 to a cog 57 carried by the shaft 43 adjacent the pulley 42.
Centrally mounted on the shaft 52 is a lower circular cutter blade 58 while a like upper circular cutter blade 59 is mounted on the shaft 51 in such manner that the peripheral edge portions of the blades 58 and 59 are in abutting relationship.
A stripper plate 60 is carried by a transverse shaft 61 mounted in the frame and the free edge of the plate 60 lies adjacent the feed roller 32.
In operation, it will be apparent that a stack of magazines 62 to be destroyed is first placed upon the shelf 28 after the lower edge of the wall 25 has been adjusted vertically with respect to the feed roller 32 by means of the handle 23 whereby one magazine at a time may pass between the wall 25 and roller 32 according to the thicknesses of the particular magazines being treated in the machine.
The stack of magazines is then pushed rearwardly from the shelf 28 to the supporting rollers 30 which allow the stack to roll downwardly and rearwardly until it abuts the wall 25 whereupon the spikes 33 of the feed roller 32 will engage and pull rearwardly one magazine at a time from the bottom of the stack, moving the same to the belts 39 over the stripper plate 64 The belts 39 then successively carry the magazines 62 to the cutter blades 58 and 59 which act to sever them and deliver the same to the rearward end of the belts where they may be removed for further disposal.
While but one form of the invention has been shown and described herein, it will be readily apparent to those skilled in the art that many minor modifications may be made without departing from the spirit of the invention or the scope of the appended claim.
What is claimed is:
A machine of the character described, comprising a frame, a pair of upwardly extending sidewalls carried by said frame, a vertically extending hopper wall mounted substantially centrally between said sidewalls, a toothed feed roller transversely extending between said sidewalls immediately below said hopper wall, an upper and a lower relatively thin circular cutter blade, said blades centrally mounted between the rearward portion of said sidewalls, a pair of endless driven belts mounted horizontally adjacent to and at either side of said blades and adapted to carry magazines and the like to and beyond said blades, said blades being in overlapping cooperative engagement in substantially the same horizontal plane of that of the upper flights of said endless belts, and means for delivering the bottom one of a stack of magazines successively to said feed roller, said means comprising a series of transversely extending parallel supporting rollers carried by the forward portion of said sidewalls, and means for vertically adjusting said hopper wall with respect to said feed roller, said supporting rollers having their axes arranged in a rearwardly and downwardly extending plane which includes the axis of said feed roller, said feed roller being vertically spaced from the upper flights of said endless belts.
