Specification of Letters Patent.
Application filed December 14, 1906. Serial N0- 347,834.
Patented Aug. 27, 1907.
suitably small, and more or less nearly similarly shaped and uniformly sized pieces.
An object of the invention is to devise a machine for the purpose indicated which has the capability of a large amount of stock reduction in a given time.
Another object is to so construct the machine that it may have a long life, notwithstanding the wear to which the parts, especially the shears comprised therein, are subjected. Another object of the invention is to so construct the machine that the shear comprising parts therein become self sharpening. And another object of the invention is to so construct the machine that it is of great durability.
The invention is described in conjunction with the accompanying drawings and the particular features thereof are covered in the claims.
In the accompanying drawings,Figure 1 is a plan unusual simplicity, of cheapness of manufacture, and
view of the machine; Fig. 2 is a sectional elevation as taken on line 2-2, Fig. 1; Fig. 3 is a perspective view, with parts broken away, of the portion of the machine which is herein termed the fixed bed plate. Fig.
4 is a perspective representation of some of the individual teeth and spacing-blocks comprised in the bed plate; Fig. 5 is a perspective view illustrating abed plate of modified form.
Similar characters of reference indicate corresponding parts in all of the views.
In the drawings,-A represents the frame of the machine comprising opposite upright sides 10, 10, having L- shaped lugs 12, 12, on the inner faces thereof, each provided with an aperture 13.
13 represents a rotatable body or cylinder journaled in said frame and having essentially one, and in practice preferably a plurality of helically extending series of outwardly projecting separated tapered teeth 14, 14. The shaft orarbor of the rotatable body B has a large spur gear wheel 15 thereon, meshing into which is a considerably smaller spur gear wheel 16 affixed on the driving shaft 17 to which the driving pulley 78 is provided whereby the rotation of the shaft through means of a belt may be accomplished for the driving of the rotatable tooth carrying body' at appropriate speed and with great power. g v
G represents the portion of the machine, which, as an. entirety, is herein termed the bed plate, the
same having a series of separated teeth evenly spaced I and arranged in a horizontal line parallel with the a'xis of the cylinder 13 and positioned so that the teeth revolubly carried by the cylinder willsucccssively pass with shearing actions in close contact with the surfaces of, and through the. spaces between, the teeth of the bed plate, which latter teeth are tapered so that both sets of teeth and the walls of the intermediate spaces between the individual teeth are complemental to each other.
Describing the bed plate exactly as constructed and mounted in the preferred form, it will be perceived i that the same comprises an L-shaped bar a having appurtenant thereto and located above the ledge portion 18 thereof, a section 19 in the form of a rigid metallic strap, arranged vertically adjustable relatively to the part 18 by the screws 20 which have thread engagements vertically through such portion 18 with upper end supporting bearings against the underside of the section 19. The L-shapcd bar is supported at its end portions on the aforementioned opposite L-shaped lugs 12 of the frame sides. The series of teeth b of the bed plate are constituted by tooth sections in the form of comparatively vertically long, or high, steel blocks, the bases of which rest on the vertically adjustable section 19. The upper ends of the said tooth sections or blocks extend considerably above the upper edge of the L-shaped bar a, all terminating at a normal level more or less nearly corresponding to that of the axis line of the cylinder B. The blocks are at their upper end portions forwardly tapered, as indicated at 22, conformable to the tapering or beveling of the teeth projecting outwardly from the cylinder.
23 represents spacing blocks between the tooth sections, the same being of the same height as such tooth sections, but of considerably less width so as to leave the proper tooth spacing and to constitute, by their upper forward portions, shear edges 24, against which the points of the cylinder teeth coact, while the sides of the cylinder teeth coact with the lateral edges or upper corners of the said tooth sections, The upper bed plate surface, constituted by the upper ends of the closely united tooth sections and spacing blocks, is one that is horizontal and flush. The blocks 25, shorter than the tooth sections and spacing blocks, are provided between the lower portions of the tooth sections and are positioned facewise against the spacing blocks.
d represents a clamping plate of the same length as the L-shaped bar or body a of the bed plate. --This clamping plate is firmly secured on the forward edge of the horizontally disposed ledge member 18 of the aforesaid bar a, being secured by the screws 27, and tightly binds all of the tooth sections and spacing blocks, so that when united the tooth comprising" plate is to all intents and purposes the same as if integrally made. V
The bed plate bar a has end cheeks or right angular vertical lugs 28, 28, to constitute stops against which may be positioned thetooth sections and intermediate blocks, and also against which engage the inner ends of screws 30 which have thread engagements horizontally through the frame sides in a line of the length of the bar a. These screws 30 are available for positioning and holding the tooth comprising bed plate positioned with exactness, so that the centers of the spaces between the bed plate teeth will be coincident with the centers of the teeth of the cylinder.
32, 32, represent adjusting screws passing through the lugs 12 at the inner portions of the frame sides in lines at right angles to the length of the bed plate bar a and with bearings against the back thereof; and 33, 33, represent a pair of screws extending horizontally loosely through the apertures 13 therefor in the aforesaid opposite side lugs 12, and with screw thread engagements into the opposite end portions of the bar a. By loosening the screws 33 and turning up the screws 32 the bed plate may be bodily set forwardly in slight extents, towards the axis of the cylinder, as may be required from time to time in consequence of the wearing away of the shearing parts, more especially the teeth of the cylinder. And after the bed plate shall have been slightly forwardly moved, the" confining screws 33 are again tightened so that their heads hind against the rear side of the lugs 12 outside of the margins of the slot 13. The slots 13 are made slightly wider than the diameter of the shanks of the screws 33 so that there may be a slight play of the screws horizontally in an endwise adjustment of the bed plate, see Fig. 1.
ff represent a pair of feed rolls to the rear of the bed plate teeth with their nipping part adjacent peripheral portions at or slightly above the level of the tops of the bed plate teeth; and g represents a chute or guide for the rags or. other stock to be brought to reducing action by the machine. The said feed rolls are geared together at one end of each, 37 representing the intermeshing spur gears therefor; and the lower feed roll has on the opposite end from that on which is secured one of the gears 37 a larger spur gear wheel 38 which meshes with a spur gear wheel 39 which is fast on the arbor, or integrally formed journal, of the cylinder B,- this last mentioned gearing constituting the driving means for the feed rolls.
The stock fed to and through the feed rolls and advanced forwardly therebeyond over the teeth of the bed plate is cut into four sided small pieces, the shapes thereof corresponding to those of the eomplemental.
teeth of the bed plate cylinder; and because of the helical arrangement of each of the endwise arranged rows or series of the cylinder teeth, a cylinder tooth at one end reaches the shearing plane and performs its individual cutting action slightly before the next revolving cylinder tooth of the same series, so that there is a distribution, as to time, within the period of passage of a helical series of cylinder teeth past the bed plate teeth, of the shearings performed by and between individual pairs of the teeth.
The teeth of one of thetooth comprising bodies in this machine, preferably those of the cylinder, are composed of a softer metal than are the teeth of the relatively opposed body, and in practice the bed plate teeth are composed of steel, hardened; and the cylinder with its outwardly extending teeth arranged in gradually sweeping helical lines is made of cast iron. Consequently the cylinder teeth are self sharpening in their shearing passages through'and in relation to the harder bed plate teeth. From time to time as the cylinder teeth are perceived to have been worn away, the bed plate isvery' slightly forwardly adjusted, the provisions for which have been hcreinabove pointed out,so that the complemental sets of teeth will bottom and be in shearing contact at all of the tooth sides and intermediate walls.
The cylinder teeth are constructed with reinforcing rearribs or webs 45 whereby liability of .tooth breakage is lessened.
The bed plate maybe bodily taken out from the maworn and dull at the corners or shear edges of'and between the bed plateteeth; and to compensate for any reduction in the height of the teeth, the tooth series may be bodily slightly elevated by the adjusting screws 20 operable to slightly raise the movable bed plate section 19 on which the series of individual tooth sections and their spacing blocks rest.
As hereinabove intimated, the bed plate is to all intents and purposes an' entirety, or the same as if integrally made, so far as its function is concerned, for a given period of effective operativeness; but by making it sectional as regards the individual tooth sections, the latter are susceptible of being made of very simple and easily produced forms from good steel and satisfactorily hardened, and wear compensation provided for.
In Fig. 5 a bed plate is represented in which the tooth sections b are horizontally arranged and clamped within an L-shaped bar a the longer diameter of which latter is also horiz0ntal,the object of this illustration being to indicate that the precise formation and arrangement of a bed plate such as represented in the preceding viewsneed not necessarily be strictly followed, although such is the preferred one for reasons of practicability and expediency.
It will be seen that, in both the form of bed plate illustrated in Fig. 5 and that shown in the remaining views, the fixed tooth members are mounted in what is, in effect, a casing, composed of the L-shaped bar with its end members, and the clamping plate. In both forms, also, means is provided for adjusting the tooth members, and the spacing members, in and out of the open side of the casing.
A machine made in accordance with this invention is especially available for the reduction of rags for paper stock; and such machine has also been extensively utilized in the manufacture of confetti from tissue paper.
