CIGAR-BOX-TRIMMING MACH l N E.

SPECIFICATION forming part Of Letters Patent No. 460,877, dated October 6, 1891.

Application filed September 19, 1890. Serial No. 365,478. (No model.)

To all 1071/0171, it may concern:

Be it known that l, HENRY LEIMAN, of New York city, in the county and State of New York, have invented a new and Improved Gigar-llox l rimming Machine, of which the following is a full, clear, and exact description.

My invention relates to an improvement in cigar-boX-trimming machines, and has for its object to economize in the construction of such machines and to so simplify the mechanism and render it automatic to such an extent that the services of two unskilled labor ers only will be required in the operation of trimming to feed the boxes to the machine.

The invention consists in the novel construction andco mbination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

7 Reference is to be had to the accompanying drawings, forming a part of this specification, in Which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is afront elevation of the machine partially in section, the section being taken through and beneath the table, as indicated by the line 1 1 in Fig. 3. Fig. 2 is a plan view of the machine. Fig. 3 is an end elevation. Fig. t is a longitudinal section through a portion of one of the saw-shafts and the pulley by means of which the shaft is rotated. Fig. 5 isafront elevation of a set of sawshafts, illustrating the position occupied by the saws carried thereby with relation to the box to be trimmed; and Fig. 6 -is a plan view of one of the lower saw-shafts and its connected adj usting-bars.

The frame of the machine consists of two end pieces 10, properly braced and having a vertical extension 11 at one side, upon which the bed 12 of the machine is laid and secured, the table 13 being also supported by the end pieces through the medium of suitable brackets, as shown in Fig. 3,theinnersidc of which table is spaced some distance from the bed. l'pon the bed 12 three upright carrier-blocks are supported, comprising an intermediate carrier lat. and two

end carriers

15 and 16. The carrier-blocks are capable of sliding laterally upon the bed, being provided with dovetailed slots in their bases, receiving a similar rib integral with the bed, as is best shown in Fig. 3. The center carrier is normally held in one position by a set-screw or its equivalent 5 but the side carriers are laterallyadj ustable through the medium of horizontal screws 17, connected therewith and held to turn in suitable bearings 17*, projected upward from the bed. being preferably manipulated through the medium of crank-arms applied to their outer ends. Upon the front upright face of each carrier-block a bracket is held to slide vertically, which brackets are designated, respectively, as 18, 19, and 20, and said brackets are raised or lowered by screw-shafts 21, one of which shafts is journaled in each carrier-block, the lower ends of the shafts be ing passed through lugs secured to the rear of the brackets, having threaded apertures therein, and the upper ends of the shaftare provided with bevel-gears 22, meshing with similar gears 23, fast upon a line-shaft 2i, journaled upon the upper ends of the carrier-blocks. The shaft 24 is preferably re volved through the medium of a crank-arm 25, as shown in Figs. 1 and 2. Beneath the sliding brackets 18 and 20 of one end

similar brackets

26 and 27 are rigidly secured to the

blocks

14 and 16, the lower bracket being omitted from the other end carrierblock. All of the brackets are provided with essentially triangular arms 27, projecting in the direction of the table, and in suitable bearings 28 at or near the apex of each bracketarm a horizontal saw-shaft 29 is journaled, the ends whereof extend beyond the arms, and in the base of the arm of each bracket two parallel adj usting-

bars

30 and 31 are held to slide. When two brackets are attached to a carrier-block, the base of the upper bracketarms faces the base of the lower bracket arms, as is best shown in Fig. 5, and when one bracket only is employed the base of the arms thereof faces downward.

The saw-shaft and adjusting-rods of the brackets attached to the outer carrier-block 16 are connected attheir outer ends by a yoke 32, preferably of triangular form, and the inner ends of each set of adjusting-rods are united by a horizontal guide'bar 38, essentially L-shaped in cross-section, the saws being mounted upon the inner ends of the shafts 29.

The attachments to the inner ends of the adjusting-rods and saw-shafts of the carrierblock 16 are duplicated upon the contiguous ends of the adj usting-rods and saw-shafts of the brackets located upon the intermediate carrier-block 14, the other ends of the said parts being united by a yoke in like manner with the outer ends of the corresponding parts upon the end carrier-block 16, as is best shown in Figs. 1 and 2. V

The yoke 32 of each bracket is connected with the opposed bracket-arm by a spring 34, the tendency of the said spring being to draw the yoke in the direction of the bracket-arm, as is best shown in Fig. 6. I

The saw-shaft connected with the end carrier-block has a saw attached at or near its inner extremity, the yoke connection with the'adjuting-rods being at the opposite extremity.

When two saw-shafts are connected with a carrier-block they are not parallel with each other-as, for instance, the inner end of the upper shaft 29 of the end carrierlG, to which the saw is attached, is given a downward inclination and the corresponding end of the lower shaftisgivenanupwardinclination. Thecorresponding ends of the shafts connected with the intermediate carrier are treated in like manner, the saw-carrying extremity of the shaft located upon the end carrier 15 being inclined downward. All of the saw-shafts are also out of parallelism with the front face of the carriers, the extremities to which the saws are attached all having a forward lateral inclination, except the shaft connected with the carrier 15, which is given a rearward inclination. The lateral inclination of the shafts is usually effected by transversely beveling the backs of the brackets in which the shafts are journaled, whereby one side edge is thicker than the other. The saws, which are designated as 35 in the drawings, are therefore inclined slightly both laterally and vertically, as is best shown in Figs. 5 and 6. The vertical inclination of the saw-shafts is usually accomplished by placing the brackets diagonally upon the carriers. The object of inclining the saws is to cause them to engage with the edges of the box to be cut when the edges are immediately over or under the saws and to prevent the saws from engaging with the trimmed sides or ends of the box and lacerating the latter as the box is carrie forward.

A hanger 37 is attached to the end carrier 15 below the plane of the bed 12, and in said hanger avertical saw-shaft 38 is journaled, provided with a drive-pulley 39, and to the upper end of the said shaft a saw 40 is horizontally secured. The saw is located above the bed, and its position is such that its inner peripheral cutting-surface is practically in vertical alignment with the vertical saw 35 above it. A second hanger 41 is secured to the front face of the bed parallel with the hanger 37, the hanger 41 being located. in front of the yoked extremities of the horizontal saw-shafts 29. In the hanger 41 a vertical saw-shaft 42 is journaled, also fitted with a drive-pulley 43 and having a saw 44 horiz'cntallyattached to its upper end, which saw is in horizontal alignment with the saw 40. The hanger 37 moves with the carrier to which it is secured, and the hanger 41 is capable of lateral movementupon the bed.

Between the opposed saw-carrying ends of the horizontal shafts journaled in the intermediate and end

carriers

14 and 16 two parallel tracks 45 are laid, which tracks are preferably angular or L-shaped in cross-section, the said tracks being located over the lower saws 35 of the said carriers, and at the point where the tracks cross the said saws recesses 46 are created in the tracks, as is best shown in Fig. 2, in order that the lower saws may engage with the edges of the boxes passed over the tracks. One of the tracks is rigidly attached to the bed and the other is laterally adjustable to and from the fixed track. The tracks 45 extend from the rear of the machine over the table 13. The adjustable track, however, is not attached to the table. Similar tracks 48 are laid between the horizontal saws 40 and 44, the inner face of the outer track being practically in vertical alignment with the outer face of the saw 35, connected with the carrier 15, as is best shown in Fig. 1. One of these tracks also is laterally adjustable, and each of the tracks is provided with a recess or slot in its'vertical member to permit the horizontal saws 40 and 44 to engage with the box passed over the tracks.

The brackets held to slide upon the

end carriers

15 and 16 have attached to their upper ends horizontal bars 49. The bars 49 are laterally adjustable, and to the inner end of each bar avertically-ad j ustable perpendicular arm 50 is secured, which arms are provided with shoes 51, integral with or attached to their lower ends. One of the arms 50 is 10- cated immediately over the space between the tracks upon which the boxes are to he slid in front of the vertical upper saws, the shoes 51 of the arm being adapted to bear against the upper surface of the box to be trimmed and prevent the said box from vertical movement when the saws are acting tached, preferably, to the center of the lower horizontal saw-shaft connected with the intermediate carrier 14, each of the horizontal saw-shafts being provided with a similar pulley. A wide pulley 60, secured to the driveshaft 52, is connected by a belt 61 with the pulley of the lower saw-shaft upon the end carrier 16. The drive-pulley 62 of the driveshaft 52 may be connected therewith at any suitable point. The pulleys of the upper horizontal saw-shafts are driven in any suitable or approved manner from counter-shafts preferably located overhead.

The attachment of the pulleys 59 to the saw-shafts 29 is somewhat peculiar and is illustrated in Fig. 4. The bearing 28, in which the shaft is held to revolve at or near the center of the shaft, is provided with an annular channel 63, extending through the bearing, whereby the latter is practically divided into two sections, and at the channeled portion of the bearing the shaft 29 is provided with a longitudinal key-slot G4. The pulley 59 has inserted in its periphery, preferably at the center, a key 65, the lower end whereof passes down through the channel 63 and into the key-slot 64:. It will thus be observed that the saw-sha t is capable of lateral movement and that while the shaft is being moved laterallyit is kept revolving by the key connection with its pulley 59.

In operation the box, with its bottom nailed on flush with one end only, is placed lengthwise-that is, with the sides facing, the front and rear of the machineupon the front or forward end of the tracks 48, top down, as illustrated in dotted lines, Fig. 1. The box is then fed rearward in any approved manner until the horizontally-aligning saws are reached,whereupon the bottom of the box is engaged by the shoe 51 of the presserarm 50, and in passing the saws the projecting cover edges and the unfinished bottom end of the box are neatly trimmed and rendered flush with the end boards. lVhen the box reaches the rear of the tracks 48, it is moved by an attendant stationed at the rear of the machine, turned, and placed upon the rear ends of the tracks 45 crosswise, as is also shown in dotted lines, Fig. 1, and in this position the box is fed to the vertically-aligning perpendicular saws. The Vertical saws as the box passes trim off any projection of the edges over the sides of the box at its top and bottom. Thus the box passes from the machine having all of its projecting edges made flush with its top, bottom, and sides.

In the event that a wide box is to be trimmed the sides or ends of the box, as the case may be, just. before reaching the saws engage with the guide-arms 33, connecting the adjusting bars 30, and force the said arms against the tension of the spring 34 to move a sufficient distance in the brackets to permit the passage of the box, and when the adjusting-rods are slid in their bearings by means of the yoke connection 32 of said arms with the sawshafts the said shafts are carried with them,

and the saws are thereby in every instance brought to the proper position to perform their work.

Having thus described my invention, I claim as new and desire to secure by Letters Patcut- 1.
