Specification of Letters Patent. Patented Sept. 13, 1910. Application filed July 18, 1907. Serial No. 384,408.
To all whom it may concern:
Be it known that CHARLES D. GRIMES, de-
' ceased, late a citizen of the United States% 1 adapted for formin and resident of Dayton, in the county 0 Montgomery and State of Ohio, did invent certain new and useful Im rovements in Machines for Forming and ttaching Fasteners to Paper Receptacles, of which the following is a specification.-
The invention relates to punch presses and particularly to such machines especially and securing metallic fasteners to paper oxes and similar purposes.
The object of the invention is tosimplify the structure as well as the means and mode of operation of such devices whereby they sides of the box or bucket and clench the same as is hereinafter described.
With the above primary and other incidental objects in view, as will appear from the specification, the invention consists of the means, mechanism, construction and mode of operation or their equivalents hereinafter described and set forth in the claims.
In the drawings, Figure 1 is a side elevation of the assembled machine. Fig. 2 is a front elevation from the right in Fig. 1. Fig. 3 is a detail sectional View of the reciprocating head showin the various punches and plungers, an the clenching mechanism. Fig. 4 is a plan view of the table of the machine. Figs. 5-6--7 and 8 are detail views of a punch, the die, the stripper, and one of the clincher slides respectively. Figs. 9 and 10 are perspective views of the material straightener and feed device respectively. Figs. 11 and 12 are detail views of the non-repeating clutch. Fig. 13 is a perspective view of one form of fastener formed by the machine, but the machine is not limited to this particular form of device. Fig. 14 shows a portion of a folded paper box with the fastener attached.
Like parts are indicated by similar charactors of reference throughout the several views.
Referring to the drawings, 1 is the main frame formed bifurcated and provided with bearings in the upper portion as best shown in Fig. 2 for the main shaft 2. Mounted in suitable brackets on the main frame is a counter shaft 3 which forms the fulcrum for certain levers hereinafter mentioned. The main frame is provided with a table 4 at one side thereof, over which the material is passed and on which the forming and securing operations are performed. Formed in-the main frame above the table 4 are suitable ways, in which is mounted a reciprocating head 5 carrying various punches and plungers. The ways of the reciprocating head 5 comprise one stationary gib 6 forme integral with the frame and an adjustable gib 7, which may be adjusted to take up wear by a series of adjusting screws 8, an is secured in place by lock nuts 9. The stud holes in the gib 7 are oblong as at 10 to permit the said adjustment.
The main shaft 1 is formed at one end into a crank or wrist pin to which the reciprocating head 5 is connected by a pitman 11. The head 5 is thus given a vertical movement by the rotation of the shaft 1. Also secured on the crank of the main shaft 1 is head 12 having therein an undercut slot 13 within which is engaged the head of a bolt 14 forming the pivotal connection of a link 15 attached at 1ts opposite end to the feed lever 16 which is pivoted at the counter shaft 3. The bolt 14 is adjustable within the slot 13, thereby providing for adjustment of the stroke of the feed lever 16. At its lower end the feed lever engages and actuates a feed device for the strip of tin or other material which is passed to the machine from a suitable supply reel. The material in entering the machine first passes through a straightening device, best shown in Figs. 1 and9. The straightener consists of a stationary block 17 secured to the rear end of the table 4 having secured thereto an adjustable gage plate 18 having a recess in the upper end throu h which the material passes. A spring pressed presser block surmounts the block 17 and is forced downward on the material by springs 19 located about studs 20 on which the presser block is adapted to slide. The gage plate 18 is preferably adjusted slightly above the block 17 as indicated in Fig. 1. By this device all kinks and bends or indentations are removed from the strip. The material next passes to the feeding devlce shown in Figs. 1 and 10 which consists.
movement of the lower end of the feed lever,"
due to the eccentric connec ion of the link 15 with the main shaft 1, caiises the gripper jaw 24 to move on its pivotal connection with the lugs 23 and the strip of material which passes below the jaw and between the lugs 23 will be impinged between the forward lower edge of the jaw 24 and the upper surface of the member 21. Additional movement of the feed lever causes a corresponding forward movement of the feed slide 21, drawing the metal strips from the reel, and advancing the forward end over the die 26 located in the forward part of the table 4.
Upon the returnv movement of the feed lever and slide the strip will be released by the jaw 24 and the slide 21 will return independent of the material. To prevent the engagement of the jaw 24 with the material on the return stroke, the jaw is provided with downward projecting lugs 25 adjacent to its rear edge which limit the rearward movement of the jaw by engaging the slide on opposite sides of the strip.
By the action of the feeding device the forward end of the strip of material is advanced over the die block 26 located in the table 4. The punches corresponding to, the die block 26 are two in number, and are carried by the reciprocating head 5. They are the cutting off punch 27 and the perforating punch 28, by which the securing tines are formed. Each of the punches are provided with shanks 29 which extend into' suitable openings in the head 5 and are adjusted by adjusting screws 30 bearing on the ends of the shanks, and are secured by set screws 31.
The perforating punch is preferably formed with a removable bit 32 (see Fig. 5) to facilitate sharpening and renewal of the punch. This punch is bifrucated having triangular legs, the lower ends being inclined inward. The perforations formed be ing in shape of two isosceles triangles arranged base 'to base as shown by the ori-- fices 32* in the die block 26 with which the punch coiiperates. The two outer faces of the respective legs ofthe punch form the cutting edges while the inner or adjacent sides have a bending effect on the triangular flaps bending theni perpendicular to the plane of the ,strip to form the tine'sas at 33, Fig. 13.
The cutting off punch 27 is preferably double convex in cross section as shown by the orifice 34 in the die block 26. By this form both ends of the finished fastener are rounded as shown; however, any other shape punch may be used giving to the fastener one round and one square end, or two square ends or those of the other shapes as'may be desired.
The punches operate simultaneously to cut off the end of the'strip which has been previously perforated, and to perforate the end of the strip for the next fastener.
Spring pressed upward on four studs .35 by springs 36 and extending over the die 26 is a stripperplate 37 having openings 38 39 therein through which the respective under side for the strip of material. A second plate 40 is similarly mounted below the plate 37 and extends under the strip of stock material to raise it with the stripper. The plate 40 is cut away to permit the passage of the tines 33 after being formed and so as not to interfere with the die block 26. The construction of the stripper is best shown in Fig. 7. Y
Mounted in the head 5 on either side of the punches 2728 are spring pressed vertically movable plungers 41 having reduced shanks 42 which extend through chambers within the head 5 and are provided with springs 43. Upon the initial downward movement of the head 5 the plungers 41 engage the stripper plate 37 and force it down against thecompression of its elevating springs. Upon further movement of the head the plungers 41 are depressed within the head and the punches 2728 pass through the openings in the stripper plate and coeperate with the die block 26 to sever the finished fastener and form the tines on the next succeeding device. On the upward movement of the parts the punches will be withdrawn from the work and the upward movement of the stripper will be limited by the heads of the studs 35.
Secured to the forward end of the table 4 is a cone 44, shaped to fit the box or bucket to which the fastener is to be attached. The machine is preferably equipped with a series of such interchangeable cones of different s1zes.
Located forward of the die block 26 in the table 4 is the clenching mechanism comprising two sliding clencher blocks 45 normally spring pressed apart by an intermediate spring 46. The clencher blocks 45 are formed as in Fig. 8 to fit a rabbeted slot in the table 4 within which they slide. They are retained within the slot by a plate 47 secured to the under side of the table which 85 punches pass and a shallow groove in the Fig. 3 formin respective blo s 45 as indicated. T e mem-' further forms a gliide for the bifurcated member 48 by whic the blocks 45 are caused to approach each other. The upper ends of the member 48 are inclined as best shown in cam faces which en age the ber 48 is actuated by a rock arm 49 on a counter shaft 50 in the base of the machine. There is also on said counter shaft 50 a rearward extending rock lever 51 connected by a link 52 with a lever 53pivoted on the counter shaft 3. The lever 53 at its forward end engages a suitable cam 54 on the mainshaft 1.
Thus upon rotation of the main shaft 1, the
cam-54 will operate the lever 53 to rock the counter shaft 50 through the link 52 and rock arm 51. The rock arm 49 being se-.
cured on the shaft 50 will be elevated and so move the member 48 upward through the plate 47; the inclined inner faces of the member engaging and forcing together the clencher blocks 45.
In practice the rece tacle is placed on the cone 44 with the portion to which the fastener is to ,be attached over the clencher blocks 45.
Upon operation of the machine the end of the stock material having the tines formed thereon as before described is advanced until the tines 33 are over the space intermediate the blocks 45. Located in the head 5 immediately over the clencher mechanism is a vertically movable spring pressed plunger 55 which as the head 5 moves downward in-per formance of the operations before described, bears on the fastener about to be cut from the strip and forces the tines 33 through the side of the receptacle and into the space between the blocks 45. The member 48 then acts to operate the blocks 45 thereby bending the tines 33 to parallelism as indicated in Fi 14 and by dotted lines, Fig. 13 which comp etes the operation. The fastener is adapted to the thrust through a suit-able opening 56 in the opposite lid of the reoep tacle and bent to secure the parts in closed position.
Inasmuch as the complete cycle of operations is performed during each revolution of the main shaft, a non-repeating clutch is provided. The drive pulley 57 is loose upon the main shaft. Securedto the main shaft adjacent thereto is a clutch body 58 having an annular groove 59. A s ring pressed plunger or bolt 60 is located within the body 58 and intersecting the groove 59. The plunger 60 is provided with an inclined notch 61 with. which engages, as the body rotates the inclined head 62 of a vertically movable spring pressed plunger 65 which extends Within the groove 59. The plunger 60 normally extends beyond the body 58 and engages an inclined depression 63 in the hub of the pulley 57. As the body in rotating reaches the inclined head 62 the advance drawn by the inclined hea edge of said head engages the notch 61 in the bolt and withdraws the bolt from engagement with the pulley} against the tension of the sprin 64. he lower end of the spring presse plunger 63 is connected to a foot treadle of ordinary type, not shown in the drawing. U on operation of said treadle the head 62 is withdrawn from enagement'with the bolt 60 and permitsthe oltto spring outward into engagement with the pulle 57 until the end of the next revolution, w en it is again en aged and with- It will be'seen that there is thus provided a machine possessing the particular features of advantage before enumerated as desirable, and which obviously is susceptible of modification in its form, proportion, detail construction and arrangement of parts without departing from the rinciple involved or sacrificing any of its a vantages.
