To all whom it may concern Be it known that I, EDWARD W. Arrnnnnce, citizen of the United States, residing at Algoma, in the county of Kewaunee andState ofWisconsin, have invented cer-' tain new-and useful Improvements in Machines for Applying Metal Tips to Cord,

of which the following. is a specification,

reference being hadto the accompanying drawings.

This invention relates to, a machine for -applying metal tips to the ends of cord "lengths such as are employed in the manuthe provision of means whereby thebends' are formed in the metal bands in' the forward' cutting stroke ofthe knife.

Still another object of the invention is to provide a m achine for the above purpose -whereby thetipping of cords composed of a plurality of twisted strands is greatly facilitated thus admitting of a large number of the'cord being provided with the tips -in a minimum length of time and with a minimum of labor upon the part-of the operator. c

With the above and other objectsin view as will become apparent as the description proceeds, the invention consists in certain constructions, combinations and arrangementskif the parts that I shall hereinafter fully describe and claim.

For a full understandingof the invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a side elevation of a cord tipping machine embodying the present invention; Fig. 2 is an enlarged vertical section of one end of the machine; Fig. 3 is a transverse section taken on the line 33 of Fig. 2; Fig. 4 is a view similar to Fig. 2; showing the cutting knife at the end of its forward stroke; Fig. 5 is an inverted perspective view of the knife; Fig. 6 is a perspective view of the removable die block; F 1g. 7 1s a detail view of the operating means; Fig.8 is a section taken on the line 88 of F ig. 7. Fig. 9 is a detail section taken on the line 99 of Fig. 2.

Referring in detail to the drawings, 5

designates two parallel longitudinal base bars which are provided with suitable attaching. ears' 6 whereby the same may bebolted or otherwise secured to a bench or other suitable support. These side bars are preferably formed of cast iron and are reduced in height at one of their ends as indicated at 7. The bars 5 are secured to'the opposite longitudinal edges of a steel base bar 8 which is arranged bet-ween said bars,

by means of a plurality of screws 9. The upper surface of this steel bar. 8 is disposed below the plane of the upper edges of the reduced end portion 7 of the bars5. The base bar 8 between the upwardly extending walls 10 of the side bars 5 is of increased thickness and is provided with a longitudinal groove 11.

Between the side walls 10 of the bars 5, a rod 12 is slidably mounted. To this rod, the knife 13 is attached in any preferred manner and rests upon the upper surface of the base bar 8. This knife at its forward end is provided with a. transversely extending cutting-edge indicated at 14. Upon the under surface of the knife 13, a vertically disposed longitudinally extending blade 15 is formed, having vertical cutting edge 16 at its forward end. This latter knife blade moves in the longitudinal groove or channel 11 in the upper surface of the bar 8.

. Beyond one end of the groove 11 and in spaced relation thereto, a longitudinal arm or extension 17 is arranged between the re-v duced ends 7 of the side bars 5, and closely fit therein for adjustment toward and from the end of the groove or channel 11. Between the end of this extension 17 and-the groove 11, a hardened steel die block 18 is adapted to be arranged between the side bars 5. This block is provided in its upper grooves surface with a longitudinal groove 19 which forms a continuation of the groove 11 and receives the additional knife blade 15 on the under side of the knife 13. A transverse groove is also provided in the upper surface of the block 18 and intersects the longitudinal groove 19 intermediate of its ends. The purpose of this latter groove will be more fully disclosed in the following description. The ar'rn or extension 17 and the block 18 are removably held in place by means of suitable set screws 18.

At the ends of the vertical walls 1O of the bars 5, and. upon the reduced end portions of said bars, the upright or vertical bar 21 is secured and is provided in its lower end with a central opening 22 for the passage of the knife 13*. Upon one face of this vertical bar, a guide ,plate 2-3 is secured. Between this guide plate and the bar 21, a thin sheet or plate of steel 24 is secured. This steel sheet is interposed between a longitudinal guide channel 25 formed in the inner face of the plate 23 and the guide 26 formed in the opposed face of the vertical bar 21 through which the sheet metal bands 27 move. Thesebands are drawn from independently movable H drums 28 mounted upon a suitable support 29 fixed upon the upper end of the vertical bar 21. In the guide channel 25 of the plate 23, the vertically movable die 30 is mounted.

A frame is mounted upon the base of the machine, said frame including longitudinal bars 31 which may be integrally formed upon the upper ends of the standards 32 secured at their lower ends to the base of the machine. The forward ends of the longitudinal bars 31 of this frame are connected to the vertical bar 21 and upon the bars 31,

the supports 29 for the band reels are arranged. Between the ..longitudinal frame bars 31 a'bell crank lever 33 is fulcrumed as indicated at 3 1. One arm of this lever extends forwardly and is disposed through an opening provided in the upper end of the movable die 30. The other arm of this lever extends downwardly and is connected by means of a longitudinal bar 35 with the depending arm of a bell crank lever 36 which is fulcrumed as indicated at 37 between the rear ends of the longitudinal frame bars 31. To theother arm of this bell crank lever the ing rod 38' is attached. The lower end of this rodis connected to the crank 40 of a shaft 39 journaled in suitable bearings 41 mounted upon the upper edges of the longitudinal bars 50, of a suitable supporting frame. Upon this shaft, a band or belt wheel 51 is loosely mounted and a collar 52 is keyed upon said shaft for sliding movement. This collar is provided with an arm 53 for engagement with one of apair of upper end of a connectpins indicated at 5 1 which project from one face of the belt wheel 51. p A yoke 55 is fulcrumed as indicated at 56 upon one of the frame bars 50, the arms of saidyoke being disposed upon opposite sides of the collar 52 and in an annular groove formed therein. The lower end of this yokeohas an angular extension 57 formed thereon, to the end of which the treadle bar 58 is fulcrumed as in dicated at 59. The forward end of this treadle bar moves in a suitable guide bracket 60. The rear end of this treadle bar is pivoted as shown at 61 upon the supporting frame. This treadle bar ,at its front end is yieldingly held against downward movement by means of a coil spring 62.

To the lower end of the connecting rod or bar 38, one end of a coil spring 63 is attached, the other end of said spring being suitably securedto thesupporting frame.

A longitudinally extending leaf spring 64: is also mounted in the frame and bears at its free end against the lower end of said connecting red when the same is in its normal position. This spring intermediate of its ends rests upon a lug or other suitable support 65 securedto the frame. The depending arm of the bell crank lever 36 is loosely disposed in an opening provided in the rear end of the knife, carrying bar 12, so that said bar and the movable die 30 will be simultaneously actuated, upon the movement of said lever.

Having now described the construction of the machine, its operation will be understood as follows: The operator takes his position in front of the machine and arranges upon the extension bar 17 a number of skeins of ro e or twine to be tipped. It

will be observed that the lower edge of the sheet of steel 24: which is arranged between the guide plate 23 and the vertical bar 21, is disposed closely adjacent to'the upper surface of the knife 13. The sheet metal bands 7 27 extend downwardly below the edge of this steel sheet. Before the twine is placed m position in the transverse groove of, the die block 18, the operatorv presses downwardly upon the forward end of the treadle bar 58, thereby shifting the collar 52 upon the shaft 39 so that the arm 53 thereof will be engaged by one of the ins 5 1 on the belt wheel 51, thus rotating the shaft 39 and through the medium of the crank shaft and the connecting rod 38, oscillating the bell crank-36. The operator removes his foot from the treadle bar when the same has been forced downwardly and the coil spring 63which has been placed un der tension completes the revolution of the stopped by theengagement of thelower endof the connecting rod "with the end of the shaft 39, the rotation of the,shaft being leaf spring 64. During the latter half of the revolution of the shaft, the knife bar is being retracted. In the forward movement of the depending arm of the bell crank lever 36, this knife bar is moved forwardly so that the knife 13 will engage the lower ends of the metal bands 27 and bend the same forwardly. In the reverse movemovement cuts the metal bands and bends the same around the twine and simultaneously bends the lower ends of the bands remaining on the spool forwardly beneath the edge of the plate24. After the loops have thus been clenched around the twine, the

vertical knife blade-moving in the longitudinal groove of the die block 18, cutsthc twine between the loops. The tipped ends of the cord or twine are then removed by the operator. and the above described operation repeated. It will thus be seen that the forwardly bent ends of the metal bands on the spools are simultaneously fed into the transverse groove of the die block and bent to'produce the hooks thereon by the downorder to prevent the same unravelin ward movement of the die 30. The leaf spring 64 acts as'a stop for the shaft 39 so that the'same will make but one revolution upon each downward pressure of the operators footupon the treadle bar and the release-of said bar.

. From the foregoing, it is believed that the construction, operation and many advantages of the machine will be clearly understood. It will be obvious that by means of the same, the tipping of rope or twine such as is used. in the construction of fly nets, in will be greatly expedited.

It will be obvious that if desired, the foot treadle for'the manual control of the machine may be eliminated and the machine operated from any suitable'source of power. The stationary'die block18 may be readily removed from the bed of the machine andv another substituted therefor when cord or twine of various thicknesses is to be supplied with the metal tips. This is also true of the movable die member which forms the loops or hooks upon the ends of the metal bands, as well as the double knife and-the metal plate 24. It will further be understood that while I have shown and described the pre ferred construction and arrangement of the several parts, the invention is nevertheless,

susceptible of considerable modification in the form, proportion and arrangement thereof without departing from the essential features or sacrificing any of the advantages thereof.

Having thus described the invention, what is claimed is:
