CRIMPING MACHINE.

Application filed April 7, 1923. Serial No. ($30,434.

To all whom it may concern:

Be it known that I, Gnonon H. E. BER- THOLD, a citizen of the United States, and resident of East Orange, in the county of Essex and State of New Jersey, have, invented certain new and useful Improvements in Crimping Machines, of. which the following is a specification.

The object of my invention is to provide a simple and efficient machine or fixture adapted to crimp or dent metal sleeves, ferrules or the like, and is particularly adapted to at.- tach terminal sleeves or ferrules to insulation upon insulated electrical conductors by squeezing the sleeves or ferrules to crimp or dent the same into the insulation.

My invention also comprises novel details of improvement that willbe more fully hereinafter set forth and then pointed out in the claims.

Reference is to be had to the accompanying drawings forminga part hereof, wherem Fig. 1 is a plan view of a machine, embo'dymg my invention;

Fig. 2 is a section on line 2, 2, in Fig. 1;

Fig. 3 is a detail section, enlarged, show- .ing parts in crimping position;

Fig. 4 is a side view;

Fig. 5 is a plan view illustrating the crimp-.

ingjaws, the rotative cap being-omitted;

1g. 6 is a detail plan View partly in section, and

-Fig. 7 is a detail side view of the guide block for the crimping jaws.

Similar numerals of reference indicate tent I provide a stop wllar 17 that encircles the guide block 2 beneath the ring 9, which corresponding parts in the several views.

At 1 is a suitable .base shown provided with le s l which may be attached to a suport, w ich base'isprovidedwith a ide Blocker projection 2.. Said parts ma e secured together by screws 3. The :gui e block or, projection 2 is shown provided with a cen tral bore 4 to admit an article 5, such as an electric terminal, (Fig. 3) the'upper surface of which block or pro ection is provided with radial rooves 6 communicating with bore 4. Radiallydisposed crimping aws are slidable in the grooves 6 to engage the terminal 5, the inner-ends of, which jaws are shown tapering. at 7, (Figs. 1 and 5), and

preferably downwardly inclined at 7" to ormcrimpingedges or jaws. At 8 is a rotative cap or head journaled upon guide block 2 and shown provided .with a recess receivfrom the jaws 7, whereby I ingthe upper portion of said block, a flange 8 of said cap or head encircling the guide block 2, whereby said ca or head is rotatively guided. At 9 is a gi ring encircling the guide block or projection 2 and located under an annular or projection 2 ofsaid block. Said'ring and thecap 8 are detachablysecured together by means of screws 10 and therebythe cap 8 is rotatively retained upon block 2. The cap 8 is pro-' vided with an opening 8 registering with the bore 4 for admissionof the .terminal 5 and the insulated electric-conductor 5". The cap 8 is provided with means to move the jaws 7 radially toward and from the axis of the guide block as said cap is rotated back and forth, for which purpose the inner face of'said cap is provided withcam grooves or slots 11 that receive projections 12 extending when the cap is rotated back and forth said jaws will be reciprocated toward and from the terminal 5 located within bore4. The projections 12 are shown comprising pins provided with rollers 13 operative in the cam slots 11' to reduce friction. While the cam slots 11 may bemilleddirectly in the inner surface of the top of cap 8, I preferably form said slots in a hardened apertured steel plate 14 that is secured to cap 8 by means of'screws 15'. The

cap 8 is shown provided with a shank'8 to.

which a lever 16 is secured for rotating to crimp or dent the terminal 5 into the in: sulation of conductor 5 to the desired exca i B. I 0 limit the inward movement of aws 7 collar is slit at 17 a and rovided with a screw r .18 adapted to clanip t e collar in setposi- 0 tion around guide ck 2. The collar 17 is .provided with a projection 17 below the ring 9 and in the path of a projection 9 dependiii from said ring, (Figs. 2 and 4) The co lar 17 may be set in such position around guide 2 that its stop 17 will be engaged by the stop .9 of rin 9 when the cap 8 has been rotated to the esired extent in the direction 'of the arrow min Fig. 1 to i nal 5 to cause the rear portion of the latter to be presented in crimping position with relation to the crimping jaws 7, (Fig. 3). The stop 19 may be adjusted longitudinally according to the dimensions of terminals to be crimped on the insulation of different conductors.

When it is desired to attach terminals to insulated electric conductors said terminals are placed upon the insulation, the jaws 7 are expanded by rotating cap 8 in the direction reverse to the arrow a in Fig. 1, the terminal is inserted through opening 8' into bore 4 to rest against stop 19, and cap .8 is rotated in the direction of said arrow until the stop 9 engages stop 17, whereby the jaws 7 will be advanced toward the terminal to dent or crimp the same, (Fig. 5). The cap is rotated reversely to spread the jaws to release the crimped terminal. By means of the construction set forth the marginal portion of the tubular terminal may be crimped or dented uniformly into the insulation of the conductor to retain the terminal thereon ,withoutdanger that the terminal will be crimped too much or irregularly into the insulation, since the jaws 7 may all be given an equal movement toward the terminal, and the extent or depth of such crimping may be regulated as required. 7

Having now described my invention what I claim is LA crimping machine comprising a plurality of spaced jaws, guiding means for said jaws, a rotative cap having means cooperative with said jaws to move said jaws toward and from the axis of the cap when it rotates, and means adjustable in the direction of rotationoof the cap and cooperative with the latter to limit rotation of the cap in a direction to advance the jaws.

vblock to limit rotation of said cap in the direction to advance the jaws axially respecting the cap.

3. A crimping machine comprising a guide block having guiding means for aws, a plurality of jaws operative in said guiding neaii's, a cap rotative upon said guide block, means cooperative between the cap and jaws for reciprocating the latter as the cap is rotated, said guide block having a projection, a ring connected with said cap to rotatively retain the cap upon the guide block, a stopcollar having a projection. means to secure said collar in set position around the guide block, and a projection upon said ring to cooperate with the first named projection to limit rotation of the cap.

4. A crimping machine comprising a plurality of spaced jaws, guiding means for said jaws provided with a bore to receive an article to be crimped, a cap rotative upon the guiding means, means cooperative between the jaws and the cap for reciproeating the jaws during rotations of the cap, said cap having an opening registering with said bore, a stop within said bore to engage said article to regulate its position between said jaws, said stop being axially adjustable in said bore, and means to retain said stop in adjusted position.
