MAGNETIC CHUCK.

SPECIFICATION forming part of Letters Patent No. 766,201, dated August 2, 1904;. Application filed February 6, 1904.. Serial No. 192,292. (No model.)

T a/Z whom, it nfl/ay concern:

Be it known that I, CHARLES VW. SroNsEL,

a citizen of the United States of America, re-

siding at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Magnetic Chucks, of which the following is a specification.

This invention relates to magnetic chucks or carriers especially designed for use with machines for presenting articles for inspection of the kind set forth in my application filed September 25, 1903, Serial No. 174,577.

' Primarily the object of the invention is the provision of a magnetic chuck or carrier for presenting' the articles for inspection.

A further object of the invention is the provision of a magnetic chuck or carrier of peculiar construction and one in which the articles received at an angle from suitable conveyer mechanism may beadjusted to present them in proper position for the action of chucks or other devices by which they may be turned for inspection purposes.

2 5 A further object of the invention is the provision of a magnetic carrier in which the articles to be presented for inspection are held above, but out of contact with, the electromagnets, so that when the circuit controlling the action of the carrier is broken they will not be retained on the carrier by residual magnetism.

A further object of the invention is the provision of notched plates, one of which is movable with relation to the other, so that articles received at an angle to the carrier in the notches of the plates may be adjusted to proper position to enable them to be turned for purposes of inspection.

Further objects of the invention will be hereinafter set forth.

In the accompanying drawings, Figure 1 is a plan view of part of a machine for presenting articles for inspection involving my in- 4`5- vention. Fig. 2 is an end view of said part of the machine. Fig. 3 is a view corresponding to Fig. 2 and partially in section, showing the position of the magnetic carrierwheu it receives the articles from the conveyer mechanism. Fig. 4. is a view similar to Fig. 3 and 5 O also partially in section, showing another position of the carrier. Fig. 5 is a plan view of the carrier, illustrating the articles in the positions they are received from the conveyer mechanism. Fig. 6 is a view similar to Fig. 55 5, showing the articles brought to their proper positions in readiness to be received by the chucks for turning purposes. Fig. 7 is a side view, partially in section, of my invention; and Fig. 8 is a transverse section on line 8 8 6o of Fig. 7.

Like numerals designate similar parts throughout the several views.

Referring to the drawings, the numeral 5 designates framework of any suitable construction in which the magnetic carrier is mounted for operation. This carrier is shown as having trunnions 6, which are journaled in arms 7, keyed or otherwise secured to a rock- .shaft 8, which may be operated in any desired way-as, for instance, by a pitman 9, connected with a crank-arm 10, secured to said rockshaft, as illustrated in Figs. 1 and 7.

Designated by the numeral 12 are conveyerscrews which may be driven either intermittingly or continuously in any desired manner to advance articles held between the threads thereof to positions where the carrier may receive them.

Gearing (designated generally by dotted 8O lines at 13 in Fig. 2) is shown as one means by which the conveyer-screws 12 may be rotated in the same direction; but it is distinctly to be understood that the invention is not limited to such gearing, for other means may be employed for driving the screws without departure therefrom.

My improved magnetic carrier is designated in a general way by the numeral 14C and comprises in its preferred form a hollow rectanguiar frame. Two plates 15 15', of brass or other non-magnetic material, each plate having notches 152 for the reception of the articles to be inspected, constitute the sides of the carrier, and back of these plates are iron or other magnetizable plates 16 16/ of less width than the plates 15 15', so that their upper edges will be below the bases of the notches 152, and consequently will not come into contact with the articles to be inspected, but will have their full effect when energized to retain said articles in the notches 152. Said plates 15 15 are separated to form a coil-receiving chamber by a central core 17, around which is placed an oblong coil 18, preferably composed of insulated wire of small gage. Toinclose and protect the coil, top 'and

bottom plates

19 and 20, of brass or other non-magnetic material, are placed between the plates 16 16/, and all the parts are firmly secured together by screws 21, passing through the plates 15 15 16 16 and threaded into the core, as shown in Fig. 8. Trunnions 6 are provided with heads 22 for closing the ends of the coil-` chamber, and said heads are grooved at 22/ to receive tongues on the

plates

19 and 20, as illustrated in Fig. 7.

Spools 23, composed'of vulcanized liber or other insulating material, surround and are keyed to the trunnions 6, and the flanges of said spools bear on one side against bearings of the arms 7, and on their other sides against the heads 22 of said trunnions, as illustrated in Fig. 7. Between the flanges of each spool is a metallic contact-ring 24, and the ends of the coil 18, from which the insulating material has been stripped, are inserted within `said contact-rings, as also shown in Fig. 7.

Reduced extensions 6 of the trunnions 6 are journaled in bearings 7/ of the arms 7, and to the outer one of said extensions is secured a gear-wheel 25, actuated by means hereinafter described.

.Rock-shaft 8 is journaled in bearings 26, rising from the frame or stand 5, and, as above stated, this rock-shaft is actuated by a pitman 9, connected to crank-arm 10 by any suitable means-for instance, those illustrated and described in my application above mentioned.

Any suitable means may be utilized for energizing and denergizing the electromagnets 16 16/ of the carrier, and in Fig. 1 of .the drawings a circuit is designated by 27, said circuit having' a switch 28, by which the current may be turned on or off, as required. The terminals of the wires of this circuit are connected with contact rings 29, insulated from the rock-shaft 8, and connection `is made between the contact-rings 24 and said rings 29 by metallic strips 30, supported upon blocks of insulating material 31, secured to and projecting inwardly from the arms 7, as illustrated in Figs. 1 and 7.

For axially rocking the magnetic carrier a toothed sector 32, in engagement with gear 25 on one of the extensions 6', is employed, said sector being at the end of an arm 32', having' a hub 322 sleeved upon the shaft 8 between an end collar 33 thereof and the hub of the outer arm 7, and for actuating said sector-arm a rod 34 is articulated to a projection of the arm at one end and may be operated mechanically or-otlierwise, as desired. Projecting from a frame or stand 50 is a standard 35, in which is formed a cam-groove 36, adapted to receive a pin 37, secured to the notched plate 15. rlhis plate is provided with slots 38, through which the screws 21 pass, and when the pitman 9 is actuated to rock the carrier to the position illustrated in Fig. 3 the stud 37 of said plate will enter the camgroove 36 and will throw the plato to thc position necessary to conform to the inclined location of the nails or other articles upon the conveyer-screws 12, as illustrated in Fig. 5, and as said carrier is rocked back to the position illustrated in Fig. 6 said plate will be actuated by the cam 36 to bring the nails or other articles received by the magnets from the conveyer-screws 12 to the proper positions forV the action'of the chucks employed for intermittingly turning the articles to present them for inspection. These chucks are designated in a general way by 39 and are carried by a slide 40, as illustrated in Figs. 1 and 2 and as fully set forth in my application aforesaid.

In the operation of my invention the circuit having been established by the switch 28 or otherwise the magnets are energized and the carrier is actuated to the position illus trated in Fig. 3 to attract the nails or other articles from the conveyer-screws. As it is moved to said position the plate 15 is thrown by cam 35 to the position illustrated in Fig. 5, and the articles are received from the con veyer-screws, and after this has been accomplished the carrier is returned to normal position, where it remains during several of the inspecting periods, as stated in my former application. During this return movement the sliding plate 15 is actuated to bring the articles from the inclined position (illustrated in Fig. 5) to the straight positions, (illustrated in Fig. 6,)'where they vare held in readiness for the action of the chucks 38.

Many changes may be made in the various details of my invention without departure therefrom, and .various means different from those shown may be employed for retaining the articles upon the carrier. So, too, other devices may be employed for enabling the carrier to receive the articles in an inclined IOO position from the conveyerescrews and for bringing them to the proper positions to enter the chucks by which they are intermittingly turned.

Means different from the notches shown for the reception' of the articles may also be employed without departure from my invention.
