ALFRED H. WEISS, OF WILMETTE, ILLINOIS, ASSIGNOR TO KELLOGG SWITGHBOARD AND SUPPLY COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

SWITCHIBOARD-PLUG.

Application filed May 17,

To all whom it may concern:

Be it known that I ALFRED H. WEISS, a citizen of the United tates of America, and resident of Wilmette, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Switchboard-Plugs, of which the following is a specification.

My invention relates to improvements in plugs, and more particularly to switchboard plugs employed in telephone switchboards for connection purposes. 1

The usual form of switchboard plugs is provided with a main body portion, which body portion is provided with a protective sleeve of suitable insulating material and held against displacement or movement upon the body of the plug by means of a small screw which passes through the sleeve and screws into the body of the plug. This form of fastening necessitates the machining of parts as to drilling and tapping, thus adding to the cost of manufacture.

It is often necessary to change a damaged plu or to change a damaged switchboard cor for another, and with the usual method employed the screw which holds the protective sleeve in place, bein small, is apt to be lost. The screw is also ard to handle due to its smallness and requires considerable time to remove and replace the same, thereby making the repairin of switchboard plugs slow and tedious. apid repairs are essential intelephone switchboard work so as not to tie up any cord plugs for any length of time when makin repairs. YVith the plug of my invention, a 1 this amount of extra labor and time is eliminated.

An object of my invention is to construct a plug in which means is provided in the form of a split rin which rests in a roove in the forward en of the body portion of the plug to retain the protective sleeve in place on the body of the plug, thus doing away with the small screw which is almost universally used for holding the protective sleeve in place.

Referring now to the accompanying drawing, I illustrate several forms of my invention in which like reference characters in Specification of Letters Patent.

Referrin now more in detail to my invention as illustrated and more particularly to Figs. 1, 2 and 5, the plug comprises a hollow body portion 2 havm an extension 3 extending from one end of the body portion 2. The extension or sleeve of the plug 3 has an opening which extends the length of the said sleeve 3 and is of a size to receive the sleeve 4:, which sleeve is of'suitable insulating material. A stem 6 of a size to pass through the insulating sleeve 4 is provided,

parts, and in the end of the'said stem 6 being threaded to receive the plug tip 5 of the plug, which tip 5 engages the tip contact of the spring jack, and the sleeve 3 of the plug being a apted to engage the sleeve of the spring jack, as is well understood. The stem 6 is provided with an enlarged portion 8 which is insulated from the body portion 2 by means of'an insulated sleeve 9. This enlarged portion 8 of the stem 6 is provided with a binding screw 10, which screw 10 has screw threaded engagement with a tapped hole in a the said enlarged portion 8. The binding screw 10 is adapted to hold the tip conductor of the cord in electrical contact with the ti stem 6. A ring of insulation 11 is passe between the sleeve portion 3 and the tip 5 to insulate one from the other. The body portion 2 has its wall partly cut away to form an aperture 12 so that the bmdmg screw 10 .is accessible therethrough. Surrounding the body portion of the plu 1s a protective sleeve 13 of suitable 1ns ti/1 11 material, such as fiber or hard rubber, who

is slipped over the body portion 2 of the '0. F. WELDON. MECHANICAL INKING APPARATUS. APPLICATION F ILED MAY 26,1921.

MECHANICAL IN KING APPARATUS.

Specification of Letters Patent.

Patented Dec. 27,1921.

Application filed May 26, 1921. Serial No. 472,661.

To all whom it may concern:

Be it known that I, CHARLES F. WELDON, a citizen of the United States, residin at Delavan, in the county of Walworth, S tate of Wisconsin, have invented a new and useful Mechanical Inking Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to automatic apparatus whereby the ink within the fountain of a printing press will be thoroughly agitated at all times and equalized in such a manner that it will be uniform in consistency, and uniformly distributed throughout said fountain, thereby insuring adhesion, of the ink to the fountain roller uniformly.

A further object is to provide a transversely disposed shaft, disposed above the ink fountain, said shaft having longitudinally movable thereon a carriage, which carriage is provided with an ink agitator. Also to provide the carriage with mechanism 00- operating with oppositely arranged spiral grooves on the shaft, by means of which grooves the carriage and agitator aremoved longitudinally on the shaft.

A further object is to provide tripping fingers disposedadjacent the ends of the transversely disposed shaft and cooperating with mechanism on the carriage for reversing the direction of movement of the carriage and agitator.

A further object is to provide means whereby the agitator will be differently positioned during its reciprocation.

With the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawings, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings Figure 1 is a top plan view of the ink fountain, showing the inking apparatus applied thereto.

Fig. 2 is a side elevation of the ink fountain showing the ink stirring device therein, and the ink stirrer frame in raised position in dotted lines.

Fig. 3 is a sectional view taken on line 33 of Fig. 1.

Fig. 4 is a detail perspective view of the stirrer.

Referring to the drawings,'the numeral 1 designates the fountain of a printing press in which fountain is rotatably mounted a fountain roller 2, in such a manner that as it revolves ink from within the fountain will be taken up thereon and transmitted to the printing mechanism in the usual manner. It has been found that ink within the fountain is not equally distributed and of uni form consistency, therefore to overcomethis objection a stirrer 3 is provided, which stirrer is slidably mounted on a carriage 4 which moves longitudinally on a feed screw 5 which is rotatably mounted in bearings 6 of the pivoted frame 7. Feed screw 5 is provided with a bevel gear 7, which gear meshes with a bevel gear 8 operated in any suitable manner from the main drive mechanism from the printing press in such a manner as to constantly rotate in the direction of the arrow a. The carriage f has mounted in bearings 9 a shaft 10, which shaft is preferably in parallel relation with the feed screw 5 and is adapted to be rocked as the carriage approaches the ends of the feed screw for actuating mechanism which will reverse the direction of movement of the carriage and consequently reverse the stirring action of the stirrer 8. The shaft 10 at one end thereof is provided with an arm 11 having alug'lQ with which lug the finger 13 located adjacent one end of the feed shaft 5 engages when the carriage reaches that end of the feed screw 5. When the finger 13 engages the lug 12 the shaft 10 is rocked in its bearings until the feed screw engaging finger 14: is forced into the feed groove 15 as shown in Fig. 1, and as the feed screw 5 rotates in the direction of the arrow (4, the carriage 4; will move in the direction of the arrow 5. When the finger 14 is in engagement with the feed groove 15, said finger is held in engagement with said groove by means of the spring 16 which cooperates with the pivoted bar 17, which is pivoted as at 18 to a disk 19 carried by the shaft 10 and slidably mounted in a pivoted bearing collar 20 pivoted to the side of the carriage as at 21. The holding action is accomplished by the pivotal point 18 passing between the center of the shaft 10 and the pivotal point 21 untii the disk 19 is limiter in its rotation by engagement of the linger 14 with the feed groove "When the arriage reaches the other side of the feed screw 5 the tripping finger which is carried by the shaft 5 will move into engagement with the lug carried by the arm 52 iwhich is secured to the shaft and force said arin 91 i upwardly thereby rocking the sl 1; 10 and moving the groove engaging v er into engagement with the feed 'roove 26, which feed groove will as the reed screw 5 revoive 1e carriage to be reversed in its operation and movedto the othe end of the fountain 1. The above is a co nuous one and it will be r 3 r re fountain 1 r the ink therein stantl tirred hence the ink will be 'maintained at a uniform consistency and prop eriy fed on the fountain roller 2; feed 2:; is in engagement with the feed groove 26, tile spring 16 and the shaft 17 are in the positions shown in Fig. 2, thereby main ning; the finger in close engagement with 0 ing displacement of the saline.

The stirrer 3 is provided with reanvardly and outwardly extending curved deflecting; members 527, which members during the reciprocation of the stirrer deflect in the direction. of the fountain roller 2 so that it will readiiy feed unto said roller immediately following the stirring operation. Extending rearwardly s "er 3 is an integral arm 28, the rear end of which is provided with slot 29 through which slot a screw 30 extends. it willbe seen that'by providing slot 29 that the stirrer 3 may be moved toward and away from the fountain roller 2. To accomplish the above bar is slidably' mounted cause t to the oth r in such in bearings 32 in the upper side of the carriage i, the forward end of which is pivotaliy connected as 33 to i 3 awn 3 ot the lever 35. Lever 35 has its pivot-ally connected as at 36 to the stirrer and its arm 37 pivotally con nected at 38 to the arm 39 carried by the s1 tit 10. it will be seen that as the di-- rection of movement of the carriage t is changed at the ends of the strokes that the stirrer will be positioned differently in as relation to the fountain roller 2 thereby positioning the stirrer so thatduring its ll move from one 1* ll be con the ink -iroin the 7 an 7 eo-1. 21s

reciprocation it will not move throughthe same part of the ink fountain 1 but will be differently positioned, thereby insuring uniform and thorough stirring of the ink throughout the fountain.

Frorn the above it will be seen that air ink equalizer is provided which is simple in construction and one wherein the parts are reduced to a minimum The carriage iis provided with a plate 40 having a notch 41 therein in which notch the fiangedQ of the pivoted frame is received. Plate d0 forms means for guiding the carriage l in its reciprocation. v i
