MULTIPLE-NEEDLE HOLDER FOR ELECTROLYSIS.

hlcago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Multiple-Needle -Holders for Electrolysis, of 'which' the following is a specification.

y invention relates to multiple needle holders for electrolysis and has particular reference to improvements in the multiple needle holder shown and described in Patent lunziber 864,968 granted to me September 3,

The object of my invention is a multiple needle holder for electrolysis which" shall have greater Hexibility as a whole and in its separate arms than the one afore mentioned.

A further object of my invention is to lprovide a multiple needle holder having means for attaching the device to the person patient and equip the same with iniproved means for attaching it to t-he head, and auxiliary means for securing the device to the'arm or back of a chair.

' comprises a pair of to the intermediate sect`io `that movement the arm will have.

.u on the @ther objects will appear hereinafter.

The device ,comprises generally a suitable base-or support and a plurality of jointed arms attached to said support and having a needle holder at the free end of each arm.

he arms are each formed of three sections connected by universal joints. The joints are preferably of the ball and socket type and comprise a socket member arranged ends of the rst and last o `the arms and a ball formed upon each end of the intermediate section. The socket rings between which the ball is el sufficiently to give -considerable movement It is obvious the nearer the intermediate section appreaches to an alinement with the widest portion of the flared socket, the greater the ln the afore lmentioned patent l have illustrated the flare of the socket in alinement with the longitudinal axis of the first section of the arm, consequently when the rst and intermediate sections are turned at right angles to each other or thereaboutas is its usual position,

of the intermediate A further and particular object of the present lnvention is to soarrange the joint to provide sections amped and the rings are flared the recess 2 between the first and intermediate sections, as to give ample lateral movement to the intermediate section when yin the usual operative position. I also find that greater flexibility of the lower or end section of the arm is required at times to properly position the needle, without increa ing t-he length of the arms.

A further object of my invention is to improve this portion of the device. v

My invention will be more readily understood by reference to the accompanying drawings forming a part of this specification and in which, f

Figure 1 is a plan view of a multiple needle holder embodying my invention, F 2 is a side elevation of the device illustrating but two arms, Figs. 3 and t are details. Fig. 5 is a view similar to Fig. 2 illustrating but one arm and embodying a modied form of the last section and the needle holder. Fig. 6 is a detail section. of the modication shown in Fig. 5, Fig. 7 is a detail, illustrating one form of device for Aattaching the needle holder to ai chair, and Fig. 8 is a side elevation of a modiedform thereof.

Referring to the drawings, l indicates the base or support of the device which is preferably stamped out of sheet metal and then bent into the form shown in the drawings. As shown it comprises a plate portion, 2 a pair of forwardly extending arms, 33 and an upper vertical arm, 4E. The plate, 2 is riveted-or otherwise secured to 4a steel plate 5, as by the rivets, 5. rllhe upper portion of the plate 2 is slightly offset asA at 2 leaving a narrow space or recess 2 between the oifset portion and the plate, 5 for a purpose hereinafter described. Instead of forming the arm, base, 1, l may form it separately and connect it to the plate, 5 as shown in Fig. 5. To the plate, 5 .1s secured aI strap, 6 by means of which the device may be secured to the person of the patient.

6 indicates a pad ,preferably formedvof insulating material.

Tofattach the device to the head, l pro 'vide a novel spring clamp detachably secured thereto. This comprises a. curved steel spring member, 7, one end of which is detachably secured within the recess 2f and to the other end of which is secured a pad, 7. rlthe end of the spring, 7 which enters is provided with a notch, 7" which engages with the upper rivet, 5.

which is secured to the portion, 13

, angles to each other,

l 55 ranged betwen.:

secure the device to the head the pad 6 is placed against theV forehead and the pad 7 against the back of the head, the spring, 7, passing over the top. n

The'arrm 4 is provided with a socket for an electrical plug, 8 a'nd the end of the arms, 3, are connected by a bolt, 9 whichconstitutes the pivot for the needle supporting arms. n The plug, 8 is insulated from the arm, 4, and is provided with a main line wire, 11 and the separate insulated wires'12 leading to the several needles. The arms are each formed of a plurality of sections connected by universal joints and are preferably pivotally connected to the support, 1. As shown in the drawings, each arm comprises three sections, a first section, 13 an intermediate section, 14 and an end clamping section, 15 which holds the needle.- The rst section is preferably formed of sheet metal stamped and bent into the form shown and comprises the main or body portions, 13 which is turned at lright angles thereto. The socket member hereinbefore mentioned is formed upon the end, 13. of the arm and is flared in alinement with said portion and hence, at right angles to the body portion of the arm. The socket comprises the rings, 19 and. 19 formed upon the end of the arms and a clamp member, 21 respectively,

of the arm `by a bolt 22. It is obvious that with this construction the cent-ral portion, 14 will have maximum lateral movement when the portions 13 and 14 are at substantially right which is the position they assume when in use. The middle section, 14 of each arm comprises a tubular member equipped with a ball at each end,

'of which thev ball, 20, forming a part of the joint just described is one and 24 the other. These sections are preferably made telesco ic as shown, andas particularly descrl ed in the. afore mentioned patent.

In order to better position the needle, at times, I provide a joint in the lower ory end section, `15 and to this end construct the same as follows :-25 25 indicate a pair of plates each having a ring, 26 which rings are outwardly flared forming a socket for the ball, 24. The outer ends of the lates 25 are spaced apart by a washer, 2 arthem on a rivet or bolt, 28.

Intermediate of the ends, the plates are connected by a bolt, 29 whichI clamps them ony the washer,27 and the ball, 24. Pivoted to the rivet, 28 are a pair of lates, 30 havlng their ends bent as at 31 to orm a socket, for the needle holders, 32, upon which they are clamped by a bolt, 33 passing throu h said plates intermediate of their ends. arrangement the needle holder, 32 may .be placed in the desired position while main.- taining the flared soket rings, 26 1n alinethe latter of s y this ment with the section, 14. It is'obvious that perfect flexibility of the arms is secured in this manner.

Instead of jointing the vlower section in the manner just described, the needle holdery may be swiveled to the end of the section and in Figs. 5' and 6 I have illustrated an.

arm embodying this modification. In this form'the lower section, 15 is formed of a pair of plates, 50-50, each plate having a ring, 51-51, 52--52 at each end, the former forming the socket for the ball, 24 of the intermediate section and the latter forming a socket for a ball, 53 formed on or secured to the needle holder. The plates 50-50 are held apart by the stud,'54 and are clamped upon the balls, 24 and 53 by the bolts, 55 and 56 respectively The needle holder is secured in a clamp, 57 secured to the ball 53LV It is frequently advantageous to provide a support for the device instead of attaching it to the patient, and to this end I provide means for attaching it to the arm or back of a chair. .In Fig. 7 I illustrate a devicesuch as I find convenient for attaching the needle holder to the back of a chair whenoperating upon the face. This comprises a clamp 35 adapted to be secured to thejback, 36 of .a chair and a bracket 37 extending upwardly rom said clamp and bent forwardly as at 38 to extend over the head of the patient, portion, 39 having a plate, 40 secured thereto. Upon the plate, 40 are a pair of bolts, 4l which extend through holes 5 in the plate, 5. The boltsare equipped with butterly nuts or thumb nuts, 42 for securing the device thereto.

To attach the device to an arm of a chair a similar clamp may be employed, the main diderence being that the bracket, 37 is made much shorter, vand the plate, 40 is secured terminating in a depending to the upper end thereof .in a horizontal invention .what I by Let- 1. In a device .of the class Ydescribed, a

multi`le needle holder comprising a base and a plurality of needle holding arms connected thereto in combination Ywith means for detachably connecting said needle holder to the arm or back of a chair said means com risin a clamp portion, a bracket exten lng t erefrom, a plate on the vend o said bracket and means for'detachably securing the base of said needle holder to said plate, substantially as described.

2. In a multiple needle holder, a base and arm pivotally connected thereto, said arm comprising a section pivota-lly connected to said base an intermediate section pivotally `connected to the 'first said section and a jointed needle holding section pivotally connected to the lower end of said intermediate section, substantially as described.

3. In a device of the class described, a suitable base in combination with an arm pivotally connected thereto, said arm being formed of three sections, the end section comprising a pair of plates rigidly spaced apart at one end and having a two part' clamp formedA at the other end for holding the end of the adjacent section between them, a. bolt connecting said plates intermediate of their ends, a second pair of plates pivotally connected to the ends of the rst said plate and having their ends formed into a socket to receive the needle holder and means for clamping said plates on the holder,l substantially as described.

In testimony. whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
