Prenom GONE noxious. Edward Mcride, Philadelphia, Pa. Application Deoemserzs, 19er, serial No. assale e Claim. (o1. 242.4120) invention relates to a cone and holder of 4the general type disclosed in. prior; Patent l the. main holder tor receiving and supporting a.

yarn having a conical. bore.`

In the holder disclosed. in. the. Lambach patents the auxiliary holder is slipped, longitudinally, over the main holder and is held in place by means of a, set screw. Set screvvsf present a snag."

ging hazard and removing and applying the screws involves, considerable expense in. labor and in shut-down time., w

In my prior above-mentioned patent, the auxi1- lary holder is super-imposed on` the main holder by presenting the. auxiliary to the shank. offf the main holder in a. direction normal to the. axis of said shank, instead of" slipping the auxiliaryholder longitudinally over the main holder. This. facilitated .the application and. removal. of the auxiliary holder. Y

A further improvement is shon in. my' allo'v'e-v mentioned copending. application. in Whcli the.

auxiliary holder is applied to. the shank of the main. holder in generally the same manner; but in which the set screws of my prior; patent' andv of the Lambaoh patent are dispensed with. and."

the auxiliary holder is provided with springs which can be snapped. on, or off; easily and quickly.

From the foregoing, and from the state of the art' at large, it can be seen that the manufacture and installation of pirn holders of' this type involve not only the initial cost but' also the cost of repeatedly, and relatively frecurently,l applying and removing' the auxiliary holders.

Accordingly, itis the object of' the present lnvention to produce an improved* pun or cone holder or thet'ype set forth which is less expertsive to make and, more particularly, to produce a pun holder which is less expensive to apply and. remove. p

These and other objects are attained by my' invention as set forth in the following specica.-

tion and in the accompanying drawings in which: Fig, 1 is aside-elevational view of a pim or cone holder embodying my invention.

rThe holder shown in the drawing includes. a

shank. which is. secured at the inner end. thereof to a: support. 12'..

For supporting a. bobbin or other yarn carrying devicehaying a. cylindrical bore, the shank is. provided` with two. or more bowed springs I4 which` are mounted lol'lgit'udnally` of the shank with.

their outer ends engaging the opposite ends off a through hole f6 formed in the shank and With .their inner ends freely slidable in, grooves t8" formed inthe inner end. of the shank. The inner by means of a collar 20'.

present invention. Y

I'n order to adapt the holder for receiving and retaining a cone or other yarn carrying; deviare,`

an auxiliary holder or cage, is provided. This cage, which is best shown in Fig. 6, includes a hub 22 to which the outer' ends olA auxiliary loovvedA springs 2-4 are permanently secured as at 26,. `and a disc: 28, having Teshaped lugs 3u which are" adapted to be slidabiy engaged by the slotted ends 3'24 of springs 24i. vThehub 22 is provided: with a generally wshaped kopening :is which extends from the periphery to the center of the hub-1. and which is large enough to receive the. outer end of the shankr The wall` dening opening 34 is provided with. a groove 36lf'or receiving aspring f 38 Which is adapted to engage groove 40.- at the end of shank. IU as sho-Wn in. Figs.. 2. and 9. The disc 2'8 is provided with a` keyhole opening formed.

of a 4central round portion. Il and a straight portion 44 which leads from the central opening to the periphery of the disc.

The central portion 42 of the keyhole opening is large enough to receive the shank l but the straight portion 44 is too small to receive the shank. See Fig. 3. Therefore, the inner end of the shank I0 is grooved as at 46 so as to pass through the straight opening 44 and thus permit entry of the shank into the central opening 42 of the disc. See Figs. 3 and 9.

When it is desired to use the auxiliary holder, it is merely necessary to pass the grooved portion 46 of the shank through opening 44 into opening 4G, and then to move the auxiliary cage to the left, as viewed in Figs. 6 and 9, until the groove at the other end of the shank registers with the spring 38 in opening 34. When the parts are in this position, the hub 22 is moved member located near said second end of said second support and having a keyhole opening formed therein and comprising a central portion large enough to freely receive the ungrooved portion of the shank, and an elongated portion leading from the periphery of the second member to said central portion, said elongated portion of said opening being only large enough for the passagey therethrough of the shank, at said second groove.

2. The structure recited in claim 1 in which the distance between said grooves is less than the distance between said spring and the keyhole opening in said second member.

3. A device of the character stated, a shank having a rst groove formed near first end thereof and a second groove formed nearra second end thereof, a first compressible cage carried toward the shank until the horse shoe shaped portion of spring 38 encircles the major portion of the circumference of the shank as best shown in Fig. 2. It will be noted that the distance between the grooves 40 and 46 is less than the distance between gro-ove 3E in the hub 22 and the disc 28. Therefore, when groove 40 is engaged by spring 38, groove 46 will be spaced from disc 28, as best shown in Figs. 1 and 9. In this position of the parts, the inner end of the cage can not be lifted oif the shank because the portion of the shank engaged by round opening 42 is too large for straight opening 44. At the same time, the spring 38 in hub 22 detachably engages the groove 40 at the outer end of the shank to prevent any longitudinal movement of the auxiliary cage relative to theshank and to prevent unintended removal of the auxiliary cage from the shank. It will be seen that when the holder is in the fully assembled position of Figs. 1 and 4 the auxiliary cage, formed of hub 22, springs 24 and disc 28, is freely rotatable on shank l0. This facilitates inspection of the yarn 48 carried by cone 50.

To remove the auxiliary cage, it is merely necessary to pull the hub 22 away to disengage thel spring 38 from the groove 40 and then to slide the cage, to the left as shown in Fig. 9, until the groove 46 registers with straight opening. V44 in which position the other end of the cage can be detached by moving the disc to the right as viewed in Fig. 8.

The springs 24 are preferably serrated as at 52 for better engagement with the interior of the cone which is usually made of cardboard or other frictional material.

The ends of the springs 24 are bent as at 54 so that when the springs are compressed the turned up end 54 will slide freely against the tapered surface of collar 20.

What I claim is:

'1. A device of the character stated including, a shank having a rst annular groove near a rst end thereof and a second annular groove near a second en-d thereof, a rst compressible support carried by said shank for supporting a yarn carrier havingl a substantially cylindrical bore, a second compressible support for support'- ing a yarn carriei` having a substantially conical bore, and mounting means for detachably applying said second support to said shank, said mounting means including a ilrst member locatednear said first end of said second support and having an opening leading from the periphery to the center thereof for freely receiving' said shank, a spring in said opening for detachably engaging said rst groove, and 'a second by said shank for supporting a first yarn carrier having a cylindrical bore, a second compressible cage formed of angularly bent elongated springs for supporting a second yarn carrier having a conical bore, said second cage inp cluding a hub at one end thereof, a disc at the other end thereof,` means slidably connecting said springs to said disc, there being a key hole shaped opening formed in said disc with the round portion of said opening in the center of said disc `and with the elongated, straight portion of the opening leading from the center portion to the periphery of the disc, the diameter of the center portion of said keyhole opening being large enough to freely receive the ungrooved portion of the shank and the width of the straight portion of said opening being large enough freely to receive the shank at said second groove, there being a generally U-shaped opening in said hub, and a groove formed in the wall defining said opening, and a generally U- yshaped spring in said last mentioned groove for detachably engaging said shank at said second groove.

4. The structure recited in claim 3 in which the springs forming said second cage are serrated for better engagement with the yarn carrier and in which the distance between the grooves in the shank is smaller than the distance between the keyhole in said disc and the spring in said hub.

5. The structure recited in claim 3 in which said elongated springs 'are exteriorly roughened for engagement with said second yarn carrier.

6. A device of the character stated including, a shank having a first annular groove near a first end thereof and a second annular groove near a second end thereof, a rst compressible support carried by said shank for supporting a yarn carrier having a substantially cylindrical bore, a second compressible support for supporting a yarn carrier having a substantially conical bore, and mounting means for detachably applying said second support to said shank, said mounting means including a member carried by one end of said second compressible support and having a keyhole opening formed therein and comprising a central portion large enough freely to receive the ungrooved portion of the shank and an elongated portion leading from the periphery of said member to said center portion. sa1d4 elongated portion being only large enough for the passage therethrough of the shank at said second groove.
