R R. DUNBAR HOLDER CONSTRUCTION Jan. 20, 1959 2 Sheets-Sheet 2 Filed Dec. 17, 1956 2 1 r w A i w 2/? Ill 4 HOLDER CONSTRUCTION Robert R. Dunbar, Massillon, Ohio Application December 17, 1956, Serial No. 628,861 15 Claims. (Cl. 279-56) 7 My invention relates generally to a holder construc' tion and more specifically toa holder construction adapta- 'ble for use in holding a greatnumber of difierent types and sizes of articles for a multitude of purposes; Still more specifically, my invention relates to a holder construction which telescopically receives the end portion of the article to be held therein, and has means for centering said article and adjustable compressive means for secure ly holding the same. 1
Certain prior holder constructions have included a sleeve having a threaded. end portion and an internally threaded collar telescopically received over said sleeve end portion. Further, a hollow cylindricalresilient member has been received between the sleeve end surface and a generally radially extending internal surface of th collar with one of these-surfaces being angled so that,
by tightening, the collar on the sleeve, the dist'ancebetween the surfaces is reduced, thereby, with the cooperation of the angled surface, compressing the resilient member inwardly to reduce the inner diameter thereof and tightly gripping an article received in and extending from the sleeve'through the collar.
One of the difiiculties with these prior constructions/is that no centering means is provided for the inner end of the article being held in the holder. Thus, even though the resilient member tightly grips the article in the holder, the .articleimay-extend from the e'n'daofthe holder at various angledpositions in relation'to the longitudinal axis ofthe holder.
This prior holder'construction has beenlmodifiedin an efiort to overcome this problem of not having a centering means forv the inner end of the article. ;This has been done by either providing'a bushing within the sleeve or forming the inner diameter of the sleeve just slightlylarger than the outer diameter of the article being held. v This has solved the centering vproblem but in doing so has provided the problem of nonve'rsatility'; That isfto say, the size of the article being held; by the holder must be one particular size for one particular holder, so that if the outer dimensions of the articles to be held are changed, additional holders are required, since one holder can only accommodate and center one exact size of article. v e
I It is therefore a general object of the present invention to provide a holder construction which overcomes the heretofore discussed difliculties and disadvantages of the prior constructions. 1 It is a primary object of the present invention to provide a holder constructionin which the. articlebeingheld is automatically centeredin' the holder- It is a further objectof thepresent invention to-provide a 'holder construction in which; any of a number of size articles may be held in any given sizeof holder with the holder centering: means. being 'automaticall'y, op-
erable in every case. It is still a further object ofthe presentinvention to pro- 2,869,883 Patented Jan. 20, 1959 vide a holder construction incorporating an adjustably compressive member and an automatically operableselfcentering" means.
' It is an additional object of the present invention to provide a holder construction which may be selectively fabricated to automatically urge the article being held in an axial direction while the holder is being adjusted to securely hold said article,
It is also an object of the present lIlVCHtlOll topro vide a holder construction which may be selectively fabricated to automatically urge the article being held in either axial direction while the' holder is being adjusted "to securely hold said article.
It is still an additional object of the present invention to provide a' holder construction which may be incorporated ina cigarette holder and which in a particular form may be adjusted to automatically permit any pre-- determined amount of fresh air tomix with the cigarette smoke; therebycooling and diluting said smoke.
- Finally, it is an object of the present invention to provide a holder construction which satisfies all of the above objects and provides the advantageous features thereof,
' yet is relatively simple in construction.
These and other objects are accomplished by the parts, constructions, arrangements, combinations and subcom binations comprising the present invention, the nature of which is set forth in thefollowing general statement,
preferred embodiments of which -illustrative of the best 'mode' inwhich applicant has contemplated applying the principles-are set forth in the following description and illustrated in the accompanying drawings, and which are particularly and distinctly pointed out and set forthin 1 the appended claims forming a part hereof. y
In general terms the improved holder construction comprising the present invention may be stated as including amain'body member having an axially extending hole" formed therein, anda collar member axially adjustably and telescopically mounted on-the main body member surrounding at least: a part of the main body =member-and saidhole. 'The main bodymember' terminates in a generally radially extending surface atone 1 end of the hole and a portion of the collar extendsgenerally radially inwardly generally in axial alignment with and axially spaced from themain body radially extending surface, providing acollar generally radially extending surface.
'Tlie holder construction further includes a resilient ring, preferably a rubbefor plastic O-ring which is po-- sitioned between the main body and collar generally radially extending surfaces. Also, at least one of :the main body and collar surfaces are angled with respect to. a -p'lane perpendicular tothe longitudinal axis of the main bodyehole, so that whenthe collar is adjusted, moving the collar surface closer to the main body surfact, the resilient .ring is compressed inwardly reducing the inner diameter of the ring and causing said ring to grip an article extending into the main body member hole. y
Still further, ,it is preferred that the main body member is provided with an inwardly tapered or generally conical wall portion around a portion of the hole spaced ward said centering means. body surface tapers from themain body hole inwardly ber-and opening into the main body hole.
a ring, as the distance between the main bodysurface and the collar surface is reduced, the resilient ring will not only be compressed a reduce the inner diameter thereof but will also be moved in an axial direction .toward the main body centering means, thereby urging .an article held in the holder in an axial direction to- Further, when the main in a direction away from the resilient ring, as the dis- ;tance ,between the main body and collar surfaces is reduced, the resilient ring will not only be compressed to reduce the inner diameter thereof, but will also be moved in a'direction away from the main body center- ,ing' means, thereby urging an object being held in the holder in an axial direction away from said centering means. Finally, when the holder construction comprising the 'present invention is incorporated in a cigarette holder,
a vent opening may be provided through the collar, opening inwardly at the collar surface adjacent the resilient ring. Further, a vent opening may be provided extending from I the main body surface adjacent the resilient ring, through a portion of the main body mem- Finally, to form a cigarette holder the main body hole must extend completely through the main body member.
Thus, the resilient ring will normally close the main body and collar vent openings, but as the distance between the main body and collar surfaces is reduced compressing the resilient ring inwardly and reducing the inner diameter thereof, an increasingly greater amount of the vent openings are exposed. Therefore, when a cigarette is retained in the holder, by selectively adjusting the holder, a predetermined amount of air may be mixed with the cigarette smoke, said air being received through the vent openings.

-, .One embodiment of the holder construction comprising the present invention is shown in Figs. 1 through 5, inclusive, incorporated in. arnachine tool chuck. Such a chuck construction would normally be used for ho1ding and rotating relatively small articles so that machining operations can be performed thereon.
As shown in Figs. 1 through 5, the holder construction in this case includes a main body member, generally indicated at 10, a collar member, generally indicated at 11, and a resilient ring, generally indicated at 12. The main body memberlfland collar member 11 are preferably formed of a metal, such as steel, and the resilient ring may be preferably molded from rubber or plastic.
The main body member 10 is preferably-formed with a mounting portion 13, in this case of slightly reduced diameter, which mounting portion may be received in any conventional chuck normally used on machine tools or may be provided with any other usual fastening means. It is preferred that the entire main body member 10 is formed generally cylindrical in configuration, inwhich case the mounting portion 13 would be generally cylindrical; however, it could be formed of other cross-sectional configurations which, in a particular case, may be more convenient for mounting'the same on a normal machine tool chuck.
The main body member 10 also includes a holder, portion 14 which terminates in an angled or tapered end portion 15. Holder portion 14 also is provided with a centrally located axially extending opening. 16 extending from end portion 15 inwardly.
Opening 16 includes a generally cylindrical portion 17' extending from end portion 15 inwardly and terminates in a tapered or conical portion 18. Conical portion '18 provides centering means for the holder construction as will be hereinafter more fully described.
The end surface 19 of holder portion 14, which extends from the outer circumference of the end portion 15 to opening'l, in this particular form of the present invention is tapered from opening 16 outwardly in a direction toward resilient ring 12, so thatholder portion 14 'isof greater axial length; at its outer circumference than inwardly at the edgexof opening 16. The outer surface ofend portion 15,0f, holder portion 14 is, preferably provided with threads 20 forthe threaded reception of collar member 11 telescoped over end portion 15. f
Collar member 11 is also generally cylindricalin configuration and includes the threaded portion 21,,the preferably recessed portion 22 and the generally radially inwardly extending portion 23. Collar member 11 is received telescoped over end portion 15 of holder portion 14, with the threaded portion 21 engaged with the threads 20 on holder portion 14.
Recessed portion '22 extends from threaded portion 21 axially outwardly and is provided. at'the inner circumference thereof with an arcuate recess 24, preferably extending from the outer circumference of end portion 15 of holder portion 14 radially outwardly. Recess portion 22 terminates axially outwardly in the radially extending portion 23, with portion 23 extending generally radially inwardly to a diameter substantially equal to the diameter of the cylindrical portion 17 of opening 16.
Thus, a pocket is formed partially by collar member 11 and partially by the end portion 15 of mounting portion 13, said pocket being formed at the central portionthereof .by. the arcuate recess 24, at the outer side by the generally radially extending portion 23 and atv the inner side 'by the taperedQend surface 19. The resilient ring 12 is preferably provided with a normal inner diameter equal to or slightlylarger than the charm teter; of cylindrical portion 17 of opening716 and an outer diameter substantially equal to the maximum 1 diameter of the arcuate' recess 24,
' Resilient ring 12.is. positioned'normally in the arcuate recess 24 of collar member 11, as shown in Fig. 4. Also,
In use of the machine tool, chuck, shown inv Figs. 1' through 5, the article to be held is received through collar member 11, resilient ring 12 into opening 1160f main body member 10, said article being represented by broken lines in Fig. 5. The inner end of the article'is positioned abutting the conical portion 18 of opening 16, thereby centering the inner end of thisarticle within opening 16.
Thereafter, collar member 11 is rotated in reference to main body member 10, thereby gradually telescoping a greater and greater amount over main body member 10, so that the axial distance between the tapered end surface, 19 on main body member and the radially inwardly extending portion 23 of collar member 11 is decreased. This forces resilient ring 12 generally radially inwardly along the tapered end surface 19 between surface 19 and the radially extending portion 23 of collar 11, since the axial length of the arcuate recess 24 of collar member 11 is decreased, .as shown in Fig. 5.
However, since the radially extending portion '23 of collar member 11 is moved axially towardthe tapered end surface 19 of main body member 10, not only is the resilient ring moved generally radially inwardly, decreas- 4 gripping the article, it will at all times urge the. inner end of the article more tightly against the conical por tion 18 of the main bodyopening 16.
Thus, the holder construction comprising the present inventiongwhen incorporated in a machinetool chuck,
as shown in Figs. 1 through 5, will not only tightly grip an article in the chuck, but will also insure centering of the article in the chuck.
. vMany variations may bev made in the construction shown in Figs. 1 through 5 .without departing from the principles of the present invention. Thus, it is not intended to limit the principles of the present .invention to the exact construction shown therein.
For instance, the opening 16in main body member 10 may extend completely through-the main body member and as long as an inwardly tapered portion is provided therein spaced from the tapered end surface 19, the advantageous centering provided by the. present invention will still be accomplished. Further, the threads 201011 the main body member 10 which are engaged by the threaded portion 21 of collar member 11 need not necessarily be on the outer circumference of the main body member; for instance, the main body member could be formed with' a flange portion overlying collar member 11, with the portion having threads spaced radially inwardly therefrom. 1
When the holder construction is formed, as shown in Figs. 1 through 5, so that the resilient ring 12 moves axially inwardly in reference to conical portion 18 of opening 16', the radially inwardly extending portion 23 of collar 11 may be formed at various angles, depending on the inward compression desired of resilient ring 12. Also, the particular angle that this radially inwardly extending portion 23 is formed will'somewhat afiect the amount that resilient'ring 12 moves axially toward the centering conical portion 18 of opening 16.
In the second embodiment, shown in Figs. 6 through 9, the holder construction comprisingthe present invention is incorporated in a cigarette or cigar holde'r. Referring to Figs. 6- through 9, the cigarette holder includes a'main body member generally indicated at 110, a collar member generally indicated at 111, and a resilient ring generally indicated at 112.
a usual cigarette holder mouthpiece, preferably formed of hard molded rubber or plastic, and-isthreadably received telescoped within the end of holder portion 114.
Holder portion 114 is preferably formed of aluminum and collar member 111 is preferably formed of aluminum or brass. It should be understood, however, that it is not intended to limit the construction to these particular materials.
As in the first embodiment, the holder portion 114 is provided with a centrally located axially extending opening 116. However, in thisycaseopening 116 extends completely through holder portion 114 :and communicates with a centrally-located axially extending opening 126 formed completely through mouthpiece 125, as shown.
Opening 116 again includes a generally cylindrical pormg 116 than at its outer circumference, as shown.
Main'b ody. member is again formed with the threads 120 on the outer'circumference thereof adjacent the tapered end surface, and collar member 111 is again provided with the threaded portion 121, recess portion 122 and generally radially inwardly extending portion 123. Also, collar member 111 is again preferably formed with the arcuate recess .124. I
'The resilient ring 112 is again. mounted received in the arcuate recess 124 between the tapered end surface 119 of main body member 110-and the radially inwardly extending portion 123 of collar 111. In this second embodiment, however, at leaSt one opening 127 is formed through the radially inwardly extending portion 123 of collar member 111'adjacent the edge of the arcuate recess 124, so that this opening. is normally closed by resilient ring 112.
Further, an opening 128 is formed at an angle to the longitudinal axis of main body member 111) extending 111 is rotatedtelescoping it a greater axial distance over main body member 110, the distance between the tapered end surface. 119 on main body member 110 and the radially extending portion 123 on collar111 will be decreased, causing resilient ring 112 to be compressed inwardly and at the same time causing it to move radially inwardly along the tapered end surface 119. In this case, however, since the tapered end surface 119 isformed so that the holder portion 114 is of greaterlength at the edge of opening 116 than at'its outer circumference, resilient ring 112 will not only decrease in inner diameter but will also move axially awayfr'om the conical portion 118 in opening 116.
Thus, when a cigarette is received through collar 111,
resilient ring 112 and through the opening 116 of main body member .114), as shown in Fig. 9, the inner end thereof will abut the conical centering portion 118 of opening 16 and will center the cigarette in the holder. Further, as collar 111 is tightened on main body member 1111, the resilient ring 112 will be compressed in wardly'to tightly grip the cigarette, and at the same time ring 113. will be moved axially away from conical por tion 118, thereby urging the inner end of the cigarette away from this conical portion.
The main body member 110 is provided with a mouthpie'ce125 and a holder portion 114. Mouthpiece is This movement of the inner end of the cigarette. away from conical portion 118 'preventsany moisture :or tars, which may collect at this inner end of the:
toward or away from the centering means.
the present invention. section it provides minimum contact with the main body cigarette while it is being smoked, from causing this inner end to adhere to conical portion 118. Thus, when the cigarette. is finished it is only necessary to loosen collar 111, permitting resilient ring 112 to move outwardly away-from the'cigarette and the cigarette will be free to drop from the holder.
A further feature of this second embodiment is provided by the openings 127 and 128 in the collar 111 and main body member 110, respectively. As shown in 'Fig. 6, when the resilient ring 1 12 is in its normal position, the openings 127- and 128 are'substantially closed.
However, as collar 111 is tightened on main body member 110, moving resilient ring 112 radially inwardly, an increasing amount of openings 127 and 128 is exposed. Thus, when the resilient ring 112 is moved to itsextreme radial inward position, openings 127 and 128 are virtually completely opened, providing a completely open passage frm opening116 in main body member 110 to the outer air.
Thus, by selectively adjusting-collar member 111 and thereby selectively adjusting resilient ring 112, it is possi- 'ble to permit predetermined amounts of air to mix with the cigarette smoke before this smoke enters the mouthpiece 125 of the holder. In this manner cigarette smoke of any degree of mildness and also smoke which has been cooled by being mixed withoutside air may be provided.
In this second embodiment, where the holder construction is formed for moving the article, in this case a cigarette, axially away from the conical centering portion 118 of opening 116, it is necessary to angle the radially extending portion 123.of collar member 111 from the inner opening of this radially extending portion in a direction toward resilient ring 112, so that as resilient ring 112 is compressed inwardly, it may also move axially away from the conical centering portion 118. This permits resilient ring 112 to move the inner end of the cigarette away from conical portion 118 as ring 112 is being compressed inwardly to tightly grip the cigarette.
A further modification may be made in the second w embodiment by toughening the inner surface 129 of the radiallyextending portion 123 of collar member 111, such as forming a series of serrations thereon, as shown in Figs. 6 and 9. ..This roughness on surface 129 will tend to grip the resilient ring 112 so that as resilient ring 112 is compressed inwardly, it will tend to roll rather than slide on surface 129, and will thereby move the inner end of the cigarette a greater distance from conical portion 118 of main body opening 116 than if such roughness were not provided.
Thus, according to the principles of the present invention, a holder construction isprovided which contains a positive centering means, that is, the conical portion in the main body opening. ,This centering means is automatically operable despite the size of the particular article being received in the holder.
Further, the holder construction of the present invention may be adapted to urge the article being mounted in the holder in either axial direction, that is, either The direction of movement is dependent on the particular angle formed on the tapered or angled end surface of the main body member.
The particular construction of the resilient ring shown,
that is, an O-ring having a circular cross section, pro
vides many advantages in the holder construction of Because of its circular cross and collar member surfaces which are moved together .to compress this ring inwardly. V
lhus, when this O-ring is compressed axially it will not only be reduced in inner diameter but will also be reduced in outer diameter. In this manner when the holder construction is formed for moving the article heldtherein in an axial direction as the holder is being tightened, the resilient ring, because of its configuration, will provide thisaxial movement.
A further advantage of providing the resilient ring as an Q-ring having a circular cross section is that, because'of 'thecircular cross sectionof the ring, a minimum of contact is made with the article being retained in the holder when the resilient ring is compressed inwardly. Thus, in the first embodiment, shown in Figs.
1 through 5, when the holder construction is formed so that the resilient ring urges the article being retained in the holder toward the conical centering means thereof, because of this minimum contact of the ring with the article, the ring may slide on the article without damaging the ring. I g
Also, in the second embodiment shown in Figs. 6 through 9, when the innersurface of the collar member radially extending portion is roughened it is necessary that the cross section of the resilient ring is substantially circular so that this ring can roll in the manner hereinbefore described. A cross section of resilient ring having sharp corner configurations would not permit this tendency to roll as described.
It should be understood, however, that it is not intended to limit all of the features of the present invention to use with a resilient ring ofcircular cross section. For instance, the-self-centering feature of the present invention is not in any way dependent on the configuration of the resilientring.
Further, it is possible to provide a certain amount of axial movement -'of the article being retained in the holder during tightening of the holder using resilient rings of. other cross-sectional configurations. It has been found, however,tl'1a'tthe.optimum results can be obtained from theholder construction comprising the present invention by use of this. circular cross section ring, and for this reason sucha circular cross section ring is preferred.
Finally, when the holder construction of the present invention is incorporated in a cigarette holder, avent means maybe providedin this holder which may be A used for brevity, clearness and understanding, but no unnecessary limitations are to be implied therefrom, because such words are used for descriptive purposes herein, and are intended to be broadly construed.
