ADJUSTABLE SHAFT-ENGAGING MEANS.
Specification of Letters Patent.
Original application filed June 7, 1907, Serial No. 377,710.
Patented Oct. 11, 1910. Divided and this application filed November 29,
Serial No. 530,377.
T 0 all whom it may concern:
Be it known that I, FRANCIS P. Huron, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Adjustable Shaft-Engaging Means; 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, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.
My invention relates to means particularly adapted for operatively mounting the rotors of motors directly upon the shafts of any of the different sewing machines commonly used, regardless of the lengths of the short rojecting ends of such shafts and the consi erablevariations inthe diameters thereof. The invention, however, is not restricted to use in such connection as it is applicable for securing any rotatable member, such, for instance, as a pulley, balancewheel, or the like, to its shaft.
The object of my invention is the provision of a simple and efiicient device of this character, which, in addition to its adaptability for use on different lengths or diameters of shafts, as above stated, is inexpensive of manufacture, strong and durable in its construction, and capable of being easily and ipliickly applied to a shaft to look a part t ereto, or removed therefrom, without the use of tools, save a screw-driver, thus roviding apractical and useful device of this class.
The importance of my invention when used for attaching motors to the shafts of sewing machines, for which pur ose it was primarily adapted, will be rea ily appreciated by all persons who have had experience in such connection, as the shortness of the projecting ends of the shafts renders the securin of motors thereon by the use of keys, ms or the like impractical if not impossib e. A further objection, which ispresent with all other means which have suggested themselves for securin a motor. to a sewing machine-shaft, is the-iabilit of the motor to jar loose and drop from t e shaft due to the constant vibration of the machine when rimming. This together with numerous other objections which have presented themselves in the course of experimenting have made my present invention of extreme 1mportance in connection with the motor driven sewin machine art.
The invention is fully described in the following specification and while in its broader aspect it is capable of embodiment in numerous forms, a preferred .form of the same is illustrated in the accompanying drawings, in which,-
Figure 1 is a side elevation of a form of my invention attached to a sewing-machine shaft. Fig. 2 is a similar view with the outer and inner compression sleeves removed from the shaft. Fig. 3 is a central longitudinal section of such sleeves in coiiperating engagement. Fig. 4 is a side View of the anchor clamp. Figs. 5 and 6 are side and outer end view, respectively, of the compression sleeve, and Fig. 7 is a side view of the outer removable flange or ring of the outer sleeve.
This application is a division of an application filed June 7, 1907, and allotted Serial No. 377,710.
Referring to the drawings, 1 designates a part of a sewing machine head or arm and 2 the projecting end of the shaft thereof from which the usual hand-wheel has been removed. Upon this shaft is rigidly clamped a two part anchor-member or dog 3 by means of clamping screws 4. This anchor upon its inner side bears against or coacts with the bearing-boss 5 of the arm 1 of the machine and thus takes up and prevents longitudinal movement of the shaft, a feature which is of very great importance in the proper running'of the machine.
Upon the projecting end of the shaft 2 is slipped a sleeve 6, which is externally threaded, as indicated, and is shown as having its outer end provided with a head 7, which is transversely recessed for the reception of a wrench or other turning member. The sleeve 6 is provided with a double series of longitudinal slots 8, one series of which extends from the outer to near the inner end of the sleeve while the other series extends from the inner to-near the outer end thereof, with the slots of the two series alternating. The slotting of the sleeve in this manner enables it to have considerable radial resiliency to permit the sleeve to be uniformly compressed throughout its entire length to clasp, as closely as may be desired the shaft upon which the sleeve is placed.
An outer sleeve 9 incases or receives the compression-sleeve 6 and is internally threaded to correspond with the external threads on the sleeve 6. The spiral ribs or threads upon the meeting surfaces of the sleeves 69 are oppositely beveled in transverse section in such fashion that when, by the rotation of the inner sleeve,the outer sleeve being immovable,-these beveled surfaces are brought powerfully together, and the resilient sleeve 6 is, by the wedge-like action of the inclined planes compressed and caused to powerfully grip the shaft. It will, of course, be understood that during a turning of the sleeve 6 within the sleeve 9, the wedge-like or compressing action will not occur until the relative longitujdinal movements of such parts have been stopped by reason of the head 7 of the inner sleeve coming in contact with the outer end of the sleeve 9. The inner end of the sleeve 9 is intended to rest against the anchor or dog 3, and is provided with one or more projecting lugs or fingers 10, which are adapted to project within complemental notches or in'terengaging recesses 11 in the anchor. The lugs 10 preferably have a loose fitwithin the notches 11 to facilitate an easy finding of the same, and while the coacting surfaces of such parts are shown in the present instance as being smooth, the invention is not restricted in this respect as any suitable or convenient manner of interlocking the anchor and sleeve may be employed. It is evident that the anchor being securely clamped upon the shaft of the ma chine and the sleeve 9 being thus engaged with the anchor, the shaft, anchor and sleeve must always rotate together, and
also that the frictional resistance of the in terlocking surfaces of the anchor and sleeve, when the latter is acting to drive the former, Will prevent relative end motion of the two parts even should the sleeve have a tendency to slip on the shaft, this being initself an important feature.
,for use on sewing machine shafts must be provided with a shaft securing means which is adapted to be mounted upon the short projecting vends of shaftsand' must be capable of adjustment to fit and tightly grip shafts'of varying diameters, as shafts having varying diameters and different length projecting ends will be encountered in dif ferent makes of machines.
I Wish it to be understood that my invention is not limited to any specific construc tion or arrangement of the parts, except in so far as such limitations are specified in the claims.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is,
1. In an attaching device, the combination with the drive shaft, and the bearing part from which one end of such shaft projects, of an anchor detachably secured to the projected end of such shaft in abutment with the head to prevent relative endwise movements of the shaft and head, a member mounted on the shaft, said anchor and member having separable interlocking portions to cause them to revolve in unison, and means independent of the anchor for locking the member to the shaft.
2. The combination with a shaft, of a member mounted thereon, means internal of the member but independent of the shaft for clamping the member to the shaft, and anchor means detachably secured to the shaft at an end of said member and in loose interlocking engagement therewith to cooperate with said clampingmeans to prevent endwise and rotary movements of the member relative to the shaft.
3. The combination with a shaft, and a bearing part therefor, of an anchor carried by such shaft in abutmentwith suchbearing part, a plurality of relativelymovable members encircling the shaft and-capable of cooperating to lock the outer member to the shaft, said anchor and one of said :members having loose interlocking portions to cause them to rotate in unison and which coop-- erate with the member and locking means to prevent relativeendwise movements of th anchor and, member. j 4. The combination with-a shaft of a sleeve mountedon the shaft, .a second, sleeve disposed within the first sleeve, and slotted to adapt it to have uniform compression throughout its length, said two sleeves having surfaces which cooperate to effect a madial compression of the-inner sleevewhe'n the two sleeves are relatively moved, and-a member secured to the shaft at an end; of the outer sleeve and having interlocking engagement with such sleeve to .cause the sleeve and member to rotate in unison and to assist Sin preventing relative endwise movements of said member and outer "sleeve, said member also serving to wise movement of the shaft.
,5. The combination with a shaft, and a bearing; part therefor, of a .memberrclamped to the shaft in abutment with, the hearing prevent-end: f
part, a sleeve mounted on the shaft, a compression sleeve disposed within the first sleeve, said two sleeves havlng surfaces sion of the inner sleeve when the two sleeves are relatively rotated, said outer sleeve and member having complemental interlocking portions which cause the sleeves and member to rotate in unison and to assist in preventing relative endwise movements of said member and outer sleeve, substantially as described.
