UNITED STATES PATENT onricn LOUIS H. PERLMAN, OF NEW YORK, IL Y.

WHEEL.

Application filed December 4, 1916. Serial No. 135,072.

To all whom it may concern:

Be it known that I, LOUIS H. PERLMAN, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and' useful Improvements in Wheels; 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.

demount'able rims for. automobile wheels,

and more particularly to the type known ring to be relatively reduced in effective diameter for permitting the application and as transplit or cross cut, that is; the type wherein an otherwise continuous tire-carrying ring is transversely cut for enabling the removal of tires having inextensible beads.

The object in 'view'is 'the' provision-of l rim embodying-the features of the present invention, the operating tool being illusprior trated as applied'and in position just to the rim collapsing operation.

Patented De 16 1919 taken through a modified form of'tool re- I ceiving socket of the rim. Referring to the drawing by numerals, 11 indicates a transplit demountable rim em bodying the features of the present invention which may-best be made apparentlbyz-t a detailed description of the 'qperating'tool whose use isfacilitated'by the improved Ilm.

one of its ends fulcrumedon pivot 3 car;

of the bar is vformed cylindrical and provided with diametrically opp'ositeoutstand 1 'in the drawing, ije dicat vanl'operatingv lever which is pivotechon a shaft 2 and 'ried by a bifurcated bar 4. -The free end inglocking 5. The shaft 2 is surrounded by s coves-6, 6, arran ed at oppo v site sides of the Leverj '1 an serving las v spacers therefor. ,fllie shaft 2isi provided with a headat onegfid and a nut or other I similar heading meiiioerrat the opposite end,

a and the and between the heads of the sh other ends of the sleeves 6 are arranged links.' 7, 7 the links, being pivoted onto the" shaft in a position to'swing' freely thereon. The free end ofjeach link is bent substan-.

tially at right angles and .is preferably tapered to form a hook 8, Each hook 8 isrelatively straight, .but as will become.ap-' parent serves the purpose of an ordinary hook. The links 7 are connected near their free ends by a cross rod 9 having ahead at one end engaging one of the links an'd a,

nut 10 threaded-onto the opposite end por-' tion and engaging the other link. An appropriate washer may be employed between the nutand link as also between the 'hea of rod 9 and the adjacent link.

. Rim 11 is provided with a tongue 12 outstanding from one end and formed with a hookl3 adaptcdto enter a slot 14' formed in the opposite end of, rim 11 for receiving said hook. Thefianges of rim 11 at the. slotted end are formed with apertures 15 for receiving the hooks 8 oflinks 7. The opposite end portion of the rim 11 is provided with a radially-inwardly extendingprojection or stud "16 which is riveted or otherwise fixed to the rim. The stud 16 is formed with an axial recess overhung by a substantially annular flange 17, the flange being interrupted at diametrically opposite points by radial openings or. slots18. The

slots 18 are disposed to be intersected by a line extending transversely of the rim and are of a size adapted to permit the passage of the pins 5, the recess in the stud 16 being proportioned to receive the cylindrical lower end portion of the bar 4.

In operation, the rimll being in the non collapsed condition seen in Fig. 1, the cylindrical portion of-bar 4 is introduced into the recess in stud 16 while the lever l is'disposed to extend in a direciion transversely of the rim, as indicated in dotted lines in Fig. 3. The pins 5 arepassed through the slots'18 and then the leverl is swung to a position substantially alined with the rim,- during which movement the pins 5 are moved beneath the overhanging flange 17. Thus the bar 4 is quickly and effectively anchored to the rim. The links then are caused to engagethe opposite end portion of the rim by having the hooks 8 inserted in the apertures and the nut 10 threaded up sufficiently for tightening the links in the iven position. 1

T 1e lever 1 is offset at and provided with a terminal portion 21 adapted to receive a complemental operatingtool 221 of any appropriate length, thet l or handle 22 being formed with a seek to snugly receive the portion 21. The offset 20 enables the handle 22 to lie outside the planes of the rim -11, and offset 20 is preferably ofv sufiicient length to leave the handle 22 entirely free of the adjacent edge of the rim so as to facilitate manual manipulatinfk' The parts being assembled as above described and as seen in Fig. 1, the operator grasping .the lever; 22 swings the same through an arc of approximately 220 degrees'. The -effect of this movement is to cause the links 7 to travel through such a path as effects first a movement of that end of rim 11 'engaged'by the links inward to an extent freeing the end from engagement with hook 13, and then to move toward the bar 4 until the end portions of the rim are in the lapping position seen in Fig. 2. This movement brings the pivots for links 7 represented by rod 2 below the plane of the pivot 3 and at the opposite side from the position formerly occupied so that the pull of the rim ends incident to the tendency of the rim 11 to assumeits former condition is effectively resistedand the parts are locked in their collapsed condition. This collapsing movement results in a reduction in the effective diameter of the rim 11 so that'a tire with i-nextensible marginal beads may be applied or removed without difiiculty. The handle 22 is preferably withdrawn from its engagement with the lever during the application or removal of a tire to or from the rim 11. After a tire is removed and a new tire applied, the rim 11 is expanded to its normal position merely by reapplication of the handle 22 to lever 21 and a converse movement of the parts from that'producing the collapsed condition of the rim 11. Re

ends as it existed prior to the. collapsing of the "rim by the instrumentalities' described.

the locked-together condition of the rim The stud 16, during operation of the rim on a wheel, is accommodated by a recess in the peripheral portion of the wheel, body, not shown, .and may serve as a driver for the rim.

It is especially desirable that the locking of the bar lto the stud 16 shall'beaccom plished quickly and effectively so asto prevent loss of time and obviate'possibility of accidental disengagement. The cylindrical portion of the bar 4: is proportioned to fit snugly in the socket or bore of the stud 16, so that the bar 4: mayserve asa fulcrum post and without liability of objectionable looseness or play.

in any appropriatemanner, the said tongue being produced in the structure shown in the drawing by the provision of a separate plate welded or otherwise appropriately anchored to the webof the rim 11. Cther shapes of tongues and. other methods of con- The pro1ectmg tongue 12"may, be formed I nection therefor maybe provided as may be desired.

-It is to be noted that-the rim 11 is provided with a valve stem hole at 19 surrounded by the usual driving stud, the hole 19 being located in that end portion of the rim 11 which carries the socket provided by stud 16. An important advantage of, tfiisai' rangement arises from the fact that the distortion of the rim' when bein collapsed occurs along that end portion w ich is provided with the apertures 15, and the end portion carrying stud 16 is not relatively distorted whereby the valve stem extending.

through thehole 19 is not subjected to the strain of the shifting of a portion of the rim. In other words, the end portion of rim 11 which is provided with apertures 15 is actually swung inward with the movement of the tool as described, and if the valve stem hole 19 were provided in that portion of the rim which is thus swung, there would be a tendency both to bend the valvestem out of place and to strip material ofi of the stem incident to movement of therim end portion independent of the tire mounted thereon.

While the stud l-6 which provides the post receiving socket has been shown as one effective means of reeeiving thepost 4, other forms of sockets may be employed as for example, such asi'sseen in; Fig. 10 wherein the material of the rimvll" is stamped to form.a .stud 16' having the socket or boreprovided with the overhanging flange 17 'recei v1ng theextreme end portion of the post 4: WhatI'claim is:' 5
