C. C. HARBRIDGE. TOOL FOR DEMOUNTABLE RIMS.
APPLICATION FILED JULY 24, 1914.

HIGAN, ASSIGNOR TO DETROIT DEMOUNT- ABLE RIM COMPANY, OF DETROIT, MICHIGAN, A CORPORATION OF MICHIGAN.
TOOL FOR DEMOUNTABLE RIMS.
Specification of Letters Patent.
Application filed July 24, 1914. Serial No. 852,781.
To all 1N2 am it may concern Be it known that I, CHESTER C. HAR- nnmen, a resident of Detroit, in the county of Vayne and State of Michigan, have invented certain new and useful Improvements in Tools forDemountable Rims, of which the following is a full, clear, and exact description.
The invention relates to tools for demountable rims and more particularly to wrenches for loosening and removing wedgelugs whereby the rims are secured on the wheelbody.
It has heretofore been the practice in some instances to provide flange-an-d-groove connections bet-ween'the nuts and the wedgelugs so that the wedge-lug would be moved positively with the nut, when the nut was turned in one direction to force the wedge into engagement with the rim, and when turned in the opposite direction to withdraw the lug from the rim. These wedge-lugs have portions fitting between the felly band and the rim and frequently become jammed in place so that considerable force is necessary to dislodge them. In other instances, no flange-and-groove connections were employed between the nut and the wedge lug and in these difficulty has been experienced in withdrawing the wedge-lugs from the nm.
The invention is designed .to provide an improved tool wherebv the lugs may be positively forced outwardly as the nut is bein turned off and toward the end of the bolt, in securing devices in which there is no flangeand-groove connection between the bolt and the lug; so that said fiange-and-grooveconnections for withdrawing the wedges may be dispensed with. The invention attains this object by means of an attachment to the tool or wrench employed for turning the nut, which is adapted to engage the inner face of the lug and to withdraw the lug with the nut.
Another object of the invention is to provide a device which may be employed on the usual form of wrench used for nuts on de- 'upon which the pulling yoke may be used.
The demountable rini illustrated comprises a felly l0, felly-band 11 thereon, and a remova le rim 12 carrying a pneumatic tire 14, all of which may be of usual construction, as well understood in the art. Bolts 15 are secured in the felly and one end of each bolt extends through an opening 16 in a wedge-lug 17. This Wedge-lug is provided with an inwardly extending portion 18 adapted to fit between the rim I2 and felly band 11 to support one side of the rim. the other side being seated upon a flange 19 on the folly band. The wedge lug 17 is pro vided with an inwardly projecting hearingportion 20 at the lower end thereof so that ,the side 21 of said lug between bearing 20 cal nut may be provided with a spherical bearing-surface 25 fitting in a correspondinglv shaped seat 26 in the lug.
The improved tool comprises a member 27 having a socket 28 therein which is formed to fit around and is adapted to receive the nut 24 and to engage it so that the nut may be turned in either direction thereby. A shoulder 29 is formed in member 27 which is adapted to abut against the outer face of the nut so that as the nut is withdrawn from the bolt, member 27, as it turns. with the nut, will be forced outwardly by the nut, thus causing member 27 to be moved longitudinally relatively to the bolt 15 as the nut is withdrawn from the bolt. Member 27 is rigidly secured to the shaft 30 of a bail or crank 30 and a handle 31 is swivelcd to the outer end 32 of the crank. By pressing the handle 31 inwardly in turning the crank 30 when a nut is held in socket 28, the nut may be quickly rotated in either direction.
A who .3 is p atal yau slid h y oun ed on the crank 30 adjacent member 27. This yoke comprises a pair of arms 3%, each provided with alug or hook 35 and a connecting portion 36 having an opening 37 therein for the shaft 30. The lug is slidable upon said shaft so that when the tool is being used to turn the nut on the bolt, it can be slipped back'on the shaft and away from the wedge-lug 17. Opening 37 is of suflicient size to permit a limited pivotal movement transverse to .the axis of the shaft to permit lugs 35 to be swung into and out of engagement with the inner face of the side 21 of the wedge-lug when the nut is being turned off the bolt. Bearing 20 is somewhat narrower than the side 21 of the lug so that the hook and lugs 36 can be swung past the bearing into engagement with the inner face of side 21 of the lug and under wedge-portion 18. lVhen the yoke has thus been shifted into engagement with the lug, which can be done after the member 27 has been placed on nut 24, as indicated in Fig. 2 and the crank 30 is turned to remove the nut from the bolt, the inner end .0 member 27, which has a shoulder 39, will engage the connecting portion 36 of the yoke, and as the nut is turned ofi the bolt, it will engage shoulder 29 in socket 28 and force member 27 outwardly with the nut. Resultantly, member 27 will force the yoke outwardly longitudinally of the bolt and hooks 35 will withdraw the wedge-lug with the nut. \Vhen the wedge-lug has been withdrawn sufficiently to release the rim or remove it from the bolt, the yoke may be disengaged from the wedge-lug by swinging it transversely to the axis of the crank shafts. When turning the nut to force the 'wedge-lug into operative position, the yoke may be swung into inoperative position as shown in Fig. 1.
The invention thus exemplifies a simple tool for removing wedge-lugs with the nuts which secure them to a wheel and which dispenses with the necessity of groove and flange connections between the nut and the lugs. The means employed for withdrawing the lugs can be quickly rendered operative when the nut is to be turned inwardly on the bolt. 7
' The invention is not to be understood as restricted to the details set forth, since these can be modified within the scope of the appended claims without departing from the spirit and scope of the invention.
Having thus-described the invention, what I claim as new and desire to secure by Letters Patent, is 2- 1. -A rim tool comprising a member having a nut-socket therein, means for turning said member, and pulling means for a wedge-lug operated by said member.
2. A rim tool comprising a member havmg a nut socket therein, means for turning said member, and pulling-means operated longitudinally of the aXis of the nut to posi-' tively Withdraw the lug with a nut in the socket.
3. A rim tool comprising a member having a nut socket therein, means for turning said member, and pulling means adapted to engage the inner face of a wedge-lug, said socket-member having a shoulder for en-- gaging said pulling means to withdraw the lug with a nut in the socket.
4. In a rim tool, the combination ofa member having a nut socket therein, turning means rigidly secured to said member, and a pulling yoke provided with'means for engaging the inner face of the side of a wedgedug said member being provided withl means for shifting the yoke to withdraw said lug with a nut in the socket.
