Specification of Letters Patent.
Application led June 5, 1917. Serial No. 172,939.
' object is to provide a simple'device by which bil the housing sleeves of roller bearings in the rear axles or axles with dierential gearing and for similar purposes and by which the removal is quickly and easily accomplished. Other `objects and advantages will be fully explained in the following description and the invention will be more particularly pointed out in the claims. l v
Reference is had to the accompanying drawings which form a part of this application.
Figure 1 is a Side elevation of the improved tool, the handle bein raised.- Fig. 2 is a side elevation of the too at right angles to the view in Fig. l, and showing the tool in position to extract the sleeve. Fig. 3 is a plan view of the same. Fig. 4; is a view similar to Fig. 2, but showing a variation in the tool connections.
Similar characters of v to indicate the same parts several views.
The improved tool includes a lifting member 1 and gripping members 2 cooperating therewith. A lever handle 3 is provided for the lifting member 1 and a pry A is pivotally connected to the short end of the lever 3. A sliding collar 5 is mounted on the lifting member 1 and the coperating gripping members 2 are' pivotally connected to the collar 5. An adjustable lifting collar .6 is slidably mounted on the lifting member 1 and a link bar 7 is pivotally connected to the collar .6 and to the lever 3. Rack teeth 8 are formed on the lifting member 1. By means of the. liftin collar 6, the extracting of the sleeve is mae easier because the sleeve can be drawn a portion of the distance out and then the handle lowered so that the collar 6 can engage a tooth farther down on the liftmember 1 which moves freely` through reference are used throughout the ing the lever 3. This can be re eatedly done until the sleeve is removed. fter the rst lift with the lever handle, the lifting member 1s drawn up by the collar 6 which engages the rack on the lifting member. The
pry 4 is set on the upper part of the housing 9 during operation to cooperate with vthe lever 3. A pin`12 prevents the member 1 from falling out of the lever 3.
In operation, the pryre is set on the upper part of the housing. he lifting member 1 -is let down through the sleeve and the cooperating gripping members 2 allowed to descend with the lifting member as far as the colla-r 5 will let the members 2 o down. The lever 3 will be lowered to lett e members 2^ pass below the lower end of the sleeve 10. The grippers 2 are provided with lugs 11 which catch under the bottom of the sleeve 10 when the lgrippers 2 are forced outwardly bythe we ge-shaped shank of the lifting member 1. member 1 will pass up through the collar 5 without moving the grippers so that v the wedge-shape will force the grippers 2 outwardly and thus project the lugs 11 under the sleeve 10. On further operation of the lever handle 3, the member 1 will hold the lugs 11 under the bottom of the sleeve 10 and thus force the sleeve 10 out of the housing 9.
The variation shown in Fig. 4r shows the lifting member 1 without the coperating collar 6 and link bar 7, and the lifting member 1 is pivoted directly to the lever 3.
Various changes in the sizes, construction, and proportions of the several parts may be made without departing from the scope of the appended claims.
What T claim is 1. A sleeve extractor comprising a lifting member rovided with a rack formed thereon, a col ar slidable on said lifting member, cooperating gripping members pivotally connected` to said collar and provided with lugs at their operating ends for engaging a sleeve to be extracted, the lowerpart of said lifting member being wedgke-shaped for expanding said gripping mem ers, a lever pivotally connected to said lifting member, a link bar pivotally connected to said lever and to said collar for causing said collar to engage said rack, and a pry pivotally connected to said lever to bear against the housing of the sleeve.
2. A sleeve extractor comprising a lifting and expanding member, a collar slid able The shank` of the liftingv Patented May 1d, 1918. i.
