1 Claim. (Cl. 81-15) This invention relates to a novel and improved posed. The top of this chamber is closed by a form of tool for applying dust guard caps to dust guard cap 3, and the tool covered by this journal boxes, the novel features of which will application is used in applying this cap securely V be best understood from the following descripin place so as to tightly close the top of the tion and the annexed drawings in which I have chamber 6.

shown a selected embodiment of the invention As best shown in Figs. 1 and 2, the cap is and in which: formed of sheet metal having depending flanges Fig. 1 is a plan view of a dust guard cap with 9 adapted to engage opposite walls of the dust which the tool is to be used; guard chamber, and is also provided at its opl0 Fig. 2 is an elevation of the dust guard cap posite ends with lips Ill and H which, for the 1. appearing in Fig. 1; sake of convenience, I shall refer to hereinafter Fig. 3 is a view, partly in section and partly as the opposite ends of the cap. in elevation, showing how one end of .the dust Before this cap is placed upon the journal box, guard cap is bent; the end I0 thereof is bent to the proper form Fig. 4 is a view, partly in elevation and partly to engage an edge of the journal box, which 1 in section, showing how the tool is applied to may be done by the use of a suitable forming a journal box, this view being taken approxitool l2, as shown in Fig. 3. The cap is then mately on the line 44 of Fig. 6; put in place on top of the dust guard chamber, Fig. 5 is a view of part of the same structure with the bent end I0 in engagement with the as appears in Fig. 4 and showing the tool after adjacent edge 13 of the journal box and with 20 it has completed its operation; the other end H overlapping the opposite edge Fig. 6 is a view approximately on the line 66 hi of the journal box, as plainly shown in Fig. 4. of Fig. 4; It will be seen that this end H. is formed so Fig. l is a view approximately on the line 'l--'| that it overhangs the edge 14 and is inclined of Fig.5. downwardly at a decided angle.

Various forms of dust guard caps have been I then place on top of the cap a tool formed devised to prevent the entry of dust into the according to my invention and which comprises dust guard chamber of journal boxes, and such a body l5 formed of spaced bars l6 having bedust guard caps have been more or less successtween them at one end a hook I! which may ful.

The

This journal box with the head so that the head may be adjusted receives and is supported by the journal 3 of a lengthwise of the brace to engage flanges at difwheel 4, the usual bearings for the journal being ferent distances from the tool.

guard i of any suitable construction may be dis- I believe that the operation of the tool will be plain from the above description, but it may be summarized briefly as follows:

First the cap is bent at one end III, as indicated in Fig. 3, after which the cap is placed in position as shown in Figs. 4 and 6. Then the tool is placed in position with the body contacting with I the cap and with the relatively fixed hook IT in engagement with the end l0 which has been previously bent to closely lit the adjacent edge" 13 of the journal box. The head 23 is then brought into engagement with the inner surface of the flange 24 on the wheel 4, and finally thehandle Z6 is moved downwardly so that the hog gpw n bend the end ll of the cap tightly into engage ment with the adjacent edge lg to; the journal box. The spacing of the hooks J] "angjgg such that the two ends l0 and H will clamp the dust guard cap securely and tightly to the jo n nal box. There are several standard 's'izes'of journal box, and enough holes l9 may be pro; d t a the di i n b we n t b s m be v rie and 2 1 ih' w ma h s w t a sta dar c ns m t e h a i m n th h es'and ins a on n lni form e justment to use when dealing with a iew predetermined standards, although, of course, it will be nder oo tha Other fo ms o ad li ime m b sed h r fe ed d ei b a wii e daar m t e .011 91 pm n e iq Du i he??? pression of the handle 26, the brace 22 will prevent the cap and tool from moving upwardly and will thus aid materially in providing a tight engagement of the cap and journal box.

I claim:

A tool for applying a sheet metal dust guard cap to a journal box supported by a flanged wheel, ls aid'tdo l comprising a body having a surface adapted to contact with said cap and having a fixedhoph atone end adapted to engage a bent endofftheoap'a; f hold it against an edge of said box, a brace secured to the body and having a head adapted to engage the interior of said flange to 'forcesaidsurface of the body against the cap and thus force the cap against the box, and a second hook pivoted to said body adjacent the thereof and movable towards and away from said box, the distances between said fixed hook a 'ndsa id pivot and'the distance between said pivot and said pivoted hook being such that when said pivotdihook is moved toward said box it may bhdthe other'en'd of'said 'cap' against another edge of the box.
