bob andy vice versa l/Vithy the ;t'oregoing jand other objects in `view which will appearas the description proceeds, the invention resides in the combination and arrangement Vof parts and in the details of construction hereinafter deeasily changed from a chalk line t'o a plumb i scribed jandclaimed, it being understood that changes inthe precise embodiment of the invention herein disclosed may be made within the scope of what is claimed Without departing :from the spirit of the invention. In the accompanying,drawingsze- Figure 1 represents a side elevation of the device shownready for use as a plumb bob; Fig. 2 is a longitudinal section thereof;

Fig. 3 is a longitudinal section taken in a plane at right angles to Fig. 2 showing the device ready for use as a chalk line;

Fig. 4 is an enlarged detail section showing the surplus chalk remover; and

Fig. 5 is adetail sectional view showing the connection of the top of the chalk container with the body portion thereof.

In the embodiment illustrated a cylindrical chalk container 1 is shown having a removable top 2Vsecured by a pin and groove connection 3 and havingv a central aperture for the passage of the chalk line 10.A This cover 2 has depending from its inner face a surplus chalk remover 5, shown in the form of a small cylinder having a removable closure 6 at its lower end being preterably in the form of a cap threaded thereon and having a central opening 7 forthe passage of the chalk line 10. This chalk remover 5 is filled with smallfballs or rollers, large size shot being suitable for" this purposeV such as isrshown atS so that When the cord or line 10 is drawnV through saidvballs the `chalk will be wiped off leaving just a sufficient amount to make a proper mark. The container 5 is provided with a plurality of perforations 9 in one side wall thereof to permit the chalk which collects from the line to be sitted out therethrough and prevent clogging of the container. `The container 5 is located above the chalk line in the container 1 so that'there is no diliiculty in sifting` out the chalk throughfthe apertures therein; f'

Ay similar remover 5?v dependsfrom the bottom ofthe containerv 1 below Whichvis a skirt 11 in which said containerla is housed.

f The'remover 5 which depends from the ont'ojthe' reel 20 while the remover 5a wipes ofi', surplus chalk before the line is used for the purpose to which it is intended to Wit making a line. Y l

vtop 2 of vcontainer 1 wipes oithe surplus 'y chalk from the line 10 before it is ywound Theskirt 11is provided at its lower edge i at diametrically opposite points with bayonet slots 12 designed to receive the laterally extending p'in's 16 carried by a plumb bobl.

This pin and slot connection operates to hold the plumb bob 15 engaged with the skirt 11 which is connected with the casing 1 is designed to be used as a plumbbob suse pended from the line l0, saidline having'a' yknot or other means tor securing it beyond the bottom of the container 5". .i

The removable top 2 has a grooveand pin connection .with the container 1 to securely lock it engaged with` thev container to prevent the chalk therein from escaping and yet which permits the container to be filled when necessary..

so i

The reel 2O iscarriedby a shaft 21 rev i olubly Vmounted in a frame 22, saidy shaft being provided atone end with` a crank handle 23 to facilitate winding of the line on the reel. .Y e f The trame 22 is provided at its lowerend with a band 24 equipped at its lower edgev with a bayonet slot 25y designed to interlockingly engage with a pin 26 which projects laterallyfrom the top`2` as isshown clearly in Fig.y 1.

Int-he use ofV this device when it isdei siredto use it for a chalk line the plumb bob 15 is removed trom theskirt 11 by disengaging the lpins 16 thereof from the bayonet slots 12 and the parts will then be in ythe position shown in Fig. 3. The,V line 10 is drawn'out through the chalk yreceptacle or container land through the wiping de` vice 5a which leaves, just sufficient chalk on the line to makethe necessary mark. After it has been used the reel 2O is turned by turning the handle-23 which winds up the line lOthereon, the chalk having beenwiped therefrom in its passage through the wiper 5.

The plumb bob 15 is then inserted inKV the skirt 11 and Secured and the device then used as a plumb bob by disengaging the reel frame 22 from the chalk container by disengaging slot 25 from-pin 26 as shown in Figs. l and 2. The Weight of the plumb bob then will drop down and cause the line to unwind from the reel 2O and it may be used in the usual manner. lVhen finished for use as a plumb bob the line is wound up on the reel 2O and the frame with the collar Q4 engaged together with the top 2 of the casing and the device thus remains in compact form ready for use when desired.

I claim l. In a device ot the cla-ss described, a chalk container closed at both ends, a chalk line passing through said ends and through the container, an excess chalk remover mounted at one end of said container and made in the form of a cylinder having balls disposed therein, said line passing through Y Said cylinder in contact with said balls whereby the excess chalk is wiped from the line during its passage through the wiper,

said ball container having apertures for the discharge of chalk collected from the line. 7 A chalk container having a removable cover at one end und a depending skirt at the other, a plumb bob having a pin and slot connection With said skirt to detachably hold it engaged therewith, a reel carrying frame having a band at its lower end adapt ed to lit over the upper end of the chalk container, said band and container having interlocking means to detachably secure them together, and a chalk line secured at one end to said reel and passing through said chalk container and being provided beyond the bottom thereof with means to prevent the uf'ithdrawal oi the line through the container in an upward direction and adapted to permit it to be drawn downwardly in the opposite direction. l

ln testimony that I claim the 'foregoing as my own, I have hereto affixed my signature.
