CHALK-LINE AND REEL.

SPECIFICATION forming part of Letters Patent No. 433,956, dated August 12, 1890.

Application filed February 25, 1890. Serial No. 341,717. (No model.) I

To all whom it may concern.-

Be it known. that I, MARTIN NELSON, a citizen of the United States of America, and a resident of the city of Quincy, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Chalk-Lines and Reels Therefor, of which the following is a full, clear, and exact description.

The chalk-line reel of this invention, and which is more especially designed for stone workers or cutters, in substance, is composed of a cylindrical and closed casing or shell adapted to contain. powdered chalk or other suitable material, and having a packed throat or passage leading from its inner to its outer side, a skeleton wheel located within and having its axle hung in bearings of the opposite side walls and at one end portion projected through and beyond the corresponding side wall of the casing, and a line held on and passing from said wheel through said throat of the casing, all so that the wheel, by the projected portion of its axle, can be rotated from the outside of the casing and the line can pass into and out of the casing as it is reeled and unreeled by said wheel, and otherwise, in combination with an arm which is in two parts, at one end of each hinged together, and has one part at its end opposite to its hinged end held on said projected portion of the wheel-axle, so that the axle may freely turn in it, and has the other part at its end opposite to its hinged end adapted when it is folded upon the part held on the wheelaxle, as stated, to be engaged with said axle, and thereby the arm, as a whole, madea handle to the axle for convenience in turning it, and when opened out from the part held on the wheel-axle, as stated, to be engaged with the casing, and thereby made secure against movement in either direction of the turning or rotation of the wheel.

Further than the above, the invention consists in the combination, with the casing, of abrush whichis detachably attached to and entered into it, and also in the combination, with the line, of a flexible or pliable pad, which is confined,but is free to move lengthwise on it, all substantially as and for the several purposes hereinafter specified.

In the drawings forming part of this specification, Figure 1 is an exterior view of the casing of the reel and showing the chalk-line as extending therefrom and having the [lexible pad and a hook for engaging it, as desired.

Fig. 2 is a section, line 2 2, Fig. 1. Fig. 3 is a vertical section, line 3 3, Fig. 1. Fig. 4 is an elevation of a block of stone, showing the line caught by its hook thereon and the working of its pad in connection, with the stone and line, as will hereinafter appear. Fig. 5 is a broken view of a block of stone and showing a straight-edge, the working-edge of which has been previously prepared with chalk placed on the upper face thereof, allas will hereinafter appear.

In the drawings, A A are the opposite sides, and A is the edge or rim, and severally made of any suitable materialforinstance, sheetbrass or other 1netaland together constituting a closed cylindrical shell or casing of the reel of this invention.

B and B are the opposite parallel sides, and B are the parallel rods, having open spaces between and joining and held on said sides and severally arranged at equal distances from the axis of the axle B joining said sides,

and as a whole making a wheel that is disposed within and'lies between and by its said axle is hung to turn in bearings of the sides of the casing.

The wheel-axle at one end portion B projects through and to and beyond the outer face of the side A of the casing. The wheelsides B B have openings 13 through them, and the several parallel rods 13 together make a barrel or central portion for the winding and unwinding of achalk-line C, which is secured by tying (not shown) or otherwise suitably to one of said rods.

D is a throat or passage through the rim A of the casing and at one side of the reeling-wheel, and the chalk-line as it is wound and unwound from said wheel, running over a guide-roller D of the casing, passes through this threat.

E is a thickness of leather or other suitable packing material applied to and held on the rim of the casing by a plate E and screws E and lying over and across the throat or passage D of the casing, and this leather has a continuation D of said passage, and of suitable diameter relative to the chalk-line to serve as a packing thereto and the throat D of the casing, and thus prevent the escape of the powdered chalk (shown at F, Fig. 3) or other suitable material with which the casing is charged for suitably preparing or coating the chalk-line therewith as the line is reeled and unreeeled in use.

G G is an arm in two parts, and having one part G at one end by a screw-nut a applied sto the projected portion of the axle of the reeling-wheel, held on and loosely surrounding said axle, so that the axle may freely turn in it, and at the other end hinged, as at Z), to the other part G which has a square-sided opening (I to engage, when it is folded over and upon the part G, as shown in dotted lines, Fig. 3, the square sides of the nut a of said axle, and has also an armf, swiveled on its outer end, and when the part G? is opened out from the part G to lie against the rim of the casing. WVith the part G of the arm G G engaged with the wheel-axle, as explained, the arm as a whole makes a handle to said axle for con venience in turning it, and through it the wheel to reel the lineonto the wheel, and with the arm f of the part G of the arm G G lying against the rim of the casing the arm is secured against turning with the wheel as it turns in reeling the line 01f of the wheel.

H is a brush held on a h cad-block H which is adapted to be screwed into and out of a screw-thread opening l'l through one side of the casing and inserted, as stated The brush projects into the powdered contents of the casing for being charged therewith, and thus adapted for the use for which this brush is providedto wit, for chalking with it the working-edge g of a straight-edge J, so that placing said edge on the face of a stone K, Fig. 5, desired to be finished with a smooth and even face, the projecting and irregular portions of said face will be marked by the chalk and so indicated as to insure their final removal by the stone-Worker and the securing of the desired smoothness and evenness of the face of the stone.

L is a hook of right-angular shape secured and hung on the outer end of the chalk-line C, and to be used for engaging the line, as, for illustration, Fig. 4, with the under side of a stone M, and thence running the line up one side N of the stone to and around the corner or edge 0, made by it and the top face P of the stone, and from this corner along the top face of the stone to be chalk-lined by holding and snapping the chalk-line, all as well known.

Q is a flexible and pliable pad, made of leather or other suitable material and having an ear-piece Q, by which it is'held on the chalkline, so as to be free to be moved there along. In the running of a chalk-line as just explained, and as illustrated, Fig. 2, this pad is to be placed about the corner or edge 0 of the stone for the chalk-line to run over it, and thus it serves as a guard to the line, and by preventing its contact with said corner or edge it obviates the possibility of its being out or otherwise injured thereby as the line is held and snapped, as well known.

Having thus described my invention,what I claim, and desireto secure by Letters Patent, is

l. A chalk-line reel composed of a closed cylindrical casing or shell having a guideroller and a packed throat for the passage of the line, in combination with a skeleton reeling-wheel located within and having its axle arranged to turn in suitable bearings of the sides, and at one end projected through and beyond the casing, an arm in two parts, one G at one end, held on the projected axle of the reeling-wheel, and in which said axle is free to turn, and at the other end hinged to the other part G and which has an opening (I to engage the wheel-axle, and a swiveled arm f to engage the rim of the casing, substantially as described, for the purposes specified.

2. A chalk-line reel composed of a closed cylindrical casing or shell having a guideroller and a packed throat for the passage of the line, in combination with a skeleton reeling-wheel located within and having its axle arranged to turn in suitable bearings of the sides, and at one end projected through and beyond the casing, means held on said projected axle for turning it, and a brush held on a head or holder adapted to be screwed into and out of a screw-threaded opening of the casing, and thereby to enter the brush into and to remove it from the casing, substantially as described, for the purposes specified.

3. A chalk-line reel composed of a closed cylindrical casing or shell having a guideroller and a packed throat for the passage of the line,in combination with a skeleton reeling-wheel located within and having its axle arranged to turn in suitable bearings of the sides, and at one end projected through and beyond the casing, means held on said projected axle for turning it, and a flexible and pliable pad held on and movable lengthwise of the chalk-line, substantially as described, for the purposes specified.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

MARTIN NELSON.
