The present invention relates to striping instruments and is especially applicable to instruments for striping panels or work of a. similar character in which a pattern or guide is employed. 1

A'nob'je'ct of the invention is to provide aninstrument for painting a stripe of umform width;

"Another object of the invention is to provide an instrumentfor painting stripes so constructed and arranged that the point or nozzle thereof may be adjusted in various positions. 4

Another object of the inventlon is to provide a striping instrument having a" pivoted nozzle provided with aguide member.

Another object offth'e invention to providea striping instrument comprising a resetvoir, a nozzle and means'intermediate the reservoir and the nozzle for metering a'fluid from-thereservoir through the nozzle at a rate commensurate with the' rate' of movementbf tlie instrument over the surface to be striped. f

A further object drum invention is to pro- 'vide a striping instrument having a handle and a reservoir supported thereby, the reservoir being adaptable for connection with the handle in different positions, that is, in axial alinement with the handle and normal to the axis thereof so that fluid may be fed by grav- I ity-from thereservoirto the handle regardless of the position inwhich the'instrument isheld.

A further object of the invention isto provideanozzle for a striping instrument having positioned therein a feeding means a'ctu ated by a rotatable member positioned; adj a cent the discharge end of the'nozzleL 7 a A still further object of the invention is to provide a striping instrument having a piv-- otednozzleprovided with means for regulating the How of a'fluid through the nozzle and means assooiatediwith the nozzle for actuating the regulatingmeans to controlthe flow at a rate proportional to the rate of movement of theinstrument.

"Further objects of the invention will appear in the 'following'description taken in 1928. Serial No. 272,384.

' instrument embodying my invention,

Figure2 is a longitudinal sectional view of the lnstrument,

Figure 3 is a detail view illustrating the handle,

Figure 4 is an end view of the handle,

' Figure 5 is aperspective View of a washer for positioning the pump gears,

Figure 6 is a plan view of the washer showing the gears positioned therein, and V Figure 7 is an enlarged sectional View taken substantially on line 77 of Fig. 2.

' Referring to the drawings for more specific details of the invention 10 represents a handle, one end of which has a diametral slot 11 and extendingfrom the slot 11 is a second diametral slot 12 of less width than the first mentioned slot,the object of which will hereinafter appear. The other end of the handle is provided with an axial bore 13 and a radial bore 14 and positioned in the handle parallel to the slots 11 and 12 is a bore 15 connected by a radial bore 16 to the axial bore 13, the

' the end ofthe handle as indicated at 17.

Threaded in the axial bore 13 at the end of the handle 10 is a reservoir 18 provided with a cap 19 having a ven't20 and the radial bore 14 has positioned thereina plug 21 which Y may be removed and replaced by the reser voir 18 in which case the plug 21 is threaded in the end of the handle. Thus, the reservoir may be positioned either in axial alinement with the handle or normal thereto in order to freely feed by gravity any fluid that may be contained therein through the handle regard less of the position in which the instrument is held, that is, at any position between horizontal and vertical.

Pivoted, in the slot 11 is a body 22. As

shown, the body is. provided with a reduced I end portion 23. having a transverse bore 24 and an annular channel 25. The reduced end portion 23 fits snugly in the slot 11 and the bore 24 registers with a diametral bore 26 in the handle .for the'reception of'a screw 27,

the screw beingprovided withasuitable washer 28. This structure provides means whereby the body may be adjusted at any angle rela' tive to the handle and tightly secured in position, the small diametral slot 12 in the handle permitting sufiicient contraction of the slot 11 to provide a tight joint,

The body 22 has a reduced end portion or nozzle 29 located centrally with respect thereto and"forming in connection therewith shoulder or annular face' 30. The nozzle is axially bored as indicated at 31 to communicate with passages 32 and 33 extending from the face inwardly. Also extending from the face 30 inwardly are passages 34 and 35 connected by a passage 36 to the annular channel 25 and the annular channel 25 communicates with the bore 15 in the handle through a radial bore or channel 37.

Positioned on the annular face 30 is a pin 38 adapted to prevent rotation of a washer 39 in which is positioned a gear pump. As shown, the washer 39 is provided with overlapping bores 40, 41 and 42, the central bore 41 being substantially twice the size of the bores 40 and 42. The washer 39 lies flush against the annular face 30 and has positioned in the bores 40, 41 and 42 intermes ling gears 43, 44 and 45. These gears form in connecw tion with the bores 40, 41 and 42 in the washa conical shaped sleeve is slipped over the sleeve 49 and bears upon the washer 39 to encase the gears. The sleeve 50 has a shoulder which is engaged by a flange 52 formed on a sleeve or cap 53 threaded on the nozzle 22. The sleeve 50 is further provided with a ball race 54 in which is positioned a plurality of ball bearings 55. A guide roller 56 which has a press fit on the sleeve 49 bears upon the balls 55. This guide roller is provided with a radial flange 57, the periphery of which is milled as indicated at 58, the objectof which will hereinafter appear, and positioned on the end of the reduced portion 29 is a conical shaped tip 59 which abuts the end of the sleeve 49 and provides a finish for the end of the nozzle.

In operation, assuming that liquid paint has been placed in the reservoir 18 and that the reservoir is positioned either in the end of the handle or normal to the axis thereof and that the body and nozzle are adjusted at anangle tothe axis of the handle by means of its pivotal connection, the instrumentis then ready for use.

At any adjusted position of the body and nozzle to the handle, liquid paint will flow by gravity from the reservoir l8'through the bore 13, the passages 16, 15 and 37, through the annular passage 25 and thence through the channel 36, the passages 34 and.

35 to the passages 46, 47 and 48 formed by the bores 40, 41 and 42 in the Washer 39 and the peripheries of the gears 43, 44 and 45 mounted in the bores. At this point the paint is received by the gear pump and as the instrument is moved over the surface to be striped the knurled or milled periphery of the flange 57 on the guide 56, engages a straight edge or pattern, as the case may be, and rotates the guide to drive through the sleeve connection the gear. 44 which meshes with and drives the gears 43 and 45, hence, as the gears are set in motion paint is pumped from the, passages 34 and 35 and delivered through the channels 46, 47 and 48 to the passages 32 and 33 from which it is ejected through the bore 31 of the nozzle in a con-@- stant flow of a uniform, predetermined quantity.

Although this invention has been described in connection with certain specific embodiments, the principles involved are susceptible of numerous other applications that will" readily occur to persons skilled in the art.

The invention is, therefore, to be limited-only as indicated by the scope of the appendedclaims.
