I (Cl. '15-140-) Claims.

This invention relates to improvements in striping tools.

The main objects of this invention are:

First, to provide a hand striping tool of improved construction greatly facilitating the acators arm in manipulating the hand tool, with results which are greatly .improved from the standpoint of ease, uniformity and evenness of deposition of the stripe, and ease and speed of operation.

Third, to provide a hand striping device for the application of striping material to angled objects, which enables the unfailing production of uniformly satisfactory striping jobs by relatively unskilled operators.

Fourth, to provide a hand-striping tool of the character described having associated therewith an improved striping or paint applying roller which in cooperation with the features-above noted furthers the uniformitysof application of stripes to angled objects.

Fifth, to provide a striping device for manual use having a pigment applying roller of novel construction.

Sixth, to provide a striping device having'gauge means and a pigment applying roller incorporated therein in a novel manner to increase the ease and speed of producing a satisfactorily uniform job.

Seventh, to provide a striping device of the above character having a=pigment containera'ssociated therewith in -a novel manner to-prevent undesired changes in the consistency or quality of the pigment dueto the heat of thecperators handemployed in manipulating the 'de v1ce.

Objects relating to details and economies of the invention will appear frorn'the description to follow. The invention is defined and pointed out in the claims.

A structure embodying the features of the invention is illustrated in the accompanying drawing, wherein:

Fig. 1 is a view in side elevation partially broken awayand in section to illustrate details of construction and arrangement of thestriping device ,of the invention.

a 'Fig. 2 is an enlarged fragmentary viewin section on line 22 of Fig. 3, further illustrating structural features .of the device.

Fig. 3 is an enlarged View ofthe device along the line designated 33 in Fig. .2, with parts of the device removed and with the Work operated on indicated by dotted lines.

fFig. 4 is a greatly enlarged view illustrating in section a portion of the striping roller and work toillustrate the constr-uction-of the .paint orpigment applying roller.

Fig. 5 is an enlarged fragmentary view still further illustrating the construction ofthe applying roller of the .present device and the manner in which it coacts with the work in insuring a uniformly copious distribution of paint or pigment thereon.

This invention relates generally to improvements in striping devices such as are employed in the application of paint stripes to angled structures such as frames, shelves and the like, in which operation it is'nece'ssary that a continuous uniform movement. of the striping device he performed 'to the end that the application of the pigment Willbe uniform and free from spots or-areastowhichpaint or pigment has been applied undesirably lightly or heavily. For this operation, stripers have heretofore been employed in whicha striping roller is "mounted at one end thereof to rotate about an axis extending transversely of the length of the device, the device being manipulated somewhat in the manner of a paintbrush. This type of device may be used with quite satisfactory results when plain surfaces are being treated. However, in applying a stripe running around a corner or around an angle, for example, such as the refrigerator shelf which I have illustratedin dotte'd lines -in Fig. 3, difiiculty has arisen heretofore because of the practical impossibility in using such stripingdevices for the operator to round the corner of the article in a singleuninterrupted stroke of constantsp'eed. The reason for this is that the arm extends longitudinally'of the device and it is ex-' ceedingly diflicult to guide the same while swinging'the ar n about the shoulder for the required uniform movement, without which deposition of the paint or pigment in local excessively heavy or excessively light :areas inevitably results. It is a primary object of myinvention to provide a device in which'these defects or objectionable features are not present, and; one which is manipw,

lated by a simple, wrist pivoting to round corners, although various other details thereof likewise contribute to the aforesaid desired result of a uniform continuous stripe for angled objects.

Referring to the drawing, the reference numeral l in general indicates the implement of the invention illustrated. This comprises an elongated cylindrical tubular body 2 adapted to be grasped by the user in the manner indicated in dotted lines in Fig. 1. This tubular body 2 is provided with a partition 3 separating the body into a paint or coating container portion or reservoir 4 from the grip portion 5. This arrangement serves to prevent the heat of the users hand from affecting the consistency of the paint or coating material in the reservoir 4. This factor is of very substantial importance since the paint or coating material ordinarily employed in striping is subject to changing conditions as a result of even such heating as'results from the hand of the operator grasping the implement where the reservoir extends into the grip portion as is quite common practice.

The reservoir 4 is provided with a filling dome 40 closed by the filler plug 6 and provided with the vent l which may be adjusted to enable efiicient filling and also to enable the flow of the liquid pigment or coating material. The reservoir is provided with a detachable end closure plate 8 detachably secured by screws 42. The reservoir is also provided with a lateral discharge mouth or slot 9, the plate 3 constituting one side wall of this slot.

The edge walls ID of the slot are extended into parallel ways 43 which slidably receive the gauging gate or slide l l which is recessed at 44 on one side to receive the spring 45, taking up lost motion between the gate and its ways,

The striping roller 12 is journaled on the stub shaft or pin l3 so that it is supported within the slot or mouth 9 to project into the reservoir and to project from the slot. The body member has a relatively short laterally projecting nose 46 in which the slot is formed.

It will be noted that the roller I2 is retained on its stub shaft i3 by means of the end plate; also that the said adjusting or gauging member I I is engaged with a lug 41 on the nut l4 so that the gauging member is retained by the removable end wall.

The adjusting screw is rotatably mounted in the top wall of the reservoir to engage this-nut member M, the screw being provided with a knurled finger piece l6.

The gauging member is of general forked shape, its arms or forks being extended into the feed or discharge spaces between the periphery of the roller l2 and the edges of the discharge slot, as shown in Fig. 3, there being segmentally curved portions 48 coacting with opposed portions of the roller, as shown in Fig. 3.

The striping roller 12 has a concaved serrated periphery or face E8, the serrations being preferably of V-shape and extending entirely across the concaved face, as shown in Figs. 2, 4 and 5. This I find to be a matter of very substantial importance in that it enables the effective picking up of a substantial quantity of the pigment and the effective depositing thereof along the line of striping which in this case illustrated extends longitudinally of a groove 19 in a frame 2!). With the face of the roller thus conformed, the pigment or coating material is effectively picked up from the reservoir and carried to the point of discharge where it is effectively discharged. The

l g r gauging member can be adjusted to effectively gauge the amount.

The individual teeth of the roller perform a very effective delivery and distributing action, preventing the localized areas of insufficient or excessive pigment or coating.

As the thinnin liquid commonly employed is highly volatile, it is a feature of great advantage to be able to thoroughly clean the device after it has been idle or when the use is discontinued. The removable end plate affords access to the movable and adjustable parts so that they can be effectively cleaned and the reservoir drained and cleaned.

To further insure accuracy and uniformity of deposition of the pigment, I provide the device of my invention with a gauge instrumentality including a work engaging finger 2| secured to a crosshead 22 which is slidably adjustable on the body of the instrument and maintained from rotation thereon by engagement with a longitudinally extending key 23 on the top of said body. A threaded screw 24 rotatable in said crosshead and threadedly engaging an enlargement or boss 25 on the front end of the tool body is employed for effecting accurate longitudinal adjustment of the positioning finger, being provided with an enlarged knurled portion 26 to facilitate this. In finally adjusted position of the gauge finger 2|, the crosshead 22 may be clamped by means of a knurled screw 2'! to lock the parts in desired position and enable large numbers of pieces to be striped without danger of dislocating the guide finger arrangement.

It will be apparent from the foregoing that I have provided a hand striping device which greatly facilitates the production of uniform striping jobs on irregularly shaped objects. As stated, it is exceedingly difficult to operate on angled objects with presently employed stripers and produce uniform results at the angles thereof, and a structure incorporating a striping roller journaled parallel to the length of the device overcomes this difiiculty. The effectiveness of the result is furthered by the use of a striping roller of improved design which insures the presence of adequate striping material and simultaneously performs a local distributing action thereon as it is deposited. The mechanical difiiculty of operating the device is further diminished by the adjustable guide feature, and the difiiculty which has heretofore arisen because of the volatile nature of the striping liquid, and the fact that it has in hitherto known stripers been subjected to the heat of the operators hand, is overcome by the arrangement of the pigment supply reservoir in my device.

I have illustrated and described my improvements in an embodiment which is very practical.- I have not attempted to illustrate or describe other embodiments or adaptations as it is believed this disclosure will enable those skilled in the art to embody or adapt my improvements as may be desired.
