CHRISTIAN, OF DETROIT, MICHIGAN, ASSIGNOR TO PACKARD MOTOR CAR COMPANY, OF DETROIT, MICHIGAN, A CORPORATION OF MICHIGAN STRIPING INSTRUMENT Application lied November 19, 1928. Serial Np. 320,234.

This invention relates to striping instru- Ifnents and more particularly to nozzles there- In striping, ruling and analogous arts, when an instrument ortool is drawn or moved from left to right or vice versa, generally angular movements are imparted to the instrument due to twisting of the operators wrist in effecting the stroke. These angular movements are in a plane in the direction of movezo nozzle ment of the instrument and transversely with respect thereto. They are directly responsible for unsatisfactory results because they cause uncertain engagement of the point or nozzle of the instrument with the surface operated upon and this results in wavy uneven lines or stripes. It is the aim of the present invention to overcome these objections.

An ob'ect of the invention is to provide a or a striping instrument having means providing for positive en agement of the nozzle with the surface to e operated upon.

Another object of the invention is to provide a nozzle for a striping instrument having means permitting angular movement of the instrument without disengaging the nozzle from the surface to be operated upon.

Another object of theinvention is to provide a nozzle for a striping instrument having means adapted to press the nozzle in engagement with a surface to be operated upon, an means permitting rocking or angular movement of the nozzle without disengaging the surface.Y

Yet another object of the invention is to provide a nozzle having means for supporting the discharge end thereof in spaced relation to the surface to be operated upon.

A further object of the invention is to provide a nozzle for a stripin instrument avin means for supporting t e discharge end o the nozzle in proper relation to the surface to be operated upon and for scoring the surface to restrict the spread of liquid discharged through the nozzle.

A further object of the invention is to provide a nozzle having a two-point contact or engagement with the surface to be opere0 ated upon, the engaging means being arvunderstood that other ranged to permit rocking or an ular movement without disengagement o the nozzle and defining the spread of the liquid discharged through the nozzle.

Other objects of the invention will appear from the following description taken in connection with the drawings, which forms 'a part of this specification, and in which:

Fig. lis a side elevation of a striping instrument embodying the invention, parts of the instrument being broken away and parts in section Fig. 2 is a rear elevation of the instrument, the container, which is also the handle, being broken away;

Filg. 3 is an enlarged side elevation of the nozz e;

Fig. 7 is a side elevation of the modified form illustrated in Fig. 6;

Fig. 8 is an end elevation of yet another modification, and

Fig. 9 is a side elevation of the modification illustrated in Fig. 8.

Referring to the drawings for more specific details of the invention, 10 represents the body of the instrument which may be any preferred form adaptable for supporting a pump mechanism. As shown, the body of the instrument has positioned therein 'a pump 1l, the intake 12 of which is connected y a passage 13 to a container 14 threaded in the body portion. The container is also the handle of the instrument.

The pump is operated by a roller 15 suitably connected by a shaft 16 to one of the gears or the pump and the roller is provided with a circumferential groove 17 adaptable for engagement with a bead 18 formed or secured on a surface 19, though it is, of course,

ide means may be employed. The pump gids an outlet 20 connected by a suitable passage 21 to a hollow -shaft 22 extending from one 'side of the body 10 and the shaft has positioned thereon for gagement with the surface to be operatedv upon. Thus any angularmovement'of the instrument in a plane inthe direction of movement of the instrument will not disengage the nozzle from the surface.

The discharge end 26 of the nozzle is an angle to the body thereof and mounted for reciprocation in the discharge end is a floating or spring pressed sleeve 27. As shown, the discharge end of the nozzle has an axial bore 28 at an ,angle to the bore or pas- -sage 24 in the body of the'nozzle, and the sleeve 27 is fitted for reciprocation in the axial bore 28, movement of the sleeve being restricted within certain limits by a pin 29` in the end 26 engaging a slot 30 in the Wall of the sleeve.

The sleeve 27 is normally pressed downwardly or outwardly by a flat spring 31 secured on the body of the nozzle and the bore 32 in the sleeve registers with the bore or passage 24-in the body of the nozzle through an elongated port 33 or other-suitable means of depressing the sleeve 27 may be used.

The discharge end of the nozzle is cut Y obliquely to its axis as shown at 34 and the sleeve 27 is likewise cut obliquely to its axis as at 35. The oblique end of the sleeve 27 is oppositely disposed with respect to the. oblique end of the nozzle, so that the spaces between the end of the nozzle and the end of the fioating or reciprocatory sleeve is substantially that of an isosceles triangle, the altitude of which is, of course, dependent upon the degree of the angle or cut of the oblique edges of the nozzle and the sleeve.

Any angular movement transversely with respect to the movement of the instrument will be taken `care of by the reciprocatory sleeve 27 and the spring 31 which retains the sleeve in engagement with the surface to be operated upon. The spring 31 is sufficiently sensitive to cause the sleeve 27 to actpromptly upon the slightest angular movement of the instrument transversely with respect to the direction of movement thereof.

The discharge end of the nozzle and the reciprocatory sleeve 27 provide suitable means for engaging the'surface to be operated upon and to support the nozzle in proper relation thereto, so that when operating the instrument, the liquid discharged from the nozzle may -be deposited and' smoothed out by" the oblique edges 34 and 35 in the form of a stripe, the cross sectional contour of which is substantially in accordance with the space between the edges 34 and 35. It is to be observed that the oblique edges 34 and 35 pron vide a two-point en agement for the.V nozzle with the surface to te operated upon.` This serves not only to support the discharge end of the nozzle but to define the spread of the liquid. Defining and' restricting the spread of the liquid is accomplished by the edges 34 and 35 biting into, scratching or scoring the surface as the instrument is manipulated, and by so defining the spread of the liquid therey is Vproduced a stripe of uniform width throughout its length.

A modified form of the nozzle is shown in Fig. 5. `lnfthis modification, the discharge end 26 has positioned therein a reciprocatory sleeve 36, the movementof which is restricted by the pin 29 in the wall of the nozzle en-v gaging the slot 3() in the wall of the sleeve. The sleeve 36 is normally urged outwardly by a coil spring 37 positioned between the top of the sleeve and the top Wall of the nozzle, and the spring 37 is sufficiently sensitive to maintain the sleeve 36 in engagement with the surface 'to be striped. The sleeve 36 has a bore 32 and this bore communicates with the passage 24 through the elongated slot 33. The discharge end of the nozzle and the reciprocatory sleeve are alike in construction to that shown in Figs. 1 to 4.

A further modificationV is shown in Figs.

6 and 7 in which the nozzlediflersy only in` the discharge end thereof. As shown, the oblique ends 34 and'35 are accentuated or made more acute, so that the engaging points are sharp and well defined' and hence will scratch, bite or score more deeply into the surface to be o erated upon. This modification further differs in that the oblique cuts terminate abruptly in a cut substantially normal to the axis of the discharge end 26 of the nozzle and the reciprocatory sleeve 27 positioned therein. This gives a different 4character to the stri e in that it smooths the stripe out with a at top, whereas in the form shown in Figs. l to 5 the stripe is more in the formof an isosceles triangle as hereinbefore explained.

ss y

A still further modification is shown in Figs. 8 and 9 in which the nozzle also differs only in the matter of the discharge end. In this modification, both the nozzle and the reciprocatory sleeve have an arcuate cut which provides a space intermediate their respective engaging points substantially semi-elliptic. A. cut of this character, of course, smooths out the stripe with a curved or semi-elliptic top, whereas inI the other modifications the stripes as applied are, in cross section, substantially an isosceles triangle and a frustrum respectively.
