Patented Apr. 5, 1932 UNITED STATES PATENT OFFICE JOHN M. CHRISTMAN, 013 DETROIT, MICHIGAN, ASSIGNOR TO PACKARD MOTOR CARI COMPANY, OF DETROIT, MICHIGAN, A CORPORATIONOF MICHIGAN I srmrme INSTRUMENT,

Application filed October 9, 1928. Serial No. 311,305.

This invention relates to striping instruments and is particularly adapted for use in applying cement.

An object of the invention is to provide an instrument for applying a uniform stripe.

Another object of the invention is to provide an instrument having means for feeding liquid cement or similar liquid material from a Container through a nozzle in a uni- 10 form flow in direct proportion to the rate of movement of the instrument; I i Another object of the invention is to provide an instrument for applying liquid having a roller arranged tosupport the instru- 15 ment,'to coact with the surface upon which it is desired to apply the liquid and to operate a mechanism for automatically feeding liquid in direct proportion to the rate of movement of the instrument.

20 J A further object of the invention is to provide an instrument for applying liquid having a combined guide engaging member and nozzle.

A further object of the invention is to pro- 25 vide an instrument for applying liquid having a member arranged for coaction with a guiding bead or straight edge and provided with an arcuate face permittin an angular movement of the instrumentwithout disengaging the guide engaging member.

A still furtherobiect of the invention is to provide an instrument for applying cement whichis highlv efficient in operation yet of "marked simplicity as a whole and in respect to each of its component parts, so that its manufacture is economicallv facilitated both as to parts and their assembly.

Other obiects of the invention willappear from the following description taken in con- .nection with the drawings, which form a part of this specification, and in which:

Fig. 1 is a side elevation ofan instrument embodying the invention v Fig. 2 is afront elevation with the handle removed;

Fig. 3 is a sectional view substantially on line 33 of Fig. 2; y I Fig. 4 is a sectional view on line 44 of 50 Fig. 1, and

Fig. 5 is a sectional view on line 55 of Fig.

Referring by numerals to the drawings, represents the body of the instrument which, as shown, is substantially rectangular in general contour. The body is provided with a transverse bore 11 in which is positioned for rotation a shaft 12. The shaft 12 has a shouldered portion 13 on which is secured a roller 14. This roller comprises a hub 15 having a flange 16 and a disk 17, preferably rubber, secured on the hubby a plate 18 held in position by anut 19 threaded on the shaft 12.

Mounted on the body portion 10 is a gear pump; ,As shown, the body portion supports .a'plate 20 having overlapping transverse bores 21 and 22 in which are positioned intermeshing gears 23 and 24, the gear 24 being, formed, keyed or otherwise secured to the shaft 12. Theplate 20 is covered by a plate 25and these plates are secured in position by a plurality of screws which extend through the'plates and are threaded into the body portion.

The'body portion has mounted thereon a container'26 which, as shown, comprises a hollow cylindrical member threaded into the body portion as indicated at 27 and provided upon-its free end with a .cap 28 in which is positioned a suitable vent 29. This container serves a twofold function in that it also provides a handle for the instrument. Leading from the lower end of the container is a passage 30 which extends through the body to the intake port 31 of the pump.

The plate 25 covering the plate 20 and the gears positioned therein, has a port 32 forming the outlet port of the pump and a passage 7 33 leading therefrom to a passage 34 positioned normal thereto in a nozzle 35 shown as formed integral with the plate 25.' The noz- .zle 35 has a curved or arcuate face 36 preferably coinciding substantially with the circumference of the roller 14 and arranged sub stantially centrally in the face 36is a groove 37 adaptable for engagement with a bead as shown in Fig. 1, for guiding theinstrument. or the side 38 of the nozzle may be engaged with a straight edge for this purpose. Ex-

- tending from the passage 34 to the rear end of the nozzle is aplura-lity of discharge orifices 39 equally spaced with respect to each other and substantially in alinement crosswise of the line of travel of the instrument.

The orifices 39 are of suitable size to deliver liquid in finestreams and are so spaced with respect to each other that the liquid so discharged will, when applied to the Work,

spread and unite to form a layer of substantial width and uniform thickness. This'is particularly desirable whereit is the aimto cement one member to another and avoid the use of an excessive quantity of cement and also where it is desired to attain a uniformity in the application of liquids.

. The nozzleis an important featurerofthe invention. Because of the curved or arcuate face ,36,'the instrument may he rocked slight- .ly as itis-moved over the surface without liability of disengaging the nozzle from the .guide with which itcoacts orwithout materially changing the relation of the discharge orifices to the work. Thus slight movements of an operators wrist while manipulatingsthe instrument will not disengage the instrumentfrom the work'nor affect the discharge of liquid thereon.

The mode of operation is as followszCement is placed in the container 26 and the roller 14 revolved until the gearpump deliversthe cement to the nozzle whereupon the instrument is engaged with and moved along the work by engaging the groove 37 with a lbead'or-theside 38 with a straightedge.

VVithithe instrument in thisposition it is drawn forwardly in :the direction indicated bythe arrow, shownin Fig. 1, and as it is drawn over the surfacethe roller 14 revolves and operates the gear pump 'to withdraw :the cement or other liquid fromxthe con- 'tainer 26rthr0ugh 'theport 31 and deliver it through the port 32 and passages 33 and 34 to the nozzle :35 from which it is ejected through the orifices 39 at one end of the curved or arcuate face 36 in a uniform flow in direct proportion to the rateof movement of the instrument.

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

The invention is, therefore, to be limited only as indicated by the scope of the appended claims. 7
