Patented Feb. 16, 1937 UNITED STATES PATENT GFFICE 14 Claims.

This application is a continuation in part of my prior copending application Serial No. 506,800, filed January 5, 1931.

The present invention relates to improvements in stripe painting devices and has. for an object to provide an improved device for painting lines or stripes on automobiles, signs, furniture, etc.

The invention is intended to replace the present method of painting lines, stripings and the like on automobiles, furniture, signs, interior decorations and the like, such as stripings on cupboard doors,` cabinets, etc. 'Ihe present method requires the labor of highly skilled mechanics who must use a ne brush with painstaking care, which necessarily makes the work slow and expensive.

The improved device consists of an automatic, self-feeding painting device, which may or may not be mounted upon a specially designed adjustable carriage with an adjustable holder for guiding the paint brush on a given line.

Another object of the invention is to pro.- vide an improved painting device or brush which will be automatic in action in the manner of feeding the paint to the brush tip whereby to insure a free flow of the paint and the uniform making of the objects.

A further object of the invention is to provide an improved painting or striping device useful in connection with a carriage which will be guided by a molding, or which may carry a gage or guiding device for the purpose of compelling the striping to follow a straight line.

A still further object of the invention is to provide an improved painting or striping device in which an automatic vibrator may be provided in connection with the paint feeding tongue which operates through the paint discharge tip for the purpose of facilitating the continuous and uniform feed of the paint to the object surface.

A still further object of the invention is to provide a reservoir in connection with the device so arranged and mounted that it may always occupy a substantially vertical position the better to induce the iiow by gravity of the liquid paint therefrom.

The invention is also concerned with certain auxiliary devices, such as guiding tracks for the carriage, a tiltable table support for the brush or pencil, and nozzles or tips of various sizes and shapes for the production of fine or heavy lines in single or multiple groups.

With the foregoing and other objects in view, the invention will be more particularly described hereinafter and more fully pointed out in the appended claims.

Fig. 15 is a longitudinal section taken through a further alternative embodiment of the invention and illustrating in detail the manner of assembling the paint feeding stem.

Now it will be understood that the device is susceptible of many mechanical forms, some few only of which are illustrated in the drawings. Referring more particularly to the drawings, I2 designates a tip having an outlet orice for directing the paint on to the surface to be striped. Through the orice of the tip I2 a paint feeding tongue I3 is adapted to project. This tongue I3 Will normally be projected by resilient spring action outwardly of the tip l2, but will be shifted inwardly of the tip I2 when such tip engages the surface to be painted as shown in Fig. 2.

Now the tip I2 may be made in various shapes and sizes with one or more orifices of various dimensions and for this purpose the tips are preferably interchangeable. To this end the tips may be provided with internally threaded sockets I for screwing on and off externally threaded nipples I5 upon a tubular nipple holder l5. The holder I6 is provided with a nut portion I1 for enabling it to be screwed into and out of a tubular reservoir barrel I8. The nipple holder I6 carries therewithin an automatic valve device similar to the valve insides of the inner tube of an automobile tire. The stem i9, which carries the tongue I3 extends up through the holder I6 and the valve insides. When the automatic valve is open, as it is shown in Fig. 2, the paint is adapted to feed along the stem I5 down to the tongue I3 and out on to the surface with which the tip I2 is in contact.

Although the valve insides is well known in construction and operation it will be briefly described as follows:

A hollow threaded cap 26 is screwed into the lower end of the holder i6 and carries the valve seat 2I which fits snugly within the holder, this valve seat 2I being usually provided with an outer part of rubber. Both the parts 2B and 2l have a loose t about the stem I9. as to move with the stem I9 is a valve plunger 22 having a valve facing to seat against the seat 2|, the valve being urged against the seat 2I by a coiled spring 23 which is wound about the stem I5 and abuts at one end against the plunger 22 and at its other end against a collar 24 loosely fitting about the stem I9 and abutting against a shoulder 25 within the holder I6. In Fig. 2 the valve 22 is shown as being open or raised from its seat 2I owing to the fact that the tongue i3 has been pushed inwardly by contact with the surface to be painted.

Although an automatic vibrator is not essential, when such device is to be used, the stem I9 is continued upwardly and engages in a socket 26 formed in an armature 21 of an electrical vibrating or other vibrator device. The coil of the vibrator is indicated at 28 and the make and break contact at 29. The lead in wires 3l) may carry a plug for connection to any electricalV outlet socket. When the current is turned on, the energized core 3l of the electromagnet 28 will attract the armature 21, thus breaking the circuit at the contact 29 which will destroy the attraction, thus allowing the contact to spring back and make the circuit again at 29. This make and break action continues rapidly in the vibration of the stem I9 and the tongue I3, and inducing the free flow of the paint to the painted surface through the nozzle I2.

The vibrating device is shown as contained within a holder 32 forming a unitary device which may be screwed into and out of or otherwise removably connected with a base 33. Through a coupling device 34, the base 33 may be carried upon a metal or other hollow tube 35 which will surround and protect the stem I9. The tube 35 may be supported in any appropriate manner in axial alignment with the barrel I8. ,Where a supply reservoir, such as the reservoir 36 is to be used in conjunction with the painting device, it will be appropriate to join the tube 35 and the reservoir connection in the same coupling member. To this end a T-GOll- Aiiixed so I pling is shown into the lower branch of which the barrel I8 is screwed and to the upper branch of which the tube 35 is connected as by the use of a coupling sleeve 3B. Within this coupling member may be mounted a tubular rubber or other sleeve or gasket 39 which will have a tendency to prevent any of the paint from flowing upwardly into the tube 35. The horizontal branch of the T-coupling 31 is connected to a needle valve casing Within the casing 40 is a needle valve 4I operable by a head 42 for the purpose of controlling the outflow from the reservoir 35 to the brush. The reservoir 36 preferably has a swivel mounting about the needle valve casing ill). This swivel support is had by means of a sleeve 43 carrying the reservoir 36 and fitting rotatably about a reduced portion or neck M of the needle valve casing 4I). The sleeve 43 abuts at one end against a shoulder 45 formed by the enlarged portion of the needle valve casing 43 and a friction washer 46 is preferably interposed between these parts. At its opposite end the sleeve 43 is confined by a nut threaded upon the reduced neck 44 and having a friction washer 48 interposed between the nut l1 and the sleeve 133. By loosening the nut 41, the sleeve 53 and reservoir 36 may be adjusted angularly to any desired position about the needle valve casing lli). Upon tightening the nut 41, suincient frictional pressure may be brought to bear to retain the reservoir 36 in the adjusted position. An annular channel 4B of the sleeve i3 circumscribes a circumferential group of ports 4Q in the reduced neck M. The needle valve 4I may be carried by a screw sleeve 50 which will permit the valve assembly to be removed for purposes of cleaning.

The reservoir 36 is preferably removably carried by the swivel sleeve 43 and carries a downwardly projecting threaded socket 5I to receive the threaded nipple 52 of said sleeve. The reservoir 36 may be of any appropriate construction, one form of which is shown in Fig. 2, as comprising an external receptacle with an internal tube 53 therein. This internal central tube 53 is important when the device is used in the manner illustrated in Fig. 10. The reservoir 36 may be filled with iiuid paint by removing the cover 54 provided with the breathing opening 55. Outflow of the paint is under the control of a valve 56 which is threaded through the side of the reservoir and through an orifice in the side wall of the tube 53. By opening thi'.I valve 56 the paint will be permitted to flow through the oriiice down to the needle valve 4I.

A supply of the paint may always be kept in the tube 53 to ow out under control of the needle valve 4I. An extremely ne adjustment may be had by this needle valve GI. Into the upper end of the tube 53 is screwed a coupling 51 which projects up through the cap 54 and receives a small cap 5S serving to close the upper end thereof when used in the manner shown in Fig. 2. When used in the manner illustrated in Fig. 10, this small cap 58 may be removed to permit the coupling 51 to be screwed directly into the socket 59 projecting downwardly from the vibrator base 33.

Whereas in Fig. 2 the vibrator 32 is shown to be in line with the tip` and the vibrating tongue, and the reservoir 36 is shown to one side of these parts, in Fig. l0 the reservoir 36 and vibrator 32 are illustrated as in line with one another and with the tip and vibrating tongue. In this instance, the vibrating stem I9 extends up through drawing the tip and T9.

the tube 53 of the reservoir and up into the vibrator which is coupled to the reservoir in the manner just related. In Fig. 10 the needle valve 4I is dispensed with and a closure cap 60 is tted over the horizontal branch of the T-coupling 31. The device in Fig. 10 may be used in substantially the same manner as a pencil, being guided across the surface to be painted or striped by the hand of the operator. Of course, the vibrating device 32 might be omitted from Fig. 10, and the vibration of the tongue I3 may be obtained by maintaining a steady pressure of the tip I2 against the surface to be painted and I2 along this surface. This action causes tongue I3, which is depressed and under tension, to skip along over the innitesimal bumps and hollows which will be found even on the smoothest piece of glass.

Another embodiment of the invention, illustrated in Fig. 5, shows the reservoir 38 dispensed with, a supply of the liquid paint being maintained in a barrel 62 which forms the pencil or enclosing casing of the device. This enclosing casing 62 is in effect a large barrel, or rather an enlargement of a barrel, such as the barrel I8 shown in Fig. 2. The valve assembly, tip and tongue arrangement shown in Fig. 2 and already described is carried by this barrel 62. The barrel 62 may receive a supply of liquid paint through the filling neck 63 which is normally closed by the cap 64. The barrel 62 may or may not carry the vibrator 32.

In Figs. 6 and 7 I show a modified form of the tip I2 and the tongue arrangement. In this instance the tongue is provided with two forks I3 adapted to operate through two orifices in the tip I2. This is for the purpose of making two parallel lines or markings. It will be quite apparent that the tongues may be made in any multiple number of forks with orifices to correspond in the tip. The tongues may also be made of various widths for making heavy and light lines.

Referring more particularly to Fig. 4, the device described in connection with Fig. 2 is shown as for use in making vertical markings upon a perpendicular surface. Here the value of the swivel connection for the reservoir 36 is apparent. Whereas the pencil or brush device is obliged to assume a substantially horizontal position for the purpose of making these perpendicular markings, nevertheless, the reservoir 38 may be shifted to an upright position whereby the flow of the paint under the force of gravity may be maintained just as in the case where horizontal surfaces are being marked or striped.

Referring more particularly to Figs. 1, 2 and 3, the brush or pencil is also adapted for mounting in connection with a carriage including a pair of relatively movable trucks 65 and 66 supported for rolling movement upon wheels 61 and 68. These wheels are slidably mounted on axles 69 The trucks and their respective wheels are secured to the axles 69 and 'I0 by the use of set screws 'II and 12. Upon the trucks 65 and 86 is an adjustable bed 'I3 slotted, as indicated at 14, to receive set screws l5 which take into the trucks. By loosening the set screws and the set screws II and l2, the trucks 65 and 56 may be adjusted axially along the axles 59 and I8 and the bed T3 may be adjusted relatively to the trucks 65 and BS.

A plate I6 is mounted upon the bed I3 and above such plate 'I6 is a tiltable platform 'Il having screws 'I8 in any appropriate number threaded therethrough and taking against the plate 16. Through both plate 'I6 and the platform 'I'I and also through the bed 'I3 extends a pivot bolt 'I9 (Fig. 2) having a head 80 at its lower end for engaging beneath the bed 'I3 and enabling the tiltable platform I'I to be rotated on the bed. Riveted or otherwise secured to the tiltable platform TI is a plate 8l having a bracket 82 rising therefrom and swivelly connected with an upstanding curved arm 83 on a holding sleeve 84 adapted to embrace the barrel I8 of the pencil or brush. A set .screw 85 carried by the sleeve 84 clamps against the barrel I8. By unloosening the screw 85, the barrel I8 and the entire pencil or brush may be rotated in the sleeve 84 for purpose of adjustment. The lower part of the arm 83 swivelly carries a rod 8S which extends through the bracket S2 and is surrounded by a coil spring 8l, the tension of which may be adjusted by a nut 88 threaded upon the outer end of the rod 86. As shown in Fig 3, a wing nut 89 may be employed to make fast the swivel connection between the bracket 82 and the arm 83.

As shown in Figs. 2 and 3, a gage plate or guide 90 may be mounted upon the axles 69 and 1I). Bearings 9! which slip over the axles carry the plate 98, and set screws 92 are provided for xing the bearings upon the axles in the appropriate position. As shown in Fig. 2, this gage plate or guide 98 may operate against a side surface of the surface to be painted or striped and thus cause the carriage and the pencil to move in a rectilinear path which is essential in making an accurate straight line or in a true curved line, or the carriage Ymight be guided by a track such as shown in Figs. 8 and 9, in which a track strip 93 is shown being connected by pieces 94 to rubber or other vacuum cups 95. These vacuum cups 95 are pressed tightly against the surface to be painted or striped and the wheels of the trucks are rolled along against the guide strip or track 93 thus insuring the correct path for the pencil tip.

In the use of the device, a simple form of the implement will consist merely of the tip, vibrating tongue, and valve device with an appropriate source of paint supply. This device may be moved over the surface to be painted guided by the hand of the operator. During this movement the tip will'be vibrated toward and from the surface thus giving the necessary vibration to the tongue to open the valve 22 and permit the free ow of the paint, or the vibrating device may be included, as shown in Fig. 5. Where both the vibrating device and the reservoir are desirable, either the form shown in Fig. 2 or that shown in Fig. l0 may be employed.

The device may also be mounted upon the carriage with or without the gage 99 or the guide strip 93. Where there is a molding to be followed such as is found upon automobiles, the trucks 65 and 66 of the carriage may be grouped closely together so that the wheels 6l' and 68 will engage opposite sides of such molding. Here the molding itself is the guiding surface or track. It will be obvious that the pencil may be placed between the trucks 65 and 66 or the trucks may be grouped together and the pencil disposed at one or the other side of the trucks. In encountering irregular or sloping surfaces, the tiltable platform il may be caused to assume any angular position by adjusting the set screws 18. Also this platform 'I'I may be rotated to a desired position about the central bolt 79. A nut I9 may be used to tighten bolt 19. The coil spring 81 will add the requisite pressure of the tip against the surface to be painted. In operating the device, the heel of the hand may be placed upon the carriage while the pencil is taken between the thumb and fingers as in the act of writing with a lead pencil. This will facilitate the movement of the carriage and the proper operation of the device.

From the construction it will be apparent that the tip may be readily removed and interchanged for tips of other sizes and forms. The tips may be readily removed for cleaning as may other parts of the device. The paint may be supplied to the barrel or reservoir of the device by the use of a pump or syringe.

In the structural embodiment shown in Fig. 12, the tubular reservoir 35 is provided with a lateral rectangular enlargement providing a reservoir 36 whereby the capacity of the reservoir is increased. The reservoir has an extension 5i that is disposed in swivel connection with the axially aligned barrel section i8 which in turn is connected at its outer extremity, as by threading, with a holder i6' which receives in detachable engagement the threaded tip l2 provided with an axial paint feed bore and having therein a valve seat which is adapted to be closed by a valve 24 disposed on the stem i9 which extends axially through the tip, the holder, and through the barrel lli'. The inner extremity of the stem I9 lies well within the reservoir 36 and is provided at its end with an eye which receives in sliding engagement the second stem i9 having its outer end provided with an eye J8 that is slidably engaged over the stem section i9', which eye acts as an abutment for a coiled expansion spring 91 surrounding the stem section i5 between the eye 93 and a xed enlargement sii carrie-d by the stem section i9' and within the barrel I8'.

The reservoir 35' is further provided with a tubular extension 99 axially aligned with the extension 5l at the opposite end of the reservoir, which extension $9 receives in threaded engagement a ller plug l provided on its inner face with an inwardly extending tubular socket lill that is adapted for loose sliding engagement over the extremity of the stem section l". The socket IBI is internally threaded to receive the threaded stem lil of a tensioning screw H33 threaded in the socket and which is adapted to be adjusted so that its inner end bears against the tip of the stem section lil within the socket and forces the same inwardly of the reservoir against expansion of the spring Sl which, in turn, acting against the shoulder 9E imparts a tension to the stem section I9'. This arrangement of elements allows an extremely rlne extension adjustment of the projecting stem i9' at the tip l2'.

It is to be noted furthermore that the swivel connection of the reservoir with the barrel i8 permits of a vertical disposition of the reservoir section 36 irrespective of vertical or horizontal 'use or" the striper tip l2. The barrel section i8 has slidably disposed thereover a longitudinally extending sleeve Ell@ that is adapted to be fixed in a desired position by manipulation of a set screw |65 and which sleeve carries two parallel spaced laterally extending threaded stems lli, each of which has threaded thereover a pair of retaining nuts lill which are adapted to receive therebetween the shank H38 of a work guide element. The shank Hi8 may comprise a substantially flat bar apertured for engagement over the stems l E16 and which is provided at its end toward the tip of the striper with a stem m9 which is longitudinally slidable in one end of a tubular casing llt, with the extremity of the stem |09 bearing against a compression spring lll seated within the casing. The casing at its outer extremity carries a work engageable guide Wheel Il?. Obviously, by proper adjustment of shank m8 by the adjusting nuts lill, the guide element may beproperly disposed in parallel spaced relation to the work engaging tip l2 of the striper.

Figure 13 illustrates an adaptation of the striper as shown in Fig. 12 wherein an electric vibrator is employed, the details whereof are substantially similar to the vibrator shown in Figs. 1, 2 and 10.

In the embodiment shown in Figure 13, like reference Acharacters have been employed to designate like parts as in Fig. l2. In this embodiment of the invention the casing S2 of the vibrator unit is attached directly to the reservoir extension 3S". The vibrator comprises an electrical coil 23 having a magnetic core 3 i adapted to cooperate with the make and break contact 2S to cause oscillation of a striker arm 2l that projects from the casing 32 and which is provided with a down turned portion 2l which is received within the reservoir 35 through a slot provided for the purpose to permit sufficient oscillation of the striker arm in operation of the vibrator. At its lower end the striker arm 2l is forked for straddling in loose engagement over the stem section i9.

It will be apparent that as the vibrator is operated the rapidly oscillating striker arm 2l through its loose forked engagement over the stem section i9 will alternately strike the stem section from opposite sides and thus impart thereto a vibration which is in turn transmitted to the stem section I9' at the tip of the striper. Thus, the vibration is secured without imparting any movement to the stem axially of the tip i2. This is an important feature of the invention in that the necessary vibration is imparted to the stem to assure a constant feed or the paint material and yet at the same time there is no actual reciprocation of the stem within the tip l2 during this vibration. In the art of vibrators employed prior to the advent of this invention there has been in every instance a reciprocatory movement of the stem or tongue axially of the tip and this results in a rapid striking of the work with a consequent tendency to disalignment. In the present invention the stem I9 is dep-ressible within the tip upon work Contact and thereafter does not move axially of the tip until the striper is released Jfrom contact with the work.

In the special embodiment shown in Fig. 15 there is an axial alignment of tip l2', holder I6', and paint reservoir barrel l i3. This structure as to stem arrangement and general disposition of parts is practically identical with the form shown in Fig. l2, except that the reservoir extension 36" of that iigure is eliminated in this form. Like parts have been indicated by like reference characters so that no further description for these elements is necessary,

In the structural embodiment as shown in Fig. l5, the work guide element may be mounted directly on the barrel H3 through the instrumentality of sleeve lid, adjustable along the barrel by a set screw l I5, and which sleeve carries a projecting threaded stem lili which receives the shank lll of the guide element, adjustment being secured by proper manipulation of the adjusting nuts H8. The shank H1 is longitudinally slotted as at H9 to provide for a proper sliding engagement thereof With respect to a retaining stem formed on the barrel as the sleeve is adjusted over the barrel.
