Specification of Letters Pateint.y iaiggntggd Aug- 22, 1922 Application filed November 21, 1916. Serial No. 132,5/53.

(GRANTED UNDER THE PROVISIONS 6F THE ACT GF MARCH. 3, 1921, 41 STAT. L., y1313.)

To all 'whom t may concern:

Be it known that I, JOHN HAssnLBnRGER, a citizen of the Unitedy States, residing at East Hampton, in the county of Suffolk and State of New York, have invented certain new and useful Improvements in Painting Machines, of which the following is a specification.

rlhis invention relates to painting machines. y f

An important object of the invention is to provide in a machine of the above mentioned character a means whereby the paint may be evenly lvapplied to the surface of the object upon which the device as a whole iS designed to be operated.

A further object of the invention is to provide in a device of the above mentioned character a means whereby the greatest area of surface may be coated with the least pos-- sible amount of paint but at the same time supplying a suicient thickness of paint to materially preserve the object designed to be coated with the paint.

A further object' of the invention is to provide a device of the above mentioned character which 4is simple .in construction, inexpensive to manufacture, strong, durable, and reliable in operation.

Other objects and advantages of the in- Vvention will be apparent from the following description.

1n the accompanying drawings forming a part of this specification and inl which like numerals are employed to designate like parts throughout the same,

Figure -1 is a longitudinal vertical sectional view taken through the machine embodying` my invention, l

Figure 2 is a transverse vertical sectional view of the same takenon line-22 of Fig. 1, and n Figure 3 is a horizontal sectional view taken on the line 3-3 of Figure 1.

Fig. 1 is a detail of the rocking means for the crank shaft.

ln the drawings wherein for the purpose of illustration is shown a preferred form of my inventionthe numeral 5 indicates a receptacle provided with a top 7, a bottom 15 and ends 8 and 9.v rlhe receptacle 5 is divided into compartments 16-16 by means of vertically disposed walls 18. The compartments 16 are adapted to receive therein a quantity of paint as indicated in Figures 1 and 2.

16 with a plurality of openings indicated by the numerals 17. r1`hese openings are adapted to be opened and closedeby means of valves 18 vcarried by vertically disposed rods 19 movable in guides 19 carried by the side walls of the compartment '16. Journaled in the side walls of these compara ments adjacent their upper ends are crank shafts 2O which are operatively connected with the rods 19 by links 20.2 Connected with the upper ends of the crank shafts 2O are forwardly extending,operating rods 21. ln order to actuate the rods-21 there is provided a finger engaging member 22 having its upper end pivotally supported in a bearing 23 and its lower end engaged by and urged outwardly by a leaf spring 24 attached to the wall 9. This member 22 is formed with a 'horizontally disposed L- shaped extension 22 which 'is pivotally connected with the rods 21 as at 241.

From the disclosure thus far given it follows that upon pressin the member 22 inwardly toward the wal 9 the L-'shaped extension 22 moving .upwardly in an arc of a circle will move the rods 21 longitudinally to rock the crankshafts 2O which in turn lift the valves 18 from the openings 17 to permit paint from the compartments 16 to discharge through the openings 17. Within the lower portion of the frame 6 which supo ports' the receptacle 5 there 'is provided a plurality of horizontally disposed bearing supports 10, 11 and 12. Between the bearing supports 11 there is journaled apair of paint receiving rolls indicated by the numerals 28 which are adapted to be fed with paint carried within the receptacle 5 by means of angular disposed troughs or conduits indicated by the numerals 27 underlying the opening 17 and overlying the rolls 28. These rolls are adapted to be driven by means of sprocket chains 34C having engagement with the sprockets 85 .carrying horizontally disposed shafts journaled within the lower portion of the frame 6 as shown l The bottom 15 ofthe receptacle i is provided within each of the compartments in Figure 3. These shafts are provided with a plurality ofv rotating brushes 8.8, the facev of the endmost brushes being adapted to contact with horizontally [disposed wipers or brushes 311 secured to the frame 6 and extending longitudinally throughout the length of the same as clearly shown in F 1gure 3. These brushes are adapted to be driven or rotated by means of sprocket chains 34 having' engagement with the sprockets 35a carried by each of the horizontally disposed shafts provided with brushes hereinbefore mentioned and also having engagement with sprockets 35a carried by hori- Zontally disposed rotating shafts journaled within the frame 6 substantially intermediate the brushes 33, the last named shafts being provided with a plurality of driving wheels 32 adapted to travel'over the surface of the object to which the paint is desired to be applied. As illustrated in Figs. 2 and 3 one'set of brushes 33 is in vertical alinement with the paint receiving rolls 28 and the intermediate brush of this set is directlybelow these rolls 28 and serve asa paint applying brush.

Journaled in the bearing supports ll and disposed between the rolls 28 and the paint applying brush is a relatively large paintr receiving roll 30 'to which the paint from connected with the paint applying brush.

A lid 36 provided with a suitable locking key 37. is hingedly connected to the'receptacle 5 and serves as a means to permit paint to be poured into the receptacle. This lid 36 together with the locking means is'clearly shown in Figure l. A handle 25 is carried by the forward end of the ,casing 5 whereby i the machine is moved back and forth over the surface to be painted or coated.

` As shown in Figs. l and 2 the rolls 28 are slightly inclined in opposite directions and are formed with spiral longitudinally eX- tending grooves or channels 28a. ln this connection it will be stated that the rolls 28 are inclined justV enough to allovv'the paint to run through the grooves 28EL and thereby supply paint to the entire surface of the roll 30. Due to this slight inclination of the rolls 28 and the rotation of the samethe centrifugal force will prevent any of the paint from being discharged from the ends of these rolls.

In'the operation of my machine the same is pulled back and forth over the surface to be painted or coated by means of the handle 25 and the paint being supplied to the intermediate or paint applying brush 33 will be eventually applied to the surface. rlhe continued back and 4forth 'movement of the machine will cause the endbrushes 33 to spread and evenly rubthe paint into the surface.

The sets Aof brushes 33l disposed upon op- Having thus fully described the invention what is claimed is: v

l. A painting machine including a Wheel supported casing, a plurality of painting receiving compartments carried thereby and having ypaint discharge openings therein,
