SPECIFICATION forming part of Letters Patent No. 504,833, dated September 12, 1893. Application filed May 10, 1893. Serial No.4'73.64.5. (No model.)
To @ZZ whom it may concern:
Beit known that I, WrLLrAM CHARLES GEB- HARDT, a citizen of the United States, residing at Luling, in the county of Caldwell and State of Texas, have invented new and useful Improvements in Paintinghiachines, of which the following is a specification.
The object of my invention is to provide an automatic device for painting large surfaces which may be operated by an unskilled person, and it consists of a reservoir for the paint suitably connected with a paint brush to which is given a sweep similar to that of an expert painter by suitable mechanism actuated by the advance of the machine containing said reservoir and brush. The number of reservoirs and of brushes may be multiplied to suit convenience and the size of the machine. Where the paint does not iiow readily to the brush or brushes, I provide an air pump connected with the reservoir to provide an internal pressure to force the paint through the connections. In the accompanying drawings I have shown this pump as driven by the advance of the painting machine, but it may also be operated by hand. lVhen desired the painting machine may be preceded by a sweeping device removably attached thereto and followed by a smoothing or surfacing device also removably attached to the rear of the painting machine proper. IVhere of large size, the painting machine is provided with a canopy and automatic fan to protect the workman when driving the machine, a very necessary adjunct when painting roofs or other exposed surfaces in hot and sunny weather. Means are also provided for lifting and turning the painting machine.
In the accompanying drawings which illustrate my invention: Figures 1,2, and 3 are plan views of the forward central and rear parts of my machine, with the canopy removed, showing in Fig. l the sweeper attachment with the forward end ofthe painting machine proper; in Fig. 2 the central part ofthe painting machine proper and in Fig. 3 the rear end of the latter, and the surfaceing attachment. Figs. 4, 5, and 6 are side elevations of the same and Figs. 7, S, 9, IO, ll. and
5o l2 are views of various details.
A, Figs. l and ai., is the frame of the sweeping attachment secured to the frame, A", of the painting machine proper in any suitable way.
B is the dust box pivoted to the forward end of the frame A so as to have a vertical swing.
b is a rope or chain secured to the dust box tray B at b', passing through eyes b2, b2, in the sweeper frame braces a a2 and extending back within reach of the operative who fastens it to the hook b3 on the frame A', Fig. 5, in order tov hold the tray in position when sweeping, and releases it to lower and empty the box at the proper moment, as when the sweeper projects over the housetop which is being painted.
4 is the projecting dust box lid or fender.
C is the roller dust brush of any suitable construction, carried in the pendent brackets C', in which its shaft c is vertically adjustable in any well known way. In the drawings the shaft c is shown adjustable by means of a series of apertures c in the brackets O', which latter are securely braced to the sweeper frame A.
c2 is the belt wheel keyed to the dust brush shaft c over which passes the driving belt C2 connecting with a pulley C3 on the forward wheel G of the painting machine proper.
D is a splasher board fastened to a cross brace a on the frame A and located behind the dust brush C to protect it from paintv thrown by the brushes of the painting ma chine proper. The splasherboard D is braced to the cross piece a by the small chain d whichallows the board to yield to obstructions, as when passing over the seams on a tinned roof.
The construction of the painting machine proper is as follows:
E E', Figs. 1 and A, are the forward paint brushes located across the front of the painting machine proper. Each brush consists of one or more parallel series of bristles (see Fig. '7) e e', secured in a well-known wav to the brush back E2. The ends e2 e2 of vthe brush back engage with slotted guides E3 on each side of the machine, suspended by brackets E4 secured to and adjustable vertically in IOO the frame A in any well known way, in order to raise or lower the brushes in respect to the surface to be painted. In the drawingsI have shown the brushes and guides vertically adjusted by means of bolts passing through the frame A and apertures e1 i n the brackets E4, but I do not limit myself to the same. Agage bar E5 at each end of the brush E hooks over the bolt heads e5 on the corresponding ends of the brush E to hold them parallel and at suitable distance apart. The paint brushes E E are reciprocated by means of the rods E6 connecting the brush E to the cranks ff of the crank shaft F which turns in the fixed bearings F braced to the main frame A', (see Figs. l, 2, 4, 5,) and to which the front wheels G of the painting machine are keyed. The front and rear ends e3 of the slotted guides E3 are turned up so as to lift and tilt the brushes at the end of each sweep before again bringing them in contact with the surface to be painted, and thus alternately presents each side of the brushes in the operation of painting, reproducing mechanically all the movements of anexpert painter.
E7 E8 (Figs. 2 and 5) are the center paint brushes reciprocatingin the slotted guides E9 and connected by rods E10 with the cranksf2f2 of the crank shaft F2, turning in the iixed bearings F3 braced to the main frame A and to which the rear wheels G of the painting machine are keyed; and E11, E12 (Figs. 3 and 6) are the rear paint brushes reciprocating in the slotted guides E13 and connected to the cranks fsf3 of the crank shaft F2 by the rods E11; the slotted guides E9 and E13 for each pair of' brushes EVT Es and E11 E12, as shown in the drawings, are formed in one piece suspended by the brackets E15 E16 from the main frame A and adjustable vertically by bolts and apertures e4 in every respect similar to the adjustment of the forward brushes; but it is evident that the guides may be formed in two pieces independently adjustable if desired.
e6 and eT are the gage rods between each set of brushes ET ES and E11 E12. It is thus seen that the rear crank shaft F2 actuates two sets of paint brushes in every respect identical in their construction, connections and operation with the forward brushes; but that I may dispense with all of these and use but one reciprocating paint brush, its guide and suitable connections to which movement is imparted by the wheel of the painting machine proper to reciprocate the brush without in anywise departing from the spirit of my invention and irrespective of the manner in which the paint is supplied to the brush.
The mechanism for feeding paint to the paint brushes is constructed as follows:
H, Figs. 2 and 5, is the paint mixing cylinder which rests in the saddles h h firmly secured to the cross braces a2 c3 of the frame A (Fig. 2). Itis provided with handles 7L h by which it may be lifted on and off the saddles h 7i to which it is fastened venient and well known way.
H2 is a funnel for lling the cylinder and has a screw threaded stopper h2 to securely close the same, but any other Well known device may be used.
H3 is the mixer stirrer of well known construction having keyed on the exterior end of its shaft h2 a driving wheel H1 over which passes the belt H5 driven by the pulley H6 keyed to the rear crank shaft F2 of the machine.
H7, Figs. 2 and 5, is the paint cylinder below the level of the mixer cylinder and suspended at both ends in the stirrups h2 hs in any conhanging from the frame A and wedged firmly in place by the removable inverted saddles H8 which t over it and under the frame A.
717 Ware handles for removing the cylinder H7, which is also provided with a stirrer H1 having its driving wheel mounted on the opposite end of the stirrer shaft and connected by belt and pulley to the forward crank shaft F of the machine on that side (not shown.)
I I are gages on the cylinders H H2 to determine the quantity of paint in each of them. In Figs. 2 and 5 I haveshown the cylinder H7 formed in two sections bolted together at H10 in order that it may be taken apart for cleaning the interior; but all of the cylinders in the machine, as well as the mixer and paint cylinders H H7 may be constructed in any well known way in order to render the interior of the same accessible for any purpose.
.I (Fig. 5) is a detachable pipe connecting the bottom of the mixer cylinder H with the interior of the paint cylinder H7, through which the paint flows from the former to the latter.
K, K, (Figs. l and 4) are flexible tubes which convey the paint from the paint cylinder H7 to the sprinkler K, Fig. 7, attached to the front paint brush E below the brush back E2 between the sets of bristles e e. The sprinkler K consists of a tube having anumber of small apertures lc through which the paint iiows onto the bristles.
K2, Fig. 7, is a valve for cuttingoff the supply of paint to the brush upon which it is mounted and consists of the hollow sleeve k with which the supply pipes K and the sprinkler K connect; and the valve spindle 7a2 having the ports k3 which register with the pipe and sprinkler connections, when it is open; lo* is the handle for closing the valve. .K5 are iiexible pipes conducting the paint toa similar valve K2 on the forward paint brush E.
KGK7 are the tubes communicating with the central brushes E7 E2, Fig. 5, and K8 K1 (Fig. 6) the tubes connecting the rear paint brushes E11 E12 withthe paint cylinder H1, shown only in part in the drawings; if required the paint may be cut olf from the rear brushes E11 E12 which can then be used as smoothing brushes in place of the smoothing attachment described hereinafter.
IOO
IIO
In order to force the paint through the pipe l connections I supply compressed air to the mixer cylinder II by means of the air pump L, Figs. 2, 5, and 9, mounted upon the painting machine, in which L is the pump cylinder, L2 the piston rod having a detachable pivot connection at Z2 with the driving rod L3 pivoted to the driving wheel Z3 keyed on the end of the crank shaft F2 of the rear wheels G.
L2 L4 are perforated caps through which the air enters the cylinder L through the valves L5.
L5 is the compressed air chamber having the two valves LT. A coiled spring Z5 abutting against the cross head of the inverted U-shaped valve guide ZT around the teat Z8 and against the conical head of the valve L7 normally holds the latter down closing the port Z2. A cross piece Z2 having a central aperture forming a collar around the conical head of the valve, engages with the guide ZT on either side and slides up and down with the rise and fall of the valve.
Z10 are rods which are screwed down upon the cross piece Z9 in order to permanently close the port Z4 when desired.
In Fig. I2 I have shown a modification of the locking attachment to the valve L2 in which the rods Z10 pass through apertures Z12 on the cross piece ZD and are provided with upper and lower shoulders Z13 Z14 between which the cross piece rises and falls with the play of the valve. To lock the valve LT down over the port Z4 closing it, the rods Z10 are screwed down until the upper shoulders Z13 bear against the cross piece Z9 the latter holding down the valve.
I do not limit myself to the particular con struction of the valves shown, as any valve will answer my purpose which is adapted to be locked in position when required. The valves L5 are of similar construction except that the rod Z10 is attached to the valve itself and projects through the perforated caps L2, through which it plays freely with the movement of the valve which is permanently closed by screwing down the nut ZU.
LS is a communicating pipe between the compressed air reservoir Ll? and the mixer cylinder H,opening near the top of the latter and out of the path of the stirrer H3.
L2 is a pipe connecting the cylinders II and I-IT through which the airpressure may be admitted to the latter by opening the cock L1.
\Vhere the surface is ribbed as on a tinned roof I provide an additional attachment consisting of the brushes M, M, Figs. 2, 5, and S, facing each other in order to paint each side of the rim or rib, and respectively secured to the two prongs of the forked hanger M which is laterally adjustable along the cross piece M2 by a bolt and bolt holes m to adjust the pairs of brushes to the distance between the ribs. A sprinkler M3 (Fig. S) projects in front of each pair of brushes which may be two or more in number where it is firmly held by one of the braces m2 which rigidly fasten the brushes to the hanger M.
M4 is a valve to open and close the sprinkler and M5 the tube connecting it with the cylinder H7.
The brushes M9 M12 are independently attachable to the cross piece M2, as shown in the lower set of brushes in Fig. 2, in order to adjust them to the width ot' the rib. The cross piece M2 is rocked in bearings Mi6 by means of the hand lever M7 in order to raise and lower the brushes and sprinkler when desired.
M8 is a rack in which the lever M7 is locked when the brushes are raised.
N, Figs. 2 and IO, is a sprinkler rocking on journalsnin bearings in the arms N N pendent from the frame A in front of the central set of paint brushes E7 ES. It consists of the perforated tube N having a valve spindle N2 with ports similar to those of the paint brush supply valves K2 to ope-n and close the sprinkler.
N2 is the valve handle.
N4 is the paint supply tube communicating with the paint cylinder H7.
N5 is an inclosing rim to hold the drippings when the sprinkler is rocked up.
N6 is the lever for rocking the sprinkler NT a catch to hold the lever.
The surfacing device which is rigidly attached to the rear of thepainting machine proper consists of the frame A3 (Figs. 3 and 6) provided with front and rear bearings O O for the journals O2 03 of the rotating drums O4 O5 over which passes an endless canvas belt I? to which is firmly riveted a series of transverse brushes P having the construction shown in Fig. 1l,in which each brush is surrounded with a rimmed pan p to catch the drippings from the brush when the latter is inverted and thus keep the beltPclean. Endless chains Q Q communicate motion to the belt P by means of the sprocket wheels Q on the rear crank shaft F2 and the sprocket wheels Q2 on the drum journal O2 to which they are respectively keyed.
The drums O2 O5 may be provided with cocks 0LL o5 whereby they can be used for the storage o'r' paint and turpentine.
R Fig. 5, is the handle by which the operaf tive directs the movements of the entire machine as he walks on one side of it and pushes it along.
In order to turn the machine in the least possible space, I raise it entirely off the surface and pivot it on its center by means of the following device: S is a bar having a tripod foot s suspended by its piston head s in the piston S' open at its upper end and firmly secured to the cross brace 0,4 placed centrally across the machine frame. A coiled spring 2 surrounding the bar S within the piston abuts between the piston head s and the bottom of the piston7 and normally holds the foot clear of the surface. In order to depress the and foot and raise the machine, I pivot the lever IOO IIO
S4 to the cross brace a4, the head of the lever bearing against a plunger S5 in the open end of the piston. It follows that by raising the lever arm S6 the plunger S5 is forced down and with it the piston head s compressing the spring S3 and raising the entire machine off the surface.
ST is a toothed sector for locking the lever arm in place while turning the machine.
T Figs. 5 and 6, is the canopy frame over which the canopy is stretched.
'U, Fig. 5, is a fan mounted in suitable bearings and over which passes the endless belt U2 from the wheel U3 keyed to the shaft U* which turns in suitable bearingsin the frame T. Another belt U5 passing over the pulley U6 keyed to the same shaft and over the pulley U7 on the forward crank shaft F of the machine communicates motion to the fan.
The front and rear wheels G, G of the painting machine are laterally adjustable upon their respective crank shafts F F2, Figs. l, 2, and 3, by means of the pins and bolt holes g on the crank shafts, the object being to set the wheels to the width of the ribs on a tinned roof, which thus serve as guides or Ways to direct the machine.
The operation of my machine is as follows: The mixer cylinder H being filled with the proper ingredients and all opened, the machine is pushed along by the operative. The revolution of the wheels turns the cranks and drives the brushes, while the paint is forced through the various connections by the air pressure produced by the air pump. At the end of each lap the machine is pivoted upon its foot, the sweepings from the dust pan having been discharged as described. When it is desired to clean the pipe connection I shut olf the valves L7 and L5 of the air pump L, and having lled the cylinder L with turpentine or any suitable liquid, I detach the brush connections from the cylinder HT and connect them with one or the other of the cylinder cocks a: y. I then detach the piston rod L2 from its driving rod L3 and operate the piston rod by hand, forcing the contained liquid through the pipes and valves to clean them out. I thus provide a compact and useful painting machine of simple construction, easily run by a single unskilled person, and capable of performing in a given time the work of a large number of skilled painters, thus effecting a great saving and economy of labor.
I do not limit myself to the detailed construction of my device, which may be greatly varied without departing from the spirit of my invention, but
