SPECIFICATION forming part of Letters Patent No. 443,576, dated December 30, 1890.

Application filed October 8, 1883. Serial No. 287,570. (No model.)

To all whom it may concern.-

Be it known that I, Enos S. HAWKS, a citizen of the United States of America, residing at Oummington', in the county of Hampshire and State of Massachusetts, have invented certain new and useful Improvements in Painting-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings. and to letters and figures of reference marked thereon,which form a part of this specification.

This invention relates to painting-m achines designed to paint plain surfaces, such as the sides of houses; and it consists in the improved construction, herein after set forth and claimed.

In the accompanying drawings, Figure 1 is a front view of a painting-machine constructed in accordance with my invention. Fig. 2 is a rear view. Fig. 3 is avertical section taken through the line no a: of Fig. 1, partly broken away at the top. Fig. 4: is a front View of a portion of the operating mechanism, the parts being broken away. Fig. 5 is a detail perspective view. Fig. 6 is a front view of one of the intermittent gear-wheels. Fig. 7 is a front view of the bar upon which the wheel in Fig. 6 is mounted. Fig. 8 is a plan View of the intermittent wheel mounted abovethe wheel shown in Fig. 6. Fig. 9 is a sectional view of the brush-carriage, looking from the under side thereof. Fig. 10 is a detailplan view of the brush-carriage. Fig. 11 is a sectional view through the dotted line w w of Fig. 1, taken through the brush-carriage and adjacent parts. Fig. 12 is a sectional view through the dotted line y y of Fig. 1. Fig. 13 is a sectional view through the dotted line .2 z of Fig. 1.

The main frame of the machine has vertical posts A, Figs. 1, 2, 3, at, and 12, to which are secured, so as to be adjustable thereon, cross-beams A, to which are movably attached clamps aa, each having portions bent to embrace the beams, the free ends of said portions being adjacently arranged and perforated for the engagement of a bolt'a' to secure the clamp on the beam. Each clamp is extended at its rear to form a projection (F, the inner side of which may be roughened or padded to bear against the sides of the building at right angles and thus enable the v main frame to be rigidly clamped on the front of the building by devices now described.

Transversely through the rear extended portions of the upper andlower clamps passes a horizontal rod a Figs. 2 and 3, one end of which is shouldered to bear against the outer clamps 64 passes a screw-threaded crank-shaft a Figs. 1, 2, and 3, the end of which is adapted to abut against the front of the building, adjacent to the corners thereof, to steady and prevent the vibration of the main frame and insure the proper contact of.the brushes with the surface of the building.

At the intersection of the posts A and.

beams A clamps B B, Figs. 1, 2, 3, and at, are located, these clamps consisting of plates 1) and b, which are connected to each other rigidly by posts 19 riveted to the rear plates. Upon these posts, which are four in number, a disk b (shown in Fig. 3,) having corresponding perforations, is placed, and with the center of said disks a setescrew B engages, the plate I) being screw-threaded, so that said set-screw will engage therewith and the end thereof bear upon the movable disk 12 so as to hold the parts securely in position. It will be observed that the main frame can be ex tended laterally and vertically, so as to be placed upon buildings of different widthsand heights.

Each post A is provided on its inner and outer side with a vertical longitudinal groove A A transverse brush-carrying frame is composed of horizontal beams G O, which are secured imposition by means of vertical bars 0 playing in the inner and outer grooves, each pair of bars carrying adjacent to the upper and lower beams O 0 four rearwardly-extendinghorizontal bolts, in which the beam is seated, said beam being retained in posi- Lil tion by a back plate 0, which embraces the ends of the several bolts at each intersection. The upper and lower plates 0 at one side may be connected rigidly to the horizontal beams; but at the opposite side they are removably connected by means of screws 0 to admit of the parts being loosened and provide for a lateral adjustment of the clamping means proportionate with the movement of the post A of the main frame, when the width of thelatter is to be adjusted. The upper beam 0 is provided on its rear side with a rack-bar C, with which a wheel for operating the brushes engages, as will be hereinafter set forth. These beams C C are provided on their opposite horizontal faces with grooves o as seen in Fig. 3, in which the brush-carriage moves and is guided. One of the upper clamps c is provided with a bearing 0, Fig. 2, through which a spirally-grooved shaft 8 passes, the opposite end of said shaft being supported by a bracket secured near one end of the upper beam 0. From the upper portions of the outer bars extend brackets c", Fig. 1,which are internally screw-threaded, and through the same the vertical screw-threaded shafts D D pass, the front disks Z) of the upper clamps B B having brackets b and U, Figs. 1 and 2, secured thereto, these brackets having horizontal bent portions, which serve as bearings for vertical shafts, as shown, said shafts turning freely in said bearings.

D D, Figs. 1, 2, and 3,1'efer to screw-threaded shafts, which are mounted in bearings, so as to be maintained in a position parallel with the posts A A of. the main frame, the lower portion of these screw-threaded shafts being mounted in bearings attached to projecting arms (Z and d, which are rigidly attached to the posts A. The lower ends of these shafts have attached thereto beveled gear-wheels which engage with beveled wheels mounted 011 a horizontal shaft E, so that the brush-carrying frame will be raised or lowered when the screw-threaded shafts D are turned. The said shaft E is provided with a longitudinal groove c, and is supported in suitable bearings connected to the posts A. This shaft carries beveled pinions 1,2, 3, and 4, said beveled pinions being adapted to mesh in corresponding pinions (Z and f on the lower ends of theseveral shafts D D 0. The pinions 1 and 2 are loosely mounted on the shaft E and are thrown in connection with said shaft by clutches g and g,carried by suitable arms connected to a bar G. The arm carrying the clutch g is adjustably secured to the bar G, while the arm carryingthe clutch g is rigidly secured thereto. One end of the shaft E has secured thereto a crank arm or pulley for turning the same, and by this shaft the machine is operated.

The shaft E, in addition to carrying the pinions heretofore referred to, also carries a worm E, which has pivoted thereto a dog adapted to fold down to lie partially within The bars G, Fi s. 1 and 2, ma be made of .a single piece having an outwardly-bent portion, ora bent portion may be attached thereto, so as to allow the gear-wheels to lie above the same. The end of this bar is connected to a plate II by a-bolt which passes through a slot formed therein, and at its end it is pro vided with a spring which engages with a stud 71-, projecting from the plate Il, Figs. 1. and 4-. This bar G is thrown to the right and left by a lever 2', pivoted to the plate H, and connected by a link t" to the bar G, so that by moving said lever the clutches carried by said bar will be thrown either in or outof engagement with the pinions mounted on the grooved shaft E. The bar G also carries a dog I, adapted to engage an outward projection 92 formed on a gear-wheel N, to throw said bar automatically, the action of which will be hereinafter set forth. It will be observed that the bar G is attached movably to one of the posts, so that the post can be extended laterally.

The plate ll, Figs. 1, 2, i, and 7, is secured rigidly to the post A of the main frame, and also to the end of the lower cross-beam A thereof, and it is provided with an outwardlyprojecting stud it, against which bears a bar K, (shown in detail in Fig. 5,) and with this stud 7r a suitable bolt engages, which passes through the slot in the bar K. This bar K carries arms which engage with clutches 7L7 and 71 which slide upon the slotted shaft E when the armsare moved, so as to be thrown in or out of engagement with the pinions 3 and i upon said shaft. The opposite end of this bar K has a longitudinal slot 70 through which passes a bolt 7t, bearing in the screw upon which cam 0' is mounted, and said bolt 7; supports the other end of said bar. Up to this point of the description with reference to bar K, it. will be noted that the two bolts passing through the slots of said bar support it, but enable it to have a transverse hori zontal movement. The said bar K is provided on its rear face at eitherside of the slot 7& with upper and lower projections 7.; 70. A curved spring 0 parallel with the periphery of the cam, between the shoulders thereof, has one end secured to said periphery by being seated in a recess therefor in the face of said cam, while the free end of said spring is limited by a pin 0 projecting from the wheel 0. The parts being in the position shownin dotted and full lines, Fig. 1-, as the cam rcvolves in the direction of the arrow the spring will be compressed against the periphery of the cam between the shoulders thereof by the projection 70, since the bar K is held immovable bythe cam-shoulderbearing against one of the projections while the spring is pressed against the periphery by the-other projection. Now when the cam-shoulder in 7 contact with the projection k compresses it,

and reverses the movement of the bar K in the manner previously explained. The bar K is also provided with a V-shaped slot R in which a pin p attached to a member P, (of a lever to be described,) passes, so that the member will be operated when the bar is moved by the cam.

To one of the vertical posts A of the main frame, above the longitudinal slotted shaft E, is secured a bracket L, Figs. 1, 2, 4, and 12, which has a depending portion, to which is secured by means of a bolt Z a hollow knob Z, the lower portion of which knob is reduced in diameter so as to form a bearing upon which the intermittent gear-wheel M will turn. This knob is provided with an arm on, the end of which is provided with a pin adapted to engage with perforations formed adjacent to the periphery of the wheel M, and the opposite side of this arm is provided with an outwardly-proj ectin g pin m, which engages with a trip-bar R. By means of this hollow knob and securing-bolt Z the arm can be adjusted to enter different perforations, thereby giving, through the intervention of the trip-bar and other mechanism, the distance of the travel of the carriage carrying the brushes.

The gear-wheel M meshes with the worm E, located on the shaft E. The hollow knobl (see Fig. 12) has an interior shoulder against which a spiral springwhich encircles the bolt engages, so that said knob may be raised upon the bolt Z to adjust the arm m to engage the different perforations in the wheel. This spring also serves to hold the wheel M against the depending portion of the bracket L, to prevent the same slipping.

To the plate H is secured rigidly a disk n, (see Figs. 7 and 13,) over which a gear-wheel N, Fig. 6, is placed. The front face of this gear-wheel has rigidly secured thereto an outwardly-projecting stud or block or, located between that portion of the wheel from which the teeth are absent, and almost at right angles therewith from the center of the wheel is secured, but nearer the periphery of the wheel, the projecting portion 42 which is curved, one end tapering, as fully shown in Fig. 6. The disk or has a raised portion 01 formed thereon, the height of said portion being substantially the same as the height of the raised projection n and n of the wheel N. Above the portion a is secured, by means of a shouldered bolt, a gear-wheel 0, so as to turn upon said bolt, and the rear face of this wheel 0 has projecting studs oand o placed at equal distance from the center of said wheel, so that they alternately engage with the stud-or projection n on the toothed wheel N. The outer edge of the gear-wheels N and O .are on a line with each other, so that they will both mesh -with the worm E. The cam 0 being rigidly secured to the wheel 0, moves therewith, and with the faces of said cam the projections k and k engage to reciprocate or move laterally the bar K.

To the rear side of the plate H is secured a lever or dog P, Figs. 2 and 3, which is pivotally secured to said plate bya pivot-bolt p. The normal vertical portion of this lever carries at its upper end a gravity or spring-actuated pawl p, which is adapted to engage with the toothed wheel M and advance said wheel forward one tooth. The member P before referred to, of the lever is substantially at right angleswith the vertical portion and carries near its outer end a projecting pin 19 which passes through an opening in the plate H and engages with the V-shaped slot in the bar K, so that when said bar is thrown by the rotation of the cam O the upper end, which carries the pawl, will be thrown or moved so as to advance the wheel M. This lever P is provided with a spring 19 for retracting the same and maintaining it in position.

To the rear side of the plate H is also secured a lever B, comprising members R and R This lever B is pivoted to the rear of the plate H by a bolt, and the member R extends upwardly, and near its end is bent to engage with the projecting stud m, formed on the arm m, by which it is operated or thrown. The outer member R is bent to lie over the periphery of the wheel N and be out of engagement therewith, and this end carries a spring-actuated pawl 0'', which engages with the periphery of the wheel 0. The lever B is also provided with a spring, as shown in Fig. 2,for drawing the arm or m'emloerR down, and when drawn down this member of the lever bears upon the stud to which the spring of the lever R is secured. Vhen either of the pinions 3 or at, which are mounted on the slotted shaft E, so as to turn thereon, is in engagement with its clutch, said clutches being thrown in engagement by the movement of the bar K, the vertically-slotted shaft 6 will be turned to actuate the pinion 7, which is.

geared to the worm-shaft 8, and upon this worm-shaft, which extends horizontally parallel with the brush-frame,in which it bears, is a sleeve 9, which engages with the spiral groove of said shaft, and keyed to this sleeve 9 and carried thereby is a beveled pinion 10, which meshes with a pinion 11, mounted on the center shaft of the brush-carriage, this shaft also carrying a cog-wheel 12, which meshes with a rack-bar O on the horizontal brushcarrying frame. The center shaft of the brush-carriage is suitably mounted in bearings, which are connected to said carriage (3, which travels in the grooves 0 formed in the beams G O of the brush-frame. An angular plate XV extends from one of the side pieces of the carriage C over the rack-bar, and is provided with an arm which embraces the IIO beveled pinion 10, and also with an arm forming a bearing for the center shaft of the brushes.

The brushes S and S, Figs. 1, 2, and 9, are mounted on a rocking frame and pivoted to the center shaft, and these brushes are geared to the cog-wheel on the center-shaft by means of pinions, as shown in Fig. 2, so as to rotate in unison without interfering with the rocking motion of the brush-carriage. Thepaint is supplied to the centerbrush through a flexible pipe or hose, which extends to a suitable reservoir, and thispipe is connected to a valved bulb t, Figs. 1-0 and 11, which is also connected to a pipe T, which lies over the center brush S, and is perforated adjacent thereto. The center shaft of the brush-carriage is provided with a cam T, which is adapted to engage with a wheel on the end of a reciprocating shaft t, which is mounted in suitable bearings secured to the brush-carriage, so that said shaftwill be caused to reciprocate and press upon the bulb to force the paint out of the perforated pipe T upon the center brush, i

from which it is distributed to the other brushes. This shaft t is encircled by a spiral spring, which holds the same normally in contact with the cam,.and it is also provided with a projecting arm t Figs. .9, 10, and 11, by means of which it can be raised out of contact with the cam, as desired, by simply pulling it away from the cam against the power exerted by the spring and acting on the reservoir to expel such paintas may be in the same, but cutting off further supply by forcing the upper valve to its seat. The bearing-plate by which the shaft 15 is secured to the frame can be adjusted thereon so as to give the proper bearing or stroke to the reciprocating shaft.

To the brush-carriage are secured piv' otcd arms U U, provided with rollers u u at their ends, and with wedge-shaped portions a, which are adapted to engage with a slidingbar U. These curved bars are held normally against the surface of the building by spiral springs attached to the arms and to the boxes in which the bar U moves, and this sliding bar U is operated by a lever V. This lever V, which has a member '0, is pivoted to the brush-carriage, and the end bears upon a cam (1 attached to the center shaft, so that when the movement of the carriage is changed or reversed the cam will throw the member 1; of the lever, which bears upon the cam, either up or down, so that the member 0; will throw the sliding bar U and raise one of the curved arms, while the opposite arm is permitted to come in contact with the surface of the building.

When there is a depression in the building, as a window-frame, one of the ends will move in said depression, and the end coming in contact with the projection i will raise the reciprocating arm 6' out of engagement with the cam T, so that said reciprocating arm will not force the paint out of theperforated tube 25, except to the extent previously mentioned. Every time the brush-carriage changes the direction of its movement this carriage is tilted and the rotary brushes engage with each other, so that the paint placed upon the center brush is distributed to the end brushes, and the paint deposited by the center brush is smoothed and laid even by the brush following it.

In practice the operation of my invention is as follows: The posts A and cross-beams A of the main frame are adjusted slightly greater than the height and width of the surface to be painted. The clamps upon the cross-beams A are then adjusted and secured to the edge of the building, as previously stated, by causing the padded portions a to bear against the side portions of the building adjacent to its front, so as to maintain the apparatus in a vertical position, and the paintreservoir is secured to the uppercross-beam A or other desirable point. The arm an, which extends over the disk M, is placed by raising the hollow knob in one of the desired perforations, and the adjustment of thisarm governs the transverse travel of the brush carriage and brushes, this arm engaging with the trip bar or lever so as to advance the intermittent toothed wheel 0, to which thecam O is attached, at the proper time. When the parts-are so organized that the pinion 3 is in gear with the beveled Wheel j, the shaft E is rotated and the vertical grooved shaft 6 will be turned to rotate the spirally-grooved shaft 8, which will cause the brush-carriage to be moved between the bars 0 O of the brush-carrying frame. When the brush-carriage reaches near the limit of its movement, the arm at will engage with the lever B and will raise the same to advance the member R thereof, which carries the pawl and throws the wheel 0 in engagement with the worm, and as this wheel is turned it will by reason of the studs 0 and 0' engage with the projection it of the wheel N and advance said wheel. The cam O, engaging with the projections k and k on the bar K, will move the bar so as to carry the clutch h out of engagement with the pinion 3 and throw the clutch it in engagement with the pinion at. This changes the direction of the travel of the carriage without changing the direction of the rotation of the driving-shaft E. \Vhen the bar E is thus moved and the shaft rotated, the gearwheels M, N, and 0 will be in engagement with the worm, and as the wheel N turns, the projection n on the face thereof will come in contact with the horizontal bent end of the arm I, which is attached to the plate II, so as to throw said bar out of engagement and throw the clutches g and g out of engagement with the pinions 1 and 2 to prevent the rotation and upward travel of the brush-carrying frame. These clutches are thrown into engagement with the aforesaid pinions by a spring 72 and said clutchescan be held permanently out of engagement by throwingthe lever 2' upwardly. The wheel N is rotated at the proper time by the studs 0 and 0 coming incontact with the projection 47,.

The understanding of the operation of the device will be simplified by bearing in mind that the movable bar K operates the clutches which mesh with the pinions for turning the grooved shaft 6, from which the brush-carriage is caused to travel, and this bar K, by means of the V-shaped slot, also governs the lever P, which advances the wheel M, which engages with the worm. The bar G and its continuation, moving on plate H, operate the clutches which engage the pinions 1 and 2 for turning the screw-threaded rods by which the brush-carrying frame which supports the brush-carriage is raised or lowered. When it is desired to raise the carriage the lever 'i can be raised to draw the barto one side and hold the clutches permanently out of engagement.

hen the device is in operation and the lever placed as shown in Figs. 1 and 4, the

until the top of the frame is reached.

\Vhen it is desired to operate the brushes independently, the dog e which secures the worm E to the grooved shaft E, may be thrown out of engagement with the groove 6. The brushes can then be operated to move either backward or forward; or by operating the lever I the screw-threadedrods D may be turned to raise or lower the brush-carrying frame.

The operation of the rotary brushes will be clear from the foregoing description, referencc being had to the accompanying d rawings.
