Specification of Letters Patent.

Patented May 7, 1912.

Serial No. 486,788.

To all whom it may 0011 com Be it known that I, REME A. BEAUSEJOUR, a subject of the King of Great Britain, and resident of the borough of Brooklyn, in thecity and State of New York, have invented a new and useful Holder for Liquid-Coating Machines, of which the following is a specification.

This invention relates to that type of liquid coating machines in which the articles to be treated to a liquid coating are held in an article holder and raised and lowered by Huid actuated means, the parts being so constructed, arranged and operated that the articles being treated are so held that the liquid dripping therefrom will be kept from accumulating on any surface of the articles, and the articles will be uniformly coated.

One object is to provide means for steadying the lifting mechanism, so that the operations of raising or lowering may be accomplished without any vibration or trembling of the article holder.

Another object is to provide an improved means for retaining the articles to be coated in the holder.

A further object is to provide improved means for securing the holder to the lifting mechanism.

A practical embodimentof my invention is represented in the accompanying drawings, in which- Figure 1 represents in side elevation, partially in section, an embodiment of my invention as applied to a single dipping tank, the parts being shown in their lowered positions in full lines and in their raised positions in dotted lines, Fig. 2 is a top plan view of the same, Figs. 3, 4 and 5 are enlarged detail front, side and top plan views, respectively, of the means for carrying the article holder and the means for retaining it in its gravitational position, Fig. 6 is a vertical section of the means for locking the holder to the carrying means taken in the plane of the line A-A of Fig. 4, Fig. 7 is a section in the plane of the line B-B of Fig. 4, looking in the direction of the arrows, F ig. S is an end view of an embodiment of my invention, partially in section, the parts being shown in their lowered position, Fig. 9 is a detail front view of the means for engaging and supporting the upper portions of the articles being treated, Fig. 10 is a section taken in the plane of the line C-C of Fig. 9, looking in the direction of t-he arrows, Fig. 11 is an inverted plan view of the article holder, F ig. 12 is a plan view of the same, the parts being broken away, Fig. 13 is a detail side view partially in section of one of the ,clamps for supporting the lower portions of the articles being treated, and its support, and Fig. 14 is a front View of the same.

The dipping tank is denoted by 1 and is herein shown as provided with a floor or other support 2 at its bottom, and a platform 3 near its top. The cylinder 4 of a Huid actuated device is located adjacent to the tank 1. A piston 5 is fitted to reciprocate within the cylinder, 4, and its rod 6 extends upwardly through the top of the cylinder.

The fluid inlet pipe is indicated by 7 and it has a pressure regulator 8 and a pressure regulator gage 9 therein. This inlet pipe 7 is provided with a branch pipe l0 leading to the upper end of the cylinder 4 and another branch pipe 11 leading to the lower end of said cylinder. The iuid outlet pipe 12 is connected to the branch pipe l0 through a pipe 13 having a manually operated valve 14 therein. This outletpipe 12 is also connected to the branch pipe 11, through a pipe 15 having a manually operated valve 16 therein. A manually operated valve 17 is located in the branch inlet pipe l1, and a manually operated valve 18 is located in the inlet pipe 7.

A bracket is carried by the piston rod 6, above the cylinder 4, whichbracket comprises a tubular post 19 surrounding a piston rod 6 and havin@ a horizontal arm 20 projecting from its Tower end; and a diagonally arranged supporting strap 21 eX- tending from its upper end to the horizontal arm 20 at a point between its inner and outer ends. A vertical post 22 is arranged adjacent to the cylinder 4, which post is of suticient height to extend above the top of the bracket when the latter is in its raised position. The top of the post is rigidly secured to an upper support 22* and its bottom rests in a suitable support 4* on the cylinder 4. A pulley 23 is mounted at the top of the -post 22, over which pulley runs the Hexible connection 24 of a bracket counterbalancing device; one end of which flexible connection is attached to the top of the tubular post 19 and the other end to a counterbalanced weight 25. To insure an even vertical movement of the bracket, I provide upper and lower guide pieces 26 mounted on the tubular post 19 and each carrying a pair of rollers 27 which engage the post 22 on opposite sides thereof thus causing the tubular post 19 to remain exactly Iparallel with the post 22 during the vertical movements of the bracket. For this salne purpose and to absolutely prevent any wabbling or vibration of the bracket as it is raised or lowered, I provide a support for the outer end of the horizontal arm 2O which is arranged in the following manner: A flexible connection 28 is attached to the outer end of the horizontal arm 20. It then passes over the pulley 29 conveniently mounted on a suitable upper support 29* directly over the end of the arm 20; thence over the pulley 23; thence over the pulley 30 mounted in the horizontal lug 31 on the upper part of the post 22; thence over the pulley 32 mounted on the horizontal lug 33 near the bottom of the post 22; thence over one of the lower rollers 27; and is then attached to the upper guide piece 26. This flexible connection 28 is drawn taut with the arm 20 exactly at right angles to the tubular post 19, and serves admirably as a support for the arm 20 to prevent any trembling of the bracket in its vertical movements, which tremors might be imparted to the article being coated and mar the article. The horizontal arm 2() is of inverted U-shape in its cross section, as clearly shown in Fig. 4, with its edges 34, 35 turned in toward each other substantially at right angles to the side of the arm.

A carriage 36 is fitted to reciprocate within the arm 20, and it is supported therein by the wheels 37 arranged to ride on the inturned edges 34, 35, of the arm. Any suitable means, such, for instance, as the pins 20* and 20M serve to limit the outward and inward movements of the carriage.

The article holder comprises a skeleton frame having vertical side bars 3S and diagonal side bars 39 connecting the top 40 and the bottom 41. The top of the holder is provided with a plate 42 (Fig. 4) having a hole therein for receiving the sna-p catches 43 carried by the depending arm 44 of the carriage 36 for locking the article holder in engagement with the said carriage. For releasing the snap catches 43 from their engagement with the plate 42 I provide a device comprising a loop 45 and wedges 46. This device is pivoted to the arm 44 in such a position that a swinging movement to the right (Fig. 4) will cause the wedges 46 to pass between the snap catches 43 and the arm 44 thus disengaging the catches from the plate 42.

A spring pressed latch 47 1s hinged at 48 to a 'projection 49 on the lateral arm 2O of the bracket; which latch is provided with a vertical series of catches 50 arranged to receive in one of them a tooth 51 on the top of an article holder', according to the inclination which the holder assumes under the influence of the weight and disposition of the articles to be dipped. This tooth 51 is part of a notch 51* for receiving the spring pressed latch 47 to automatically retain the holder in its proper position longitudinally of the arm 20. The lower end of this latch 47 is provided with a cam 52 which is arranged in position to be engaged by the pin 53 carried by the top of the holder whereby the said latch is removed from its engagement with the tooth 51 and notch 5l* of the holder, as the latter is slid longitudinally of the arm 20 of the bracket to be removed from its position over the tank. The function of this spring pressed latch is to retain the article holder against any swinging movement while it is being lowered or raised, and also to automatically arrestI the movement of thel holder in either direction longitudinally of the arm 20 after the holder has reached its proper position over the tank. To further insure against any swinging movement of the holder, I provide a plurality of series of props 54 pivoted to a projection 55 on the horizontal arm 20. These props are of various lengths and so arranged that when the holder has assumed the inclination controlled by the center of gravity of the holder and articles therein to be dipped, the prop of the proper length will swing its lower end into engagement with the top of the holder. Thus the props 54 coperate with the latch 47 to retain the article holder absolutely against any swinging motion in the tank. The article holder' itself is shown herein as particularly well adapted for use in holding the several parts or' a piano, The bottom 41 of the holder is provided with a plurality of laterally extended cross bars 56 which form supports for the bottoms of the articles to be dipped. Across bar 57 extends between the side bars 39 of the holder, a short distance above the bottom 41. On one or more of these cross bars I provide spring clamps 58 so arranged that they will clamp the several articles to the holder.

The diagonal side bars 39 are provided near their tops with loop frames 59. These frames have holes 60 litted to register with any one of a series of holes 61 in the bars 39, and the trames may be secured in different adjustments on said bars by means ot' the bolts 62 and winged nuts 63. Each one ot these loop frames is provided with a series of spring pressed lingers 64, having pointed ends arranged to engage the tops of the articles to be dipped; the said fin-- gers passing through both horizontal members of the loop frames and having a sliding movement therein. Pins 64* serve to limit the downward movement of the fingers. Each of the fingers is provided with a pulley 65 near its upper end; and pulleys 66 are mounted in the frame intermediate the lingers. A flexible connection 67 passes around each of the pulleys, both ends of which flexible connection are attached to springs 68, mounted in the frame near the ends thereof for tending to hold the fingers at the limit of their inward movement. By this construction I obtain an even pressure on all the fingers and eliminate the necessity of providing an individual spring for each finger.

The positions of the several article holder devices are suoli that the articles are so held that the liquid in dripping therefrom will run along an edge to a corner and drop therefrom, thus avoiding any streaking of the article or unevenness of the coating.

For supporting the article holder when it is removed from the dipping mechanism, and facilitating its removal from one place to another, I provide small ball bearing casters 69 and large ball bearing casters 70 which may be removably secured to the bottom 41 of the holder by means of clamp screws 71. I preferably arrange the small casters approximately at the corners of the bottom of the holder and the large casters about centrally of the long sides of the arm, as shown in Fig. 11. Vhen the holder is at rest on the casters, it will be supported by the two large casters 70 and the two small casters 69 at either end of the bottom, according as the center of gravity of the holder and articles contained therein is at one side or the other of the large casters. My object in providing two large casters is to facilitate the turning about of the holder as it is rolled from one place to another. This turning is very easily accomplished if the holder is first balanced on the two large casters only.

In operation, presupposing the fluid to have been admitted to the under side of the piston 5 and permitted to escape from the upper side thereof for causing the piston rod and the bracket thereon to be raised to the limit of its upward movement; the carriage 36 is moved out to the end of the horizontal arm 20 and the article holder secured thereto. The articles to be dipped are then carefully secured within the holder, and the latter and the carriage from which it is suspended are moved inwardly to a position directly over the tank. The holder will seek its center of gravity as it is being moved along the arm 2() and the struts 54 and latch 47 will automatically retain it in that position. The Huid is now admitted to the top of the piston 5 and permitted to escape from the bottom thereof,

thus forcing the bracket and the holder carried thereby downwardly for immersing the article in the liquid in the tank. When it is desired to raise the articles from the tank, fluid is admitted to the under side of the piston 5 and permitted to escape from the upper side thereof, thus causing the piston rod and the bracket thereon to slowly rise, and with them the article holder. The guide pieces 26, with their rollers 27, engaging the post 22, in conjunction with the counterbalancing Weight 25 and the flexible connection 28, insure an even vertical movement of the bracket and holder without the slightest degree of quivering or trembling, thereby producing an absolutely smooth and even coating, and hence a very superior rfinish to the article. After the articles have been raised from the tank, and at the proper time, the carriage and holder may be moved outwardly along the arm 20 until the holder is beyond the tank, the casters adjusted to the bottom of the holder, the latter disengaged from the carriage and rolled to any desired location, where the articles may be allowed to dry.

While I have shown one form o-f uid actuating means for raising and lowering the article holder, it is to be understood that 1 contemplate the use of any suitable means for accomplishing this result. It is also evident that changes may be resorted to in the form, arrangement and construction of the various parts of my invention without departing from the scope thereof, hence I do not wish to limit myself strictly to the form herein shown and described, but
