Fig. 15 is a top plan view of the same, the

holders and their double supporting bracket being shown inv full lines over the dipping tanks and in'dotted lines swung into position for facilitating the insertion and removal of the article holders, and Fig. 16 is a detail sectional view showing the means for attaching the flexible connection of thecounterbalance device to the center of the double -holder carrying bracket.

Proceeding to describe the form shown .in Figs. 1 to 13 inclusive, the dipping tank is denoted by 1 and is hereinshownas provided with a floor or other support 2 at its bottom and a platform 3 near its top. The cylinder 4 of a fluid actuated device is located adja- A piston 5 is fitted tore- ,Z0

cent to the tank 1. ciprocate Within the cylinder 4 and its rod 6 extends u Wardly through the top of the cylinder. T e luid inlet pipe is denoted by 7 and has a pressure regulator 8 and a pressure gage 9 therein. This inlet pipe 7 is provided with a branch pipe 1() leading to the top of Y the cylinder 4 and a branch pipe 11 leading to the bottomof the said cylinder. The fluid outlet pipe 12 is connected to the branch pipe 10 through a pipe 13 having Ia manually operated valve 14 therein. This outlet pipe 12 is also connected to the inlet branch pipe 11 through-a pipe 1-'5 having a manually operated valve 16 therein. A manually operated valve 17 is located' in the branch inlet pipe 11 and amanuallyoperated valve 18 is located in the inlet pipe 7.

A horizontally swinging bracket .is .carried by the piston rod 6 above the cylinder 4., which bracket comprises a tubular post 19 surrounding the piston rod 6, which tubular post has a horizontal arm 20 .projecting from its lower end, and diagonally arranged supporting straps 21 extendingfromjfits upper end to the horizontal arm 2O at different points between itsouter and inner ends.

A vertical post 22 is arranged adjacent to the cylinderV 4, which post is of suiiicient height to extend above the top of thebracket when the bracket is in its raised position. A pulley 23 is mounted at the top ofthe post 22, over Which pulley runs the flexible connection 24 of a bracket counter-balancing device, one end of which flexible connection isattached to the horizontal arm 20 of the bracket and the other end of 'which connection is attached to the counterbalance Weight 25.

To insure an even vertical sliding movement ofthe bracket We provide a guide comlleased from the socket 32.

prising a tubular post 26 which surrounds the vertical ost 22, and a tubular post 27 which. surroun s the tubular post 19 of the bracket. Toinsure an even frictional engagement of the tubular post526 with the post 22, and to reduce friction, the tubular post 26 is provided with upper and lower bushings 28, 29. To properly counterbalarce the bracket by the weight 25 so as to reduce the side strain on the vertical post 22 to a minimum, the upper end of the tubular post 19 ofthe bracket 1s provided with a laterally extended arm 30, over the end of which the flexible connection 24 asses.

'lhe horizontal arm 2O of the bracket is rovided with a spring-actuated pin 31 which 1s fitted to enter a socket 32 in the tubular ost 27 of the bracket guide when the'article holder is suspended in position from the bracket and when the bracket is inits proper position over the dipping tank. The spring 33 of this pin 31 tends to hold the pin re- A carriage 34 is fitted to reciprocate along the horizontal arm 20 of the holder carrying bracket. The article holder comprises a skeleton frame having vertical side bars 35 and diagonal side bars 36 connecting the top 37 and bottom 38 of the holder. The top 37 of the holder is provided with a plate 39 having a plurality of holes 40 arranged in a horizonta line along the plate.' The carriage 34 is provided with a depending arm 41 and a pin 42 .is arranged to pass through the said depending arm and one ofthe holes 40 in the plate 39 for suspending the article holder from the carriage. The top of the holder is further provided with a strap 43 which is bent to form a recess for a yielding stop 44 carried by the horizontal arm 20 of the swinging bracket. In the present instance this yielding stop 44 has a spring 45 foryieldingly holding it at the limit of its downward movement in the path of the strap 43 of the holder. When the yielding sto socket, the holder is yie dingly held in position to be lowered into or raised from the tank. .v

A spring pressed latch 46 is hin ed at 47 to a projection 48 on the horizonta arm 30 Vof the bracket, which latch is provided with a' vertical series of notches 49 arranged to receive in one of them a tooth 50 on the top of the holder, according to the inclination which the holder assumes under the influence of the weight 'of the articles to be dipped. The lower ond of the spring pressed latch 46 is provided with a cam 51, which is arranged in position to be engaged by the pin 52 carried y the top of the holder, whereby'the said latch is removed from its engagement with the holder when it is desired to remove the holder from its position over the tank.

The holder itself is shown herein as particularly well adapted for use in holding the 44 is within its.

several parts of a piano. The bottom 38 of the holder is provided with a plurality of laterally extended cross bars 53 forming sup-l ports for the bottoms of the articles. A cross-bar 54 extends between the side bars 36 of the holder a short distance above the bottom 38, which cross-bar is provided with a plurality of laterally adjustable clamps 55 which are so arranged that they may clamp the heavier articles to the holder. The top 37 of the holder is provided with a plurality of loop frames 56 which are pivotally clamped to the top 37 in any desired angular position with respect thereto, by suitable fastening devices, such, for instance, as thumb nuts 57, engaging pivotal bolts 58, which pass through the sides of the said top 37 of the holder.

Each one of these loop frames 56 is provided/ 'i with a series of spring-pressed fingers 59 having pointed ends arranged to engage the tops of the articles to be dipped, the said iingers v having a sliding movement in the horizontal portion of the loop frame 56. A withdrawing cam 60 is pivoted at 61 on each of the spring pressed fingers 59 in position to engage the lower horizontal portion of the loop frame 56 against the tension of the spring 62 which tends to hold the iinger at the limit of its downward movement. 'When the withdrawing cam is in one position, the 'finger will be yieldingly held against the article and when in its other position, the i'inger will be withdrawn from engagement with they article.

The positions of the several article holding devices are such that the articles are lheld so that when the liquid is dropping therefrom it will run along an edge to a corner and drop from said corner, thus eliminating entirely the streaking of the same on the surfaces of the article, which has heretofore been so undesirable a feature indipping machines.

The spring-pressed pin 31 is forced into its socket 32 against the tension of its spring 33 when the carriage 34 is moved into its position over the tank, by the following means. The carriage 34 is providedwith an inwardly extended push bar 63 arranged to engage the sliding pin 64 in alinenient with the locking pin 31, a yielding connection between the two pins being formed by a coiled spring 65 so that il' the pin 64 should be pressed in when the bracket is not in position over the tank, the spring 65 would yield sufficiently to prevent breakage ol' the parts. When the bracket is swung into a position over the tank, the pin 31 would enter the socket 32 in the tubular post 27 of the guide under pressure exerted by the said spring 65.

In operation, prcsupposing 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 hinged thereon to be raised to the limit of its upward movement;y the ,ius

, ele is being dipped.

bracket is swung horizontally into the desired position for the placing` of the articles in the holder, the holder and its supporting carriage being moved out to the end of the bracket. After the articles have been carel'ully secured in position within the holder, the bracket is swung around into position over the tank. The carriage and the holder suspended therefrom are then moved. inwardly along the horizontal arm 2() of the bracket until the yielding stop 44 drops into the socket in the strap 43 on the. holder, thus positioning the holder over the tank. The weight ol' the articles within the holder will cause the holder to seek its center of gravity on the bolt 42 and as the holder is moved into its position over the tank, the spring pressed latch 46 will be permitted to lock the holder in this position because of the engagement ol' one of its notches 49 with the tooth 5() on the top of the holder. This inward movement oi' the carriage and holder will also lorce the pin 31 into its socket 32 in the bracket guide for locking the bracket against a swinging movement while the arti- The fluid is now admitted to the top ol' the piston 5 and permitted to escape from the bottom thereof, thus Aforcing the bracket and the holder carried thereby, downwardly for immersing the articles in the liquid in the tank. It will be seen that the spring pressed latch 46 because of its engagement with the holder, will prevent any movement of the holder owing to the tendency oi' the articles being dipped to float when immersed in the tank. When it is desired to raise the articles from the tank, the fluid is admitted to the under side ol' the piston 5 and permitted to escape -from the upper side thereof, thus causing the piston rod and the bracket hinged thereon to slowly rise and with them the article holder. The guide for the bracket in conjunction with the counterbalancing of the Weights insures an even vertical movement of the parts, thereby producing a su erior finish to the articles. After the artic es have been raised from the tank and at the proper time the carriage and holder may be moved outwardly along the horizontal arm of the bracket and the bracket may-then be swung into any desired horizontal position for facilitating the removal oli-the articles.

In Figs. 14., 1.5 and 16, we have shown ay modified form arranged for su porting a double bracket, the horizonta arms of which extend in o posite directions' from the guide. In this orm the end of the flexible connection of the counterbalance devicey 1s secured to a sw1vel block 66 mounted 1n the top of the piston rod 6.
