PATENT; OFFICE FARIBAULT, MINNESOTA APPARATUS FOR DIPPING- TABLE LEGS AND OTHER OBJECTS IN FINISHING LIQUIDS Application filed April 13,

My present invention has for its object to provide a simple and highly efficient apparatus for use in dipping table legs and other objects in lacquer, varnish, paint, stain or other finishing materials, and to such ends, generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claim.

While the apparatus is intended for general use, it is especially well adapted for use in coating objects with lacquer, which, as is well known, is very difficult to apply for the reason that it dries very quickly and, if touched, will leave finger marks.

, Furthermore, if an object finished with lacquer is not completely covered, for instance the ends of table legs, moisture will get into the wood and thereby cause the lacquer to scale or chip from the legs. By the use of my apparatus, a plurality of table legs or other objects may be very quickly dipped into lacquer or other finishing material so that they are completely covered, then lifted from the liquid and allowed to drain or drip and dry without having been touched by the operator.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings:

The numeral 10 indicates a portable platform mounted on castors 11 and having an upright skeleton main frame 12. Removably mounted on the platform 10 in front of the frame 12 is a deep and relatively narrow container 13 for holding a finishing liquid material m which may be lacquer, varnish, paint, stain or the like. This container 13 is held by a pair of forwardly-projecting horizontal arms 14 rigidly secured to'the frame 12. Said container 13 is further'held by a'cross tiebar 15 attached to the arms llat the backof said container and a pair of turn buttons 16 on said arms and arranged to be turned into a position in front of said container. By moving the turn buttons "16 into inoperative positions, the container 13 may be removed from the platform 10.

For holding objects to be immergedin the liquid :0 there is provided a pluralityof racks each comprising ahorizontal bar .17 to which is permanently attached a-plurality of independent tongs 18. Eachpairof tongs 18 comprises a pair of edgewise spaced upright legs 19 intermediately pivoted by screws 20 to the bar 17 at the face'thereof. The legs .19, as shown in Fig. 5, have inturned lower ends affording a pair of grapples .21 adapted to hold a table leg 3 suspended by means of a screw 2 in the upper end of-saidleg. Notches 22 are formed in the grapples .21 to receive the body of the, screw 2 so that said grapples ma close under the head thereof. r

The screws 2 in the upper endsof the legs y are parts of the devices provided for attaching said legs to table tops. The grapples on the legs 19, as shown in Fig. 8, are in the form of barbs Mai-ranged to engage a table leg y at diametrically opposite points near the top thereof and hold-thesame suspended.

For operating the legs 19 of each pair of tongs 18 there is provided a hand lever '25 pivoted at .26 to the upper end of one of said legs and having an intermediate cam lug 27 which works in a .cam slot 28 in the upper end portion of the other of said legs. A downward pressure on the hand lever 25, as shown in Fig. 5, will close the grapples 21 under the head of the screw 2 and hold the leg y suspended. The frictional engagement between the cam lug 27 and the respective leg 19 at its cam slot 28, at the completion of a movement of the hand lever to close the grapples, will automatically hold said lever where set. I

The tong 18, shown in Fig 8, is operated and self-locked in the same manner as the tong shown in Fig. 5, with the exception that the grapples 24 directly engage the leg y. Other means than the screws 2 are used for attaching the leg 1, shown in Fig. 8, to a table top.

Each rack 17 has 011 its back a pair of WldG'llOOkS 23 adapted to be placed over the front horizontal member of the crosshead 29 for detachably supporting said rack therefrom. On the sides of the crosshead 29 are upper and lower pairs of notched shoes 30 which co-operate with u right rails 31 on the frame 12. These shoes 30 and rails 31 guide the crosshead 29 for raising and lowering movements and against forward or backward movements. When one of the racks 17 is attached to the crosshead 29, the legs y, held by its tongs 18, are suspended over the container 13 so that they will enter the container 13 without touching the sides thereof.

To hold the crosshead 29'against transverse movement in respect to the frame 12, there is mounted in the crosshead 29, at the back thereof, a notched shoe 32 which 00- operates with an upright rail 33.

The crosshead 29 is held counterbalanced by a weight 34 attached to a cable 35 anchored to said crosshead and arranged to run over a guide sheave 36 on the top of the frame 12. The weight 34 works in an upright trough-like member 37 which forms a part of the frame 12 and to which the rail 33 is secured.

'A pair of supplemental frames 38 are detachably secured, one to each side of the main frame 12 by slot and pin connections 39. An inclined drain trough 40 forms a part of each supplemental frame 38 and is arranged to empty into the container 13.

To dip the legs y in the liquid m, the crosshead 29 is raised and one" of the racks 17 mounted thereon. Said legs Q] are thenindividually attached to the rack 17 by means of the tongs 18. The tongs 18 are so arranged that the legs19 are held spaced from to its original position to carry the legs y out of the liquid 00 and above the top of the container 13. He then removes the rack 17 from the crosshead 29 and places the same on one of the supplemental frames 28 to allow the surplus liquid on the legs y to drip into the respective trough 40 where it is drained back into the container 13. After the surplus material as on the leg y has dripped therefrom, the operator may remove the rack 17 from the supplemental frame 28 and hang the same on a support where the liquid on the legs may thoroughly dry.

What I claim is:

In an apparatus of the kind described, a rack having a holder in the form of a pair of tongs, the legs of the tongs being intermediately pivoted to the rack and having on their lower ends grapples, and a lever pivoted to the upper end of one of the legs of the tong and having a cam lug extending into a cam .slot in the other of said legs, said cam lug being operative to hold the legs where set when operated to close the grapples on to an object to be held thereby.

In testimony whereof I aflix my signature.

each other so that they will be completely 7 covered with the liquid at when dippedtherein. The operator then moves .the crosshead 29 down, against the action of the weight 34,

by pressure applied to said crosshead or the V rack 17, to immerge the legs g in the liquid so that they are completely covered thereby. The operator then lifts the crosshead 29
