6 Claims. (Cl. 101-35) This invention relates to a machine for'making impressions, such as colored impressions on surfaces, and particularly on surfaces lying in several dilferent planes on a piece of work having such surfaces. Said invention also relates to a machine for making indentations on said surfaces.

It is the present practice to use a job printing press for applying colors to an object. Such a machine can 'be used only to apply a single color at one time to a surface and can only make such an impression on a surface lying in a single plane. Successive independent operations are therefore required for each color applied to a surface and for each plane in which surfaces may lie. This results in a considerable duplication of effort with the work being printed upon having to be handled for each separate operation. Such duplication of effort can be eliminated or avoided by the application of a plurality of colors at one time to a surface lying in a single plane or to surfaces lying in a plurality of planes. It is desirable therefore to have a machine which can make such an application of color.

It is an object therefore of this invention to provide a machine adapted to make impressions on a surface or on a number of surfaces lying in different planes in a single complete operation.

It is an other object of this invention to provide a machine having a plurality of means for respectively applying colors to a surface of a piece of work and a member for moving said work so as to be successively operated upon by said means.

It is also another object of this invention to provide a machine as set forth in the preceding paragraph, and means for holding said first mentioned means in different vertical positions for applying said colors to surfaces on the work disposed in different planes.

it is still another object of this invention to provide a machine for applying colors to surfaces of a piece of work, which surfaces lie in different planes, comprising spaced means for respectively applying said colors to said surfaces, means for moving said object to be successively operated on by said means, and means for operating said last'mentioned means.

It is a further object of this invention to provide a machine having spaced means for respectively applying colors toa plurality of surfaces of a piece of work lying in a plurality of planes in a single complete operation and movable in paths to engage said work, an endless memher for moving said work so as to be successively oper'ated upon by said means,and means for, operating said endless member and said means.

l'tYis a more specific object of this invention to provide amachine for applying colors to surfaces'of a piece of work in a plurality of different planes comprising a supporting. member, members in spaced relation carried by said supporting member and movable in paths for respectively applying colorsto said surfaces, means for gespetively holding said. spaced members in different 2,825,278 Patented Mar. 4, 1958 vertical positions so as to operate on surfaces in different planes of said work, an endless member moving about said supporting member for moving said work to be successively operated upon by said spaced members, and means for operating said endless member and said spaced members.

There may be two or more pairs of upstanding members 55-56 with parts carried thereon identical to those above described, and each of such assemblies is here referred to as a printing element. In the embodiment of the invention here disclosed there are two printing e1ements, the second of which is spaced rearwardly of said above described printing element. The parts of said second printing element are identified by the same characters as are the parts of said first printing element with the exception that an impression roller 160 is provided in place of said impression member 74d. Said impression roller is secured on shaft 72 and is preferably formed of a resilient material and is particularly adapted to apply color to a surface. Shaft 72' is identical to shaft 72 and has secured thereon a sprocket 149'.

Adjacent sprocket 23 secured on shaft 20 is a sprocket 165 of substantially the same diameter. A shaft 81' is provided identical to shaft 81 but having secured thereon a sprocket 165. A link chain 168 will pass over said sprockets 165 and 165'. A second idler identical to the first one describedis provided to take up the slack in said chain 168. Secured to an outer end portion of said shaft 23 is a sprocket 1'70 of rather large diameter.

Mounted to the under side at the rear of said member is an electrical motor 175 and the same is held secured by bolts 176. Said motor as here disclosed has a drive shaft 178 and a sprocket 184? secured on said shaft.

Passing over sprockets 170 and 180 is a link chain 132.

Said motor will be connected to a source of electrical energy by a conduit 182. A switch 185 is mounted at the forward end of said member 19 Where it is easily reached by the operator. A conduit 186 connects said switch with motor 175.

In the instant operation, applicants device will be adapted to apply a different color on each of the two surfaces 53a and 53b respectively lying in different planes. The impression member 74d will be positioned to contact and make a colored impression on said surface 53b. Said impression roller 160 will be positioned to contact and make a colored impression on said surface 53a. Said impression member and said impression roller as portions respectively of said first and second printing elements above described are movable upwardly and down wardly by operation of cranks 64 and 65.

The operator will close switch 185 starting motor 175. Said motor by sprocket 180 and chain 182 will drive sprocket 170. Sprocket 170 by chain 168 will drive sprocket 165 and shaft 81'. Sprocket 113 on shaft 81' will drive sprocket 112, shaft 72" and impression roller 160 secured to said shaft. Sprocket 165 will operate levers and 121 which in turn will rotate inking roller 116. Said roller 160 by contact will rotate rollers 89 and 1. Said last two mentioned rollers by contact will rotate roller 100. Levers 122 and 123 will be oscillated by cams 127 mounted on said shaft 81'. Transfer roller 129 journaled between the upper ends of said levers 122 and 123 will be oscillated between said roller 116 and said roller 160 carrying inkfrom roller 116 to roller 100. Said roller will be moved from side to side by lever 131 in passing on said ink to rollers 89 and 91. Thus said ink is applied evenly to said last two mentioned rollers. Said last two mentioned rollers pass said ink by contact onto roller 83 and thence to the impression roller 169. Said first printing element will operate in the same manner as said second printing element above described and will be actuated by chain 142 passing over sprockets and 140. As said printing'elements are positioned upwardly and downwardly in different vertical positions, said chains 168 and 142 will, be kept tightened by the idlers provided and above described. I When said first and second printing elements have operated sufficiently to have ink supplied to platen 74d and impression rollerltiil, the operator will then place said member 53 on member 50 carried by chains 45 and 46. Said jig 51 on member 50 will be adapted to hold said member 53 in position. Said chains will move said member 53 toward said platen 74d and in passing thereunder said platen will make a colored impression on said surface 53b. Said member 53 will be moved onwardly towards said impression roller and in passing thereunder said roller will make a colored impression on said surface 53a. As said work object is carried to the end of member 14, it will fall off of said jig 51 and into an appropriate receptacle. Said chains 45 and 46 may be tightened or loosened as desired by operation of adjusting screws 35. I

Thus it is seen that I have provided a simple and efficient device for applying different colors to surfaces in different planes of a piece of work in a continuous operation with only one handling required of said work. Said device may be adapted to make impressions in a piece of work by applying pressure to the surfaces of said work in the same manner as it may apply color or it may perform a combination of such operations. Applicants device has been thoroughly tested in practice and 'has been very successful. It is now being commercially produced.
