,3am i APPARATUS FOR GREASING lSHEET METAL PLATES Joseph Buzonik, Chicago,`l]l.

Application November 4, 1940, Serial No. 364,208 i claims. (c1. sii-51) The invention relates to an apparatus for greasing sheet metal preparatory to subjecting the material to forming operations.

The practice hitherto followed in the treatment of sheet metal plates consists in taking the plates from an assembled pile and greasing them by hand on both sides, whereupon they are placed in the forming machine to be stamped or punched.

This procedure is cumbersome, expensive and, time-wasting, and therefore obsolete.

it is one of the main objects of the invention to provide an apparatus which eliminates the time wasting and inemcient method of greasing sheet metal plates preparatory to forming the same.

It is a further object of the invention to provide an apparatus in connection with the conveyor mechanism whereby sheet metal plates are placed at one end of the apparatus and subjected to greasing, and thereafter returned to a place not far from the starting end of the apparatus, so that the greased plates may be assembled at a convenient location, eliminating carrying or transportation cf the same to the forming machine.

It is also an object of the invention to provide a gravity conveyor in connection with the greasing apparatus so that no motive power is necessary for the conveying of the sheet metal plates. l

Other and equally important objects will become apparent from a perusal of the invention, which latter comprises the means described in the following specication, particularly pointed out in the claims, and illustrated in the accompanying drawing, in which:

Fig. 1 is a top plan view of the apparatus constructed in accordance with my invention, and

Fig. 2 is an elevational view with parts shown in section.

Referring to the views of the drawing, I designates a truck carrying a pile or stack of sheet metal plates II. A roller co-nveyor, generally designated by I2, comprises longitudinal members I3 and. III, in which plurality of parallel spaced rollers I5 are journaled.

The conveyor I2 is inclined downwardly from its point of origin and is supported at its lowermost end on a tank I in which oil is contained.

A transverse roller Il is journaled in the end walls I8 of the tank and cooperates with the superposed transverse roller I9 whose shaft 20 is journaled at one side in a bearing 2| and projects at the other end through a slot 22 in which a spring 23 maintains the roller I9 in resilient engagement with the roller I'I.

The shaft 24 of the roller I'I and the shaft 20 are provided in the mating gears 25, whereby rotation from the roller I9 is imparted to the roller il,

The shaft 26 is provided with a pulley 26 around which a belt 28 is trained, encompassing a pulley 2 on the shaft of a motor 29, which is energized from a suitable source of electrical energy, not shown, which causes rotation ofthe roller i9 which, in turn, rotates the roller I'i.

A speed reducer 3B is interposed between the motor and the pulley 28 so as to impart proper speed of rotation to the roller I9.

A spray pipe 3l extends alongside of vthe upper roller IS for emission of oil, and leads to a pump 32 adapted to -pump oil from the tank I@ to the spray pipe.

A pulley 33 is in alignment with the pulley 35 on the shaft 2i) and a belt 35 is trained around the aligning pulleys 33 and Eli.

'Ihe tank is provided with a drain pipe 36 for the purpose of draining the oil when necessary to change the same.

A roller conveyor 3l is supported at one end on the tank I8 and, from then on, is inclined downwardly to constitute a gravity conveyor.

The conveyor 31 continues into a semi-circle 38, and thence continues parallel to the conveyor` I2, and leads to a, tank 35, whereto the sheet metal plates are delivered for deposit.

The tank 3S is provided with a drain pipe @9 to enable the reclaiming of the oil dripping from the plates for return to the 'tank I6 by a pipe connection (not shown).

It is evident that, by reason of the U-shaped form of the conveyor 31, the tank 39 may be arranged proximate to a forming machine 4I, diagrammatically indicated in Fig. 1, so that an operator may conveniently remove the greased plates from the tank 39 and place them in the forming machine for further treatment.

It is evident that the apparatus eliminates unnecessary steps in greasing the plates, which is carried out automatically once the plates are placed on the conveyor I2, and the greased plates are then brought back to the operator by conveyor 31 to a, position proximate to the forming machine, for convenient handling of the greased plates.

While th'e drawing shows one embodiment of the invention, numerous changes and alterations said rollers, and a U-shaped conveyor for transporting the greased plates to a point proximate to the starting location to be arranged in stack formation.

2. Apparatus for greasing sheet metal plates, including a pair of greasing rollers, a conveyor carrying the plates past said rollers, a discharge tank proximate to the starting point of said conveyor, and means for conveying the plates from said rollers to said tank to be arranged in stack formation.

3. Apparatus for greasing sheet metal plates, including a pair of greasing rollers, a gravity conveyor carrying the plates past said rollers, a discharge tank proximate to the starting point of said conveyor, and gravity means for conveying the plates from said rollers to said tank to be arranged in stack formation.

4. Apparatus for greasing sheet metal plates, including a pair of greasing rollers, a gravity conveyor carrying the plates past said rollers, a discharge tank proximate to the starting point of said conveyor, gravity means for conveying the plates from said rollers to said tank, and means for collecting the oil accumulating in said discharge tank.
