HERBERT RUFF, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR O11 ONE-HALF TO LEON Gr. BUCKWALTER, O3? MERGHANTVILLE, NEW JERSEY.

PLATEEEOVING MECHANISM FOR lR-ESSES, PUNCH-TEE}, SHEARS, AND THE LIKE.

Application filed July 12, 1.918, Serial No. 244,660. Renewed May 21, 1921 To all 1072 0712, may cwiccwi:

Be it known that l, Hniuunrr Burr, a citizen of the United States, residing in the city and county oi Philadelphia, State of Pennsylvania, have invented a new and useful Plate-Moving Mechanism for Presses, Punches, Shears, and the like, of which the following; is a specification.

In the handling of plates of sheet metal, such as are commonly used in shipbuilding, boiler plants and the like, in respect to the large power punches, shears or presses employed, it is well known to those skilled in the art that these plates are frequently eX tensive in area and are heavy and unwieldy to manipulate with respect to the press, punch, shear or the like, frequently requiring the assistance of several laborers in ad dition to the operative of the punch or press, in order to properly position them With respect to the punch, shear or other implement.

It has heretofore been the practice to man ipulate or joggle these plates and position them with respect to the punching, pressing or shearing implement either through the aid of several laborers or by a type of machine, which takes up considerable space, is somewhat cumbersome and whose first cost is greatly in excess of my present invention which is designed to obviate the foregoing}; disadvantages and consists in its bread aspects of a power-driven, self-contained and readily portable plate moving mechanism for moving plates in any desired direction in a horizontal plane with respect to power or hydraulic presses, punches, shears or the like.

In carrying out my invention, I employ a suitable portable framework on which is supported an electric or other motor connected by suitable gearing to a plate actuating wheel, which is located below and. normally out of contact with the plate, said wheel having its periphery roughened or serrated and being adapted at the will f the operator to be intermittently or continuously rotated and capable or" being simultaneously raised into contact with the under surface of the plate so as to propel or actuate the latter horizontally in the de ed direction, suitable means being provided for lowering and changing the vertical line of rotation of said actuating wheel, so that the 1&21.

plate can be actuated in any desired lateral direction, forward, back or sidewise, or diagonally according to requirements.

To the above ends, my invention consists of the novel construction of a hardened, peripherally notched or serrated wheel revolving intermittently or continuously about a horizontal axis, power cing taken from a small electric or other motor equipped with suitable speed reducing mechanism in con junction with manually operated means ander the control of the on: ator tor ra'sing and lowering and changim the line of rotation of said wheel with respect to the plate, according to requirements. The electric motor can be operated continuously or intermittently desired, according to requirements, by means of a push button, switch or the like of any conventional type which can be conveniently lo cated with respect to the hand oi the operator, so that a single operatr can efliciently manipulate the punching and plate n'ioving mechanism with one handle or hand.

It further consists oi": the novel construc tion of vertical shaft carrying the plate fiCtlllltll'lfl wheel, a (rear keyed to the lower portion of said sha't't and a manually operated segment in mesh wit id rear for changing the position of said iertical shaft and wheel,

it further consists of the novel combination of the plate actuating wheel. a vertical snaft therefor, a li irally movable handle and means carried by said handle for elevatinc or lowering said shaft and wheel during the rotation of the latter.

For the purpose of illustrating my invention, I have shown in the accompanying drawing one form thereof which is at present preferred by me, since the same will be found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be varionsly arranged and organized. and that my invention is not limited to the precise arrangement and'organization of these instrumentalities as herein shown and described.

Figure 1 r oresents a side elevation of a plate moving mechanism for moving plates in a horizontal plane, embodying invention.

Fig. 2 represents, on an enlarged scale, a

side elevation of a portion of Fig. 1, certain oi the parts therein being shown in section.

Fig. 3 represents a perspective view of a portion of the-plate moving mechanism in detached position.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings,

1 designates my novel construction of plate moving mechanism for power punches, presses, shears and the like, the same comprising a suitable portable supporting frame 2, consisting oi a base portion 3 and an upright rear portion l, which has a laterally, forwardly extending; bed 5, on which is supported asmall el ctric or other motor 6, which may be of any conventioiuil type and adapted to be continuously or intermittently rotated, as will be evident to those skilled in the art.

7 designates the motor shaft, which carries the outer and inner spur gears 8 and 9, which are in mesh with the spur gears 10 and 11 respectively, which are mounted on the shaft 12, which rotates in the earings 18 on preferably the top of the motor 6, said gear 9 being loose on the shaft 7 and travelinoa much lower speed than said shaft.

it will be noticed that the gears 8 and 11 of relatively small diameter as compared 7 with the intermeshing gears 9 and 10, for the purpose of reducing; the speed of rotation of the bevel gear 9 and the bevel gear 1% thereon to the desired extent, said gears 9 and let being connected by the sleeve 7* loosely mounted on shaft 7.

l5 designates double bevel gear whose lower .o'ear "eeth 16 are in mesh with the bevel gear lid and whose upper teeth 17 are in mesh with the bevel gear 18, which is secured to or integral with the hardened, periphei llynotched or serrated plate actuatiuer ii wheel l5), who: outer periphery rs as best in Figs. 2 and 3, being roughened, serrated or notched, said wheel ii) a l near 1.8 being; f eely revoluble upon the horizontal shaft or stud 21, which pro e's laterally from the top of the vertical shaft .2, which has its lower portion of reduced (llfillilCiGl' nd is ro 'vatably mounted a in the vortica. bearing 2-i the shoulder 25 serving a stop to arrest or limit the downward movement of he parts 22, and particularly to determine the normal position of the wheel 20, The double bevel gear 15 composed of the gears 16 and17 revolves loosely on its shaft or hearing 22.

designates a pinion which is fast to the shaft and which is engaged by the curved rack or segment 27 mounted on the arm which is ttulerumed at the point 29 and terminates in the handle 30. V

31 designates a manually operated lever normally retained in the position seen in Fig. 2, by the spring 32, said lever being pivoted at 33 to the link 34:, whose lower end 35 is attached to a toggle or cam member 36, tulcrumed at 3? and having its upper end in contact with the under side of the bottom ilange or terminal 38 or" the shaft 23.

39 designates a plate to be punched, sheared or otherwise treated and L0 desig nates a punch or press of any conventional type, It will be understood that only a slight upward'movement oi the shaft 22 and its adjuncts is required to bring the plate joggling' wheel 19 into contact with the bottom of the plate 39, and that the gears 14: and 16 are so constructed in practice that they will be in mesh at all times.

1 have shown in the present instance .a simple form of cam or eccentric 86 employed as a raising and lowering device for the shafts 22 and 23 and their adjuncts, said cam being :tulcrumed at the point 37 in the ears ll which may be cast or secured to the ledge 42 but it will be evident that any other equivalent device as a suitable toggle mechanism may be employed if desired.

The operation is as follows The parts normally appear as seen in Fig. 2, the plate actuating wheel 19 being slightly below and out of contact with the under surface of the plate 39 which it may be desired to shift horizontally. The wheel 19 may be revolved continuously or intermittently at the will of the operator by causing the con llllllOUS or intermittent rotation of the motor shaft 7 by any suitable form of push button, switch or the like, 4L3, the construction and operation which, it have'deemed it un necessary to describe in detail.

It will be apparent that so long as the wheel 19 is below and out of contact with the under surface of the plate 39, as seen in 2,.nc movement of the latter can occur. When, however, it is desired to actuate the plate 39, the operator causes the wheel 19 to rotate by closing the circuit of the motor 6 and upon gripping the handle 30 and'pressing" on the lever 31, so that the partsassume the position seen at the left of Fig. '1, it will be apparent that the toggle, cam or its equivalent, 36, will assume the position seen injFia. l, whereupon the vertical shaft composed of the parts 22 and 23, the gear 26, the horizontal shaft 21 and the wheel 1.9,will be elevated, until the latter is in contact with the under surface of the plate 89 and the latter will then forward, rearward, sidewise or diagonal direction to the desired extent at the will of the operator, it being understood that gears 17 and 18 are so constructed that their teeth will always be in mesh when the wheel 19 is in its raised position, as seen in Fig. 1, or in depressed position, as seen in Fig. 2.

The spur pinion 26 being fast to the upright shaft 23 and the horizontal shaft or stud 21 carrying the wheel 19 being secured to the shaft 22, as will be understood from Fig. 2, it will be apparent that when the handle 80 or" the arm 28 of the segment 27 is moved laterally or horizontally about its iulcruni point 29, axial rotation to the desired extent will be imparted to the pinion and shafts 22 and 23 and their adjuncts, so that the said hardened notched or serrated wheel 19 will be rotated about a vertical axis consequently permitting it to assume any desired position at the will oi? the operator. -1 do, when the notched wheel 19 is For e i later-any rotated 180 degrees from the position seen the top of its periphery then travels in a direction opposite to that of its original position and hence a reversal of the line oi travel of the plate is accomplished ,iy merely turning the long handle 30 t re c h a relatively small are. When the il shaft composed of the members 22 id 23 is depressed by releasing the hand ,e'rip or lever and cam or toggle 36 or its eqiiivalent, the parts will assume the normal position seen in Fig. 2 again, whereupon the not-shed wheel 19 is disengaged from the bottom surface of the plate 39 and the latter remains at rest.

It is obvious that the motor can be operdied continuously or at intervals as desired, v placing a push button, switch or the like on the hand lever 30. and, if desired, the entire device and particularly the gearing may be contained within a light sheet metal casing.

desired, further control can be effected by placing a push button switch on the handle 3 to control the electric solenoid oi the customary construction which operates the or aging clutch of the punch if power or n or the controlling valve in the case of a hydraulic punch, whereby with this latter arrangement one operator can completely manipulate the punching and inoviu o the plate by one hand and where an ole 10 current is not available, a small pneumatic engine as the motor of a pneumatic di'll or the like can be substituted. for an electric motor, as will be apparent to those skilled in the art.

I have deemed it unnecessary to describe in deiwil these various en'ibodinients of the use c. 11y invention as their general con struction and mode of application will be iijiiilcnil to those skilled in the art.

will be seen from the foregoing that my present invention is light and portable and can be readily movedfrom one machine to the other according to whichever character of machine may be temporarily in use, as a punch, press or shear, and if desired the rear upright as i can be bolted or clamped to the front 01"" the punch, press or shear which may be in use.

In practice, I may make the bed or base may make all the parts 4; and

. single casting as seen in Fig. 3. in i 2, l have shown one convenient form of mounting the push button, switch or its equivalent 43 upon the handle 30, said push button being electrically connected to the motor by a two wire flexible cable suitably fastened in place by small. insulating clips as 45, so arranged as to permit the :irec lateral movement of the handle 80 about the fulcrum point 29. 46 designate: standard lamp socket or other plug or any suitable electric current tapping device, which is secured to the double wire flexible cable 47 which is connected at its other end as 48 to the power terminals of the moto said cable serving to conduct power to the motor 6 and being preferably made so as to be adapted to the conventional wiring of the building or shop where the device installed. 7 l have omitted the PUSll-lfili} ton, wiring and their adjuncts from 1 for the sake of clearness of illustration but it will be apparent from Fig. 2 that the motor can run intermittently or continuously at the will of the operator and its operation can be controlled by the same hand which positions the plate actuating wheel 19. i am the first in the art to employ a device of this character and my claims thereto are to be interpreted in accordance with the scope accorded to inventions of this character;

It will now be apparent that I have de vised a novel and useful construction oi a plate moving mechanism for presses, punches and shears which embodies the features of advantage enumerated as desii. in the statement oi the invention and the above description, and while I have, in the present instance, shown and described a preferred embodiment thereof which will be found in practice to give satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars without departinn from the spirit or scope or the invention or sacrificing any of its advantages.
