APPARATUS FOR HANDLING FORGINGS.

Specification of Letters Patent.

Patented Jan. 3, 1911.

Application filed December 16, 1908. Serial No. 467,792.

To all whom it may concern:

Be it known that I, ROBERT F. DEVINE, of Erie, Erie county, Pennsylvania, have invented a new and useful Apparatus for Handling Forgings, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a sectional plan view of one form of apparatus embodying my invention, the section being taken on the line II of Fig. 2; Figs. 2 and 3 are vertical sections taken respectively on the lines IIII and III-III of Fig. 1; Fig. 4 is a sectional plan view of the trolley and smaller turntable, the section being taken on the line IV-IV of Fig. 2; and Fig. 5 is a detail sectional view showing the cylinder and the hub or support therefor; and Fig. 6 is a sectional plan view, showing a modification.

vMy invention has relation to apparatus for handling forgings during the heating and forging operation, and is designed to provide means of this character by which the piece to be forged can be transferred from the furnace to the forge and properly manipulated under the action of heating, forging or pressing, the apparatus being so arranged as to provide for the full control of the piece under the hammer, press and furnace, and to enable it to be manipulated by the apparatus with substantially the same control as in hand forging.

A further object of the invention is to provide apparatus of this character, which will be capable of handling pieces or forgings of various shapes and sizes.

The nature of my invention will be best understood by reference to the accompanying drawings, in which I have shown the preferred embodiment thereof, and which will now be described, it being premised, however, that various changes may be made in the details of construction and arrangement of the parts without departing from the spirit and scope of the invention as defined in the appended claims.

In these drawings the numeral 2 designates the base of the apparatus, provided with a circular support 3, bolted to the lower part of a circular track 3 and supporting the upper part 1 of a circular track for a turntable having the wheels which travel between the tracks 81 and 4 said turntable having also a central bearing at 5 upon which it turns.

7 designates suitable bracing for the turntable, and 8. are diametrically extending tracks which form the body of the turntable, the wheels 6 being carried by frame end braces 6 of tracks 8 and bearings 6 bolted with I-beam braces 7. These tracks as shown in Figs. 2 and 3, consist of upper and lower pairs of rails between which are mounted the wheels 9 of a carriage or trolley 10, said carriage or trolley being freely movable upon said tracks. This carriage carries a table 11, upon which is mounted a second turntable 12, preferably upon ball bearings 13.

Rising from the table 12 are the four posts or columns 14:. 15 are two cross-heads or slides, each mounted to slide vertically on these columns, and which are provided with bearings 16 for the trunnions 17 of a hub or carrier 18 of a work holder or cylinder 19. The cylinder 19 forms the holder for the piece to be forged, and may be of the character described. and claimed in my Patent No. 740,100 of September 29,.1903, to which reference may be had for a more complete description thereof, or it may consist of suitable tongs 19, such as shown in Fig. 2, and which form the subject matter of my application, Serial No. 467,791, filed December 16, 1908. This cylinder is mounted to slide endwise through the hub or carrier 18, and also to rotate therein, the hub or carrier being provided with one or more sets of anti-friction rollers 20, against which the exterior of the cylinder bears. The cylinder is rotated on these bearings by means of a worm gear wheel 21 driven by an electric motor 22 through the reduction gearing 23.

24: designates springs, which are coded around the trunnions 17 between the hub or carrier 18 and the cross-heads or slides 15. The bearings 10 are in the form of sleeves, which are extended through the slides 15 and which engage slotted arms or housings 25, to which are attached the ends of chains 26. These chains pass upwardly and over toothed wheels on a transverse shaft 27 j0ur naled at the top of the posts or columns 1 1, and thence downwardly and around toothed wheels 27 at the base of the columns, one end of each chain being attached to the arms 25 above the trunnions 17, and the other end of each chain being attached to said arms below said trunnions. The shaft 27 is arranged to be driven by an electric motor 28 supported on a frame 29 secured to the tops of the posts or columns 14.

3O designates springs sealed in the slots of the arms or housings 25 and which cooperatewith the springs 24 before referred to to prevent the thrusts of the forging hammer from being transmitted to the other parts of the apparatus.

The main turntable is revolved through the desired angle by means of the motor.

31 having a pinion 32 driven through the intermediate gearing 33 and engaging the teeth of the rack 34 bolted to lower circular track plate 3 The carriage or trolley 10 is reciprocated on the tracks 8 by means of a motor 36 mounted thereon, and geared to a winding drum 37 around which is wrapped the ends of oppositely extending cables 38, the other ends of these cables being connected to the truck wheel frames 6' of the turntable at opposite sides of the machine, as shown in Fig. l.

The operation will be readily understood.

The main turntable is operated to bring the cylinder 19 into position to receive from the furnace the piece to be forged and to carry it to the forging machine, press or hammer. The motor 36 is then operated to move the carriage or trolley 10 to the desired position on the tracks 8. Smaller angular movements of the piece are effected by turning the smaller turntable 12. The piece is raised and lowered by the operation of the motor 28, and is rotated for rounding up by means of the motor 22. For heavy pieces, the main weight of the piece will preferably be carried by a supporting chain 39 from a suitable overhead crane or other support, as in hand forging, and the motor 28 can then be operated to tilt or tip the piece in a vertical plane. These several movements provide for perfect control of the piece to be forged, which can be of various sizes or shapes, and can, by a proper combination of movements be manipulated by the apparatus with the same freedom as in hand forging.

Instead of mounting the apparatus upon a turntable in the manner described, the carriage or trolley 10 may be mounted upon rails 40 (see Fig. 6), constituting a cranebridge, and mounted on wheels 41 which travel 011 tracks 42 at right angles to the rails 40. The apparatus carried by the carriage or trolley 10 is the same as that shown in the other figures. The cables 38 are in this case connected to the truck frames 43 at the ends of the tracks 40. Upper and lower rails 40 are preferably employed between which the wheels 9 of the trolley or carriage travel. The bridge formed by the rails 40 is moved on the tracks 42 by means of a motor 44. The shaft of the motor carries a pinion 45 whichmeshes with a gear wheel 46 on a shaft 47. On each end of this shaft 47 is a pinion 48 which meshes with a gear wheel 49 attached to the axle of one of the wheels 41. In this construction, the transfer movements are obtained by moving the apparatus longitudinally on the tracks 42, and angular movements by means of the turntable 12.

It will be understood that I do not limit myself to the use of the cylinder 19 asthe means for supporting the work, since this may be of any desired character.

Various other changes may be made in the details of construction and arrangement of the parts without departing from my invention.
