T 0 all whom it may concern Be it known that I, JOHN J. l lnzninvoon, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State or Pennsylvania,have invented certain new and useful 1m arovements in Transfer Means; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in transfer devices and its primar object is the provision of a simple, durable and etficient device of. the hind adapted to receive work from the forward side of a metal rolling machine and elevate it to a point above the rolls of the machine so that it may be received by he'operator to be again passed through the rolling machinebr through another machine, as desired. 0 y

The invention has for a further object the provision of a transferring device of the character stated in which the receiving tables may be readily moved from one horizontal plane to another horizontal plane and the positions of the tables reversed. to carry,

articles thereon with the minimum expenditure of time and energy.

The invention has for a further object the provision of a transferring device of the character stated which may be especially adapted for use in rolling mills, warehouses or other establishments and which will require the minimum amount of space and may be readily operated. U

lVith the foregoing and other objects as will appear as the description proceeds, the

invention consists in the novel construction;

combination and arrangement of'cooperatmg elements as hereinafter more specifically set forth, claimed and shown in the accompanying drawings, forming a part of the present application and in which:

Figure l is a perspective side view oi a transferring device constructed in accord ance with my invention, the device being shown with one of its tables in a receiving position and the other of the tablesin a delivering position with respect to a pair of rolls of a metal rolling machine.

Fig. 2 1s a similar view lllustrat ng the manner in which one table moves from a receiving to a delivering position and the other tables moves from a deliver ng to a receiving position,

Fig 3 is a detail transverse section through the main pullin shaft of one of the tables. a

Fig. L is a fragmentary top plan view of one of the tables vshowing a portion of the other table in transverse section and at right angles to the first table to better illustrate the relation between these two tables.

Big. 5 is a detail longitudinal section through one of the tables.

Figs 6, 7 and 8 are top plan, views,"respectively of one of the tripping standards. I j

In Figs. 1 and '2 l have illustrated the transfer device designated generally by 1 as used in connection with a set or" rolls indicated generally by A of known type, these rolls adapted to receive between them articles which are 7 pressed or rolled thereby, these articles being delivered to lower tables of the transfer device and being then elevated by this device and delivered onto theupper series of rolls so as to be returned to the inlet or feed end of the set of rolls in the known manner. i The transferringdevice may be equally well used in connection with a plurality of elevators such as used in connection with warehouses and similar establishments for receiving articles from one elevator and transferring these articles to tion which is reciprocally mounted upon a track tor movement toward the set of rolls A. Track 8 is supported by a suitable foundationv or floor l through which extends an elongated slot 5 positioned centrally oi the track, this slot accomniodating a le'ver 6 which is rockably mounted at its lower end on a sh aft? supported by suitable bearing blocks 8 mounted beneath the floor. The upper end of his lever is connected by a link 9 to a bracket l0 secured upon the rear end bar of the carriage 2. The lever is connected intermediate its ends by a link 11 to a disk 12, eccentrically thereof, this disk being secured upon a shaft 13 rotatably supported byra bearing standard 15 positioned beneath the floor 4:, this shaft .bein rotated in an suitable manner. 2B

is y

side and end and away from,

site corners with upwardly extending spaced bearing standards 16 provided at their :up-

per ends with bearing sleeves 17 through each of which is rotatably'mounted a stub shaft 18. A connecting link 19 is secured on the inner endof this shaft and is pivotally secured at its, opposite ends to upper and lower substantially U-shaped or rectangular frames 29 of suitable construction, these frames 20 being open at their forward or inner ends. An operating arm 21 corresponding substantially in length to link 19 is secured upon the outer end of shaft'18,

this arm being provided at each end with a same horizontal plane.

Tripping and guide standards 23 are mounted at opposite sides of track 3 and are so placed as to be at the diagonally opposite corners of carriage 2 when the carriage is in its inner or receiving and delivering position as illustrated in Fig. 1. Each of the standards 23 is provided with an inclined upper portion 2 1 contiguous to a horizontal portion 25 at its lower end and a vertical stop element 26 at its upper end. On its inner face the standard is provided with two spaced arcuate flanges 2? which form an arcuate guideway 28 adapted to receive the roller 22 at the lower end of arm 21, thelower flange "27 being provided with an opening or cutout at. its lower end which is normally closed by a dog 29 secured on the inner end of a stub shaft 30 rockably mounted in the standard, this stub shaft being provided at its outer end with an arm 31 secured thereon member 24, as more clearly shown in Fig. 7.

upon which is mounted a counterweight 32 for norn ally holding the dog in raised position. The upper end portion of the upper fian ef27 is imilarly cut away and is normally closed by a dog 33 which is held in operative position by gravity, outward movement of this dog beyond the vertical being prevented by a stop element or lug 3 1 formed upon the standard. [his upper dog also serves to close a cutout or opening formed in the lower portion of the inclined The ends of the inner or forward connectng link 19. are secured to shafts 35 which extend transversely of the forward ends of frames 20 and are rockabletherein.

shafts 36 which are rockable in the outer ends of the frames 20, the frames being thus "connected and supported by the linksand the parts associated therewith so as to be movscribed.

The. ends of the outer link 19 are securedto able through circular paths of movement, the links 19 being of slightly greater length than the length of the frames 20 so as to readily permit this movement. 33;; rotating the stubshafts 18, the relativepositions of the frames 20 may be thus readily alternatelyreversed by a continuous operation. A tubular member 37 (Fig. 3) such as a section of pipe, is loosely mounted upon shaft 35, this member being provided with diametrically opposite pairs of cars 38 between which are secured the inner end por tions of receiving bars 89, these bars being disposed in parallel spaced relation and extending longitudinally of frame 20 so as to form, together with shaft 86 and the parts associated therewith, a receiving and supporting table which is well adapted to receive'articles discharged from between the rolls of the series A. Bar 39 is, secured be tween the cars 38 by a suitable securing bolt 40, this bolt also providing a pivot for-a weight member e1 which is adapted to overlie the shaft 85 as in Fig, 3, one of these weight members being provided at. each side of the shaft so that the'lower member normally hangs in substantial vertical position and tends to rock the tubular member 87 about shaft 35 so as to move bars 39'1nto horizontal position in a manner to be de- Shaft 35 is provided adjacent the inner face of each sidebar of frame 20 with a cam is secured thereon which adapted to engage a roller 43 mounted in the inner endof the trip rod 4 1 which is. slidable through supporting straps 15 secured to the side bar of the frame. h outer end por inc 7 tion of this bar is flattened and is bent downwardly and outwardly to provide an element 46 which is secured to an angle bar 47 extending"- transversely of the outer end of frame 20 and slidable upon roller sleeve e8 loosely mounted upon a rod is carried by brackets 50 secured to the inner face of end bar 29* offrame 20 and projecting downwardly through slots 51 provided through the bar: 47. The brackets 50 support, at their upper ends, a rod 52 upon which is rockahly mounted a locking plat-e53. the inner portion 53 of which is inclined downward y and inwardly and is engaged 2y a wire spring mounted about rod 52, this spring serving to nor mally hold the platein raised position with its outer edge portion in engagement with the upper edge of end bar 20" of ti e frame;

The rod 14; is normally held in retracted position by an expansion coil spring 55 mounted about the same andconfined between the outer strap 45 and acollar. 56 secured on the rod. 7 this position roller 4E3'is engaged bycam 42 so as to force the red at Olli-WaICllf, when shaft 35 is rotated. Each of the locking plates 53 is, provided with a slot 57 to accommodate the weight.

forwardly in advance of the upper table of Fig. 1, this upper table being moved downwardly and rearwardly. With tl e two tables in this position, the weight member d1 of the upper table illustrated in Fig. 1 will be engaged by the rearward end bar 2O of frame20 of the forward table in Fig. 2 so as to be raised into substantial vertical position thereby, the weight member 41 which is pivoted at the upper side of shaft 35 in ig. 2 serving, during continued movement of these tables, to rock the bars 39 of the upper table illustrated in Fig. 1, which are shown in vertical position in Fig. 2, into horizontal position. Upon the carriage 2 being moved inwardly soars to be again in the position illustrated in Fig. 1, the rollers 22 at the inner ends of arms 19 will be forced up the inclined elements 24 ofthe standards 23, so as tobe turned into vertical position thereby, these arms being thus moved through one-half of a complete rotation for each complete reciprocation of the carriage. The table which occupies the lowerposition in Fig. 1 is thus raised so as to occupy the upper position, the article which has been received from between the rollers being thus elevated so as to be delivered upon the upper surface of the top series of rolls and fed along the same to the inlet or feed end therei of. In this manner, any number of articles may be readily received and transferred from one level to another for the purpose specified. Upon the carriage 2 being again moved outwardly away from the series of rolls A, and as the two frames. 20 of the tables approach a common horizontal plane, the cams 42 ofshaft 35 engage the rollers l3 so as to force the angle bar or plate 47 out wardly, thus releasing the outer ends of the bars 39 so as to permit the table to be rocked, first into a substantial vertical position as in Fig. 2, this table being then rocked into sub- I stantial horizontal position by means of the weight 41 during continued relative move ment of the twotables. As the table is moved into horizontal position, the outer ends of the bars 39 thereof, which'are beveled for this purpose, engage the beveled portion 53 of the locking plate 53 so as to rock this plate about rod 52, the bars 39 then engaging angle bar at? which has been returned to operative position by the spring 55 and parts associated therewith,after which the plate 53 is rocked outwardly. by the action of spring 541; so as to engage over thebeveled ends of bars 39, the table being thus effectu-o ally secured in horizontal position, as in Fig. 1. In this manner, the two tables may have their relatlve positions alternately reversed,

and this operation is continuous so that a great number of articles may be transferred from one elevator or conveyer to another within a relatively short time. By referring to Figs. at and 5 of the drawings in connection with Figs. 1 and 2, it will be understood that the plate 53 has its main portion extended at a right angle to the frame end bar20 while its beveled portion 53 is spaced above the shaft 36 and this portion must be forced toward the shaft 36 by the beveled ends of the bar 39 as they pass the plate for engagement on the bar 47, when the plate 53 will be immediately returned to normal position by means of the wire spring 54:, over the beveled. ends of the bar 39 and prevent these ends from again moving up: wardly. Also this operation of the twotables is accomplished by the reciprocation of the carriage 2, all unnecessary parts being eliminated and a comparatively simple and positive operation obtained.
