WILLIAM B. KING, OF NEEDHAIM, MASSACHUSETTS, ASSIGNOR TO UNITED SHOE WIACHINERY CORPORATION, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW ERSEY.

Application filed June 13,

T 0 all whom it may concern:

Be it known that I, WILLIAM B. limo, a citizen of the United States, residing at Needham, in the county of Norfolk and State of Massachusetts, have invented certain improvements in Presses, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several ngures.

This invention relates to improvements in presses of that type in which a pressure applying member is movable into various positions relative to a. bed to apply pressure to difierent parts of stock located between the pressure member and the bed. while presses of this type may be used for many different purposes, they are often used for dieing-out sheet material, and accordingly I have shown my invention applied to a press of this kind, it being understood that it is by no means limited to use with machines for accomplishing this result.

An important feature of this invention relates to the provision in a press of the character described of improved power means for moving the presser member laterally over the work supporting bed, the construction providing preferably a manually controllable member mounted on the presser member and operable to control the said power means.

Practically all types of presses are provided withpower means for causing pressure applying movements of the movable presser member, manually operable means being employed for controlling the power means. It is an object of the present invention to provide a single manually operable means for controlling both the power means for causing lateral movement of the fpresser member over the work supporting bed and the power means for eifecting the pressure applying operations of the presser men her, the said manually operable means being preferablymounted on the presser member for movement therewith, thus providing a controlling means easily accessible to the operator and readily operable to eil'ect'the movements of the presser member in proper sequence.

Another important feature of the invention relates to improvements in a type of press which comprises a work supporting rnnss.

1: simple, compact and most efficient power means for rotating the presser member about the axis of the post comprising a de vice mounted for rotation on the post and providing a movingsurface to which the presser member maybe operatively connected at the will of the operator to swing the presser member over the work supporting bed. Preferably two such devices are mounted on the post for rotation in opposite directions, means being provided for Se lectively connecting the presser member thereto whereby the latter may be moved in the desired direction over the work on the support.

Another feature of importance relates to an improved starting mechanism for controlling the power means for effecting the pressure applying operations of the presser member.

Preferably this mechanism comprises a lever mounted on the frame of themachine and having an arcual portion which provides contacting surface for a single roll carried by another lever mounted on the presser member, the construction and arrangement being such that the roll remains in contact with the arcual surface in all positions of the presser member and without any tendency to a binding action during movements of the latter. 7

A principal feature of the starting mechanism resides in the provision of a handle for the mechanism mounted on the presser member and so arranged as to remain substantially stationary in space during; the reciprocation of the presser member in a pressure applying operation, whereby the pulleys on the supporting post of the presser member;

Fig. 3 is a detail of the starting mechanism; and j Fig. 4: is a section of the presser member in front or the operating pulleys and showing the attachments ot the pulley bands to the presser member.

In the illustrative embodiment of the invention there are shown a work supporting bed 6 and a presser member 8 movable laterally over the work supporting bed into different operative positions with respect to the work on the bed. Mounted in bearings 10' and 12 of the frame 14: of the machine is a post 16 which supports the presser member 8 for rotation about the axis or the post.

Preferably, and as shown, the presser mem her 8 is fixedly secured to the post 16, and upon reciprocation of the latter vertically the presser member is caused to approach and recede from the work supporting bed in pressure applying operations upon work on the bed. Mounted in the frame or the machine is a shaft 18 operatively connected to the post 16 by means not shown but which may be according to the construct-ion disclosed in the patent to Arthur Bates, No. 921,503, granted May 11, 1909, said shaft carrying a power pulley 20, clutching mechanism being provided for connecting the shaft to the power pulley at the will of the operator, the said clutching means being preferably housed in a casing 22 and being of a well-known type of one-revolution clutch mechanism preferably, though not necessarily, like that shown in said patent. Startin means under the control of the op erator tor causing operation of the machine as desired comprises a lever pivoted on the frame of the machine and connected by a link to the clutch mechanism so that upon operation of the lever the clutch may be tripped and thuscause operative connection of the shaft and power pulley.

An improved form of starting means comprises a lever 2a pivoted at 28 to the upper part of the frame of the machine and having at its forward end an arcual portion 30 extending in front or the upper bearing 12. By this arrangement of the tripping lever the bearing 32 ot the presser member 8 may be made as deep as desired, since no part of the lever is interposed between the presser member and the bearing 12, the construction and arrangement differing in this respect from that shown in said patent to Bates. In other words, the bearing may be extended along the post 16 practically into contact with the lower surface of the frame bearing 12 when it is desired to make the presser member 8 especially heavy and give it a deep bearing on the post. In co-operation with the lever 24 there is provided a lever-clevice mounted on the presser member, the construction being such that the device on the presser member engages the upper surface only of the arcual portion 30 of the lever 2a,-

thus providing against any tendency of a binding action between the engaging portions as the presser member movesabout its axis oi": support. Preferably, the lever device on the presser member comprises two levers 3e and 36 mounted on pivot supports 38 and i0 respectively, the supports being vertically adjustable as indicated by set screws as provided for securing the supports in adjusted position. lhe arms a, a of the lever 3e are equal in length in the horizontal direction as also are the arms 6, b of the lever 36, it being immaterial whether or not the arm a is equal in length to the arm b. As shown, the arm Z) of lever 36 carries a roll it for engaging the upper surt'ace of the arcual portion 30 of the lever 2a. At the other end of the lever device, the arm a of the lever 54 carries a handle member l6 having shoulders or collar portions 48 for engaging the upper and lower surfaces of the end of the lever arm a. In order that the handle as may move laterally with respect to the lever 3d, the said lever is provided with a slot extending transversely ot' the end or the lever, the arrangement of the handle and elongated slot having a purpose which will be later pointed out in connection with means for moving the presser member laterally :t'rom and into position over the work supporting bed. i I

An intermeshing gear tooth connection is provided at 0 between the adjacent ends of the levers 34: and 36, and upon depression of the handle as, the lever device just described will operate through the roll at to depress the arcual portion 30 or the lever 2e and thus trip the clutch on the main shaft of the machine. After the clutch is tripped the presser member moves downwardly in a pressure applying operation carrying with it the pivots 38 and of the levers 3 s and 36. As the roll e4. cannot move downwardly with the presser member 8, the lever 36 swings about its pivot -10 causing the adjacent connected arms a and b of the levers 34; and 36 to move downwardly and the other arm a of lever to move upwardly oarrying the handle 4-6 upwardlyaway from the presser member .8 a distance equal to the amount that the presser member is depressed in its pressure applying movement.

In other words, the downward movement 7 operator, it being clear that the handle remains practically stationary in space during a complete reciprocation or the presser member. Another important advantage of the starting means resides in the construction by which no binding action takes place between any of its parts during movement of the presser member laterally over the work support or upon reciprocatory movement toward and from the work support.

In most of the presses as at pr" eat constructed, the presser member is moved laterally over the work supporting bed by force exerted directly by the operator. l /hen the presser member is particularly heavy and in other constructions also, it is desirable to provide power means for moving the presser member laterally over the bed thus lessening materially the labor involved in operating' a press of this kind. In the illustrated machine the power means for moving the presser member comprises connections with the power pulley on the main shaft oi the machine so constructed and arranged as to impart lateral movement to the presser member at he will or" the operator. In the construction shown, the pulley 20 is provided with a pulley 50 formed integrally therewith or securely attached thereto and about Which passes an endless cable 5 There are provided also pulleys and 56 mounted preferably on the post 16 and arranged to be driven constantly in opposite directions by means oi the cable 52. The upper run 58 or the cable 52 passes over an idler 60 and thence around the upper pulley 54 in a groove therein and from there to an idler pulley 6:2 mounted on the frame of the machine. The cable passes around this idler 62 and thence as the lower run 6d of the cable it passes around the lower pulley 56 in a groove therein and thence to and over an idler 66 to extend to and become continuous with the cable passingaround tl e pulley 50. In the construction shown, the idlers G0 and 66 are mounted upon a bracket 68 extending from the frame of the machine. the pulley 62 being mounted prelierably in a slidable bearing (not shown) on the frame 14 so that it may be adjusted to take up any slack in the cable 52. Upon tracing the course of the endless cable 52 it will. be seen that the upper pulley 5% turns in the opposite direction to the lower pulley 56. thus providing surfaces In ving in opposite directions to which the presser member may be operatively connected when it is desired to move the presser member into and out of position over the work support-- ing bed. In the illustrative construction, the connections between the presser member and the pulleys 54; and 56 comprise a lever 70 pivotally mounted at 72 upon a. web 74 in. the presser member 8. the free end of the lever receiving for vertical sliding moveit will be seen that when the lcv.

tending vertically across said end so provide an up ier and a lower pin or to which are connected means passing around the described moving surfaces and attached to the presser member for selectively connecting the presser member to 1; surfaces, the said means comprising pre. 75 ably relatively ide bands and 82, upper band 80 passing a: member 84.: fixedly attached with the upper pulley or w band 82 passes arounc. a C()ll'SP0llLll.i;- pulley member 86 similarly securer. pulley 56. One end of the limo cured to a pin or belt 558 fire ell" the nresser member .3 while the other end of the Seine band is wrapped around or otherwise secured to the upper pin or arm 78 horizontally alined with the bolt 88 and located on the lever 70. The lower bane S25 is similarly secured to the press-er member and to the lever by having); one end secured 90 to a pin or bolt on the press", oien'ihei' audits other end o the lower pin arm 79 horizontally alined with bolt 89 and can ried on the lever 70, the end of the band 82 :ured to the press-er member being attached in a lower plane and laterally oi the point of attachment of the upper bar or the presser member, as will be clear an inspection of Figs. 2 onl 4- o? the ings.

It will he observed that the handle 46 is moved in the directioi'i that it desired to more the presser member and that by this movement or": the lever the proper pulley is connected to mov the presser member in the direction the hand moves in actuating the lever 70. New. it will be seen that the elongate. slot in the outer end of the lever 3 is for the purpose of permitting lateral movement of the lever 70, to which the handle 46 connected. while retaining: operative connection li ctween the handle 46 and the lever E l: so that at the end of the lateral movement of the lever 70, said handle may be depressed to operate the lever 34: and thus cause a tri ping of the clutch on the main shaft of machine, by which a pressure applying opration is *oduced.

ln the operation of the machine, work is placed upon the work. supporting bed 6 and the presser member is moved to one side to permit light to reach the work and to provide space for the manipulation oi the work and or the die in locating the latter in de sired relation to the work. When the work is properly arranged, the presser member is swung to operative position, the operator grasping the handle as and moving it in the direction that he desires the presser member to move whe eupou the power means is connected to the presser member to assist the operator in moving the prcsser member, the construction and arrangement being such that the presscr member follows the hand of the operator with the very minimum of etfort on his part. As the presser member is approaching the die and without waiting until it is directly over the die, the machine is tripped by depressing the handle it; whereupon a pressure applying operation takes place, thus forcing the die through the work. The machine provided with a brake mechanism indicated 90 and di closed in the patent to Eaton No. l,00 l,757, granted October 3, 1911, which makes it possible to trip the clutch while the presser member is still moving laterally, as described, the brake operating to stop the lateral movement just as the presser member is about to strike the die, thus preventing the striking of a glancing blow. It should be pointed out that as the handle 46 is depressed its movement laterally is terminated, while the presser member continues to move under its acquired momentum with the result that it almost instantly disconnects itself from the pulley which was moving it. Jitter the pressure applying operation, the presser member is swung away from over the die by pressing laterally on the handle 46 in whichever direction it is desired that the presser member shall move, whereupon the proper pulley is connected to move the presser member. If desired the presser member may be moved very rapidly away from over the die by pressing firmly in a lateral direction on the handle L6, in which case it becomes necessary to check the'lateral movement of the presser member when it has reached the position selected by moving the handle 46 in the opposite direction, whereupon the other pulley is at once applied to the presser member as a brake device to bring it to rest.
