COMPRESSING-MAGHINE.
'10 all whom it may concern:
Be it known that I, THOMAS LUND, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain Improvements in Compressing-l/Iaehines, 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 tact between these parts in the attaching operation.
An important object of the present invention is to provide a compressing machine by which heel lifts may be compressed without the formation of projections such as would interfere with the proper attachment of the lifts to heels.
To this end an important feature of the invention consists in the combination with means for molding the peripheral surface of a heel blank of a member for molding one face of the blank arranged with its surface overlapping said means. lVith this arrangement, if a fin is formed at the junction of the peripheral surface of a top lift with said face, it will not project outwardly from said face normally thereto but will extend in a plane parallel to the face and will thus not interfere with bringing the top lift into close contact with the face of the heel.
It will be understood that by the term peripheral surface employed herein it is meant to include those surfaces upon a heelblank which extend in the direction of its height. The remaining surfaces which, in the case of a top lift, are fiat will be referred to herein as the faces of the blank.
A further object of the invention is to provide a compressing machine wherein a heel-blank may be placed in operative re- Specification of Letters Patent.

lation to the dies with accuracy. It is also an object of the invention to provide a compressing machine wherein a compressed blank may be quickly and accurately discharged from the machine.
To these ends an important feature of the invention consists in a machine for compressing heel-blanks so constructed and arranged that a blank to be compressed is carried into operative relation to the dies upon a member which forms the bottom of the mold cavity. According to this feature, a blank to be compressed is moved into position between the side dies which mold the sides of the blank in a single horizontal movement in the plane of the side dies. In order to permit the insertion of the blank in this way, a breast die for molding the breast of a blank is arranged to be moved vertically relatively to the side dies to allow the passage of the blank beneath it. After the blank has been moved beyond the inner face of the' breast die the breast die is lowered relatively to the side dies into operative relation thereto. After the compression of a blank, the member forming the bottom of the mold cavity is withdrawn, allowing the compressed blank to fall by gravity into a chamber beneath the dies from which it is ejected in the next advance of said member.
In the particular construction herein described, the member forming the bottom of the mold cavity, hereinafter called a bedplate, and the dies which mold the peripheral surface of a blank are mounted upon a vertically reciprocating head. The movement of the bed-plate and said dies is automatically efiected by the movement of the head. In the present construction, a device for molding the top surface of a blank, hereinafter termed a presser, is also mount-- ed upon the vertically moving head. The presser is yieldingly supported upon the head in a position permitting the free entrance of a blank into the mold cavity. A stationary abutment upon the machine is provided in position to be engaged by the presser in the rise of the head to force the presser upon the blank and subject it to vertical pressure.
The dies herein shown and described are formed to produce a top lift of the particular contour of that covered by U. S. Letters Patent 890,43 granted June 9, 1908, to
B. F. Mayo. In the top lift disclosed in this patent the edge of the lift along the sides and curved end is in part normal to the tread face of the lift and in part has an angular relation thereto. It is desirable that the straight portion or that portion normal to the tread face shall be of approximately the same width regardless of the thickness of the top lift. ()n this account where compressed top lifts vary in thickness, the beveled portion of the lifts or that portion which is oblique to the tread face is allowed to vary in width. The side dies herein shown and described are so formed that they may be used with blanks of different thicknesses. To this end said dies are provided with beveled portions of different widths at different points to be used with blanks of different thicknesses. In the arrangement shown, the side dies are so constructed that they may be used either side up, and at top and bottom they are provided with beveled portions of different widths.
The construction and arrangement of the parts in the present machine is such that the mold cavity flares downwardly, the blanks being compressed in the machine with their tread faces uppermost. The presser which engages the tread face of a blank has contact in the compressing operation with the straight portion of the walls of the side dies above the beveled portion at the bottom of said dies. ith this arrangement it is not necessary that the movement of the presser toward the bed-plate shall, under all circumstances, be to a certain limit and the present machine is accordingly provided with means for varying the limit of movement of the presser toward the bedplate. This feature is of advantage in securing the application to a blank of the desired amount of pressure.
Other features of the invention, the advantages of which will be hereinafter mentioned or which will be apparent to one skilled in the art will be hereinafter described and referred to in the appended claims.
Tn the drawings,-Figure 1 is a view in perspective of the more important parts of a machine constituting one embodiment of the present invention; Fig. 2 is a vertical sectional view of the parts shown in Fig. 1, taken upon a plane extending centrally of the mold cavity; Fig. 3 is a view in perspective of the side dies and the presser carrying block mounted thereupon; Fig. 4tis a view in perspective of a side die; Fig. is a view in perspective of a stationary abutment with which the presser carrying block has engagement in the operation of the machine; Fig. 6 is a view similar to Fig. 2, illustrating a different position of the parts wherein the mold is closed upon a heelblank; and Fig. 7 is a perspective view of a compressed top lift.
Referring to the drawings, the reference nume *al 2 indicates a. vertically moving head to which a reciprocatory movement is imparted by suitable mechanism, such as is shown for example in United States Letters Patent, T7651), Dec. 6, 1901. The reference numeral el indicates the upper member of the toggle of said patent which imparts vertical movement to the head 2. Mounted upon the upper sine of the head 2 are slides 6 upon which are mounted side dies 8. The slides 6 are moved horizontally toward and from each other upon the head 2 by links 10 pivotally connected to said slides and also pivoted to the frame of the machine, as in the machine shown in the Letters Patent referred to. lVithin each of the slides 6 at its inner edge and adjacent the forward end thereof is mounted a vertical slide 12. Each vertical slide 12 has a horizontal member ll of T shape in cross-section formed integrally therewith, having engagement with a groove of corresponding shape in the side of a breast die carrying block 16. As will appear from Fig. 1 the members 11 extend obliquely from the front toward the sides of the machine. Each of the vertical slides 12 is provided with an oblique surface 18 havingengagement with an end of the block 16 of corresponding obliquity. It will be seen from Fig. 1 that in the approaching movement of the side die slides 6 the breast die carrying block 16 will be forced toward the rear of the machine by the inclined surfaces 18. This movement of the block 16 is permitted by the connection between said block and the vertical slides 12 upon which the block is mounted.
Upon the rear side of the block 16 at its lower edge is mounted a breast die 20, hav ing a dovetail entering a vertical groove 21 in said block. The breast die is held in position upon the block 16 by a spring-pressed pin 22 mounted in the block 16 and entering a socket in the breast die. As shown the rear or acting surface of the breast die is vertical and. of flat contour as indicated in Fig. 2.
Above the side dies 8 arranged a presser carrying block 2 1 in which are mounted yielding pins 26, the lower ends of which bear upon the upper surface of the side dies 8 as shown in Fig. 3, thus sustaining said block yieldingly. The forward end of the presser carrying block 2% is connected with the breast die carrying block 16 by a dovetail entering the groove 21 as will appear from Figs. 1. 2 and 3. A screw 26 mounted in the breast. die carrying block 16 enters a. groove 30 in the forward face of the presser carrying block 24 and limits upward movement of the presser carrying block 2st relatively to the breastdie carrying block 16.
A presser 32 is supported upon the lower side of the presser carrying block 24 and as shown in Fig. 2 is provided with flanges upon opposite sides entering grooves 34 formed in the lower part of the block 24. The presser 32 is placed in position upon its supporting block 24 by sliding it in the grooves 34 from the rear of said block. A spring-pressed locking pin 36 is mounted upon the presser carrying block 24 in position to enter a socket in the presser in the operative position of the latter and retain said presser from rearward movement in the grooves 34.
Above the movable head 2 is arranged an abutment 38 in stationary position upon the frame of the machine. In the rise of the head 2 the presser carrying block 24 engages the abutment38 and is forced toward the bottom of the mold cavity. The abutment 38 is supported upon a base 40 and is arranged for vertical adjustment upon said base. To secure its vertical adjustment there is provided a wedge 42, the upper side of which is provided with flanges 43 engaging horizontal grooves in the base 40 and the lower side of which is provided with inclined flanges 44 engaging similarly inclined grooves in the abutment 38. To insure that the abutment 38 will at all times have the same position with reference to the front and rear of the machine, the base 40 is provided with depending lugs 48 between which lies a shoulder 50 extending laterally from the abutment 38. As will be seen from Fig. 5 this maintains the abutment 38 in a predetermined position relatively to the front and rear of the base 40. The base 40 may be secured upon the frame of the machine in any suitable way, as by means of the screws 52, shown in Fig. 1.
Mounted upon the head 2 for sliding movement in grooves 54 longitudinally of the mold cavity is a bed-plate 56. The bedplate 56 carries a face plate 58 which, in the operative position of the bed-plate, forms the bottom of the mold cavity.
As shown in Fig. 1, the face plate 58 is provided with a corrugated portion to corrugate the inner part of the lower surface of the top lift being compressed. Movement is imparted to the bed-plate 56 by a cam lever 60 which is pivoted at 62 upon a bracket 64 extending forwardly from the head 2, which bracket supports the bedplate in the forward position of the latter. The cam lever 60 is provided with a cam slot 66 of the shape shown in Fig. 2, this slot being entered by a cam roll 68 journaled 011 a fixed pivot upon the frame of the machine. The cam lever 60 is connected to the bed plate by a link 70 which has yielding engagement, through a spring 72, with a rotatable member 74 secured to the bed-plate. It will be seen that in the upward movement of the head 2 the upper end of the cam lever 60 will be swung to the right in Fig; 2 by the cam roll 68 and the bed-plate will be advanced toward the rear of the machine into operative position. The movement of the bed-plate toward the rear of the machine is limited by an adjustable set screw 76 engaging a stop surface 7 8 formed upon the bracket 64. As will be apparent from Fig. 2, the spring 72 permits variation in the limit of rearward movement of the bedplate, although the actuating mechanism for said bed-plate has a stroke which is fixed in amount.
Upon the upper surface of the bed-plate is arranged a finger 80 the forward end of which constitutes a gage for the breast edge of the top lift. As shown, the finger80 is pivoted at 82 upon the bed-plate and is supported at its front end by a spring 84 which cooperates with a screw 86 in the rear end of the finger to maintain the finger normally in the position shown in Fig. 2. As will appear from this figure, the screw 86 limits upward movement of the front end of the finger by engagement with the rear end of the bed-plate. By adjusting the screw 86 the normal position of the finger 80 may be varied.
Supported above the bed-plate upon the bracket 64 are gages 88 which rest loosely at their front ends upon the upper surface of the bed-plate and at their rear ends are supported upon a screw 90, arranged above the bed-plate and journaled in the bracket 64. The gages 88 have threaded engagement with the screw 90 and opposite end portions of said screw are oppositely threaded so that by turning the screw the gages are adjusted equally in opposite directions. The gages 88 form a guideway for the top lift and prevent its displacement laterally of the bed-plate in the movement of the bed-plate toward its operative position. A cover 91 is supported upon the bracket 64 in position to cover the moving parts upon the front end of said bracket.
The vertical slides 12 upon which is mounted the breast die carrying block 16 are connected at their lower ends to rods 92 which enter vertical guideways in the fixed frame of the machine. Each rod 92 is provided with a collar 94 adjustable longitudinally of the rod and held in fixed position by a set screw 96. The lower end of each rod is provided with an adjustable nut 98 between which and a portion of the frame of the machine is arranged a spring 100 coiled about the rod 92. As will be apparent from Fig. 1, in the rise of the head 2 each rod 92 is pressed downwardly by its spring 100 and the breast die carrying block 16 is thus lowered upon the head 2. In the descent of the head 2 the collars 94 upon the rods 92 come into engagement with the fixed frame of the machine and arrest downward movement of said rods, thus raising the breast die carrying block 16 upon the head 2.
By referring to Fig. L, it will be seen that the side die 8 shown therein is provided with two beveled surfaces 102 and 101, the latter of which is of greater width than the former. The two side dies 8 are of identical construction and are so connected to the slides 6 that they may be inverted in position and interchanged with each other in order that either of the surfaces 102 and 104 may be used in compressing a blank.
Each side die 8 has engagement upon two sides with the walls of its slide 0. Rigidly secured upon the slide 6 above the side die is an angular member 100. A removable pin 108 extends through the member 106 and into a bore extending through a side die at one corner. It will be seen that by removing the pin 108 a side die 8 may be disconnected from its slide 6, and may then be connected to the opposite slide in an inverted position.
In the operation of the machine shown, it will be observed that at the lowermost position of the head 2 the breast die 20 is in the raised position upon said head illustrated in Fig. 2. A lift 110 to be compressed having been placed upon the bed-plate 56 with its breast edge against the flat end of the finger 80, in the forward movement of the bedplate the lift will be advanced beneath the breast die and beneath the presser 32 into position between the side dies 8. In the greater portion of its forward movement it is guided by the gages 88. The movement of the bed-plate toward the rear of the machine occurs during the first part of the upward movement of the head. At the same time the breast die 20 is lowered upon the head through the action of the springs 100. The movement of these parts is so timed that the top lift passes beyond the inner face of the breast die before the latter descends to the level of the upper face of the lift. The cam slot 66 in the cam lever 60 is so formed, as indicated in Figs. 2 and 6, that immediately after the bed-plate reaches the limit of its movement toward the rear of the machine it is retracted a slight amount. One advantage of this feature is that such compression of the spring "72 as occurs in the movement of the bed-plate toward the rear of the machine is relieved before the bedplate is given its final position. The position of the latter is thus positively controlled. It will be observed that the presser 32 is in close relation to the upper face of the lift as it is moved between the side dies.
In the upward movement of the head the side dies 8 are moved together and simultaneously with such movement the breast die is moved toward the rear of the machine. The side dies and breast die thus subject assess the blank to lateral pressure. After these dies have closed upon the blank, the further rise of the head brings the presser carrying block 24 into contact with the abutment 38, forcing the presser toward the bed-plate and subjecting the blank to vertical pressure. The presser in its movement toward the bedplate has contact with the straight portion of the side dies above the bevel at the bottom of said dies. The presser moves to a point short of the junction of the straight portion and the beveled portion of said dies, thus leaving the edge of the blank adjacent to the tread surface normal to said tread surface.
In the descent of the head, the presser 32 is raised from contact with the blank by means of the spring-pressed pins 26 and the side dies and breast die release the compressed blank. In the further descent of the head the bed-plate is moved toward the front of the machine and the compressed blank falls by gravity into the chamber in which said bed-plate is received. The blank remains in this chamber until the next movement of the bed-plate toward the rear of the machine when it is pushed by the bed-plate from the chamber into a suitably arranged discharge trough.
It will be observed that in the use of the present machine if a fin is formed at the junction of the peripheral surface of a lift with the lower face of the lift it will lie in a plane parallel to said face and will not project outwardly from said face. This will be the case regardless of the amount of wear which the parts of the mold may receive. It will be understood that the presence of a fin extending outwardly from the opposite face of the lift is not particularly objectionable, as it does not interfere with the attachment of a lift and will be subsequently removed in the heel trimming or heel securing operations. The presence of a tin projecting outwardly from the inner face of a top lift in such a direction as to prevent close contact of the lift with the face of the heel in the attaching operation produces several injurious results; for example, it causes a crack to come into view after the trimming and scouring operations and it may also prevent a top lift from being attached evenly, causing the lift to lie in a non-parallel relation to the face of the heel.
It will be seen that in the present machine the top lift after being placed by the operator upon the feed slide is moved into operative relation to the dies by a single movement. In this respect the machine is simpler in construction and operation than machines wherein a feed slide places a lift upon the top of a vertically movable presser plate forming the bottom of the mold cavity and in which the presser plate thereafter descends to carry the top lift into operative position in the mold cavity.
