Be it known that we, FREDERIC E. BER- TRAND and PEARL J. WENTWORTH, citizens of the United States, residing at Lynn,iin the county. of Essex and Commonwealth of and Newport, in the county of Campbell and State of Kentucky, respec- Improvements in Shoe-Beating Machines; and we do be a full, clear, the invention, y skilled in the art` to which it make and use the same.

and exact description of This invention rel tes to beating machines I for beating out the bottom portions of shoes.

1n the manufacture'l of welted shoesthe;

featherA of the insole is often bent or turned to a considerable degree away froml the plane of the body of the insole after the inseam is sewn. The feather pressing against bove the inseam gives the proper bulge or overhang to the upper, and determines to a great degree the shape of the shoe, andthe undue bending ofv the feather away from the plane of the body Y of the insole gives the shoe .an irregular and n shoe beating scription. A

unfinished appearance.

The primary object `of th'e present inven-v tion is to produce an improved and efficient machine by which the welt and the feather of the insole may be beaten out and set substantially in the plane ofthe body of theinsole'quickly and easily in one operation. v y l 1,

ithy -this object in :view the invention consists in the novel and improved constructions, arrangements and combinations o parts hereinafter described and pointed out the advantages of which will be obvious to those skilled in the art. f

Fig. 6 is a sectional view taken substantially on the line 66 of Fig. 3.

rlhe machine illustrated in the drawings is provided with a welt support 2 shaped to enter the crease between the welt and upper of a lasted shoe and support'the welt upon its upper surface, and with la feather support or table 11 havingits uppersurface substantially parallel with the upper surface of the welt support `and adapted to engage the inner face of the .marginal portion of the insole to support the feather .in sub'- stantially the plane of the sole. The machine is also provided Vwitha hammer 6 arranged to extend over the welt and the marginal portion of the insole when the shoe isplaced in Operating position in the machine.

The beating hammer 6 is fixed tor the lower end of a hammer rod 8 mounted for vertical reciprocation in guides in the for- 10'and 12 formed on the frame of the machine. The hammer rodis reciprocated by the movement of sleeve 111 mounted on thev hammer rod and connected by a link .orpitman 16 with a crank 18 on the hammer operating shaft 2O mounted in a suitablebearing in the vframe. In order to cushion the blows delivered by the hammer, a coiled spring 22 surrounding the Ahammer is interposed between the sleeve 111 and a collar or nut 24C on the hammer f-` rod. The downward movement of the' ham.

mer rod in the sleeve 1 4 islimited bythe engagementof the upper end of the sleeve with a collar or nut 26 on the rod.

he'welt support 2 *consists` of a rotary table mounted on the forward end of a bar 28 secured to a pivoted carrierBO.` rlhe carrier 30 is pivoted upon a shaft 32, and rests at its rear end against the cam face 34. of an abutment 36 pivoted on the shaft 38. The abutment 36 is normally held in forwardv position as illustrated in dotted lines of a coiled spring 10 secured at its'endsrcspectivelv to the carrier 30 and to the abutment.` The cam face 34 Patented Feb. 24:, 1920. i' Application filed February 26, 1916. SerialNo. 80,612f i v body of the inioo . and Vmay then turned .ends engaging is formed on a gradually increasing radius from the rear to the forward portionof the abutment, so that by swinging the abutt ment y'from theV position shownin dottedA lines lreadwardly to the position lshown in full lines in Figzl the Welt support will` be raised. The raising of the welt support increases the pressure of the hammer on the .,welt, and .enables the refractory portions of the welt to be beaten out more readily.

Ihe abutment 36 is swung in a direction to raise the welt support by means of a treadle (not shown) connected with the abutment by means ofV a treadle rod 42. The move- .ment'of the abutment in a direction to raise the welt support is limited by the engage,- ment ofgan adjustable abutment screw V44 mounted in an arm 44 formed on the abutment 34 with a projection 46 on'the frame.

The feather support 4 is mounted on the upper end of the rotatable horn/ t8 similar to the horn employed on certain classes of shoe sewing machines. The horn is provided with a cylindrical shank 50 which is adapted to be clamped in a bore in the clamping arm 52 of the horn carrier 54 by means of a clamping bolt 56. y looseningr the clamping bolt the horn is arm and clamped in adjusted position. The horn carrier 54 is pivoted upon the vertical shaft 58 so that the horn may be turned as the different parts of the welt and the Inargin of the insole are presented to the action of the Ibeating hammer. Y 'The horn vcarrier isl held on the shaft 58 by means of a ca plate 60-secured to the upper end of the shaft'. In order to enable the shoe to be placedy in position with the horn within the shoe and thek feather support engaging the lower face of the margin ofthe insole and the welt support underlying the welt, the horn is mounted upon a horizontal axis to swing forwardly away from the welt support. The shaft preferably formed integral with a hanger 62 mounted on the shaft 64car1fied by the forwardly projecting arms 66 on the frame of the machine. The l in operating position by spring controlled mechanism acting on theV hanger 62. The hanger 62 is formed with a forwardly 4projecting arm 68 which engages in the loop end of a U-shaped wire 70 passing through the compression spring 72, and having its out-turned ends engaging one end of the spring. A similar U-shaped wire 74 passing through the coiled spring has its outthe opposite end of and receives in its loop end a pin 76 mounted at the end of a yoke shaped lever 78, the arms of which are fixed to trunnions 80mounted to turn in bearings in the forwardly projecting varm 82 on the frame. A gear 'segment 84 is yfixed to one of Y hanger.

unclamped be v adjusted vertically in the 58 1s carried by and` iorn is normally held and has its teeth in mesh a rack bar 86 attached to e hanger 62. The parts are constructed andv arranged so Lthat when the horn is in its normal or operatingrposition the connections between the'arm -68"and thepin 76 lie above the axis of the lever78, andthe coiled spring 72, through its action directly upon the hanger 62 and through its tendency to turn the lever 7 8,V tends to swing the hanger 62 rearwardly. The rearward swinging movement of the hanger is limited by t ment screw 88 threaded into the arm 90 on the frame with an abutment 92 on the The spring 72 during the opera#v tion of the machine constantly? tends ,to swing the hanger toward the rear of the machine, and thus keeps the' horn in operating position. The yieldingofthe sprin 72 allows the feather support to yield relathe'trunnions 80, with the teeth of e engagement of any adjustable a`but`v tively to the welt support to accommodate Y, i

different thicknesses of upper material -be` tween the two supports. j

hen a shoe Vis to be removed from the horn, or a shoe is to be placed in position on the horn, the horn is swung forwardly the arm 68 and thel pin 76 cross the axis of the lever L78, 72 is compressed, and the swinging movement of the arm takes place against the tension of the spring. After these connections pass the axis of the lever k78 the spring tends to turn the lever in Ya direction to swing the hanger l62, forwardly on the shaft 64. After a shoe has been placed on the horn the operator swings'the horn upwardly and rearwardly toward its operatrst part of this move` ment takes place against the tension of the spring 72, butxafterthe connections between the arm 68 and the pin 76 pass the axis of the lever .78, the .spring throws thehorn rearwardly into operating position.

tially coincident with the axis of the horn, i.

mec ing the feather support in a substantially unvaried angular position during the turning movements imparted to the hornas the point ofoperation is transferred about the shoe, to.k keep of the feather support in unvaried relation to the welt support and the beating hammer throughout the' 'beating operation. The

hanism is provided for maintain-Y the feather engaging margin l ,a bevel gear feather support is fixed to the upperl end of a shaft 94 journaled in the upper end of the horn. `A bevel gear lower end of the bevel gear 98 mounted to turn in the upper end of the horn. A second bevel gear 100 is fixed to the bevel gear 98 and meshes with a bevel gear 104 mounted on the upper end of a shaft 106 journaled in the horn. `This shaft carries at 108 meshing with a bevel gear 110 mounted on one end of a shaft 112 journaled in the horn, to the other end of which is fixed 116 mounted on the upper end of the vertical shaft 118 journaled in the cylindrical shank of the horn. To the lower end of this vertical shaft is fixed a spur gear 120 meshing with a small spur gear 122 journaled on the pin 124 secured in the horn carrier 54, which gear in Vturn meshes with a stationary spur gear tionary shaft 58 upon which the horn carrier turns. The series of gears above described intermediate the feather support 4 and the stationary gear 126 are so proportioned that the feather support 4 will be kept in a stationary position during the ro-.

tary movements of the horn. The result is that the marginal portion of the feather support having a curved edge of large radius is maintained in position opposite the welt support and beneath the beating hammer as the horn is rotated in presentlnir the different portions of the welt and'insoe to the action of the hammer. v
