Be it known that 1, ORRELL Asa-Iron, a citizen of the United States, residing at; Swampscott, in the county of Essex and State of Massachusetts, haveinventedcer tain Improvements in Machines forUse in the Manufacture of Boots and Sl1oes,9of which the following description, in connec-i tion with the accompanying drawings, is a specification, like reference characters on the drawings indicatinglike parts in 1. the several figures. I

This invention relates to machines for use in the manufacture of boots and shoes and particularly to shoe shaping machines.

The invention is herein shown as embodied in a machine of the type disclosed in United States Letters Patent No. 1,030,837,

granted June 25, 1912. This type of machine comprises a. rotary beater which includes a very rapidly rotated carrier or hub having annular end disks, between which disks extend stems or rods arranged around the periphery of the carrier and supporting an annular series of beating elements which strike a very rapid succession of light blows. The beating elementsare arranged to be held out radially from the carrier by centrifugal force in normal operative position while the beater is rotating, and to yield inwardly when they strike the work. Machines of this type are employed with great success in poundingnp the overlasted marginal portions; of shoe upper at the sides of the heel seat and, in some classes of work, along the sides of the shank portion and forepart of the shoe bottom.

An object of the present invention is to: provide for a machine of the type above outlined new and improved beating ele ments, the advantages of which include especial adaptability for levelingthe SUP-1 face bein beaten.

Accordmgly, a feature of theinventiolr consists in the provision for a machine of} the type above mentioned of beating ele ments which 00111131186111 a preferred form resilient coils somewhat loosely encircling the above mentloned rods.

These resilientj coils may be supported by the carrier at their ends, but be free to respond to the action of centrifugal force and to yield against that force under pressure of'ythe work at all pointsintermediate between;

their ends. I lksherein shown forthe purpose of illustration, each of these coils consists of a single cont nuous helical spring,

each ofthesesprings being closelywound tions, the joints between which are oblique to the direction of rotation so that the tendency of the convolutions to leave ridges on the surface of the work is further reduced. Also, by oppositely winding alternate coils the saidjoints are reversely inc-lined and the oonvolutions of one coil wipe or beat out any ridges left by the preceding coil. It is to be noted that each convolutionof a coil presents a heating element and that these possessed by the described construction, when .1 its ends are; supported on the rods,

disconnected beating elements is that the rattling sound, which accompanies the startingzof a beater shaving loose beating elements whichall hang down. by gravity when the heater is at rest, is avoided.

These and other features and advantages ofthe present invention, including certain details of constructionand combinations of parts, will be fully set forthand explained in the following detaileddescription of so much of a machine embodying a preferred form of the HIVQHUODI as 1s necessary for a thennb-e clearly defined in the appended claims.

a rigid bar would be. Another advantage over a longitudinal series of separate and p complete understanding thereof, and will Rcferringto the drawings: Figure "1 is an I angular perspective in elevation of so much f of the machine as is concerned with the present invention; Fig. 2 is a front view showing in elevation the beater carrier and the beating elements supported thereby; Fig. 3 is a plan View partly in section show ing a beating element in operative relation to an edge of the heel seat of a shoe; Fig. 1 is an end view in elevation, showing in detail the operative relation between the beater, the shoe resting and guiding means and the work; Fig. 5 is a front View in elevation showing in detail the relation of the shoe to the beater and the work resting and guiding means in the first position of the shoe; Fig. 6 is a view similar to Fig. 5, showing the last or extreme position of the shoe, with relation to the beater and the shoe resting and guiding means.

Bearings 2 on the frame of the machine support a shaft 1, upon which is mounted a hub or carrier having end disks or flanges 6. The end disks 6 are connected by rods or stems 8 which support an annular series of beating elements 10. The beating elements 10, in accordance with the present invention, comprise resilient coils loosely encircling their respective pivot rods 8. As shown, each of the coils 10 consists of a continuous helical spring restrained at its ends by collars 12, but entirely free at points intermediate between its ends to be moved radially with relation to the axis of the carrier. The beating elements are, as shown in F 1, arranged about the periphery of the carrier and thus constitute, taken collectively, a ribbed cylindrical beating roll normally concentric with the axis of rotation of its carrier, each of the beating elements being, however, mounted eccentrically with relation to the said axis. During the rotation of the roll, the said heating members will be pressed out radially under the action of centrifugal force in normal operative position, the springs at points between their ends bulging outward slightly beyond the periphery of the carrier disks as illustrated in dotted lines in Fig. 2. Uuder pressure of the work, however, the portions of the springs intermediate between their ends, owing to their said mounting, and also by reason of their resiliency, will yield inwardly and radially against the said force (Fig. 3), each of the springs yielding independently of any of the other springs. At the same time the helical springs are capable of being bent laterally or rearwardly, thus yielding in a circumferential direction independently of their inward yielding.

As illustrated clearly in Fig. 2, the coils or springs which constitute the beating members are preferably closely wound. This obviates to a large extent danger of marking or lining the stock, particularly if, as in some uses, the beater is employed for treating the edge portion of the side of a shoe. Preferably, too, and as best illustrated in Fig. 2, the beating coils are al ternately reversely'wound so that each coil is oppositely wound with respect to itsneighbors. This arrangement produces a very thorough and efficient treatment of the work and, at the same time, tends to aid materially in preventing lining of the stock, the action of one member obliterating marks made by the oppositely directed action of the preceding member.

As shown in Fig. 1, the above described beater may advantageously be employed in conjunction with the plate 14 which extends into close proximity to the outermost position of the beating members, and is adapted to engage the side of the shoe. This plate 14: for resting the shoe cooperates with the beating members in-shaping the side of the shoe at and adjacent to the edge of the last by reason of the pressure of the shoe against it. The said plate may be stationary or conveniently, to facilitate its cooperative action, it may be actuated by suitable means to beat or rub the upper.

For beating the sides and the bottom of the heel portion of the shoe and also the sides of the forepart of the shoe bottom, the shoe may be rested on a horizontal member 16, as illustrated in Figs. 5 and 6. In the common use of the machine for heel seat beating, the said member 16 will thus serve as a rest for one side of the heel portion of the shoe at a time for presenting the shoe to the beater for treatment of the heel seat at the other side, as clearly shown in Fig. 4. Preferably, and as shown, the upper face of the member 16 is convexly rounded to facilitate turning the shoe from the first position shown in Fig. 5 to the extreme position shown in Fig. 6, and to insure that during this turning the successive portions presented to the beater will be in the same horizontal plane, thus compensating for the lift of the shoe.

As shown in Fig.1, the member 16 may have associated with it a vertical guide or rest which consists of a relatively thin plate 18, having a horizontal extension 20 supported upon a flat part 22, fixed to an uprightpost 24L which is adjustably secured in a bracket on the machine frame by a set screw. The horizontal rest 16 caps the extension 20 of the vertical guide 18 and a set screw 23 passing through a hole in the part 22 and through a somewhat elongated transverse slot in the extension 20, has screw threaded engagement with the rest 16, thereby binding the said parts together. By reason of the elongated transverse slot in the extension 20, the vertical guide 18 can, if desired, be adjusted toward or from the beater.

The end portions of the guide 18 form at each lateral side of the rest 16 vertical stops by the rest gar en) 'de The member 18 also constitutes a guard to prevent the beater from en'- gaging and forcing toward the edgeof the last bottom the upper on the lower side of the heel seat While the heater is forcing inwardly the upper onthe upper side of the heel seat. If it is desired to extendthe field of operation to the shank regiono'f the shoe, the vertical member instead of engaging a rear side lasting tack. may be interposed between the heater and the. side lasting tacks;

onthe lower side of the shank, and by such interposition prevent these tacks from being disturbed during treatment of the shank at the upper side. Preferably, the upper cor- :ner portions ofthe vertical rest 18 are rounded similarly (Fig. 1) to the upperface of the member 16. As a result, for manipulating the shoe from the first position shown in Fig, 5 to the lastor extreme position shown in Fig. 6, the shoe may be rocked about the rest 16 without disturbing the guiding engagement of the member 18 with the rear side lasting tack 25 which WlllSllClG along the edge of the member 18 as. the

shoe is turned.

In order to facilitate? tippingrtheishoe transversely of its longitudinal axis, cans.

ing the side of the heel seat to be treated: to bear against the beater with the required pressure and at the desired angle, the upper and end edge portions of the vertical memher 18 may be beveled as illustrated Fig. 1.

The novel features of thenabove-described work resting and guiding means together with the combination of said means with the beater are not herein claimed since they soonstitute the subject matter of a co-pending divisional application, maturing in United States Letters Patent No. 1,032,356, dated July9, 1912, a

Having thus fully described one illustrative embodiment of this inventionpwhat I claim as new and desire to secure by Letters.
