' SOLE-ROLLING MACHINE.

Specification of Letters Patent.

Patented July '7, 1914..

Application filed July 2, 1908. Se-'rial No. 441,665.

To all 'whom it may concern Be it known that I, LE BARON C. COLT, of Bristol, in the county of Bristol and State of Rhode Island, have invented certain new and useful Improvements in Sole-Rolling Machines; and I do 4hereby declare the following specification, taken in connection with the accompanying drawings, forming a part of the same, to he a. Jfull, clear, and exact description thereof.

The invention relates to a machine which is more particularly adapted for use in connection with the manufacture of rubber-shoes or shoes composed of rubber and fabric. In the manufacture of suchshoes the several operations commonly performed after the shoe has been lasted consist in first applying what is known as the rag-filling sole to till the space between the in-turned edges vof the lasted upper; then applying cement to the shoe along the edges thereof; then applying the toe-tip, the heeletip and the foxing; then applying what is known as a cloth-filling sole to till the space between the in-turned edges of the foxing; and finally applying the out-sole;

In applying the rag-filling sole, the clothilling sole and the out-sole it is required in each case that the sole when applied shall lbe rolled into firm and close contact with the part immediately beneath the same. Heretofore the'several operations` above set forth, including the rolling of the sole, have been performed entirely by hand, the rolling .operation being performed by the operator by means otl a hand-roller.

The object of the present invention is to provide `a machine or apparatus which will serve to autonlatically effect the requisite rolling ot' the sole upon the lasted shoe, and thereby dispense with the operation of handrolling.

To that end the invention consists primarily in the combination, with a traveling carrieradapted to receive a lasted shoe, of a pressure-roller arranged and adapted to act upon the lasted shoe and roll the s ole thereon assaid lasted shoe is carried by said movable bed past said pressure-roller.

The invention further consists in the combinatiom'with a pressure-roller, of a traveling carrier adapted to receive a series of lasted shoes and carry the same successively past said pressure-roller, whereby, While a sole is being rolled upon one of saidy lasted shoes, another lasted shoe with a sole applied thereto may be placed in position on the traveling carrier in advance of the pres surero1ler.

The invention further consists in certain combinations and arrangements of parts to be hereinafter described and claimed.

Referring to the drawings, Figure 1 is a side `elevation oi a machine or apparatus embodying the invention. Fig. 2 is a plan view thereof. Fig. 3 is an end View. Fig. 4 is a section on the line :LL-a: of Fig. 1.

The machine comprises a suitable frame composed oi a series of uprights l, l, 1, with connecting bars 2 connecting said uprights. Mounted in suitable bearings at or near one end of the machine is a driving shaft 3 which may he provided with tight and loose pulleys A'L and 5. Secured to said shaft 3 is a sp1-ocket-wlien l (i, and mounted in suitable bearings at the opposite end oi' the l'nachine is a shaft 7 to which lis secured a corresponding sprocket-wheel S.

9 is the traveling czrrier, which in the machine shown is in the form of an endless belt which extends around and is engaged by the sprocket-wheels (S and S. As shown in the drawings, the endless conveyer 9 comprises a series of carriages l0, each carriage consisting of a body portion 11 with two axles 12, 12, secured thereto, said axles being provided with wheels 13 adapted to run on the track formed by the upper ends of the uprights 1 and by the connecting bars Q, said wheels being preferablyl flanged as shown in the drawings. The adjacent carriages are conncc ed together by suitable links 11, one on each side. The wheels 13 also constitute the means by which engagement of the eonveyer with the sprocketwheels is made, said `wheels engaging suitable forks 15 Yformed on said sprocketwheels. Each of the carriages 10 or the body portion .11 thereof is provided with suitable pins 16 to engage the usual holes in the last.

Rigidly secured to the central uprights I1. are two arms or brackets 17. Pivoted to the upper ends of said arms is a U-shaped frame 18, tho cross-piece of which is bent upward 4to form a yoke or support 19 upon which is placed or secured a pressure-weight Q0. As

shown in the drawings, the yoke 19 is provided with a projecting pin 21 which engages a corresponding hole formed in the bottom ofthe weight.

22 is the operating roll, the axle 23 of which is mounted in suitable bearings in the U-shaped frame 18. In order to arrest or limit the downward movement fof the U- shaped frame carrying the operating roll.,

` two supports QA-tfare provided, one' on each side ogt the machlne, said supports beingA 1n.

ing` thatthc operation `to be performed by the machine shown in the drawings is the rolling on ol the rag-filling sole, so called, and understanding that the endless belt 9 is continuously moving, the operator applies to the lasted shoe a suitable rag-lilling sole in proper position, and then places the lasted shoe with such rag-filling sole in position on the pin l@ of one ot' the carriages l0 in advance et' the pressure-roll Q2. As 'the endless belt travels along, the toe ot the lasted Shoe will be brought into engagement with the under side ot the operating roll 22, which roll will, as the lasted shoe is Carried thereunder, be pressed against the rag-filling sole by the action oit the weight 2() and will operate to roll said rag-lilling sole into close contact with the in-sole beneath the same. lli/Then the lasted shoe has passed fromY beneath said roll 22, the downward movement of said roll will be arrested by the engagement of the projections .25 with the supports or springs Q-t in a position where the toe of the next lasted shoe to be brought along by the endless conveyor will engage the opera-ting roll below the axis thereol1 and so that by the continued movement of said nextv lasted. shoe` the roll will be suiiiciently lifted to enable the shoe to pass beneath the same, the roll acting thereon with a pressure due to the weight Q0 referred to. YVhen the lasted shoe has passed beyond the operating roll it may then be taken oit of the endless belt `for the performance ot the next operations thereon, as lior example,cementing, applying the heel and toe tips and the foxing.

As will be seen, the rolling. of the sole upon the shoe in the machine or apparatus above described is effected by the joint action or coperation ot the pressure-roll and the endless bed, said movable bed serving to carry the lasted shoe beneath said pressureroll and to cause'said pressure-roll to act upon the sole from one end of the shoe t0 the othei;y as said shoe is carried thereunder. It will thus be seen that the operation of rolling on the sole is performed entirely automaticallyv and without any hand operation or intervention. lt will also be seen that the operation of rolling on the sole is 4.on the movable bed.A

vgreatly `facilitated by reasonvof fact that the operator mayv be .applyinga sole to al1-l other lasted upper` and placing it ,in position 3 It, will" be yunderstood that so broad features of the invention are concerned the movable bed, instead 'of heinginy far as the a reciprocating bed which travels back and forth beneath thepressure-roller. lt is preferred, however, to employ a movable' bed which is in the form of an endless belt as shown, because with such endless belt` con-.1 tinuously traveling 1n' one direction no time is lost and the soles may be rolled Von one lasted shoeafter another practically Without interruption.

lVhile in the foregoing description reference has been made particularly to the rolling on of a rag-illing sole, so called, it will be understood that the machine described may be employed forv rolling on any other sole which enters into the make-up of the shoe, as for instance, the cloth-lilling sole or the ont-sole. 1

While the contour of the operating roll is not material to the present invention, it is preferred to make said roll more or .less concave, as shown in Fig. 8, but it is to be understood that the contour of the roll is to be such as may be best adapted for the particular sole which is to be operated upon.

lVhile in the machine shown in the drawings a weight is employed for'producing the necessary pressure upon the operating roll, it will be understood that, it desired, a spring'may be Aemployed in place of such weight.

lVhat I claim as my invention and desire to secure by Letters Patent is:
