JOHN JAMES HEYS, OF LYNN, MASSACHUSETTS,

I TO UNITED SHOE MACHINERY CORPORATION,

-PORA'1ION OF NEW JERSEY.

ASSIGNOR, BY MESNE ASSIGNMENTS,

SOLE-MOLDIN G MACHINE.

To all whom it may concern Be it known that I,-JoHN J. Here, a citizen of the United States,i.residing at Lynn, in the county of Essex and State of Massachusetts, have "invented certain new and useful Improvements in 'Sole-Moldin Machines; and I'do hereby declare the. ollowing to "be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertalns to make and use the same. I

, The present invention relates to molding machines and more particularly to machines of-'this" type employed for molding soles prior to their incorporation in aboot or shoe.

--In. molding soles which have been tempered or softened by immersion in water or other suitable Iiq'uidit is desirable to pro vide means for collecting'and disposingof the liquid which oozes from the sole under pressure to prevent this liquid from coming into contactwith and corrodingthe moving parts of the machine. r

The obi ect of the present invention, there fore, is to provide means:for' inclo'sing the lower mold in a manner to'insure' the col lection of all'of the liquid which is squeezed from the sole, which at the same time aflords an adequate support for the mold duringthe sole pressing operation.

With this object in view a feature of the invention contemplates the provision of" a of a slide supporting'the'mold,inclosing single integral casting having walls which inclose the mold, a boss co-extensive in area with the mold and adapted to accord a firm supportfor-the latter, and gutters surrounding the boss and sloping toward a discharge opening which passes through thebase' of the casting. f i

A further feature of the invention consistsin the combination with a. sole mold,

walls surrounding 'the mold, a discharge opening adapted to lead liquid away from and belowthe'slide, and gutters surrounding the mold within the walls'and-sloping toward and communicating with the discharge opening.

In the simplest and most efficient form of the invention which has yet been devised, the improved receptacleor pan is adapted for attachment to-existing machines, and to 1 v Specification of Letters Patent.

Application filed November 2, 1917. Serial B o.

Patented Jan. 21, 1919.

this end is formed as a single integral casting having a boss extending above and below the base of the pan and adapted to rest upon the mold slide andsupportthe mold directly from the'slide. This'pan is secured to the slide in any suitable manner and is adapted to receive the usual ,type of mold having a.

pin-receiving recess in the bottom and a slot in one end. Thisconstruction, accordingly,

serves the dual function of a support for v the mold and a receptacle for inclosing the of a moldingmachine embodying the several features of thei'nvention in their preferred forms; Fig. 2 is a plan view of the improved drip pan; Fig. 3 is a cross section in elevation of the drip pan with a mold supported thereon in a position of pressure;

- and Fig. 4; is a detail illustrating a cross section of the pan taken upon the line 44 of Fig. 2. I

The illustrated embodiment of the inven: tion is shown in connection with a machine of the type disclosed in the co-pending application ofhHeys, Serial No. 26,551, filed May 7, 1915. This machine comprises a stationary pressing fornrl and a cooperating sole supporting form 2, which are adapted, as shown clearlyin Figs. 1 and 3 of the drawings, to impart the desired shape to a sole'priorto its incorporation in a boot or shoe. The lower mold 2 is carried upon a slide 4 whi h is supported in a head 5 moving virtually between guide rods 6. Accord ing .to the usual operation of machines of this type the vertical movement ofthe head 5: causes a simultaneous horizontal movement of the slide 4 relative to the head to carry the lower mold 2 into alinement with the upper mold 1, the lower mold being positioned at the front of the machine out OF PATERSON', NEW JERSEY, A COR- of alinement withrthe uppermold-for the convenient application and removal of the shoe soles.

During. the solemolding operation the liquid which is. squeezed out of .the sole runs down upon the machine if no provision is made for collecting it. This tends to corrode the moving parts of the machine, more particularly the ways in which the slide moves; and is,- ini consequence, highly ob jectionable. It is essential-that this liquid shall be collected and that thereceptacle or P nni r e mbod d i h adl n t out interfering with their. normal operation or ,otherwise I detracting from the eiliciency.- To; this-end the present inventioncontemplatesdthe, provision of a drip pan surrounding the lower. -mold and in which the latter is supported, and having no'provision Op l/h 6? egressQof liq id therefromexceptthrough/a suitablydisposed discharge open: ing; Arcording tothevpresent invention the pan, consists ..ot;a. single integral casting ma I o a m te ial, I s flieie ly. s q g; t

The two' gutters 1-7 are connected at the discharge end bya gutter 21 forming, in 'efliect, 'a' single guttercommunicating with the discharge opening. The entire pan is: a single casting ,having the base, wall and guttersformed integral therewith: and effectually preventing the escape of moisture on to-the-mold slide 4c pr other moving. parts-of the-machine. It will-be noted fromjaninspection of Figs. 3

k and 4: that the boss-l2, which forms the base portion, extends below the-under-side'of the pan and is provided with'a face resting upon the mold slideand afiording a firm foundation for that portion of the pan -;which is directlvsubjected to the'pressure ofthe mold; The end of the pan opposite the base is provided with a plurality of depending feet 22, formed integral therewith and engaging with the mold slide, as shown 1 clearly in Figs.- 1 and 3.

While: it. is preferred to employ the specific construction and arrangement of parts;

shown and described, it will i be understood that this construction and arrangement: is

not essential except so far asspecified in the claims,'and mayube changed ormodified'l without departing from the" broader tea-' tures of the invention. I

The nvention havingwhat is claimed is:
