p fic i n f Letters a n Patented Maya, 1919.

Application filed August 21, 1917. serial No. 187,489.

To all whom it may concern:

\Venham, in the county of Essex and of Massachusetts, have invented certain Improvements in Insole-Heel-Seat-Smoothing Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters 011 the drawings indicating like parts in the several figures.

This invention relates to maohmes for a boot or shoe.

It is customary to attach a heel to a shoe by means of nails driven from'the' outside through the heel, the outsole and the insole, the ends of the nails bein fthe shoe on the heel portlon of the insole and being covered in the finished shoe by a heel pod, or sock lining. It frequently happens that the clenched ends of these heel attaching nails project slightly above the surface of the insole and thereby cause discomfort to the wearer of the shoe. The object of the present invention is to provide a machine which will effectually smooth and to an extent shape the heel portion of the insole so as to produce a comfortable support for the heel of the wearer of the shoe.

One feature of the invention comprises a shaft, a cutting tool mounted upon the end thereof, a suction conduit the mouth of which extends around said tool and serves as a gage to limit the depth of cut of said tool, and means for rotating said shaft. With this construction the heel seat of the insole may very quickly be smoothed and shaped, the suction of air through the conduit acting to remove whatever dust or chips are formed and leaving the inside of the shoe clean.

This and other features of the invention, including certain details of construction and combinations of parts, will loe described in connection with an illustrative machine and pointed out in the appended claims.

Referring now to the accompanying draw- 1ngs,

The figure is a side elevation of a machine in which the present invention is embodied, a shoe being shown in position to be operated upon. 7

Mounted on. or fast to the head. of the maportion of the insole of clenched inside chine is a suction conduit comprisinga main Be it known that I, BERNARD T. LEvEQUE. a citizen of the United States, resldin at tate having a slightly convex cutting face adapted to form a slightdepression in the heel portion of-Ithe insole of a shoe, is fast to the lower end of an uprightshaft 9 ournaled in;

a bearing 11 which is integral with the main portion 3 of the conduit.- The main portion 3 and the end portion 103 are connected by a lap joint as shown to permit vertical adjust ment of the end portion. A screw 13 which passes through a slot 15 .in the'end portion and is threaded'into a boss on the bearing 11 provides means for holding the end portion- 103 in adjusted vertical position. A pulley 17 is fastened tothe upper end of the shaft 9 by a pin 19; and a belt 25 runs around this.

pulley, over guide pulleys 27 and around a pulley 29 on the driving shaft 31.

In the operation of the machine, the conduit is adjusted until the tool 7 projects the desired distance below the mouth 5. A shoe is then pressed up against the tool in the manner indicated in the figure whereupon the tool smooths and shapes the heel seat of the insole, the dust and chips generated during this operation being carried away through the suction conduit. If after repeated operations the to ol'loecomes clogged, a trcadle ll may be depressed to raise a clearing brush 33 into contact with the tool. The brush is rotatably mounted on one end of an arm 35 which is pivoted to the frame of the machine at 37, the other end of the arm being pivotally connected to a treadle rod 39 which is connected at its lower end to the treadle.

It should be particularly noted that the mouth of the suction conduit, by arresting the upward movement of the shoe, serves as a gage to determine the depth of out of the tool and that thereby a very compact and efiicient construction results.

Although the invention has been set forth in connection with a particular machine, it should loe understood that the invention is not limited in the scope of its application to the particular machine which has been. shown and described.

Having thus described my invention,

as new and desire to secure by Letters Patent f theUnitd States: v I

1. A m achineof the class described, hav-I 5 ing, in combination, a'shaft, a cutting tool mounted upon the end therepf a stationary suction conduit the mouth of which extends around. saidtool and serves as a gage to limit the depth of cut of said tool, and

means for rotating said shaft.

f abhineofthe described, havii combination; an upright shaft, a cuton the eiid theredf,a sta tron conduit through which said theiho'uth (if said conduit exi fl an, s v a a mine the depth of eut of said ans for rhtatin'gsaid shaft.

4, A name (if as: aesdeserib d,hav'- as maa; fliiPfis c ting tool mounted oh-the end thereof, a su'c tion conduit through Which said shaft passes, the mouth of said conduit extending around said tool and serving as a gage to determine the depth of out of said'toohme'ans for rotating said shaft, and means for producing relative adjustment between said shaft and the mouth of said conduit.

5. An insole heel seat smoothing machine, having in combination, a rotary shaft, 40 an end milling cutter mounted on the end thereof, the construction being such that the shaft may be caused to project into a shoe to bring the heel portion of thein'sole there of into contact \vith the cutter,- and a suctioii'conduit having its mouth encirclingthe cutter and shaped 'to permit the cutter to operate close to the heel end of the insole.

6. An iiiso'le' heel seat smoothing 1n-'a-' chine, havirig in combination, a rotary shaft, an end milling cutter mounted on the end thereof and shaped as smooth the heel por-- tion of the insole of shoe, a suction conduit adapted to protect the lining of the shoe from the action of the cutter, and means whereby relative adjustment between the cutter 'ahd the Iriouth of the cohduit may be produced to varythe depth of out made in the insole. I I a V In'testimony whereof Ihave'signed my name. to this specification.
