LASTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 635,129, dated October 17', 1899.

Application filed April 15, 1898. Serial No. 677,652. (No model.)

EATON, of c c are pivoted upon the ends of a rocking Boston, in the county of Suffolk and State of bar cl of rigid construction, pivoted upon a Massachusettahaveinvented certain new and stud or fulcrum d, projecting forward from useful Improvements in Lasting-Machines, of the shelf b at the front end of the bed-plate.

Thus far the construction described is no This invention relates to machines for lastdifferent from that illustrated and described ing over the heel and toe portions of boot and in the patent to Fred P.

The toe-clamp consists of a ary racks e and impart an accelerated forstrip 0 of leather or suitable flexible material, ward movement to the racks 6 6 this motion backed by rigid curved-arm or yoke sections being imparted to the wipers by the linksc c c, which are pivotally connected together the wipers being thus caused to move forward 45 at c and are provided with ears 0 0 conwith the carrier and to swing inward toward 5 nected to bell-crank levers c 0 'The ends each other, the segmental ribs moving in the of the bellcrank levers are connected by segmental slots of the carrier constituting the curved links 0 c with the inner ends of the pivotal connections between the carrier and arms a, the links crossing each other, so as the wipers. 50 to constitute equalizing connectionsbetween The described forward and inward move- Ioo ment of the wipers causes them to properly wipe the upper over upon the bottom of the last, the toe portion being wiped backwardly or lengthwise of the last, while the said side portions are wiped forwardly or crosswise of the last.

In order to adjust the wipers toward or from each other, a screw-bar h, journaled in a bearing h on the bedb and having a handwheel 77. has its end passed into the nut 0 so that by turning the screw-bar in one direction or the other the wipers may be caused to approach or recede from each other about a common center.

As has been previously stated,the toe-clamp is mounted upon a rocking bar, so that it is automatically adjustable by the engagement of a lasttherewith to fit a right or left last that is to say, the rocking bar may be swung upon its pivot, whereby when the median line of the toe part of a last is at an inclination to the median line of the machine the toeclamp will automatically swing to correspond thereto.

I connect the wipers with the toe-clamp, so that when the last and toe-clamp are brought into contact and the latter is automatically adjusted to fit the last the wipers are likewise automatically adjusted before the last comes into contact therewith. The connecting means consist of a bell-crank lever z', pivoted on the under side of the bed-plateb and connected by a link with the rocking bar. The other end of the bell-crank lever is provided with a stud t fitting in a slot in the end of a vibrating bar 9', pivoted at j to the said under side of the bed. The rear end of this vibrating bar is provided with a stud g, projecting into'a slot in the wedge g.

Now it will be seen that when the rocking bar is rocked about its center of motion the link 7 swings the bell-crank lever around its stud, and this in turn swings the lever j about its pivot-stud and thrusts the wedge to one side or the other, this depending upon whether the tilting bar at the front of the machine has been moved to correspond with a right or a left last. Hence the wipers, which are adjustable about a center of motion, are adjusted automatically in the same direction by the last before the latter comes in contact with them. The wiper and the adjusting mechanism is comparatively light, and little resistance has to be overcome when a shoe is brought into contact with the toe-clamp and they are adjusted in accordance with its shape.

The invention has been described as adapted for use in connection with toe-wipers; but it will be understood that it can be equally applied to heel-wipers.

Having thus explained the nature of the in- Vention and described a way of constructing and using the same, though without attempting to set forth all of the forms in which it may be made or all of the modes of its use, I declare that what I claim is- 1. A lasting-machine comprising wipers movable toward or from each other about a common center, a carrier having pinions, sliding racks intermeshing with said pinions, and connected to said wipers, adjustable racks intermeshing with said pinions, and mechanism for moving the last said racks relatively to each other, for the purpose of adjusting the wipers in the same direction about the said common center.

2. A lastingmachine comprising wipers movable toward or from each other about a common center, a carrier having pinions, sliding racks intermeshing with said pinions, and connected to said wipers, adjustable racks intermeshing with said pinions, and a bar for adjusting one of the last said racks relatively to the other.

3. A lasting-machine comprising wipers movable toward or from each other about a common center, a carrier having pinions,

sliding racks intermeshing with said pinions,

and connected to said wipers, adjustable racks intermeshing with said pinions, and a wedge for adjusting one of the last said racks relatively to the other.

4. A lasting-machine comprising a nonrotary head, wipers movable about a common center, slides connected to said wipers,means including a longitudinally-movable wedge for adjusting said slides relatively to each other to swing the wipers in the same direction about the said' center, and mechanism movable independently of said adjusting means for operating said wipers to approach and recede from each other.

5. A lasting machine comprising wipers movable about a common center, two pairs of opposing racks, one rack of each pair being connected to one of said wipers, mechanism for adjusting the other racks of said pairs relatively to each other, and a carrier provided with pinions intermeshing with the opposing racks of the said pairs.

6. A lasting-machine comprising wipers movable about a common center, a sliding block, slides interposed between said block and said wipers, and mechanism including coacting gearing interposed between the ends of said slides and said block for adjusting one of said slides relatively to the other, said parts being constructed and arranged whereby when the said block is moved the wipers are moved toward or from each other, and when the said mechanism is operated, the said wipers are swung in the same direction about the said common center.

7. A lasting-machine comprising wipers movable about a common center, adjustable slides connected to said wipers, a sliding block for adjusting said slides simultaneously in the same direction to move said wipers about their said common center, and mechanism interposed between said slides and said block for adjusting said slides in opposite directions.

8. A lasting-machine comprising wipers movable about a common center, adjustable slides connected to said wipers, a sliding block for adjusting said'slides simultaneously in the same direction to move said wipers about their said common center, mechanism interposed between said slides and said block for adjusting said slides in opposite directions, a movable clamp for the end of the shoe,'and connections between said clamp and said mechanism.

9. A lastingmachine comprising wipers movable toward or from each other about a common center, acarrierhavingpinions, sliding racks intermeshing with said pinions, and connected to said wipers, adjustable racks intel-meshing with said pinions, mechanism for moving the last said racks relatively to each other, for the purpose of adjusting the Wipers in the same direction about the said common center, a swinging clamp for the end of the ARTHUR W.
