re a pairof links pivotallyssecured to the y bars 4,35, respectively.

As clearly disclosed in the aforementioned patent, upon swinging move ment of the lever 9 the slides 6 and 12 and the links 4 and 5 have imparted to them the proper motions for operating the wipers in the desired manner.

The wiper plates at, 2) herein illustrated are of the type disclosed in the patent to .l/Villard, 561,189, June 2, 1896, being pivotally connected at their inner extremities and being provided with'open-ended slots 17, 18

adapted for engagement by pins 19, 20 carried at the outer extremities of the respec- V tive links 4 and 5.

In accordance with the present invention, means is provided for removably securing the'wipers to the supporting slide 12, and

"reference may be had to Figs. 2, 3, 4 and 5 which clearly disclose the deta1ls of this securing means. Referring more particularformed at its upper extremity with a head 25, the cylindrical portion of said pin being also 'furnished'with a oircumferential groove as shown at 26; 'The" outer extremity of the supporting plate 12 is' formed with an openended slot or recess 27, the inner end of which is substantiallysemi-circular and conforms to the cylindrical portion 24o]? the pin 21, which may thusbe snugly seated in the bottomof the slot 27.

The member 12 is provided near its outer extremity with transverse guideways or bearings 28, 23 serving to guide a retaining pin 29, the shape of WlllCh is clearly disclosed in Fig 5; This pin is substantially cylindricalin form, but throughout a portion, of its extent is slabbedofl' to provide a flat surface 30, tlnssurface terminating in a shoulder 31 at one extremity. 32 18 a groove formed near the opposite extremity of said "slabbed-ofi' portion of the pin and extending atzright angles to the surface. 30. 33 is a lever armprovided with a finger-engaging ni'ember34, said lever arm being fixed to or integral with the pin 29 and extending in a direction parallel to the surface 30.

The pin 29 is normally located within the guideways 28, 28 and when so placed a stud 35 which. extends vertically downward through support 12-and transversely of the "bearing 28 engages the surface 30 of the pin 29, forming an abutment engageable with the shoulder 31 of the pin to prevent the complete removal of the pin from the bearing 28*. It will also be noted that when the pin 35 is in engagement with the surface 30, the pin 29 is secured against angular movement.

In, the employment of the parts above described, the pin 29 being in withdrawn position as shown in Fig. 3, the projecting portion 24 of the stud 21 which forms the pivot for the wiper members, may lee-seated with- Y in the recess 27 with the head 25 thereof bearing upon the upper surface of the support 12 and the rear portions of the wipers underlying said support. The retaining pin 29 is now slidably moved along the hearing 28 (being received within the circum ferential groove 26 of the stud 21) until its extremity is seated within the bearing .28.

When the pin has been carried into this position the slot 32 will have been brought opposite the pin 35, whereupon the pin may be rotated on its axis by means of the lever arm 33 until the slabbed-ofi' portion 30'of the pin 29 is in the position shown in Fig. 4:. In this position the pin 35 lies within the slot 32 and thus prevents any sliding move-' ment outwardly of the pin 29. In this position of the parts the wiper members are securely retained in position on the'support 12, while at the same time the securing pin 29 'is locked against accidental disengagement. 7

l/V hen it is desired to for substitution of others, it is merely necessary to rotate the pin 29 by means of lever 33 until pin or stud 35 is free fromslot 32' thereuponthe pin may be slidab-ly retracted to the position shown in Fig. 3 and the wipers removed bodily by disengagement of the stud 21 from the recess 27, the studs 19,

20 at the same time sliding freely from'the open-ends of the slots 17, 18 of the wipers.

As will be noted, when the locking pin occupies the position shown in Fig. 3, it is impossible for it to become displaced by turning on its axis so that it is ready to be returned to normal position. While as herein shown the stud 21 extends upwardly from the upper wiper only, it is contemplated as Within the scope of this invention that under some circumstances such stud might b'edi rected downwardly from 'the'lower wiperor 7 that portions of the stud might extend'both upwardly and downwardly for engagement with the support;

. Furthermore, while as herein disclosed the securing stud forms the pivotal connection to be fully within the scope of the invention to provide separate Wiper plates with independent studs in position to be secured upon the proper supporting elements by devices such as herein disclosed.

Having thus now described the invention and a. preferred embodiment thereof, to gether with details of construction and the remove the wipers V between the wipers of a pair, it is considered mode of operation thereof, what I claim and desire to secure by Letters Patent of the United States is,

1. In a lasting machine, in combination, a support having an open-ended slot therein,

a wiper plate provided with a member engageable with said slot, and manually operable means for retaining said member in polocking said pin against sliding movement sition within said slot.

2. In a'machine of the class described, in combination, a support having an openended slot therein, a Wiper plate, a member a pin slidably mounted in'said support and normally extending transversely across the open end of said slot.

4. In a machine of the class described, in combination, a wiper plate,'a support therefor, means for removably' securing said wiper plate to said support comprising a pin mounted in said support for both axial sliding and angular rocking, and means for when in normal position and against angular rocking when in retracted position. I

'tially flat longitudinal 5. In a machine. of the class described, a support, a wiper'plate having an element for engagement with said'support and means for normally retaining said element in op erative engagement with said support comprising a pin slidably mounted in guideways in said support, said pin hafving a substanace throughout a portion of its length, and an abutment member engaging said flat face and serving to prevent complete withdrawal of said pin from its guideWays.

6. A lasting machine having, in combina tion, a support,a wiper plate having a member projecting therefrom and engageable in extending a slot in said support, and means for nor mally retaining said member in said slot comprlsing a pin slidable transversely of said lot, said pin. being slabbed-ofi' throughout a portion-of its surface to form a substantia'lly flat face, and a fixed stud engaging said flat face. to prevent removal of the pin from the support, said pin having formed therein a transverse groove near one extremity and substantially at right angles to said face, said'groove whenbrought op-- posite said stud permitting angular rocking of said pin. a
