LEATH ER-G LAZING MACH l N E.

SPECIFICATION formingpart of Letters Patent No. 426,225, dated April 22, 1890.

Application filed July 11,1889. Serial No. 317,152. (No model.)

To aZZ whom, it may concern:

Be it known that I, GEORGE V. ANDERSON,

a citizen of the United States, residing at il-- mington, in the county of New Castle and State of Delaware, have invent-ed a new and useful Improvement in Leather-Glazing Machines, which improvement is fully set forth in. the following specification and accompanying drawings.

My invention consists of improvements in leather-glazing machines embodying means for operating the agate or glazing-piece, also means for adjusting said agate; furthermore, of means for operating the bed, and finally means for adjusting said bed.

Figure]. represents a side elevation of a leather-glazing machine embodying my invention. Fig. 2 represents a side elevation of a portion at a right angle to Fig. 1. Fig. 3 represents an end view of the horse and adjacent portions on an enlarged scale.

Similar letters and numerals of reference indicate corresponding parts in the several figures.

Referring to the drawings, .A. designates a goose-neck or arm, which is properly supported and has on its upper end the guides or ways B, extending horizontally, and receivin g between them the sliding head (1, to which motion is imparted by means of the bar or rod D, which is pivoted to said head, and has pivoted to it a lever E, the latter being mounted. on a suitable standard E, and having pivoted to it the arm F of a yoke G, which encircles an eccentric II, which is connected with the driving-shaft J.

K designates a cam, which is secured to said driving-shaft and engages with a sliding rod or bar L, said shaft being mounted on a standard M, and said rod being fitted in guides N on the arm A.

I designates a rising and falling bar, which is located below or adjacent to the guides B,

and supported on its ends on the parallel arms Q, which are pivoted to said bar, and also to the upper portion of the arm A. One of the arms Q has a limb R secured to it, forming an elbow-lever, which is connected with the sliding bar L by means of a pivoted link S,

whereby rising and falling motions may be imparted to the bar P.

T designates the agate or glazing-piece, which is secured to a rocking or swinging head U in any suitable manner, said head having its axis on a vertical bolt V, which is 5 5 connected with the sliding head G, and also connected by a pivoted link with a sliding head X, which is fitted on the bar or rod 1. The bolt V passes freely through the sliding head C and carries a coiled spring Y and nuts Z Z, said spring bearing against the nut Z and the under side of the sliding head C,

so as to hold the agate or piece T down to its work and allow the same to yield when so required, the nut Z being employed to adjust the tension of the spring and the nut Z to adjust the position of the agate T, it being seen that the sliding heads G X are parallel to each other and serve to move the agate in opposite directions and raise and lower the same, as will be hereinafter set forth.

Below the agate is the bed 1, on which the leather to be glazed is supported, said bed being of the form of an octagonal block and having journals 2, which are mounted on vertical rods 3, the latter being guided in eyes& of cross-bars 5, the latter being sustained on standards or uprights G. The rods 3 pass freely through the eyes at and carry the coiled springs 7 and nuts 8 9, said springs bearing against the nuts 8 and eyes 4, whereby the bed is held up to its work and permitted to yield when so required. The nuts 8 are employed to adjust the springs 7, and the nuts 9 to adjust the position of the bed with relation to the agate.

The standards 6 have mounted on them a rotatable rod 10, which is parallel with the bars 5 and carries cams or arms 11, which bear against the lower bar 5, the latter being ver-- tically movable on the standards 6 and held in its uppermost position by said arms 11. \Vhen, however, the rod 10 is properly rotated, a handle 12 being provided for that purpose, the arms 11 release the lower bar 5 5 and permit the same to drop, whereby the bed is lowered and cleared of contact of the agate. One of the journals 2 has secured to it a ratchet 13, with which engages a pawl 14, having an arm 15 mounted loosely on-said journal and operated by a rod' 16, the latter being connected with an elbow-lever 17, which is mounted on an arm or bracket 18, secured to the adjacent rod 3, said elbow-lever being adj ustably connected with an arm 19, which is pivoted to the lever E. The ratchet 13 is engaged by a check-pawl 20, mounted on the rod 3 and serving to prevent improper return motions of the bed 1.

The operation is as follows: Power is applied to the shaft J, whereby the lever E and bar L receive motions, the effect of which is the movement of the sliding head 0 to and fro and the elevation and depression of the bar P, the sliding head X following the motions of the sliding head 0 and those of the rising and falling bar P. Owing to the link WV, the head U is turned on its axis so that the agate is brought into contact with the leather upon the bed, and then sweeps over the same, remaining in contact therewith. IVhen the agate has completed its throw, the bar P lowers, whereby the head U turns on its axis, thus raising the agate clear of the leather. The slide-head C then makes its return motion, and the agate is carried with it clear of the leather back to the starting-point. Owing to the connection of the elbow-lever 17 with the lever E, the'rod 16, previously lowered by the first motion of said lever, is now raised, whereby the pawl 14 presses against the ratchet 13 and rotates the same, thus rotating the bed 1 and presenting another face of the latter to the top, the leather then being placed on said face. The bar P now rises, and the sliding head O begins its advance motion, the agate being again lowered and presented to the leather and carried over the same, thus continuing the glazing operation, which is repeated until the work is finished.

Owing to the rotation of the bed and the presentation of its faces successively to the top, heating of said faces is prevented.

While the spring Y bears downwardly on the head U, and consequently on the agate, it also serves to lower the bar P, and consequently the sliding bar L.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a leather-glazing machine, a rising and falling bar with a sliding head thereon and a sliding head on the frame or arm of the machine, in combination with an agate-carrying head, which is connected with the two sliding heads, and a bed, substantially as described.

2. In a leather-glazing machine, a swinging head carrying an agate and pivotally connected to horizontal sliding heads, one of which is mounted on the frame or arm of the machine, and the other one is mounted on a rising and falling bar, the said parts being combined substantially as described.
