xiip to the position ofj ig. l.

(4 indicates the shaft of the turret which is rotatably mounted in the cross head is of a nailing machine, of the character above referred to, and o the plate and top lift holder, which is connected to the turret and is "pro- Vided with a well-known means for holding a top lift 6 thereon. In devices of this character it customary for the operators assistant to place the top lift on the holder While the latter is disposed face up in a horizontal position, the turret being rotated through half a circle to carry the top lift into a position in which it is spanked onto the heel. A. tank 0 is provided which is mounted upon the cross head of the machine, and .contains a suitable liquid cement, ordinary fish glue generally being employed for this purpose. At the lower end of the tank a discharge chamber a" is provided, said chamber having an outlet opening 0 which is adapted to be closed by a conical shaped regulatii'ig valve (Z, as shown in l ig. Said opening c leads to the middle of a flat face 1;, the plane of which is slightly inclined from the vertical. .l shaft 0 is rolalably mounted in the cross head and a carrier arm f is mounted on said shaft, said arm preferably being provided Willi a counter weight f, and-a spring g is connected to said arm and normally acts to hold the arm j in the position of Fig. 1. sleeve is telescopically mounted on the end of said arm 7, and a spring a is interposed between a head 72, on the end of said sleeve IL and the bottom .of a chamber formed in lhe end of arm f, See Fig. l, said spring normally acting to push said sleeve away from the shaft c. cementing pad I: is mounted on the h ad apivol'al connection preferably being provided between said pad and said head, as shown in Fig. l, the arraugcim nt being such that the pad .0 is normally pressed against the face (1" of the cement tank, with the discharge orilice opposite the center of said pad, so that the latter may act to close said opening when in such position.

A stop arm j is provided on the arm f to limit the reciprocating movement of the sleeve /1. on said arm in both directions. A spring catch at is mounted on the shaft/1 in position to engage a projecling pin '11 securcd to the sleeve /i, and a linger o is mounted on the cross head and is adapted to hold said spring catch at. out of engagement with the pin 1/, when the arm f isdrawu I A curved lin ger is rigidly secured to the shall 1', and an arm is secured lo the turret, and is provided with a horizontally projecting pin '2' so arranged that, when the turret is rotated to the right, it. will engage said linger 7).

The operation of lhe above de cribml device is as follows: The top lift 6 having been placed upon the spankcr plulc, or n the holder therefor, the operator rotates the f upwardly.

shaft (1 to the right tot urn the turret to the position in which the top lift may be spanked onto the heel. As the turret is rotated the pin r strikes the finger p and causes said arm j to be swung downwardly, so that the top lift and the pad is are swung toward each other convergently, until they meet and the pad is is pressed against the middle portion of the top lift, the jointed connection between the pad holder and the head h perinittingthe face of the pad to bear evenly on the snrfaceof the lift while it is in contact therewith. As the pad h has rbeen resting against an open orifice it will be saturated with the glue or cement, and will apply a suitable quantity thereof-to the face of the top lift. It will be observed that the pad is is brought in contact with but a portion of the cement constituting the source of supply and that this amount may be varied by adjusting the valve (Z, thus permitting the cement: applied to said pad to be of a predetermined amount. It will also be observed that the area of the top lift covered with cement is determined by the area of the face of the pad is. The portion of a top lill. covered with cement by the cement-applying mechanism is consequently under all conditions of a predetermined area. As soon as arm f is 'swung downwardly the spring catch in will be moved away from the linger 0, permitting said catch to swing upwardly, so that, as the sleeve is pressed hack on the arm f, in moving to the full line position of Fig. 3. its pin a will be carried over the tooth on the spring catch in and will he thereby prevenlcd from moving outward or downward, as the lift is moved out of engagement with the pad, and the parts assume the dotted line position of Fig. 3. onlinucd downward movement of the turret will cause the pin 1 to be carried out of contact with the linger 2, so that the spring will then be free to act to swing said arm The sleeve /L will be held back by the catch m until it is directly opposite lhc l'acc r and then the end of the catch will strike the linger o, and be drawn downwardly. permitting he spring 2' to force the pad fi' against the face v". the parts thereby being returned to the initial position. Y Dur ing the lime-when the pad is being swung down by the turret and is returning to its -duringlhc lime when the pad is out of conlat-l lhercwilh. to spread over said face, in-v stead of dripping from the face, as it other wise might. Moreover, as the cement is caused to spread over the race, a more unimcaus for moring said pad, simultancously a l-eyes outlet openings 0 anti that it normally covers said openi opening being exposed tor a sh mterra only, during the movement or the t p lif into attaching" position. This feature, outlet is normally covered. is of advantage in preventing clogging oi said outlet and e aporation of the liquid components of the cement. Exposure of said outlet causes the cement sustained I. ercon to gradually dry or harden and consctpiently interferes with the iiow of cement thcrethrough, renders the dried cement useles' and consequently in valves ex 'icuse, and prevents application of a uniform fuantity of cement to the top lifts. it will also be observed that the cement applyingface of the pad Z: is normally covered, said face in the construction shown normally lying in contact with and being covered byzthc face 0 to wl -ch cementis supplied througrhihe outletv c. The cement upon said pad and upon said face 0 is thus prevented from drying through continual exposure. Having thus described our invention. what we claim as new and desire to secure by Letters lhitent isz l. in combination with a heeling machine turret bearing a lop lii't"'holder, a movably mounted cement carricr adjacent said holder and means for moving the same sinuiltaucously with the turyetinto engagement with the lift as it carri by the turret in said holder. suhstanti as described.
