Abstract
Abstract A horizontally adjustable shuttle mount includes a main frame mountable upon a column of a press which has a bed. The frame includes a pair of horizontal vertically spaced tubes of square cross section with the upper tube having a pair of top walls inclined at 45 degrees to the vertical. The lower tube has an upright side wall. An upright carriage plate spans said tubes and is adapted to mount an automation unit for loading blanks and unloading formed panels from the bed of the press. A pair of 90-degree related cam roller followers are journalled upon opposite end portions of the carriage plate upon axes inclined at 45 degrees to the vertical and are supportably mounted upon the upper tube top walls. A pair of laterally spaced cam roller followers are journalled upon lower portions of the carriage plate and operatively engage the lower tube side wall. A power device on the frame is operatively connected to the carriage plate for longitudinally adjusting said plate along the frame for prelocating the automation unit with respect to the press bed.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
218 words
A horizontally adjustable shuttle mount comprising a main frame adapted for mounting upon and transversely of the column of a press having a bed and used in the manufacture of automotive, truck or refrigerator panels; said frame including a pair of horizontal, vertically spaced tubes of square cross section, the upper tube having a pair of top walls inclined at 45 degrees with the vertical; the lower tube having an upright side wall; an upright carriage plate spanning said tubes and adapted to mount an automation unit for loading blanks and unloading pressed panels from the bed of said press; a pair of longitudinally spaced bearing blocks mounted adjacent the upper end of said carriage plate; a pair of 90 degree related cam roller followers journalled upon each bearing block upon axes inclined at 45 degrees to the vertical supportably bearing upon said upper tube top walls; a pair of longitudinally spaced bearing blocks mounted adjacent the lower end of said carriage plate; a cam roller follower journalled upon each latter bearing block upon a vertical axis and operatively engaging said lower tube side wall; and power means on said frame and connected to said carriage plate for longitudinally adjusting said plate along said frame for pre-locating said automation unit upon and with respect to the press bed.
Claim 2
Dependent Claim
218 words
A horizontally adjustable shuttle mount comprising a main frame adapted for mounting upon and transversely of the column of a press having a bed and used in the manufacture of automotive, truck or refrigerator panels; said frame including a pair of horizontal, vertically spaced tubes of square cross section, the upper tube having a pair of top walls inclined at 45 degrees with the vertical; the lower tube having an upright side wall; an upright carriage plate spanning said tubes and adapted to mount an automation unit for loading blanks and unloading pressed panels from the bed of said press; a pair of longitudinally spaced bearing blocks mounted adjacent the upper end of said carriage plate; a pair of 90 degree related cam roller followers journalled upon each bearing block upon axes inclined at 45 degrees to the vertical supportably bearing upon said upper tube top walls; a pair of longitudinally spaced bearing blocks mounted adjacent the lower end of said carriage plate; a cam roller follower journalled upon each latter bearing block upon a vertical axis and operatively engaging said lower tube side wall; and power means on said frame and connected to said carriage plate for longitudinally adjusting said plate along said frame for pre-locating said automation unit upon and with respect to the press bed.
Claim 3
Dependent Claim
66 words
In the shuttle mount of claim 1, said power means including a drive sprocket and spaced idler sprocket journalled upon horizontal axes adjacent opposite ends of said frame; a sprocket chain extending around said sprockets with its ends secured to opposite sides of said carriage plate respectively; and a power drive means mounted upon said frame at on end thereof and connected to said drive sprocket.
Claim 4
Dependent Claim
42 words
In the shuttle mount of claim 2, said power drive means including a motor mounted upon said main frame having an output shaft; a speed reducer coupled with said motor output shaft and having an output shaft connected to said drive sprocket.
Claim 5
Dependent Claim
36 words
In the shuttle mount of claim 1, a pair of stop plates mounted adjacent ends of one of said frame tubes, in the path of reciprocal movements of said carriage plate for limiting maximum movements thereof.
Claim 6
Dependent Claim
89 words
In the shuttle mount of claim 1, a carriage lock rod underlying the lower frame tube and secured thereto along its length; and a power clamp mounted on said carriage plate having a normally retracted clamp arm spaced from and movable along said lock rod; said power clamp including a power means and a linkage interconnecting said power means and clamp arm for selectively moving said clamp arm into frictional locking engagement with said lock rod for securing said carriage plate in a predetermined position relative to said press.
Claim 7
Dependent Claim
77 words
In the shuttle mount of claim 1, said automation unit including a jaw assembly having a pair of jaws with power means to open and close the jaws; a horizontally disposed support assembly mounting said jaw assembly and reciprocally movable in a plane at right angles to the plane of movement of said carriage plate; and a horizontally disposed adjustable stroke rectractor mechanism mounting said support assembly and adjustably suspended from and mounted on said carriage plate.
Claim 8
Dependent Claim
53 words
In the shuttle mount of claim 6, said adjustable stroke retractor mechanism including an elongated cylinder housing having an exterior trackway; a carriage movably mounted on said trackway and connected to said support assembly; and a reciprocal piston rod and cylinder assembly within said cylinder housing, with said rod connected to said carriage.
