E. E. ORR. HEEL NAILING MACHINE.
No. 375,458. Patented Dec. 27, 1887.
UNITED STATES PATENT OFFICE.
EDWARD E. ORR, OF WEYMOUIH, MASSACHUSETTS, ASSIGNOR TO THE NATIONAL HEELING MACHINE COMPANY, OF PORTLAND, MAINE.
.HEEL-NAILING MACHINE.
- SPECIFICATION forming part of Letters Patent No. 375,458, dated December 27, 1887. Application filed December 29, 1886. Serial No. 222,864. (No model.)
To all whom it may concern.-
Be it known that I, EDWARD E. ORR, a citizen of the United States and a resident of Weymouth, in the county of Norfolk and State-of Massachusetts, have invented a new and useful Improvement in Heel -Nailing Machines, of which the following is a full, clear, and exact description, reference being had to the accord panying drawings, forming a part of this specification in explaining its nature, in which- Figure 1 is a view in section of a machine having my invention. Fig. 2-is a plan view of the jack and bed. Fig. 3 is a detail view.
In heel-nailing machines having a last or work support horizontally movable in relation to the templet and nailing device there is upon the movement of the work-support toward the templet or of the templet toward the work-supportaliability of theworksupport being thrown or moved horizontally slightly in-a forward direction, and this is especially liable to happen if the last or work support is well rounded backward at the heel and il" stock well filled with oil is used for insoles; and my inv vention relates to adevice for positivelylocking the work-support so that it cannot be thus slipped or moved.
The invention is represented as applied to a national heeling-machine; but its use is of course not limited to said machine- Arepresents the templet; B, the nail-carrier; O, the crosshead which carries or supports the revolving head; 0, carrying a gang of awls, a gang of drivers, and a top-lift-attaching device.
1) is the last or work-support.
e is the spindle supporting the same. a isthe plate, which has a post, 6 carrying the spindle 6. This plate slides in the ways 0. in the bed of the machine to move the last or work-support in and out of position beneath the templet.
F is the back-stop, which preferably is made adjustable horizontally. The sliding jackplate e carries a' block, G, having ratchet: teeth 9 placed closely together.
To the guide-plate 9' there is fastened a lever-pawl, 9 which is arranged so that its point or latching end is held in contact with the teeth of the ratchet-block. This leverpawl is pivoted at g, and a spring, 9 maintains its latching end in contact with the teeth. A pin, 9", prevents the end of the lever-pawl. from being thrown too far into the slideway when the pawl is not in contact with the ratchet-teeth as. for instance, when the jack is moved forward.
In operation, thejack is moved in until the back end of the plate e comes in contact with the back-stop, and the pawl or latch then antomatically engages the teeth of the ratchetblock and rides upon them until thejack comes to rest, when it looks or moves behind the one then in line with it, and thereby serves to lock the last or work support firmly between the back-stop and the end of the pawl. By providing the ratchet-bar with a number of teeth it is of course apparent that the jack may be locked in any desired position, which position is of course determined by the location of the back-stop.
Having thus fully described myinvention, I claim and desire to secure by Letters Patent of the United States 1. The combination, in a heel-nailing machine, of the last or work support, the jack having the ratchet-bar G, and the detent or locking-arm g", substantially as described.
2. The combination of the last or work support, the jack-plate g, the back-stop F, the ratchet-bar G, carried by the jack-plate, the detent or pawl 9 pivoted as described, and having the handle and a spring, 9 all as set forth.
3. The combination of the jack having the ratchet-bar G, the spring-pawl 9 having the handle, the spring and the pin 9, substanv tially as described.
