MAURICE S. FINCH, OF ST. JOSEPH, MISSOURI, ASSIGNOR TO SPECIALTY SHOE MACHINERY COMPANY, OF ST. JOSEPH, MISSOURI, A CORPORATION OF MIS- SOURI.
Specification of Letters Patent.
Patented July 18, 1916.
Application filed April 5, 1915. Serial No. 19,196.
To all whom it may concern Be it known that I, MAURICE S. F rNoH, a citizen of the United States, residing at St. Joseph, in the county of Buchanan and State of Missouri, have invented certain new and useful Improvements in Adjustable Anvils for Shoe-Nailing Machines, of which the following is a specification.
My invention relates to shoe machinery and more particularly to anvils for use in connection with shoe nailing machines.
The particular object ofjmy invention is the provision of an anvil for this type of machine that is capable of adjustability whereby a change may be quickly made from a short nail to a large nail or vice versa. As is well-known to those skilled in this art, the anvil moves upwardly and meets the nail while the latter is being driven and the motive for actuating the nail-driving mechanism is usually common to the anvil plunger or rod, both mechanisms being operable by means of a single foot-treadle in manually operated machines.
WVith this in mind, it is also an object of my invention to provide means for adjusting the anvil or its rod without affecting the nail driving mechanism. j
A still further object is to construct the adjusting devices in as simple a manner as possible so that it is easily and quickly operated for nails of different sizes or for driving or clenching the nails at different depths in the sole or heel of the shoe. And lastly, it is an object of my invention to provide an anvil with adjusting means that are economical to manufacture and do not mate'- riallyadd to the cost of the machine to the user.
These objects I prefer to accomplish by the means and in the manner hereinafter fully described and as more particularly pointed out in the claims, reference being had to the accompanying drawings forming a part of this specification wherein similar reference characters indicate the same parts in the various figures. p
In the drawings :Figure 1 is a side elevation of'the standard of a Well-known shoe nailing machine having a portion of the cas ing broken away to disclose my invention applied to the anvil thereof; Fig. 2 is a fragmentary vertical section, drawn to a larger scale showing in detail the adjusting elements; Fig. 3 is a transverse horizontal section on line 3-8 of Fig. 2, and Fig. 4 is an enlarged detailof the particular locking pawl employed in connection therewith.-
Referring to the drawings, and more particularly Fig. 1 thereof, it will be observed A represents a suitable hollow standard that is preferably rectangular shaped in horizontal section having its lower edges flared outwardly to form a basal flange and provided at its upper end with frustum-shaped extensions B and C. The former of these extensions (B) affords bearings for journaling the upper portion of the vertically disposed operating plunger D of the nail drivin mechanism while the latter extension (6) journals the upper portion of the vertically reciprocable rod 5 upon the upper extended end ofwhich the anvil 6 is supported. This anvil rod 5 has its lower end journaled in an L-shaped bearing bracket 7 secured to and projecting laterally from the inner surface of the adjacent wall of the standard,'and mediate these bearings said rod is tapped transversely by a cross pin 8 for supporting a coiled expansion spring 9 surrounding the rod between said pin and its upper bearings.
Mounted in axial alinement below supporting rod 5 .is an adjustable rod 10 slidingly journaled in bearings 12 secured laterally to said standard wall. I Said adjustable rod 10 is preferably provided at its lower end with bifurcations 13 that are adapted to pass upon each side of and be secured to a substantially L-shaped foot lever 14 by means of a cross-pin 15 which foot lever is pivoted at the angle of its larger and shorter arms to a pair of parallel lateral ears 16, 16, projecting from the exterior of the standard on each side of a transverse slot 17 formed therein. The foot lever preferably extends transversely across the interior of the standard so that its inner end is adjacent a verti cally elongated slot 20 in the opposite wall thereof where said treadle is provided with an enlarged head 21 from which two parallel lateral studs 22 and 23 project. A segmental shaped plate 24 is secured to the outer surface of the standard wall surrounding the slot 20 and said plate is provided with a vertically elongated slot 25 one of the sides of which is provided with a double row of ratchets' or teeth 26, arranged in alternate relation to each other.
Stud 22 above'mentioned has two pawls 27 pendently mounted thereon that are kept normally in engagement with said teeth by suitable springs 28 while the foot lever itself is forced toward the teeth by a fiat leaf spring 29 secured to its end and projecting into said slot 25 so that it bears against the edge opposite said teeth.
The pivotal bolt 18 upon which the foot lever is fulcrumed is preferably considerably smaller in diameter than the opening 19 in the lever arm so that the lever may be rocked laterally as indicated in dotted lines in Fig. 3, for the purpose of rotating the pin 23 about the pin 22 as its axis, thereby causing the pin 23 to contact the shoulder of the pawl 27 (Fig. 4 pulling it out of engagement with the ratchet teeth 26 and thereby permitting of the adjustment of the rod 10.
The upper end of adjusting rod 10 is preferably provided. with a collar 30 that is rigidly secured thereto and is provided with a suitable bifurcated bracket 31 that affords a fulcrum for a bifurcated link 32 that has its shorter hooked end 33 terminating below and in engagement with the lower end of anvil rod 5. The bifurcations of link 32 are adapted to pass on each side of plunger shaft D and are pivotally mounted in the upper ends of a vertically disposed substantially 'Y-shaped link 34 that has its lower end pivotally mounted in a lateral lug upon a collar 35 surrounding the plunger shaft D.
From the above it will be seen that by depressing foot lever 14- the adjusting rod 10 will be forced upwardly thereby raising the adjacent end of bifurcated link 32 and correspondingly elevating the anvil rod and anvil engaging the hooked end of said link. And when the plunger D is depressed to operate the nail drive mechanism the link 32 will be rocked on its fulcrum and its hooked end 32 will raise the anvil rods and anvil to meet the nails. It will be also understood that the operating movement of the anvil is relatively the same distance whether the anvil has been adjusted closer to or' farther away from the nail inserting mechanism, the adjustment being for the purpose of accommodating soles of different thicknesses or for nailing brads of divers lengths.
While I have illustrated and described certain specific means for carrying out my invention it, of course, will be obvious to others skilled in the art to which the same pertains that various changes and modifications may be made therein without materially departing from the spirit of my invention, and I desire it understood that all such refinements and modifications are included within the scope of my invention as set forth in the appended claims.
Having thus described my invention, what I claim as new and desire to secureby Letters Patent, is
