Specification of Letters Patent.
Patented June 13,1916.
Original application filed January 2 5, 1915, Serial No. 4,088. Divided and this application filed February 26, 1916. Serial No. 80,563.
To all whom it may concern:
Be it known that we, WALTER S. MoKEn, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, and FRANK E. JOHNSON, a citizen of the United States, and a resident of Salt Lake City, in the county of Salt Lake and State of Utah, have made and invented certain new and useful Improvements in Crusher J aw-Plates, of which the following is a specification.
This invention relates to crusher jaw plates, and more particularly to those formed of interchangeable sections.
This application is a division of our copending application #,088, filed Jan. 25, 1915 An object of the present invention is to provide a sectional aw plate wherein the various sections may be reversed, end for end, as well as interchanged. Improved means are provided, for accomplishing the aforementioned ends, which hold the various sections together and in fixed position without the use of bolts or other analogous means extending through the jaw of the crushing machine. The construction of the holding means is such that the various sections may be easily and quickly interchanged or a single section either reversed or disrfaarded, and a new section substituted there- Other objects and advantages will appear as the description proceeds, wherein it is to be understood that changes in the precise embodiment of our invention can be made within the scope of what is claimed, without departing from the spirit thereof.
The preferred embodiment of our invention is disclosed in the accompanying drawing, wherein Figure 1 is a view in front elevation of our improved crusher jaw plat/e, portions thereof being broken away; Fig. 2 is a view in side elevation of the foregoing; Fig. 3 is a view in side elevation of a slightly modified form of crusher jaw plate; Figs. 4, 5 and 6 are views in side elevation disclosing further modifications of our improved jaw plate.
Referring specifically to the several views, the jaw plate is formed with the upper and lower wearing sections 10 and 11 identical in both size and shape and, therefore, interchangeable.
The jaw of a crushing machine (not shown) and with which the present type of jaw plate is used, is provided with overhanging or undercut ends, and, for this reason, the remote ends 12 of the upper and lower sections are sloped'or beveled in a forward direction, and, to render each section reversible, the adjacent ends 13 of the upper and lower sections are correspondingly beveled. The upper and lower sections, are thus rendered reversible as well as interchangeable; allowing all portions of each section to be equally worn away, and thereby obtaining a maximum amount of useful work from each section.
The forward bevel of the ends of the upper and lower sections requires the ends of the central and wedge-shaped section 14 to be beveled in a rearward direction. In order, therefore, to prevent this wedge-shaped section from falling forward and becoming detached from the upper and lower sections,
the sides of the upper and lower sections are provided with the recesses 15, which extend to the ends of the sections and enlarge at their remote extremities, as at 16.
The sides of the central section are provided with the recesses 17 extending entirely thereacross, and which are adapted to register and aline with the recesses of the adjacent ends of the upper and lower sections, thus defining continuous slots for the reception of holding keys. Straps-or holding keys 18 are positioned within these slots and are provided with the heads 19, which, fitting within the enlarged extremities of the slots, prevent the keys from working a loose.
The slots and keys may partake of many diverse forms, as illustrated in the modified types of crusher jaw plates, Figs. 3 to 6, inclusive. In the construction disclosed in Fig. 3, the recesses are in the form of key holes, whereas in 4, the recesses-in the upper and lower sections of the jaw plate are of uniform width throughout.
The jaw plate, illustrated in Fig. 5, has the upper and lower sections 20 and 21 provided with confronting U-shaped recesses 22, the ends of which aline with spaced recesses 23, extending entirely across the sides wardly beveled, and with the sides thereof of such shape that whenlthe several sections are assembled, U-shaped slots or recesses 26 are defined, spanning each juncture between the several sections. U-shaped straps 27 are fitted within the slots and rigidly secure the several sections together.
What we claim is 1. A crusher jaw plate comprising upper and lower sections with forwardly beveled ends; a central section with rearwardly beveled ends, and locking means spanning the j unctures between the several sections.
2. A crusher jaw plate section provided with forwardly beveled upper and lower ends, the sides of said section provided at their upper and lower ends with similarly and oppositely extending recesses, adapted to receive a key therein.
3. A central section for a jaw plate with the upper and lower ends thereof rearprovided with recesses extending to the upper and lower ends of said section.
4. A crusher jaw plate comprising a central, and upper and lower sections; the ends of the upper and lower-sections forwardly beveled, the ends of said central section rearwardly beveled, the sides of the upper and lower sections provided adjacent their ends with recesses, the sides of the central section provided with recesses adapted to aline with the recesses of the adjacent ends of the upper and lower sections, and straps positioned within said recesses, and spanning the junctures between the several sections.
Signed at Chicago, in the county of Cook and State of Illinois, this 23 day of February, 1916.
FRANK E. JOHNSON. Witnesses:
JAMES F. BEDDING, M. FIELD.
