JAMES H. \VARWICK, OF KOKOMO, INDIANA.
ROTARY WRENCH.
SPECIFICATION forming part of Letters Patent No. 596,31 1, dated December 28, 1897.
Application filed April 3, 1897. Serial No. 630,565. (No model.)
To all whom it Wt/i/Y concern.-
Be it known that I, JAMES H. WARWICK, a citizen of the United States, residing at Kokomo, in the county of Howard and State of Indiana, have invented certain new and useful Improvements in Rotary Wrenches; and 1 do declare the following to be a full, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
My invention relates to improvements in rotary wrenches of that class adapted to be used in putting on and removing the nuts from tire-bolts.
The objects of my invention are to provide a rotary wrench of that class whereby nuts may be easily and quickly put on and taken off of tire-bolts when applied to the tire and felly of a vehicle-wheel, it being understood that the spokes prevent a full turn of an ordinary wrench, thereby rendering its use slow and laborious for that purpose.
A further object of my invention is to hold the bolt-head flush with the outer face of the tire and to provide a ready means for engaging and disengaging the wrench with the nut and wheel.
The invention consists in the construction and combination of parts shown in the accompanying drawings and described in the following specification.
In the drawings, Figure 1 is a side elevation. Fig. 2 is a top plan View. Fig. 3 is a vertical sectional view on the line 3 3 of Fig.
' vided with the slot Z.
2, and Fig. 4 is a cross-sectional view taken on. the line A 4 of Fig. 1.
The frame A is preferably formed of cast metal and is provided with journal-bearings h, h, h, and h, two parallel rails t', and a jaw j. The parallel rails t' are substantially triangular in cross-section, and the lower edges serve as a track upon which the slideblock 70 travels. The frame A is also pro- A knob B, by which the tool is held, is secured to the top of the frame A by means of the screw-bolt m. A journal 0, carrying a cog-wheel 'n, immovably keyed thereto near its inner end and having a crankE secured to itsv outer end, is supported in the bearings h and h, the frame A having an opening 0, into which one edge of the said cog-wheel 'n extends. The crank E is secured to said journal 0 by the set-screw r and is provided at its outer extremity with a knob F, by which it is adapted to be turned. A journal D,having a knob G upon its outer end, is supported by the bearings h and h and carries a cog-wheel n, which meshes with the cog-wheel n on the journal 0. The journal is formed with a groove 3, in which the tonguet within the axial opening in the cogwheel n is adapted to lie. The inner end of the journalD has the opening u and has secured thereto the head II by the set-screw r. Th'e'interior of the head H is square, as shown at 'v in Fig. A, for the purpose of engaging the nut I. A band g, having an arm f, surrounds the journal D and is held in place by the ring 6. The arm f extends upward through the slot Z in the frame A. A coil-spring J surrounds the journal D between the ring e and the bearing h and serves to hold said journal normally in the position shown in Fig. 1. The cog-wheel n is held against slipping out of engagement with the cog-wheel n by the bearing h 011 one side and the projecting lug w upon the other. It will be understood that the cog-wheel n is not secured upon the journal D except by the tongue 25, which enters the groove 8 and causes the journal to turn with the wheel, but does not prevent the journal from sliding backward and forward while the wheel remains stationary.
In Fig. 3 a sectional view of a tire K, a felly L, a tire-bolt M, and a nut I shows the manner of applying the wrench.
In operation the knob B is grasped in the left hand, with the thumb upon the arm f, the right grasping the knob F on the crank E. The journal D is then slid back by means of the arm f, the wrench is placed upon the wheel with the jawj against the head of the tirebolt M, and the journal D allowed to slide forward until the head H engages the nut I, which has previously been started upon the bolt. By this means the head H is enabled to instantly engage the nut I upon the tire-bolt M as soon as the wrench is placed in position upon the tire, as above described. The crank E is then turned, which rotates the journal C, the cog-wheel n, the cog-wheel n, and the journal D, thereby turning the nut, and as the nut moves up the coil-spring J causes the head H to follow, and the end of the bolt will enter the opening a in the end of said journal. When the nut is tight, the arm f is again drawn back by the thumb, which releases the head E from the nut and projecting bolt end. The purpose of the slide-block 7a is to form a support when the wrench is used upon a narrow tire, as illustrated in Fig. 3. \Vhen used upon a wide tire, the block 70 is slid back out of the way, and the edge of the tire bears directly against the lower face of the parallel rails 2'.
Having described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-- 1. A rotary wrench of the class described, comprising a frame A, having bearings h, 7t, h, and 71/, a slot l, an opening 0, parallel rails 2', and a jaw j, journals 0, and D, supported by said bearings, cog-wheels a, and a, mounted upon said journals, one of said journals having a crank E, and the other provided with a wrench-head H, a band g, having an arm f, whereby said journal may be slid back and provided with a coil-spring J, whereby the journal is pressed forward, all substantially as shown and described.
2. A rotary wrench of the class described, having a frame A, provided with journaL bearings 72,, h, h, and h, a slot Z, an opening 0, parallel rails '1', a knob B, and a jaw j, in combination with a means for instantly engaging a nut upon a tire-bolt, and a means for turning said nut, consisting of the sliding journal D, having the arm f, the groove 8, and the head II, the cog-wheels n, and a, the journal C, and the crank E, substantially as set forth.
3. In a rotary wrench of the class described, the combination of a main frame A, having the journal-bearings 7t, 7t, 7t, and h, the knob 13, the jaw j, the slot Z, the parallel rails i, carrying the slide-block 71;; the crank E, the journal 0, and the cog-wheel n, with a slidably-mountcd journal D, having a groove 8,
a head II, a band 9, having an arm f, a coil-,
spring J, and a cog-wheel n having a tongue 6, within its axial opening adapted to enter the groove .9, in the journal D, substantially as and for the purposes shown and described.
4. In combination in a rotary wrench of the class described, the frame A, having the opening 0, the slot Z, the knob B, the jaw j, the parallel rails t, and the journal-bearings h, h, h", and 7t; the journal 0, having the cog-wheel 12,, the crank E, having the knob F, the slide-block 70, the journal I), having the groove 5, and carrying the knob G, the coilspring J, the ring c, the band g, having the arm j, the cog-wheel 02, having the tongue 25, within its axial opening, and the head II, adapted to engage a bolt-nut, substantially as set forth.
In testimony whereof I affix my signature in presence of two witnesses.
JAMES H. WARWICK. Witnesses:
JOHN J. Lookwoon, GRANT RAY.
