UNE SS PAUL C. BALDUS, 0l?V MILWAUKEE', WISCONSIN.
Application filed April 23, 1920. Serial No. 376,124.
To all whom t may concern.'
Be it known that I, PAUL C. BALDUs, a citizen of the United States, and resident of Milwaukee, county of Milwaukee,i and State of lWisconsin, have invented new and useful Improvements in Wrenches, of which the following is a description, reference being had to the accompanying drawings, which are. a part of this specification.
The invention relates to a valve adjusting device and more particularly to a pair of tappet or valve rod adjusting tools, such as wrenches, operating inparallel planes so that two members may be adjusted with relation to each other and then locked by screwing up a lock nut with another tool.
The object of the invention is to provide a simple and economical wrench construction in which while the wrenches are disposed in spaced relation parallel to each other they are relatively movable with respect to each other to engage the nut portions of the members to be secured in adjusted relation. In many instances where devices of this character are used the nut portions of the members to be adjusted are of the same size and by the present construction the wrenches for engaging these portions may be duplicates of each other made from the same die. This feature is of importance where the devices have to be made to supply the demand for different sizes.
A further object of the invention is to provide an efficient construction for connecting the spaced wrenches together including an adjustable linkage of simple construction.
The invention further consists in the several features hereinafter set forth and more particularly defined by claims at the conclusion hereof.
In the drawings: Fig. 1 is a plan view of a device embodying the invention; Fig. 2 is a side elevation thereof; Fig. 3 is a section taken on the line 3-3 of Fig. 1; Fig. 4 is a detail plan view of a modified form of construction; Fig. 5 is a detail sectional view taken on the line 5-5 of Fig. 4. showing a modified form of connection; Fig. 6 is a section similar to Fig. 5 showing another form of connection.
In the drawings the numerals 7 and 8 designate the wrenches or holding members, the wrench 7 being designed to engage the head of a member 9, such as a bolt, and the wrench 8 engaging the fiat faces 10 of a member l1, said members 9 and 11 being adjustable with respect to each other and secured in adjusted position by means of a lock nut 12 on the bolt 9 which is tightened np by a third wrench A13. These wrenches be double ended, as shown in Fig. l, so
that two different sizes of wre-nches may be embodied in a single device and Vboth wrenches can be made from the same die where the nut portions of the members to be engaged are the same size.
, In Figs. 1 to 3 inclusive I have shown a linkage connection between the wrenches consisting of a pair of links 14 and 15 Vconnected together by a screw bolt 16, while in Fig. 4 I have shown Va single link 17 having a slotted end 18. In both instances one end of the linkage connection is secured in spaced parallel relation with the wrench 8 by means of a bolt 19 clamped to said wrench 8 by its head and a nut 20 and carrying an adjustable nut 21, a lock nut 22 and a wing nut 23. The other end of the linkage connection is secured to the wrench 7 by means of a bolt 24 passing therethrough and wing nut 25.
In Figs. 1 to 3 inclusive the free end of the link 14 is clamped between the nuts 21 and 23, the nut 21 having been previously adjusted to the proper distance on the bolt 19 and locked by the nut 22, and the free end Vof the link 15 is clamped between the wrench 7 and the nut 25.
In Fig. 4 the end 26 of the link 17 is clamped between the nuts 21 and 23 in a similar manner to that of the link 14 so as to be adjustably secured in spaced relation to the wrench 8 and the bolt 24 passes through the slotted end of said link to which it may be secured by the nut 25.
Where A an adjustable spacing of the wrenches is not desired the link 17 or the link 14 may be used to space the wrench 8 a fixed distance from the wrench 7 by providing a depending end 27 on the link, riveted or otherwise suitably Vsecured to the wrench 7, as shown in Fig. 5, or by providing a block 28 as shown in Fig. 6.
In the use of the device shown in Figs. 1 to 4 inclusive the spaced adjustment of the wrenches is first effected so as to bring the wrench 7 in the plane of the head of the bolt 9. Then through the loose connection of the double links 14 and 15 or the slotted link 17 the wrenches may be swung with respect to each other to bring them into positions to engage the nut portions of the members 9 and l1 and to allow the member 9 to be partially turned with respect to the member l1, if desired. The nuts 23 and 25 are then tightened up and with the Wrenches in proper position to hold the members 9 and 11 with one hand; the other Wrench 13 may be Vnsed to tighten up the nut l2 with the other hand.
I desire it to be understood that the invention is not limited to any specific form orV arrangement of parts except in so far as such limitations are specified in the claims. `Vihat I claim as new and desire to secure by Letters Patent is:
vl. The combination, With a pair of.
Wrenches provided with handles, of linkage connecting the handles of said Wrenches together permitting them to swing and move bodily relatively to each other, one end of said linkage having an adjustable spaced connection'vvith one'of the handles to dispose said Wrenches inparallel planes.
2. The combination, With a pair of Wrenches provided with handles, of linkage connecting the handles of said Wrenches together permitting them to swing and move bodily relativelyto each other, one end of said linkage having a spaced connection With one of the handles to dispose said Wrenches in parallel planes. Y
' 3. The combination, With a pair di Wrenches having integral handles, of a slotted link, means for adjustably clamping the slotted end of said link to one of the Wrenches, and means for connecting the other end of said link to the other Wrench in spaced parallel relation therewith.
4. A device of the class described come prising a holding member, and a pair of Wrenches carried thereby and capable of ready adjustment angularly With respect to eachother, said holding member having a pivotal connection With one of the Wrenches and a slidable connection with the other Wrench.
5. A device of the class described. comprising a holding member, and a pair of Wrenches carried thereby and capable of ad-V justment angularly and sideivise With respect to each other, said holding member having a pivotal connection With one of the Wrenches and a slidable connection With the other Wrench.
In testimony whereof, I affix my signature.
