PIPE-FLANGE WRENCH.
Specification of Letters Patent.
Patented Aug. 24, 1920.
Application filed Marchv 26, 1920. Serial No. 369,040.
. renches, of which the following is a specification, reference being had therein to the accompanying drawing. Y
This invention relates to wrenches and has special reference to a wrench designed for use in applying or removing pipe flanges or the like.
The principal object is to produce a device of this character convenient of application to various sized pipe flanges and one that is of simple construction and durable.
Other objects and advantages of the invention will appear in the further description thereof.
Referring to the accompanying drawings forming part of this application and in which like reference characters indicate like parts:
Figure 1 is a face elevation of one embodiment of my improved wrench.
Fig. 2 is a transverse section on the line 2-2, Fig. 1 showing the engagement of certain adjustable parts of the wrench.
Fig. 3 is a side elevation of Fig. 1, and
Fig. 4 is a central transverse sectional View through the end of a pipe and standard flange.
It is to be understood that these wrenches may be made different sizes in proportion to the class of work for which they are in tended as each wrench has a predetermined limited adjustment in both directions, as is obvious.
The main portion of the wrench comprises a ring gear or ratchet-wheel 1 having formed integral therewith a spider comprising the radially disposed members 2-2 and 3-3, the latter having dove-tailed grooves 4 formed longitudinally thereof, the upper faces and outer ends of which are open. Into these grooves are slidably mounted the pin carrying dove-tailed arms 5 each of which carries adjacent the outer end thereof and securely fixed thereto a flange engaging pin 6 and I prefer to screw thread the upper end of each pin as at 7 so that when desired for special purposes a nut not shown, may be used on said pins after being applied toa flange to hold the wrench in place while being used.
Each arm 5 is held from accidental dislodgement by a channel 8 being formed longitudinally the lower face thereof and into which channel a screw threaded pin 9 projects when inserted through a suitable hole from the under side of the member 5 after proper positioning of the arm. By
this construction it is evident that the arms may be slid in or out radially to suit difi'en ent spacing of holes in the flanges.
At the juncture of the members 2 and 3 which forms thehub of the ring gear, is mounted an axial bolt 10 upon which is pivotally carried the actuating handle 11. A double dog 12 is pivotally carried at 13 upon the handle and a leaf spring 14 is pivotally mounted at 15 upon each edge of the handle adjacent the pivotal support of the dog and the free end of each spring engages the adjacent inclined edge of the dog, there being a groove 16 within the edge of the dog provided for such engagement and to prevent the springs from becoming accidentally dislodged therefrom.
In Fig. 1 the leaf springs 14 are shown as both engaging the dog 12 which results in the latter being held from engagement with the ratchet-wheel by either end of the dog and in this position the handle 11 may be freely swung about on its pivotal point without engaging the ratchet-wheel, then when either one of the springs 14 are removed from engagement with the dog and lowered against its respective stop 17 as shown in Fig. 3, the unobstructed action of the opposite spring will immediately bring its respective side of the dog into engagement with the ratchet wheel which will prevent free action of the handle 11 in the direction of the thus engaged side of the dog as the latter will automatically enter the nearest notch of the ratchet-wheel.
The wheel engaging portions of the dog are so shaped that the handle maybe readily moved in a direction away from that portion of the dog engaging the wheel without being hindered by such engagement and thus the wrench may be quickly adjusted to forcibly turn the ratchet wheel in either direction.
The dog 12 is formed adjacent its pivotal support with a hub portion 18 which bears against the adjacent coinciding notched wall ing of the dog.
I have shown in Fig. 4 a common pipe flange 20 as applied to a piece of pipe section 21 and the holes to which my improved dog is applicable are indicated at 22'there being a plurality of such holes in all these For all small sized flanges in ordinary work it would not be considered essential to use nuts on the pins 6 after being applied to a flange, but for special occasions and large posed opposed slots upon the outer face of.
the wheel,'radially adjustable arms mounted flanges the use'of such may be advisable.
It is evident that various modifications in the construction here shown may be re sorted to without departing from the combination of-elements disclosed in the appended claims.
' What Ifclaim is:
"IL A wrench of the character described com risin a ratchet wheel radiall dis- P a a y in said 'slots pins rigidly'fixed adjacentthe outer endsof the arms for engagement with an object to be turned, means for preventing accidental dislodgment from the wheel of the arms, a handle pivotally mounted centrally'upon the opposite side of the wheel to that of the arms, a double headed dog pivotally mounted upon the handle, the heads 10f the dog being alternately cooperatively engageable with the wheel and means for resiliently holding the dog with either head engaged, as the case may be.
2'. A wrench :of the character described comprising a ratchet wheel, radially disposed o pposed slots upon the outer face of the wheel, arms mounted in said slots radially adjustable beyond the wheel, pins rigidly fiXed adjacent the outer ends of the arms for engagement with an Object to be turned, and a handle pivotally mounted centrally upon the opposite side of the wheel carrying means for intermittent engagement with the ratchet wheel for turning it in either direction as desired.
In testimony whereof I hereunto affix my I signature in the presence of two witnesses.
