TBAVERSING JACK.

Specification of Letters Patent.

Patented Mar. 9, 1915.

Application filed June 25, 1914. Serial No. 847,192.

1 0 all whom it may concern Be it known that I, Gnoncn W. TROUT- MAN, a citizen of the United States, residing at Caldwell, in the county of Sumner and State of Kansas, have invented a new and useful Traversing Jack, of which the following is a specification.

Hy invention relates to a traversing jack which is particularly adapted to. assist in the accurate lining up of crank shafts, j ournals and shafting in general.

-One of the leading objects of my invention is to provide a simple, compact, light weight traversing jack to assist in the accurate lining up of shafting inthe bearing bones in which the bearings composed of Babbitt or other anti-friction metals are,

cast.

It is well known that in lining up .the crank shafts on engines and the journals and shafting on many types of machinery that the bearing boxes are located on or so close to the main frame or body of the machine in which they operate that it is very difhcult to get any suitable means to assist in getting the shafting accurately lined up in the boxes preparatory to casting the bearings and my traversing jack being very compact, readily adapts it to being used where there is but little space and'where an ordinary jack couldinot be used. The device is also adapted to many uses in general machine and repair work where it is necessary to move objects both vertically and horizontally.

Another object is to provide the device with the necessary mechanism to give it both a vertical and horizontal movement so as to adapt it to moving the object it is desired to move, either upward ordownward or laterally, whichever is desired;

A further object is to provide the device with a rectangular shaped base member having sides and ends forming a rectangular shaped recess open at the top.

' Another object is to provide the device with a traversing member adapted to move upon the upper faces of the base. member and sustain the weight of the load placed upon the device.

A further object is to provide the device with av plurality of vertically positioned guide and guide-way members which are adapted to accurately guide theiupper member and its mechanism in its vertical movement.

Another object is to provide the device with a rectangular-shaped upper member that is adapted to having a vertical movement imparted to it and that will move with the traversing member and that has a centrally located flattened V-shaped depression or its equivalent in its upper surface adapted to retain thereon a shaft or other object which it is desired to move.

A further object is to so design the devic that it will occupy but little space andso" arrangement of parts, as hereinafter more fully described, illustrated and claimed.

In the accompanying drawings,'Figure 1 is a combined side elevation and top'plan view of a traversing jack embodying the present invention: Fig. 2 is a vertical cross section through Fig.1 on the line A A, a portion ofthe cylindrical surfaces being projected; Fig. 3 is a side elevation of the upper member, parts of it being in section, and shows the upper member and the two vertical guide members all formed .in one piece and rigid together; Fig. 4: is a perspectiveviewof aportion of the base member and shows the ends of the base member detachable from its sides and base; Fig. 5 shows a pair of the traversing jackspositioned on a horizontal surface and apiece of shafting mounted on the depressions in the upper members; Fig. 6 is a side elevation of'the traversing member, parts of it being in section and shows the vertical guide way members and the member in whichthe screw works, all formed in 'onetogether. 7 4

The traversing jack contemplated in this invention and which is adapted to the various lines of work previously described comprises a rectangular-shaped base member, composed of the sides 1 or their equivalent,lthese sides are preferably planed and are formed rigid with the base 2, the upper piece'and rigid surfaces 3 of the sides 1 are planed and polished and adapted to permit the traversing member 20, whose lower surface 21 is planed so as to easily slide upon these surfaces; these have a sufficient width to sustain the weight placed .upon them by the traversing member 20.

The ends 4 of the base member are prefer.- ably rigid andformed with the base and sides of the base member, or they may be composed of a separate member as shown by 4 in. Fig. 4 and be rigidly secured to the sides 1 and the base 2 by means of properly disposed screws or their equivalent. The centrally located rectangular shaped recess 5 or its equivalent being formed by the sides 1, the base 2, and the ends 4, provides a protected recess for the horizontally positioned screw member 5 to work :in. This screw member 5 is externally screwthreaded and passes through the internally screw-threaded perforation 26 in the member 24; this member 24 or its equivalent is rigidly secured to the under side of the traversing member 20 by means of the upper reduced part 25 which is slightly larger than its perforation 25 in the traversing member 20; the part 25 is forced into the perforation 25 by pressure and rigidly secured to the traversing member 20, or the part 25 may be externally screw-threaded and the perforation 25 internally screwthreaded and 25 screwed into 25 and thereby rigidly secured to the traversing member 20, or the member 24 or its equivalent may be rigidly formed on the traversing member 20 as shown in Fig. 6 in which the traversing member 20, the member 24, the vertical guide-way members 10 and the screw guideway member 14 are preferably a'casting and all formed in onepiece and then accurately machined.

From the previous description it will be readily understood that when the screw member 5 is rotated, its threads acting in the threaded perforation 26 in the member 24, will actuate the traversing member 20 according to the direction in which the screw member 5 is rotatedfand thereby move the entire traversing mechanism and the shaft or load upon it in a lateral direction. The screw member 5, has an'enlarged part 6, whose internal surface 6 or its equivalent is turned so as to be parallel with the planed surfaces ofthe ends 4, these internal surfaces 6 at opposite ends of the screw member act as end thrust bearings for the screw member 5.

8 is a semicircular projection centrally located upon the upper surfaces of the ends 4 and forms a portion of the bearing perforation 8 in the ends 4 in which the screw 5 rotates; this semi-circular projection 8- Atom: ofthe ends of the screw member 5 is located the bearing member 8 with its ing perforation 8 This bearingmember has its part 8 centrally perforated at 8 and the perforation screw-threaded toreceive the screw member 5 which is screwed into the threaded perforation 8 until the bearing, member 8 is rigidly connected-to the screw member 5. This bearing member 8 forms a bearing for the screw member 5 to rotate on and when it is desired to take the device apart, the bearing member: 8 can-be unscrewed from the screw member 5 which permits the removal of the screw member from the base member and the member 24.

The traversing member 20or its equivalent as shown in Fig. 21s perforated at 13 to receive the two guide-way members 10, which are cylindricall'y perforated as shown by 11, the guide-way members 10 are preferably slightly larger than the perforations 13 andareforced into them and rigidly secured to the traversing member 20, the screw guide way member 14 is slightly larger than its perforation 19 and is forced into the perforation 19and rigidly secured? to the traversingmember 20 or the guidescrewed into the perforations 13 and 19 and is cylindrically perforated and the perforation screw-threaded as shown" by 15' and is adapted to having the externally screwthreaded screw member 16 work vertically.

This screwmember 16 has an en-- in it. larged portion 17 with a plurality of rpere forations similar to 18 which affordmeans.

by which; the screw membencan be rotated, its upper portion 17 works in a suitable perforation in the upper member 22,. by

means of this screw .member 16, the uppermember 22 and-its guide members 12, which move vertically in the perforations 11 in the guide-way members 10, can be vertically moved either upward or downward as is desired, the guide members 12 being slightly. larger than the perforations 12 v are forced into these perforations and therebyrigidly secured to theupper member 22 which is provided with the central V-shaped depress sion 23 which is adapted to. retain a shaft, journal or other object upon its upper surfaceand to move it with the upper member either horizontally or vertically or this-upper member may have its upper surface plane if it is desired, so as to adapt it to objects with a plane surface. I

In operation. one or two of the traversing jacks may be used, the base member being positioned upon some stable object such as the floor or upon some part of the machine, the journal, shaft. orother object to be moved is positioned upon theupper member and preferably in the V-shapeddepression23 in the upper surface of, the upper member 22, if it is desired to raise or lower the shaft or other object, the vertical screwmember 16 is rotated either upward or downward until the object is in the desired position; if it is desired to move the shaft or other object laterally, the screw member 5 in the base member is rotatedin the proper direction, which moves the traversing member 20 and the upper member22. From this description it will be readily seen that any shaft, journal or other object it is desired to move either horizontally or vertically or both, can be quickly and easily located in a given position.

While I have shown and described the preferred form of this invention, I desire to have it understood that many changes may be made in the form, construction and arrangement of the parts, without departing from the spirit of my invention.
