CRANK-SHAFT-DRESSING MACHINE.

T 0 aZZ whom it may concern Be it known that I, Josmrr H. SUr'rEn, a citizen of the United States, residing at Wichita, in the county of Sedgwick and State of Kansas, have invented a new and useful Crankshaft-Dressing, Machine, of which the following is a specification.

My invention relates to the improvement in machines for dressing the hearings on the crank-shaft of an engine, and the object of my invention is to round up the bearings, without setting the crank-shaft in a lathe, thereby producing a true hearing.

I attain the objects of my invention by the mechanism illustrated in the accompanying drawings in which like characters represent like parts in the several figures.

Figure 1 is a side view of the dressing machine complete. Fig. 2 is an end view of the complete machine without the adjusting devices. Fig. 3 is avertical section with a part removed displaying the working parts of the dressing machine.

Fig. 4: is one of two gages. Fig. 5 is one of two cutting knives. Fig. 6 is the view of the upper end of the block, displaying the universal depth gage adjustment. Fig. 7 is a universal centering device in the lower end of the yoke.

In Fig. 2 P P dotted line, showing a division of the block.

In Fig. 3 the following characters indicate the following parts of the device :A is the yoke or frame of the device; B is the block that carries the cutter and universal depth gages. C C are the cutter knives; D D are the depth gages that regulate the cut of the cutting knives and are equipped with cogs that mesh with W; F F are the longitudinal ribs in the bottom of the yoke for supporting the shaft in the bottom of the yoke opposite to the cutting knives; G G are the universal centering arms for centering shaft in the dressing machine and are driven by screw Q and are journaled on It It; screw Q, is held in place by plate m, by screws m m; S is the adjusting worm drive for cog and worm wheels W which drive depth gages; 'I is the handle equipped with screw working in opening U of the yoke, for regulating the block B; Y is the lug on block which is a seat for handle T; O is collar on S to seat against lug Y; the wheels W W' are equipped with cogs on one side which operate the depth gages and screw on threads on the other side which are oper- Specification of Letters Patent.

ated by the adjusting screw S; I I are screws which serve as journal for wheels W W H H H" are screws for clamping block B together at dotted line P P on Fig. 2; L is the hinge in the yoke; U is the opening in the'yoke; N is the thumb, nut working on screw X which secures the lower part of the yoke to the upper; dotted lines K and K indicate the different size of the bearings which may be operated upon; d d indicate the position of depth gages; c 0 indicate the position of cutting knives when adjusted for smaller sized hearing.

In Fig. 4 are depth gages D D to mesh on cogs on wheels W N.

To operate this machine, unfasten nut N opening the yoke and placing it around bearing and fastening with thumb nut N wlth the bearing resting on the ribs F F, adjust the block down with the screw T until the cutting knives C C rest against the shaft; then adjust depth gages with the collar S, adjust self centering arms G G with screw Q after which revolve the machine around bearing.

I claim- 1. In the crank-shaft dressing device, a yoke comprising upper and lower members hinged together, self-centering arms mounted in the lower member, a screw for adjusting said arms, a block mounted in the upper member of said yoke, means for adjusting said block, removable cutting knives and adjustable cutting gages mounted in said block, and means for adjusting said gages, substantially as shown and described.

2. In a crank-shaft dressing device, a yoke comprising upper and lower members hinged together, two self centering arms mounted in the lower member, a screw threaded through the lower member and adapted to adjust said arms, the upper member having two parallel ridges extending from end to end thereof, a block mounted to slide on said ridges and having the lower end formed into an arc of a circle, a hollow handle threaded through the upper member and adapted to adjust said block, removable cutting knives and adjustable cutting gages set in said block and projecting beyond the arc, and an adjusting screw extending through said hollow handle and adapted to adjust said gages, substantially as shown and described.

3. In a crank-shaft dressing tool, a yok having a threaded opening in each end, the

inner surface of the parallel sides having double parallel ridges extending from end to end thereof, the lower end of the yoke being semi-circular, screw driven self centering arms mounted in said lower end, an adjustable block mounted to slide 011 said parallel ridges, cutting knives and adjustable cutter knife gages set in said block, a screw for adjusting said gages, and a screw for adjusting said block, substantially as shown and described.

4:. In a crank-shaft dressing tool, a yoke comprising upper and lower members hinged together and adapted to be opened and closed, self centering arms having parallel shaft-supporting ribs mounted in the lower member, a screw for adjusting said arms, a block adjustably mounted in the upper member, the lower end of the block being formed into an arc of a circle, removable cutter knives and adjustable cutter knife gages mounted in said block and adapted to be projected from said arc, a hollow screw threaded through the upper member for adjusting the block, and a screw drive extending through said hollow screw and adapted to adjust said gages, substantially as shown and described.
