VALVE-GRINDER.

Specification of Letters Patent` Patented` Dec. 27, 1921.

Application led November 29, 1920. Serial No. 427,173.

To all whom t may concern Be it known that I, ANTON EMANUEL CARLSON, Swedish subject, (having declared his intention of becoming a citizen ofthe United States,) residing at Merchantville, in the county of Camden, State of New Jersey, have invented a new and useful Valve-Grinder, of which the following is a specification.

My invention consists of a novel construction of a valve grinder, wherein I employ a casing inclosing the principal operative parts, said casing having one side thereof removable and being provided at its upper and lower ortions with bearings for the spindle employed, said spindle having at its upper portion a pinion in mesh with a rack carried by a yoke, said yoke being operated by suitable cam mechanism, whereby the continuous rotation of the outer handle will impart an oscillatory movement to the spindie and its adjuncts.

It further consists of a novel construction of mechanism for transforming the rotary motion of the actuating handle and cam into oscillatory motion, the lower end `of the oscillatory spindle being provided with a suitable valve engaging implement, whereby the valve is oscillated upon its seat, according to requirements.

t further consists of other novel features of construction and advantage, all as will be hereinafter fully set forth and pointed out in the claims.

For the purpose of illustrating my invention, I have shown in the accompanying drawing, oneb form thereof which is at present preferred by me, since the same will give in practice satisfactory and reliable results, although it is t0 be understood that the various instrumentalities of which my invention consists may be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.

Figure 1 represents a side elevation of my novel construction of valve grinder, the cover of the casing being removed.

Fig. 2 represents a section on line 2-2 Fig. l, certain of the parts being shown in elevation.

Similar numerals o reference indicate corresponding parts.

Referring to the drawings 1 designates my novel construction of valve rinder, the same comprising a casing or bo y member 2, in which the operative parts of my invention are contained, said casin at its upper portion carrying the hand e member 3, having the hand piece 4. The upper inner wall of the casing contains the seat 5, into which is stepped the end (j of the spindle 7, on the upper portion of which is pinned the sleeve 8 of the pinion 9, so that the latter and said spindle rotate or oscillate in unison, said spindle and. pinion being retained in their proper position by the lower collar 10 pinned to said spindle, said collar bearing on the lower wall 11 of the casing 2.

The pinion 9 is in mesh with the rack or segment 12, which is carried on the top of the yoke 13, the latter being composed of the top 14, which carries the rack 12, the parallel sides 15 and the bottom 16 which oscillates on the pin 17, the latter having a head 18, and its outer end being secured or pinned in the boss 19.

The inner parallel walls 20 of the yoke 13 contact with the periphery of the cam member 21, the latter being of the form of a disk eccentrically secured to the pin 22, which is mounted in the boss 23 and seated or pinned in the seat 24 of the handle 25.

The operation is as follows As the handle 25 is rotated, the pin 22 and the cam or eccentric member 21 will be continuously rotated and the contact of the periphery of said cam 21 with the walls 20 will impart an oscillatory movement to the yoke 13, whereby the rack 12 will oscillate from right to left, thereby imparting an oscillatory movement to the pinion 9, the spindle 7 and its adjuncts.

By the provision of the handle 4, the opcrater can readily exert a longitudinal thrust upon the spindle 7 so as to exert the desired pressure upon the valve during the act of grinding the same upon its seat.

By the provision of the seat 5 a stepped bearing is formed in the upper portion of the casing 2, so that the spindle is effectively guided at its upper end 6 and at its intermediate portion where it has its bearing in the lower portion of the casing 2.

The collar 10 retains the spindle and pinion 9 and their adjuncts in the proper position with relation to the rack 12 and the yoke 13 is at all times properly positioned during its oscillatory movement by reason of the head or fiange 18 on the pin 17.

Upon the removal o1 the plate or closure 26, all the parts are readily accessible, as will be understood from F ig. 1, for the purpose of inspection, replacement or repairs, and upon the removal of the transverse pin which secures the pin Q2 to the handle and the removal of the transverse pin which secures the pin 17 in its boss, all the parts are readily accessible in case it is desired to replace any of the same.

The blade or implement 27 at the bottom et the spindle 7 is provided with the projections 28, Which are adapted to engage the valve, and it ivill be apparent that the plate or implement 27 can be used in the position seen in Figs. l and 2, or, it desired, it can be reversed and the projection 28 caused to engage the valve or other member to beground or oscillated. The implement 27 is held in its desired position by means of the iiat spring 29 having a pin 30 thereon, which is adapted to engage the holes 3i or 32, according` to requirements.

lt will be apparent from the oregoinfr that I have devised a novel construction or valve grinder, Which Will be cheaply manufactured and Will be durable and effective under all conditions, and which is not liable to readily get out of order.

lt will now be apparent that I have devised a novel and useful construction of a .valve grinder, which embodies the features l claim as new and desire to secure by Letters latent, is

l. ln a valve grinder, a casing, a removable plate at one side thereo't, a spindle having its upper end stepped into the upper portion of said easing and its intermediate portion rotatably mounted in the lower portion of said easing, a pinion on the upper end of said spindle, a yolre pivotally supported at its lower end in the lower portion or said asing, a. cam member eceentrically mounted on a rotary pin journaled in said casing, a rack on the upper end ot said yoke engaging said pinion, and a handle connected to said pin for continuously rotating the latter, thereby imparting oscillatory motion to said spindle.

2. ln a valve grinder, a casing, a spindle having its upper end provided with a bearing in the upper portion of said casing and its intermediate portion rotatably mounted in the lovver port-ion ott said casing, a pinion on the upper end of said spindle, a yoke pivotally supported at its lower end in the lower portion of said casing, and provided with internal parallel Walls, a cam member Within said easing and having its periphery engaging said parallel walls, a rotary pin on Which said cam member is eceentrically mounted, said pin being journaled in said casing, a rack on the upper portion ot said yoke engaging said pinion, a collar on said spindle adapted to engage the lower portion ot' said casing, and thereby to retain said pinion in mesh with said rack, and a handle connected to said pin for continuously rotating the latter and said cam member, thereby imparting oscillatory motion to said spindle.
