Definitions
- This invention relates to a mechanism adapted to be used especially in grinding valves, though it is "understood that the mechanism can be used in a variety of other ways for many other purposes.
- the object of the invention is to provide a device of this character with many new and useful features of construction and operation which will be disclosed as the description progresses, the novel features of the invention being hereinafter pointed out particularly in the claims appended to the said description.
- Figure 1 is a side elevation of the machine.
- Fig. 2 shows in plan the upper portion of'the mechanism.
- Fig. 3 is an enlarged view of the upper part of the mechanism shown in Fig. 1 and looking in the same direction.
- Figs. 4 and 5 are, respectively, side and plane elevations of an element of the mechanism.
- Fig. 6 is an edge view of a pulley and the crank-shaft on which it is mounted, forming a part of the mechanism of the device; and
- Fig. 7 is a view similar to Fig. 2 of a modified form of construction.
- a carriage 1 which includes in its construction an upright sleeve 2 adapted to receive the lower end of a post 3. It will be noted that the carriage is mounted on rollers making it portable, and that the lower end of the post 3 is loosely received in the sleeve 2 enabling the post to be rotated to carry the mechanism supported thereon to different positions.
- the portability of the carriage and rotation of the post permits the operating part of the mechanism to be carried to practically any desired point.
- a horizontal bar 4 is located a distance below the upper end of the post 3, its end adjacent the post being formed with a fork 5 partially surrounding the post.
- a vertical member 6 is secured to the bar adjacent the post 3 and lies parallel thereto, its upper end carrying a headed element 7 adapted to be received in a slot in the upper end of the post, which is formed as a hollow tube, so that the horizontal bar '4 and any mechanism carried thereby are readily detachable.
- a brace8 is used to reinforce and strengthen the connection between bars 4 and 6.
- a hanger 9 1s secured, its upper end extending a distance above the bar and a rod 10 lies between and connects the upper end of the hanger with the upper end of the bar 6 heretofore noted.
- a brace 11 attached to bar 4 and hanger 9 serves to steady the hanger and hold it in-position.
- Adjacent the post 3 an open frame is formed consisting of a bar 12 in the same plane and lying parallel to bar 4 being spaced therefrom but connected at its ends by a cross member 13 and a U- shaped member 14 as shown.
- an electric motor 15 is supported on a bracket 16 connected to the post 3, said motor driving, through the belt 17,'apul1ey 18 secured to and carried by the crank shaft 19 which is supported in suitable hearings on the bars 4 and 12.
- Shaft 19 is provided with a crank 20.
- a bevel gear 21 is mounted on a shaft 22 journaled in the hanger 9 and has a link 23 se cured thereto to which one end of a rod 24 is secured, the other end thereof being at tached to the crank 20. It will be evident that on rotation of the pulley 18 a reciprocating movement will be imparted to the rod 24 and that link 23 will be given a back and forth rotary movement about the axis of shaft 22.
- Link 23 is provided with a series of openings at different distances from the axis of shaft 22, the end of the rod 24 being connected to the link at these openings by any suitable connection. It will be evident that on moving the end of rod 24 toward the shaft 22 gear 21 will begiven rotation through a greater are with each semi-revolution of the pulley 18, than if it is moved farther toward the end of the link 23. In this way the gear 21 may be given a back and forth rotary movement through various arcs of revolution or if the end of the rod 24 is carried inwardly far enough the gear 21 may be given a continuous rotation in one direction.
- the hanger 9 at its lower end is formed with a stirrup-like support 26 carrying a bevel pinion 27 on a shaft 28 which extends through the support.
- This pinion meshes with the gear 21 and is driven thereby while shaft 28 connects, by means of the universal joint 29 with a shaft 30 rectangular in cross section inserted in and secured to the tubular sleeve 31 of similar interior cross section which at its lower end slidably receives a rectangular bar 32 terminating at its lower end in any suitable socket-33 adapted to receive any suitable tool such as a valve grinder or the like.
- a hand hold 34 may be loosely mounted on the shaft 32 at a distance above the socket.
- Electric wires 35 forming a part of a circuit lead from the motor and contain a suitable switch 36 which will be located adjacent the position occupied by the operator in handling the mechanism. It will be evident that on operation of this switch the mechanism may be started in motion and that the reciprocatory movements of rod 24 will serve to rotate shaft 33 a number of revolutions in one direction followed by a similar number of revolutions in the opposite direction except when the end of rod 24 has been moved inwardly sufficient that the gear 22 is rotated continuously in one direction.
- the universal joint 29 permits the operator to swing the tool carried by the socket 33 to different positions while the slidable connection of the shaft 32 in the sleeve 31 permits the raising and lowering of the tool with respect to the work on which it is engaged.
- FIG. 7 A modification in structure is illustrated in Fig. 7, the pulley 18 and crank 20 being operated and supported the same as previously described but the crank having attached thereto one end of a short rod 37 which, at its other end, is pivotally connected to a horizontal rod 38 having a rack 39 which meshes with a gear 10 secured to and rotating the shaft 28.
- Rod 38 is suitably supported in ways 41 and it will be evident that rotation of the pulley 18 causes a reciprocation of this rod and the rotation of the gear 40 in one direction followed by a similar rotation in the opposite direction, the tool carried by the mechanism in this manner being operated substantially the same as in the modification illustrated in Figs. 1 and 3.
- a support a bar positioned horizontally and detachably connected to the support, a pulley mounted adjacent one end of the bar, a crank connected with the pulley, a gear supported adjacent the opposite end of the bar, connections between the crank and gear to give the gear back and forth rotary movements on rotation of the pulley, means to drive the pulley, and a tool holding means operatively associated with and driven by the gear, substantially as described.

VALVE-GRINDING MACHINE.
Specification of Letters Patent.
Patented Aug. 31, 1915.
Application filed January 29, 1915 Serial No. 5,129.
To all whom it may concern Be it knownthat I, WILLIAM A. POWELL, a citizen of the United States of America, residing at Bay City, in the county of Bay and State of Michigan, have invented certain new and useful Improvements in Valve- .Grinding Machines; and I do hereby declare the following to be a full, clear, and
exact description of the invention, such as will enable others skilled in the'art to which it appertains to make and use the same.
This invention relates to a mechanism adapted to be used especially in grinding valves, though it is "understood that the mechanism can be used in a variety of other ways for many other purposes.
The object of the invention is to provide a device of this character with many new and useful features of construction and operation which will be disclosed as the description progresses, the novel features of the invention being hereinafter pointed out particularly in the claims appended to the said description.
In the drawings: Figure 1 is a side elevation of the machine. Fig. 2 shows in plan the upper portion of'the mechanism. Fig. 3 is an enlarged view of the upper part of the mechanism shown in Fig. 1 and looking in the same direction. Figs. 4 and 5 are, respectively, side and plane elevations of an element of the mechanism. Fig. 6 is an edge view of a pulley and the crank-shaft on which it is mounted, forming a part of the mechanism of the device; and Fig. 7 is a view similar to Fig. 2 of a modified form of construction.
Like reference characters refer to like parts throughout the several views of the drawings.
In the embodiment illustrated in the drawings, a carriage 1 is provided which includes in its construction an upright sleeve 2 adapted to receive the lower end of a post 3. It will be noted that the carriage is mounted on rollers making it portable, and that the lower end of the post 3 is loosely received in the sleeve 2 enabling the post to be rotated to carry the mechanism supported thereon to different positions. The portability of the carriage and rotation of the post permits the operating part of the mechanism to be carried to practically any desired point.
A horizontal bar 4 is located a distance below the upper end of the post 3, its end adjacent the post being formed with a fork 5 partially surrounding the post. A vertical member 6 is secured to the bar adjacent the post 3 and lies parallel thereto, its upper end carrying a headed element 7 adapted to be received in a slot in the upper end of the post, which is formed as a hollow tube, so that the horizontal bar '4 and any mechanism carried thereby are readily detachable. A brace8 is used to reinforce and strengthen the connection between bars 4 and 6. At'the outer end of bar 4 a hanger 9 1s secured, its upper end extending a distance above the bar and a rod 10 lies between and connects the upper end of the hanger with the upper end of the bar 6 heretofore noted. A brace 11 attached to bar 4 and hanger 9 serves to steady the hanger and hold it in-position. Adjacent the post 3 an open frame is formed consisting of a bar 12 in the same plane and lying parallel to bar 4 being spaced therefrom but connected at its ends by a cross member 13 and a U- shaped member 14 as shown.
Above the sleeve 2 an electric motor 15 is supported on a bracket 16 connected to the post 3, said motor driving, through the belt 17,'apul1ey 18 secured to and carried by the crank shaft 19 which is supported in suitable hearings on the bars 4 and 12. Shaft 19 is provided with a crank 20. A bevel gear 21 is mounted on a shaft 22 journaled in the hanger 9 and has a link 23 se cured thereto to which one end of a rod 24 is secured, the other end thereof being at tached to the crank 20. It will be evident that on rotation of the pulley 18 a reciprocating movement will be imparted to the rod 24 and that link 23 will be given a back and forth rotary movement about the axis of shaft 22. Link 23 is provided with a series of openings at different distances from the axis of shaft 22, the end of the rod 24 being connected to the link at these openings by any suitable connection. It will be evident that on moving the end of rod 24 toward the shaft 22 gear 21 will begiven rotation through a greater are with each semi-revolution of the pulley 18, than if it is moved farther toward the end of the link 23. In this way the gear 21 may be given a back and forth rotary movement through various arcs of revolution or if the end of the rod 24 is carried inwardly far enough the gear 21 may be given a continuous rotation in one direction.
The hanger 9 at its lower end is formed with a stirrup-like support 26 carrying a bevel pinion 27 on a shaft 28 which extends through the support. This pinion meshes with the gear 21 and is driven thereby while shaft 28 connects, by means of the universal joint 29 with a shaft 30 rectangular in cross section inserted in and secured to the tubular sleeve 31 of similar interior cross section which at its lower end slidably receives a rectangular bar 32 terminating at its lower end in any suitable socket-33 adapted to receive any suitable tool such as a valve grinder or the like. A hand hold 34 may be loosely mounted on the shaft 32 at a distance above the socket.
A modification in structure is illustrated in Fig. 7, the pulley 18 and crank 20 being operated and supported the same as previously described but the crank having attached thereto one end of a short rod 37 which, at its other end, is pivotally connected to a horizontal rod 38 having a rack 39 which meshes with a gear 10 secured to and rotating the shaft 28. Rod 38 is suitably supported in ways 41 and it will be evident that rotation of the pulley 18 causes a reciprocation of this rod and the rotation of the gear 40 in one direction followed by a similar rotation in the opposite direction, the tool carried by the mechanism in this manner being operated substantially the same as in the modification illustrated in Figs. 1 and 3.
Various other modifications in construction may be resorted to without departing from the invention defined in the appended claims and the invention is to be considered as comprising all modifications falling properly within the scope of said claims.
I claim:
1. In combination, a support, a bar positioned horizontally and detachably connected to the support, a pulley mounted adjacent one end of the bar, a crank connected with the pulley, a gear supported adjacent the opposite end of the bar, connections between the crank and gear to give the gear back and forth rotary movements on rotation of the pulley, means to drive the pulley, and a tool holding means operatively associated with and driven by the gear, substantially as described.
