MOTION TRANSMITTING DEVICE Filed Dec. 1, 1933 2 Sheets-Sheet 2 pwm Attorney Patented May 1, 1934 MOTION TRANSMITTING DEVICE- Thomas A. Hofiner, Anderson, Ind., assignor of one-half to Charles N. Satterfield Application December 1, 1933, Serial No. 700,574
1 Claim.
This invention relates to a motion transmitting device, the general object of the invention being to provide means for converting a rotary motion into a reciprocating motion.
This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.
In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:
Figure l is an elevation of the device.
Figure 2 is a top plan view of Figure 1.
Figure 3 is a detail view, with part of the casing removed and showing parts in section.
Figure 4 is a section on line 44 of Figure 1.
Figure 5 is a sectional view through the rotary member and showing the key.
In these drawings, the numeral 1 indicates a two-part casing, the two parts of which are suitably connected together by bolts or screws 2 and said casing is formed with a small casing 3 in which is located a worm 4 fastened to a drive shaft 5. A rotary member 6 is located in the casing 1 and has a spiral gear part 7 formed thereon which is engaged by the worm. The member 6 is formed with a longitudinally extending bore 8 through which passes a shaft 9 which is formed with a double spiral thread 10, the ends of which are connected together by the curved parts 11. A
The ends of the spiral shaft 9 are reduced and supported by the end pieces 15 which also are connected to the guide bar 16 which passes through an eye member 17 on the casing 1.
From the foregoing it will be seen that when the worm 4 is rotated, it will rotate the member 6 and the key 12 carried by said member 6 will cause the shaft 9 to reciprocate due to the engagement of the key with the double spiral 10 of the shaft. It will be seen that when the key reaches an end of one spiral, it will pass into a curved part 11 which will cause the key to pass into the other spiral and thus the shaft will be moved in an opposite direction and thus the shaft will be reciprocated by the rotary movement of the member 6. Any suitable member which is to have a reciprocatory motion imparted thereto can be connected with the frame which includes the shaft 9, end members 15 and the bar 16.
It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.
It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.
What is claimed is:-
A device of the class described comprising a shaft having a double spiral groove therein, end pieces connected to the ends of the shaft, a guide rod having its ends supported by the end pieces and paralleling the shaft, a casing having openings in its ends through which the shaft passes, an eye forming part on the casing through which the rod passes, a rotary member located in the casing and having a bore through which the shaft loosely passes, said rotary member having a radial hole therein, the inner end of which communicates with the bore and said inner end being enlarged, a headed key having its shank fitting in the hole with its head fitting in the enlarged part, said head having a concavity in its inner edge for engaging the grooved part of the shaft, an exterior part of the rotary member having a worm formed thereon, a worm gear located in the casing and meshing with the worm on the rotary member, and a drive shaft connected with the worm gear.
