I'OWER-TRANSMITTING MECHANISM.
Application filed November 7, 1924. Serial No. 748,416.
This invention relates to improvements in power transmitting mechanism appertaining more particularly to the transmitting of power from rotary to reciprocating move merit. a a
An object is to provide a mechanism adapted to lengthen, to an unlimited extent, the reciprocating stroke from a crank or eccentric of given radius.
A further object is to provide a mechanism for transmitting power from a crankshaft or the like to cooperating members of opposed reciprocations and more especially to ad vantageously arrange the different parts of such mechanism and the distribution of the load.
A further object is to provide such a transmission wherein the parts are relatively few, the construction not complex and the cost of construction low, sol thus provide a mechani cal movement that is simple and compact and capable of producing a greater longitudinal movement from a cam or crank of given radius than is attainable by conventional practice.
To the accomplishment of these andrelated obj cots, my invention resides in the constructiomcombination and arrangement of parts as'shall be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the claims hereunto appended. i
In the drawings forming a part of this disclosure wherein like characters designate like parts throughout the several views,
Fig. 1 is a side elevation of a preferred embodiment of the invention applied to a compression cylinder;
Fig. 2 a plan thereof;
Fig. 3 an end elevation;
Fig. i a side elevation of a modified form; and
Fig. 5 isa partial plan thereof.
Referring particularly to these drawings wherein it will be seen I have mounted my device on a base 6 from which is reared the main or central standards 7, it will be apparent that the mechanism designated in generality by 8 is designed for use in connec tion with the air compressor 9. Thisis for purposes of illustration and should not be considered as defining the use of the device as its applications are obviously unlimited.
Transversely of the standard 7 and suitably jounnalled thereto at 10 is a rotatable shaft 11 that carries thefly-wheel 12, and continuing past said Wheel is supported in buslnngs 13 on the top of a standard it. A
gear or pulley wheel 15 is keyedto said shaft v 11 exterior of the standard 14 to which is connected power from any desired source.
A. pinion 16 keyed to the shaft 11 adjacentthe journal 10 meshes with a gear 17 also journalled in the main standard 7. This gear is fixed to a rotatable shaft 18 to which a wheel 19 is connected on each end. A diametrically arranged crank arm 20 is applied to the outer side of each wheel 19 and being rigidly connected thereto at one end as at 21 carries the connecting rods 22 and 23.
The connecting rod 22 operates on the connection 24 of a pair of lovers 25 and 26 arranged to form a toggle, the former of which has its end remote from said connection 24 pivoted, as at 27, to the standard 7 while the lever member 26 is pivotedat 28 to a horizontal reciprocating shaft 29. Bearings 30 on standards 31 support this reciprocating shaft 29. i
23, the latter of the connecting rods, connects at 32 to a like pair of toggle levers 33 and 34. As the'lever member 33 which is remote or diagonal from the pivotally anchored lever member 25, is joined pivotally to the outer sideof the standard3l adjacent the connection 28 of the lever26 to the shaft 29, and the remote end of the lever 34unites with a reciprocal memher35 which is the cylinder or chamber of the air compressor 9, it will be obvious that the turning of the disk 19 will rotate the crank 20 producing the actuation of the toggles composed of the pairs of levers 25 and 26 and 33 and 34-, through the medium of the connecting rods 22 and 23 attaining the opposed longitudinal movement of the reciprocating members 29 and 35. p
The compressor 19 includesthe reciprocating cylinder 35 on the sliding pillow block 36 and a piston 37, on the end of the reciprocating shaft 29, arranged therein. A complete stroke, starting with the crank 20 in vertical position so the toggle levers centres are separated by a maximum distance, at which time the cylinder is closest the mechanism and the piston driven right into the head, takes but one half a revolution of the wheel 19 in which the crankends of the connecting rods describe arcs of 180 and the crank 20 again becomes perpendicular with the connecting rods 22 and 23 replacing each other in original position, during which the toggles having assumed a parallelism when the cylinder head and piston are farthest apart,- and passing on to the termination of the stroke, the toggles are spread apart to their greatest extent though arranged oppositely to the commencement of the stroke and the piston has agam approached the cylinder head.
A modification, shown in Figs. 4; and 5, illustrates a further extension means that may be inserted and is merely demonstrative of the arrangement of these cooperating toggles 1n endlessseries and the nature of their connection and application.
The base, standards and driving mechanism are all identical with those shown in the three preceding views but a three point crank shaft 38 replaces the crank arm 20. The said three points A, B, and C; forming a right isosceles triangle in which A and C correspond with the diametrically opposite cranks in the crank shaft 20, shown in Figs. 1, 2 and 3 and B is at the apex of the right angle; each receive a connecting rod 39. That connected to G operates the reciprocating cylinder through the medium of the toggle levers, as in the former case, while the connecting rods 39 from the cranks A and B actuate pairs of toggle levers 40 and 41 respectively whose inter-connection is soarranged that their united stroke is obtained in terms of the reciprocation of a horizontally sliding shaft 42 on the end of which is the piston riding within the reciprocating cylinder.
This union or combination of the longitudinal strokesfrom the toggles 39, 4:0 and 41 by the connecting rods from the cranks A and B, is produced by. pivotally connecting the remote end of the toggle lever 40 near the cylinder to the main standard thus securng the reciprocation of the rod 43, provided with suitable bearings 44 on the standard 45, to which the farther toggle lever 40 is pivoted. One free end of the toggle 41 also pivotally connects with the reciprocating rod 43 and the other free end connects with the piston stem or rod 42.
Relatively located as the cranks A and B are, it is evident that when the former is at the topmost point in its path the toggle 38 is in retracted position and the crank B is horizontal with the crank centre so the toggle 4:1 is rectilinear or extended. It is just as obvious that when A has moved to a position horizontal with the crank centre and B is at the top, toggle 40 will be I arallel with the ground and the connection 0 the toggle levers 41 will be at its uppermost limit.
This transmission ma be further developed and the combine movement of the stroke delivering elements added to as wished or found desirable in practice thus allowing of the endless use and application of the invention.
From the foregoing description taken in connection with the accompanying drawings,
it will be manifest that a power transmitting mechanism is provided which will fulfill all the requirements of such a device, but as many changes could be made in the above description, and various embodiments of my invention constructed within the scope of the appended claims without departing from the spirit or scope thereof it is intended that all matters contained in the said accompanying specification and drawings shall be interpreted asillustrative and not in a limited sense.
