SHERWOOD KINDS, OF CHICAGO, ILLINOIS, ASSIGNOR TO S. F. BOWSER & COMPANY, INC., OF FORT WAYNE, INDIANA, A CORPORATION OF INDIANA.
PUMP-DRIVE MECHANISM.
Application filed February 26, 1921. Serial No. 448,227.
To all whom it may concern:
Be it known that I, SHERWOOD HINDS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Pump-Drive Mechanisms, of which the following is a specification.
My invention relates to driving mecha nism for pumps, and the like, and has for one of its objects the provision of a simple and eiiicient dispensing pump mechanism adaptable for being driven either by power or by hand.
A further object is the provision of a simple and efficient hand drive mechanism which can be easily and-quickly attached or detached from a pump mechanism, or the like.
A still further object is the provision of a detachable hand drive mechanism adapted to operate a pump at slower speed on its working stroke than on its return stroke.
Other objects will appear hereinafter.
An embodiment of my invention is illustrated in the accompanying drawings, form ing a part of this specification, and in which- Fig. 1 is a longitudinal section taken through .a pump driving mechanism embodying my invention;
Fig. 2 is a section taken on line 22 of Fig. 1;
Fig. 3 is a view in perspective of a dog used in the construction;
Fig. 4 is a section taken on line 44 of Fig. 1;
Fig. 5 is a section taken on line. 55 of Fig. 1; and
Fig. 6 is a vertical section of power mechanism interchangeable with the hand power device in Fig. 1.
In ordering dispensing pumps for gasoline, lubricating oil, and the like, persons often get such dispensing apparatus with hand power driving mechanism and then after using the same for a while want to apply power to such dispensing apparatus. It is the purpose of this invention to so form the driving shaft of such dispensing apparatus so that it may be provided either with hand driving mechanism or power driving mechanism.
Referring more particularly to the draw ings, I have indicated the fragments of a pump housing 4 with an opening 5 therein, and on the housing 4 is provided a casing 6 having a flange with openings 7 which may be secured to the pump housing 4 in any desired manner. Axially of the casing 6 are bearings 8 and 9, and in the bearings 8 is journaled a shaft 10 having a cupshaped enlargement 11 at one end thereof. At the other end of said shaft 10 is a restricted portion 12 on which is secured a manually operable crank 13.
The operating shaft 14 ofa dispensing pumpis shown extending axially into casing 6. with a restricted portion 15 journaled, in a bore 16 in the center of shaft 10. A. plate 18' has an opening in. which the shaft 14 is disposed and it may also'provide a bearing for said. shaft. On the plate 18 is a casting 19 having studs 20 and 21 thereon. On the stud 20 is a gear. 22 meshing with a gear 23, and the latter is journaled on stud 21. Gear 23 meshes with an internal gear 24 which has one end journaled in bearings 9 and the other end provided with a hub 25 journaled on cup member 11. Gear 22 meshes with teeth 17 out in shaft 14, as clearly indicated in Fig. 5. The members 19 and 18 may be secured to a portion of housing 4 of the pump in any desirable manner, such as by screws 26.
The hub 25 of gear 24 has a cylindrical bore 27 concentric with shaft 14, and in said bore is mounted a friction ring 28. Said ring has a plurality of solid lugs 29 engaging bore 27 and one or more springpressed lugs 30 also engaging said bore. I have indicated two lugs 29 and one lug 30, but the number may be varied as desired. The lug 30 is mounted in a suitable opening in ring 28 and has a spring 31 pressing it outwardly. Ring 28 is held against a shoulder 32 of hub 25 'by a plate 33, and the latter secured to said hub by screws 34, or their equivalent. In the end of cup 11 is formed a diagonal'cut or slot 35 in which is slidably mounted a dog 36. Said dog has an arm 37 disposed in a recess 28 in said ring 28 and a toe portion 38 on said arm engaging a notch 39 in said ring. Notch 39 and recess 28 are sufficiently large to permit easy movement of parts 37 and 38 in allmovements of the dog 36.
Shaft 14 has a member rigidly associated therewith with a notch 40 in said member inside of the cup 11. In the. present instance the notch 40 is formed in a sleeve 41 'formed integral or attached in any other be slid into notch id of collar 4E1 when the cation, Serial No. 381,868.
-with the hand drive mechanism,
desirable manner. Opening into the bore of hub 25 is a notch 43 with one side cut away as at d3" in Fig. 2. r
The casing 6 is preferably larger than the parts housed therein with a space 44 around said parts for the distribution of oil. A part l5 of this space extends up around shaft 10 in part as so that oil may be carried to all of the movable parts in said cas ing. Anoil filling plug is indicated at the top of casing 6 in Fig. 1, and a drain plug is indicated near the bottom of said figure. The partsbeforementioned are for driving the dispensing pump by hand.
In Fig. 6 l have indicated a power driven apparatus having a casing 6 attached to housingd of the pump casing. The casing 6 is formed so as to fit in housing i the same as casing 6 so that the power apparatus may be used or hand apparatus,
as desired. Axially of casing 6 is indicated'the driving shaft is of the pumping mechanism in substantially the same relation as the shaft occupies in Fig. '1 with respect to casing 6.
The power driving mechanism indicated in Fig. 6 may be any form of power driving mechanism desired, and that indicated is substantially the same as in my co-pending application, Serial No. 381,868, filed May 17, 1920, for fluid pressure motors. Said Fig. 6of the present application is substantially'the same as Fig. 10 in the application above referred to, with the exception of the change in shaft '31 of said application to fit shaft 14- in the present application.
In the present application a shaft i9 has splines 50 thereon registering with splines l2 of shaft with the collar 41 connecting said shaft 1 1 with shaft 49. The shaft 49 is indicated as mounted in bearings 51 in casing 6 with gear teeth 2 formed thereon meshing with a rack bar 53 which may be driven as set forth in my co-pending applie device is fitted the crank 13 is turned in one direction and this rotates shaft 10 witlits cup 11, thereby mov ing dog 36 around'cc-llar &1 and in hub 25. The friction 28 dog by toe 38 and rm Tn operation, when the it) 37 causes dog 36 to crank is turned in a clockwise direction. This provides a direct connection between shafts 10 and 14, thereby 0 using pump shaft is to be driven at the speed the crank is rotated. Upon rotating the crank 13 in a counter-clockwise direction, dog 36 is drawn by friction ring 28 outwardly into engagement ith notch 43 which looks the hub 25 bein connected to the stroke at faster rate than crank 13.
iihen the power driven apparatus is connected to pum shaft 1%, said shaft'is operated in the manner set forth inimy above mentioned co-pending application.
By taking out the'securing means from openings '7 of the flange of casing 6 the hand power device may all he slipped out of opening 5, with the exception of members 18 to 26, inclusive. The power driven apparatus may then beplaced in position and locked therein with the same securing means as used to hold the hand power mechanism in place and be ready for operation at once. I therefore be seen that either of the diving devices may be replaced with the other if a very simple and easy manner.
