MAGAZINE FOR THE STORAGE OF SPARE PARTS.
Application filed mm c, 1920. Serial a... 92,772.
This invention relates to improvements in magazines for the storage of spare parts. Specifically, the invention consists in providing within a propeller a storage magazine for carrying spare shear pins. p.
In practically all outboard motors and in many launches it is customary to fasten the Y propeller to its-shaft by means of a transverse pinof relatively soft metal which will shear when the propeller strikes an obstacle. When such a pin has sheared, thereby saving the shaft and associated parts from damage, it is necessary to replace the sheared pin by another pin of likenature to re-establish a driving connection between the shaft and the propeller.' It is-the frequent experience of operators of craft so equipped that spare shear pins are not available when needed. This is particularlyatrue in the case of an 2 outboard motor which is portable and which is frequently used upon rented craft 1n which the operator has no place for storing accessories. It is the primary object of this invention to provide in the outboard motor itself a convenient place for storing spare shear pins so that the full supply of such pins will be at hand when needed.
J More particularly, it is my object to provide a magazine for spare shear pins in the a0 propeller itself so that when the propeller is removed for the purpose of withdrawing fragments of the broken shear erator will be confronted by a ofreplacement pins. It is a purpose 0 the invention to provide a storage magazine in such a location that even an operator unfamiliar with the particular motor so equipped, must necessarily discover the requisite shear pins if any attempt whatsoever is made to render the device operable.
In the drawings: Figure 1 is a view showingthe propeller in elevation looking into the storage magazine in its hub. v y Figure 2 is a detail view on a reduced scaleshowing-the lower portion of an outboard motor with a propeller embodyingv this invention applied thereto, the propeller hub being shown in section to illustrate the manner in which the shear pins are secured in place when the propeller 1s in use.
Figure 3 is a fragmental detail ofthe convoluted strip used in the construction of the specific form of magazine shown in Figure 1.
Like parts are identified by the same reference characters throughout the several views.
The design of the outboard motor to which the invention isapplied is broadly 2 material. The parts illustrated in Figure 2 include the usual vertical housing 5 for the drive shaft 6 which supports the submersible gear housing 7 through .which extends the propeller shaft 8. The propeller 10 has its hub portion 11 provided with a bore 12 which fits upon shaft 8 and is normally connected thereto by the shear pin 13. p
For streamline purposes the hub 11 of the propeller includes a skirt 15 which diverges from bore 12 and shaft 8 to meet the periph "cry 16' of the gear housing 7. This skirt provides ample. space. for accommodating spare shear pins. v
The invention consists in providing a magazine within the propeller hub 11 for spare pins of the type indicated at 13 in Fig ure 2. One of the simplest ways of forming the necessary pockets or recesses 18 into which such pins can be introduced consists in the use of a corrugated or convoluted strip of metal such as that shown in Figure 3. The convolutions are produced in the usual machines for that purpose and the strip of metal 19 is then bent to a eneral circular form and fitted within the '11: 15 of the propeller hub 11. The ends 20 and 21 of the metal strip overlie each other as is clearly indicated in Figure 1 and the various convolutions of the strip co-act with the interior surface of the skirt or wall 15 to provide recesses or pockets 18 in which the spare shear pins 13 are freely receivable.
Inasmuch as the skirt 15 abuts the rear surface 22 of gear housing 7 it will ob- While the use of a convoluted strip 19 is one of the simplest ways of making 'up this magazine, I do not desire to limit my invention to this specific disclosure.v
I claim:
1. The combination with a gear housing and a propeller normally assembled therewith and including a hub housing, of a magazine formed in one of said housings and opening in the direction of the other, whereby to be closed by said other housing when said housings are assembled and to be ex posed .when said housings are disassembled, said magazine being adapted to retain shear pins in a position where they are accessible upon the removal of said propeller and the consequent exposure ofsaid magazine.
2. The combination with ahousing and a propeller shaft projecting therefrom, of. a propeller mounted on said shaft and including a hub housing, a shear pin securing said propeller to said shaft with said housings in substantial abutment,'and a compartment in one of said housings openings toward the other and normally iendered inaccessible by the other, said compartment being adapted to receive a spare shear pin and ,to expose said spare shear pin when said housings are separated as upon the breakage of said first mentioned shear pin and the removal of the propeller.
which is adaptedto receive and retain a spare shear pin.
5. The combination with a gear housing and a propeller shaft projecting therefrom, of a propeller normally secured to said shaft and including a compartment opening axially of said propeller in the direction of said gear housing and capped by said gear housing in said normal propeller position, said compartment being provided with recesses for the storage of spare parts and being adapted to be exposed for the removal of said parts when said propeller is withdrawn from said normal position.
6. As a new article of manufacture, a propeller providing in combination an annular skirt and an annular member fitted therewithin, said member and said skirt being formed with complementary wall portions oo-acting to provide a series of recesses between said member and said skirt, each'such recess being adapted to receive a spare shea pin for said propeller.
7. In a device of the class described, a propeller shaft, a propeller on said shaft including a hub having therein a substantially axially opening chamber-forming a magazine, means on said shaft serving to close said chamber when the propeller isassembled therewith on the shaft, and means in said chamber adapted to hold in radially HUGO BIERSACH.
