To all whom it may concern:

Be it known that I, GEORGE HENRY DOWNS, a citizen of the United States, and a resident of North Powder, Union county, State of Oregon, have invented a new and useful Improvement in Overhead Traveling Carriers, of which the following is a specification, reference being had to the accompanying drawings as constituting a part thereof.

This invention relates to traveling carrier systems comprising an elevated cable or rail, a ycarrier traveling thereon, and a weight suspended from the carrier.

Tocomprehend the purpose of my invention, I will briefly describe the utility of the same, with respect to an overhead cable, from which description its utility for other purposes, as for example, an elevated rail, will be self evident.

In the case of an overhead cable, it is desirable to use lateral ropes or stays, at intervals along the course of the cable, to prevent the lateral swinging of the latter; but such arrangement would necessitate the lifting of the carrier across said lateral stays, unless the carrier was specially constructed, as in my invention; furthermore, it is desirable that the carrier be so arranged as to prevent it getting oil' and becoming displaced on the cable While traveling along the same, which occurrence is a most annoying accident.

My invention, therefore, has for its primary object to obtain a carrier which is so constructed as to be able to pass over crossing `stay-cables, and is furthermore so constructed that the same cannot become displaced on the cable or other track over which it is traveling.

To this end my invention comprises the arrangement and combination of parts illustrated inthe drawings and hereinafter fully described and claimed.

In said drawings, Figure 1 is a perspective side elevation of my improved carrier, representing the same as running on a carriercable having lateral stays, and my carrier being seen in the act of crossing one of such lateral stays; Fig. 2 is a side elevation of my carrier with its near side-portion removed, and representing my carrier as trav eling on a carrier-cable and in the act of crossingone of its lateral stays; Fig. 3 is a central cross-section of my carrier, representing the same in a similar situation as shown in the preceding ligure; and Fig. 4

is a sectional detail on a larger scale, showing a modiiied construction of my carrier, more fully explained in the body of the speciication.

Referring now to the letters as designating the parts described: My carrier comprises two sides pieces a, b, by which the load is supported, said sides being starshaped when looked at in side elevation, that is to say, each has a rim portion assembling radially projecting spokes c. The interior opposite faces of the spokes c are respectively made with recesses (Z,constituting a sort of annular run-way, concentric with the axis of the carrier.

The central portions of the sides a, b are made with registering apertures through which to insert an axle-bolt c, secured in place by nuts f, fastened on its projecting ends and made with a central boss-portion g, on which is journaled a grooved-rim wheel L, the latter' being arranged intermediate of the sides, as shown in the cross section Fig. 3. Supplementary nuts f are also secured on the extremities of the axle-bolt e, and between the nuts f, f are secured the members of a yoke t, as shown in dotted outline in Fig. l, to which to fasten the cable (not shown). The boss is so arranged that the sides a, b may be jammed against the same by the nuts f without binding the wheel it; Suspended in the annular run-way o1' recesses d, of the sides a, I), is a hanger i, made with lateral shoulders j, convexed on their under surface, as more clearly seen in Fig. 2, so as to ride on corresponding shouldenportions c, being wall portions of said recesses (l of the spoke-like rims c. In order to reduce the friction imposed by the shoulders y' of the hanger c', upon the shoulders 71,- of

Vsaid spoke-like rims c, it is practical to provide one of the bearing surfaces with ballbearings.

In the construction illustrated by Fig. 3, the ball-bearings Z, Z are seated in the bearing faces of the hanger z'. Supposing now that m represents a length of the carriercable, and n one of the transverse or lateral stay-ropes, and supposing further that my traveling carrier is in the act of crossing 105 011e of such lateral stays, as shown in the drawings, it will be noted that the spokelike rims c of the sides a., b have straddled the stay-ropes a, and therefore, as the carrier continues to move along the cable m,


the sides a, b will be rotated by reason of the contact of theiriinportionv c with the stay-rope, thus causing the hanger z' to pass from one series of recesses el in the sides to contiguous recesses thereof, withpthe result that the hanger will maintain its pendent position. In otherjvords, the hangerl merely slides from one series of spoke-likerim portions of the sides to anotherwhile passingjournal-pm, a wheel mounted centrally thereon, sldes mounted on said Journal-pm lateral stays.

In the modified construction shown in.

4, the spokes c2 of thev sides a, ZX are made .with-run-Waysor recesses o, arrangedv similar to the recesses cl of the previous ex.-A

, ample, butprovided with flangesv p, andthe hanger q is madefwith corresponding recesses r, r, so as to be adapted toridein saidrecesses 0, on said fianges 21,' and the ball-bearings Vs, s are provided .in `the bear,- ing faces of the spoke-like rim portionsrcg, instead of in the ,bearing I.faces ofthe hanger g, as in the previous example. The object of theilanges p and the correSPQILding-recesses r, rf is to obtainan interlocking,con-v tact between the parts, holding the same against separation by reason o f any lateral wrenching strain. Obviously, either of the constructions described prevents thezwheel t fromleaving the lcarriercable by reason of any accident The load is suspended vfrom the hook u Vof the hangerc'.

I Claim:

l. An overhead carrier consisting of1 a j ournal-lpin, a wheel mounted centrally thereon, sidesH mounted if on said j ournal-pin exterior ofthewheel, the rims of said sides extending beyond the peripheryof the wheel and constituting rims` therefor, and ,being divided into aplurality ofspoke-lile rim-y` projections,lspaced apart, so as to be adapt ed to straddle a cross wire, said spoke-like rim-projections being provided on opposed faces with a run-way, anda hangeradapted` toA slidein said run-way of the sides.

2. Anv overhead carrier consisting of` a journal-pin, a wheel mounted` centrally thereon, sideslmountedy onsaid journal-pin exterior .of the wheel, the rims ofsaid sides extending beyond the periphery of the *wheel and Iconstituting, rims therefor, and being divided into la pluralityv ofspolelike rimprojections, spaced apart, so as to be adapted to straddle a cross wire, said spoke-like terior opposed faces withrecesses constitut-- inga run-way, a hanger made with lateral flanges adapte-d to slide in said run-way of the sides, and ball-bearings interposed between the bearing faces of said lateral flanges of the hanger and the bearing faces of said run-way in the sides.

3. An overhead carrier consisting of a exterior ofthe wheel, the rims ofsaid sides extending beyond the periphery of the wheel and. constitutingrims therefor, and being divided into a plurality of spoke-like rimprojections, spacedapart, so as to be adaptedto straddle across wire, said spoke-like rim-projections being providedgon their interior opposedfaces with recessesconstituting a run-way, a hanger made with lateral flanges `adapted to slide in said run-way of the. sides, and means arranged to prevent the spreading of the sides apart by any undue lateral strain on they hanger, and ball-bearings interposed ,between the, bearing faces of said lateral flanges `'ef the hanger andthe bearing ,faces of said run-way in the sides.

4. An overheadl carrier consistingy of a.V

journal-pin, a wheel mounted centrally thereon, sides mountedlon saidgjournal-,pin exterior ofthe wheel, the. rims of said sides extendingl beyond the periphery of the wheel and i constituting rims therefor, andbeing GEORGE HENRY DOWNS.
