OVERHEAD CARRIER.

Fairfield, in the county of Jefferson and State 'of Iowa, have invented certain new and useful Improvements inIOverhead Carriers, of which the following is a specification.

' My invention. relates to improvements in over e ad carriers, such as may be used in garages and other similar places .and 1t consists of the construction and arrangement of the parts whereby the hoistin' tackle which is attached to the carrier an prefer dmally. Also,

be h reinafter described and ably manually shifted to any point within specified limits, either laterally orlongituin the details of the construc tionand arrangements of the parts; as w1ll defined in the claims.

,In the accompanying dgawings form ng a part of this specification, Figure 1 is a perspective of an. overhead carrier embodying therfeatures of my inventlon. Fig.2 is an enlarged vertical transverse tion 'of the arrow.

line 33 of Fig. 1. F1gs.4 and 5 are enthe ceiling of-a building w porting beams B located thereon. O reprelarged detail views which will be described later on.

Referringto the drawings A represents hich has supsents-tlmbers which are spaced apart and connected transversely to said beams, so as to be above the portion of the room in which the overhead'carrier is to bperate. To each of these timbers an overhead track D'is hung by means of a series of, hangers E which maybe of any preferred construction. On these tracks carriers F are mounted so as to run past the hangers E from one end to theother of the respective tracks.

A thirdtimber G disposed transversely to the timber-G and't'racks- D is suspended to the carriers-F asshown in the drawing by straps H connected at their'upper ends to clevises I attached to the carrier frames so as to support the timber G in its transverse'positionbelow' the tracks D. A third track J is suspended to the timber G by means of a series of hen ers K which may be of a construction similar to that of the hangers E or of any suitable construction to support the track J so as to run past the 1 carrier L, as will more definitely section "on line 22- of Fig. 1; looking in the direc- -i 3 is'the same on ports Qhaving their the sprocket'wheel on that in either direction,

TO THE LOUDEN MACHIIENERY.

hang ers K from one; end of the track to the other. i

A hoisting tackle (not shown) will be connected to the carrier L as indicated by the section of chain M so that articles to be handled may be raised and lowered and be supported in' elevated. position by the those skilled in the "artto which my invention pertains. It will also be readily understood that when the article is suspended to the carrier L it may be moved aterally by pushing the carrier L along the track J, and also longitudinally by pushing the carriers Falong the tracks D. 'To facilitate this latter movement is the principal object of my invention and the means employed to accomplish this follows.-

A rotatable shaft N ismounted on the timber G so asvto project beyond the upper edge of the timber. Sprocket wheels 0 are mounted on the projecting ends of the shaft and horizontally disposed leading chains P' to the respective ends of t e timbers G, and preferably supported thereon by braces B. One end of the shaft N is extended beyond carrying a hand chain T is extended end of the shaft.

To move the carriers mounted on this x all that is-necessary is forthe operator to pull the hand chain'in one direction or the other. the shaftN to rotate and the sprocket wheels 0 to travel along the chain P in the desired direction, thus carrying the timber G connected to the carriers E along the tracks-D. By this 'means the track J with carriers L being attached to the timber G. will be drawn longitudinally to any desired point within the limits of the tracks D.

An-enlarged detail view of the sprocket wheel is shownin Fig. 2. The. shaft N' is preferably made of tubing and the sprocket wheels are secured toit so they will rotate ,wi th it. The links of the chain P are made object are as end and a wheel 'F along the tracks D" be readily understood by I up erends attached This will cause ner, and inorder to prevent the chain from slipping over a guard.U is provided. This 4: which is an enlarged view of the part looking up from the under side, the chain being removed.

. Theguard U is preferably made in two parts joined together by a rivet V as shown in Fig. 5, which isa transverse section on line 55,0f Fig: 4%. Theunder sides of the ends of the members forming the guard which is marked U are curved and made rounding Wherethey are joined together, thus making smoothly rounded and slightly hollowed faces for the chain to slide under when the sprockets are being rotated and the chain is passing over them.

The guard being loosely mounted on the shaft its ends will be free to tilt upward or. downward as they may be drawn by the relative .tightness o'r slackness of the ends of the chain on opposite sides of the sprocket.

In this way the chains the ends U of the guard will be effectually prevented from slipping over the sprocket and at the samejtime the pressureof the ends of the guard on the opposite ends of the chain will be always uniform.

Fig. 3 is a transverse vertical section of the timber G and track J, on the line 3-3 of Fig. 1, and shows the sprocket wheel 0, chain wheel S and oneof the track hangers K in the background. As shown in the strengthen it drawings the timber G is fitted on its upper edge with a horizontally disposed laterally projecting member W- which served to laterally and prevent it from buckling in carrying a. heavy load. Material other than wood may be used for the members C and G if preferred, and where the I beams B are not used the member C may be connected to the ceiling A in any suitable manner.

In the drawings and description relating thereto, I have merely undertaken to typify my invention, and, therefore do not wish to be understood as intending to limit the same to the details shown and described. It will be readily apparent that while the beams O and G are preferred as mediums from which the tracks or ways may be suspended, yet

i they may be omitted, and the parallel tracks by said .e

or ways suspended tural timbers of the building and the transverse track directly from the parallel tracks.

or ways.

What I claim is- 1. In an overhead carrier, the combination of an upper track, a carriage movable over the u per track, a lower track supported ement at an angle to the upper track, a carrier on thelower track, a toothed wheel rotatably mounted adj acentthe lower track and adapted to move therewith, means P being passed underdirect from the strucingly formed co-acting feed-track fixedly mounted adjacent and parallel to the upper track. v

2. In an overhead carrier, the combination of a pair of parallel tracks, carriages mounted for movement thereover, suspension. means for the carriages, a track disposed at an angle to and below the parallel tracks and supported by said suspension means of thecarriag-es, a carrier on the lower track,- a rotatable shaft movable with and supported adjacent the lower track, means for operating the shaft, a toothed wheel carried by the shaft, and a correspondingly formed 00- wheel and mounted the parallel tracks. 3. In an overhead carrier, the combination of a pair of parallel tracks, a pair ofcar- 'riers mounted on and adapted to traverse said tracks, a supporting member connected near its ends to and supported by said carriers anddisposedat an angle to the tracks, a track arranged parallel to and suspended from said supporting member, a carrier mounted on the latter track, and a propelling means carried by the supporting-member. Y

4:. In an overhead carrier, a pair of overhead tracks paralleling each other, a pair of carriers mounted on and adapted to traverse said tracks, a supporting-member connected to and suspended from said carriers and disposed at an angle thereto, a track suspended from and paralleling the supporting-member, a carrier movable on said latter track,

and means for moving said carriers on the and the tracks connected thereto, a track 1 suspended from said transverse supporting member in parallel relation thereto, a carrier mounted on and adapted to traverse said latter track and means to manually propel the aforesaid pair of carriers and to cause/them to traverse the aforesaid trackways. I

6. In an overhead carrier, a pair of horizontally disposed supporting members attached to the ceiling of a building in parallel relation to each other, a trackway suspended in parallel relation to each of said members, a pair of carriers mounted on and adapted to traverse said tracks, a supporting mamber connected near itsends to said carriers acting feed-track meshing with the toothed 1 adjacent and parallel to mounted on and adapted 1 and arranged to stand in transverse relat ion to the aforesaid pair of supporting members and the tracks connected thereto, a

track suspended from said transverse sup-' chain whereby the rotating of the shaft will cause the sprockets to transverse the chains so thatthe pair of carriers will traverse the parallel tracks carrying with them the transverse supporting member and the track and carrier connected therewith, and means to manually rotate the shaft.

7. In an overhead carrier, a pair of horizontally disposed supporting members attached to the ceiling of a building in parallel relation to each other, in parallel relation to each of said members, a pair of carriers mounted on and adapted to traverse said; tracks, a supporting member connected near its ends to said carriers and arranged to stand in transverse relation to the. aforesaid pair of supporting members and the tracks connected thereto, a track suspended from said transverse supporting member in parallel relation thereto, a carrier mounted on and adapted to traverse said latter track, a pair of horizontally disposed chains supported at each end by the aforesaid parallel supporting members, a

rotatable shaft mounted on the transverse supporting member, a sprocket wheel on each end of the shaft and connected to said chain whereby the rotating of the shaft will a trackway suspended cause the sprockets to transverse the chains so that the pair of carriers will traverse the parallel tracks carrying with them the transverse supporting member and the track and carrier connected therewith, a chain wheel on one end of the shaft, and an endless chain hung on the'wheel, whereby .an operator by pulling the chain in one direction or the other will rotate the shaft and cause the pair of carriers to traverse the parallel tracks.

8. In a device of the character described, a pair of overhead tracks and carriers arranged in parallel relation to each other, a transverse member suspended near its ends by said carriers, a track and carrier supported by said member, a rotatable shaft mounted in parallel relation on said transverse member and its ends projecting beyond the ends of said member, sprocket wheels on said projecting ends, a pair of horizontally disposed chains laid in the path of the sprocket wheels and having their ends rigidly supported, whereby the rotation of the shaft will cause the sprockets to traverse the chains as and for the purpose set forth.

9. In a device of the character described, a rotatable shaft having sprocket wheels thereon, anchored chains placed iii the path of the sprockets, guards loosely mounted on the shaft so their central portions will straddle the sprockets and having concave convex ends to slide over the chain and prevent it from slipping off the sprockets.
