' 1 Claim.
I" ,It `is one` object of theinvention to provide H The shaft Il is rotated simultaneously with an `elevator whereby items maybe transported from a given level to a higher or lower level `through the medium oi an endless chain or belt,
and presented for removal von either side oi tive to a horizontal plane during the period of Itlis `also an object oi the invention to provide an elevator of the character indicated where-` in theiitem supporting devices are positively and accurately controlled to travel the `entire circuit smoothly and without jar.
Finally,` it is an object of the `invention to` provide an `elevator of the character indicated that will be economical to manufacture, simple tical application.
In the drawing: i i i Figure l i'sa front elevation oi an elevator embodying my invention, partly broken away.
Figure 2 is a sectional View on line 22 of `In the particular embodiment of the invention as herein disclosed, I show at I `a recess in awallupon the sides of which are mounted brackets supporting a central bearing mem ber 3. i
l In the top portion oi member 3 is journaled a shaft 4 having sprockets 55c mounted on itsopposite ends to rotate therewith.
, Directly below shaft 4 and `journaled in the side walls` of the recess in parallel relation `to said shaft, is another shaft t having sprockets 1-"Ia mounted on its opposite ends `to rotate.
therewith.
`Mounted upon the sprockets and 50i-la i are belt chains ii--8a, and upon these chains The chain belts 8-`8a`land parts mounted thereon are driven in the directionindicated by f 'arrows I4 by means of a chain and sprocke drive to shaft 6, indicated generally at I5.
At I6 is shown a sprocket xedly mounted on astub shaft `II which is in turn rotatably mounted in the side wall of recess I directly below shaft B and in parallel relation thereto.
shaft t, and driven at thesame speed and in the `same direction, by means of achain and sprocket drive .indicated'generally at Ill.`
Mounted inthe bearing member `3 immediately below shaft l is a shaft I9 having a sprocket 26 rotatably mounted thereon in the plane of `sprocket I6, and on the two sprockets It and `2il is mounted a chain belt 2i.
In effecting the assembly above `described the chain drive I6, 2li, 2l `is aA duplicate of the chain plane parallel therewith,` with the axes of rotation of the several shafts `also lying in` the same plane. The shafts Il `and I9, however,
` drive 5, "I, 8, and is disposed to operate in a are offset vertically `with relation to shafts 4 and 6.
Mounted on chain ZIand `directed inwardly y toward the chain '8, are spaced pins 22, the spacing of these pins `being `the same as the spacing ofthe bars II carrying platforms Ill. When. completely assembled each forked arm or lever I3 engages one of the pins' 22, and the spacing between the axes of the bar II and pin 22 is equal to the .spacing` of the axes ofthe shafts 4 and I9, and shafts 6 and I'I.
The result of the construction described is that the position of the item carrying deviceremains unchanged throughout its complete path of travel. For instance, in the structure disclosed the carrier 9 has a horizontal floor surface as it travelsupwardlyon the vertical porn tion ofthe chain, and it is held in thatposition through the engagement of the lever Iii with a pin 22. Since the movement of pin 22 corresponds exactly with that of the bar II as they travel over their respective sprockets it follows that the horizontal position remains unchanged as the carrier travels from` one side of the elevator` to-the other as through thepositions im, 9b, 9c, and of course,` through positions Sd, te, 91. i The forked engagement of the lever with the pin 22 allows for any slight variations in the two chain structures without interfering with their accurate cooperation as described.
In this embodiment of the invention the carrier elements are travelling in the direction indicated by therarrows Ill with loading and unloading platforms at v23 and 2li respectively, but it is obvious that these carriers may be operated in either direction, with the platforms disposed at.
any height and on either side of the structure, also that itenismay` be placed upon the carriers 9 and removed therefrom, either manually orby automatically operated item handling. devices.
have herein shown and described but one specificr example `of the invention, changes in form construction, and method of assembly and operation may be made4 within the scope of the appended claim.
I claim: f
-The combination with an endless chain elevator having item carrying devices pivot/ally mounted thereon,k of means for maintaining each device in predetermined relationship with the horizontal, said means comprising, an endless control chain structure substantially duplicating the elevator chain structure and operable in a plane paralleling the plane of rotationof the elevator chain structure, with its axis of rotation lying in the plane of the axis of rotation of the elevator chain structure but offset relative thereto, a pin mounted on the control chain, and a forked arm xedly mounted on the item carrier with its forked end engaging'said pin, the spacing of the pivotal mounting ofthe carrierand the pin on the controll chain being equal to the offset between the axes of rotation of the control and'elevator chains, and means for driving the two chain structures `at a uniform rate of .speed in the same direction comprising, a drive shaft operatively associated with the elevator chain struc-l ture and driving means connected thereto, a drive shaft operatively associated with the; control chain structure and disposed to parallel the last mentioned shaft, and cooperating drive means connecting the last two mentioned shafts adapted to drive the second shaft at the samespeed as the first shaft.
