UNIT ED STTES LOUIS GOLDSTEIN, 0F BROOKLYN, NEW YORK.
TRNOVER- MACHINE.
Application filed February 17, 1923.
To all whom it may concern.'
Be it known that I, Louis GoLnsrnrN, a citizen of the United States, and a resident ofthe city of New York, borough of Brooklyn, in the county of Kingsv and State of New York, have invented a new and lmproved rIgurnover Machine, of which the following is a full7 clear, and exact description.
This invention has relation to a turnover' machine, the same being in the nature of an improvement over a prior patent granted to meJune 14, 1921, and bearing United States Letters Patent No, 1,381,820.
The invention contemplates as its main object the provision of an apparatus for the facilitating of the 'turning over or inverting of tubular articles or structures such fabric belts or the like by means of which the inverting or turnover process may be rapidly accomplished without danger of iujuring the article and without requiring the services of a skilled operator.
As a further object the invention provides in an apparatus or machine of the character described means for adjusting the gripping elements whereby their relative spacing when in gripping position may be variedto render the device useful in connection with articles or structures of various thicknesses.
As a still further obj ect the invention contemplates a machine or apparatus of the character described which is extremely simplein its construction, inexpensive to manufacture and which is thoroughly reliable and highly efficient in its purpose.
With the above recited and other objects in view the invention resides in the novel construction set forth in the following specification7 particularly pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that the right is reserved to embodiments other than those actually illustrated herein to the full extent indicated by the general meaningl of the terms in which the claims are expressed;
vIn the drawings- Figure 1 is a plan view of a machine or apparatus constructed in accordance with the? invention. y
Figl 2 an4 enlarged detail sectional view taken'approximately on the line 2 2 of Fig. 3.
Fig.2 3 is a longitudinal sectional view Serial No. 619,723.
ber a complementary flared or frustoconical seat 14- is provided which is formed with a notch communicating therewith for a purpose to be hereafter set forth.. At the opposite end the inner member 11 protrudes beyond the end of the outer member 10 whereby the operator upon axial movement of the member 11 in one direction may7 draw the frusto-conical or flared portion 13 of the head 12 against the seat 14 Aof the outer member 10 and upon the movement in the opposite direction effect relative separation between the faces 13 and 14.
ln use and operation of the device the tubular structure A which may have either an Aopen or closed end B is drawn onto the spindle. There the end B is closed it is7 of course, understood that the headed end 12 of the inner member 11 is arranged at the closed end B. l/Vhere both ends of the structure A are open it is immaterial which end is arranged adjacent the headed end 12 of the member 11. Assuming that the structure A is provided with a closed end B as illustrated, the operator with the faces 13 and 14 separated7 draws the closed end B in between the two faces 13 and 1,4: allowing a portion of the material to lie in the notch 15; the members 10 and 11 are then moved axially with respect to each other to advance the faces 13 and 14 toward eachother whereby a portion of the end B of the structure A is gripped between said faces. The, turning over or inverting operation is then accom'- plished by grasping thel structure A adjacent the gripped end and pushing the same outward over said gripped end as illustrated in Fig. 3 of the drawings.
In order to provide means for .accompdishing the axial relative movement between the members 10 and 11 and. for locking the same to hold the gripping faces 13 and 14 in gripping` position with the structure A, a manipulating mechanism is provided which consits of a stationary supporting bracket 16 having an aperture 17 in which the inner end of the outer member of the spindle is positioned and retained by .means of set screws 18. 'The bracket 16 is preferably formed into a U-shaped clamp 19, one arm or side 2O of which is adapted to rest upon a table or bench C, the opposite arm or side 21 of which is designed to underlie in spaced relation the table or bench The arm 21 'is provided with a threaded aperture 22 through which a threaded shank extends the same being provided with a swiveled head 24 at its upper end and a manipulating handle 25 at its opposite end. This arrangement permits of al detachable rigid association of the bracket 16 and the spindle with a table, bench or other support whereby the spindle will be rigidly maintained in a spaced parallel position above the table. The end opposite from the headed end 12 of the member 11 which will be hereinafter termed the inner end and which projects beyond the inner end of the outer member 10 is threaded as at 26 and extends loosely into the axial bore 27 of one end of an operating rod 28. The opposite reduced end 29 of the bar 28 is mounted for sliding movement in a cup shaped bearing 30. The bearing 30 has its cylindrical portion 31 received in an apertured lug 32 provided on the bracket 16. The head portion 33 of the bearing 30 is of larger diameter than the 33 is centrally apertured vas at 35 to snugly receive the reduced end 29 of the operating rod 28 which extends therethrough and is pivoted as at 36 to an eccentric handle 37, lsaid handle 37 having bearing rollers 38 jonrnaled therein for engagement with the headed portion 33 of the bearing member 30. The medial portion of the operating rod 28 is exteriorly threaded as at 39 and has threadedly engaged thereon an adjustable abutment nut 40 and a binding nut 41. A coiled expansion spring 42 surrounds the operating rod 28 and is interposed between the adjustable abutment nut 40 and the inner side of the head 33. The opera-ting rod 28 forms a boss or extension from a slide block 45 which is suitably maintained against turning movement. The slide block is provided with apertured knuckles 46 and 47 the apertures ofl which `are in 'axial alignment with the bore 27 of the operating rod. The threaded end 26 of the member 11 extends through the knuckles 46 and 47 and a yrotary knurled adjusting nut 48 is interposed between the knuckles 46 and 47 vthat by turning the adjusting nut 48 an initial relative spacing between the gripping faces 13 and 14 may be obtained to adapt the machine or device to tubular structures A of various thicknesses. A binding nut 49 is also threaded o-nto the threaded end 26 of the member 11 to bear against the outer side of theknuckle 47 whereby when the adjusting nut 48 has been properly manipulated the bin-ding nut 49 will prevent accidental movement of the same.
in practice and where found desirable, a plurality of spindles of various diameters may be used and connected with a common bracket 16 in which instance the spindles are disposed in'parallel relation with the slide 'fi blocks 45 of each pair of spindles having a tongue and groove connection 50 and 51 which serves to permit of relative sliding movement of the blocks while at the same time preventing turning movement thereon. 1n this instance the spindles are provided with independently operable manipulating mechanisms. a Y
From the fore-going the operation is as follows: The operator after placing the tubular structure A over the end of the spindle with the eccentric handle 37 in an upright position to space the gripping faces 13 and 14 apart draws the outer end of the tubular structure about the end of the spindle to dispose a portion between the gripping faces. The operator then grasps and turns the eccentric handle 37 to a horizontal position thereby effecting relative axial movement between the inner member 11 and outer member 10 to advance the head 12 toward the outer end of the outer member 10 to cause the gripping faces 13 and 14 to tigl'itly grip the tubular structure A. Due to the fact that the bearingv rollers 38 have a past renter movement the members 10 and 11 will be retailed against the further moverment and the gripping faces locked in gripping position. The operator then proceeds to grasp the tubular structure A at a point inward from the end of the spindle and pulls downwardly thereon to effect the inverting or turning over lof the structure. Then the inner end of the structure has passed over the. outer end of the spindle and the gripped extremity of the structure, the handle 37 is swung upwardly to release the gripping faces. f
It will thus be seen that an improved form of turnover apparatus or machine is provided which greatly facilitates the turning over operation of any tubular flexible structure which it is desired to invert.
