ROLLER-CHAIN.
Specification of Letters Patent.
Patented Aug. 15, 1916.
Application filed July 9, 1914. Serial N 0. 849,888.
To all whom it may concern:
Be it known that I, BRAuAH JOSEPH DIP- LocK, a subject of the King of Great Britain, residing at 3 \Vyfold road, Munster Road. Fulham, in the county of Middlesex, England, have invented new and useful Improvements in Roller-Chains, of which the following is a specification.
This invention relates to improvements in the spring roller chains described in the United States specification No. 1096893, and its object is to enable the rollers to be brought nearer together and thus increase the number of rollers in a given length of chain. Such chains as shown in the drawings of that specification had two sets of rollers in different planes, the plane of each set passing diametrically through the rollers of the other set..
According to the present invention the spring boxes are placed side by side with the rollers of one set and the plane of these rollers no longer passes diametrically through the rollers of .the other set but is shifted to one side so that the projections of a pair of adjacent rollers'on a plane at right angles to the length of the chain form a cross the arms of which divide the stem unequally.
The invention is applicable to single chains but preferably double 'or triple chains are employed as hereinafter described.
The invention also embraces certain details of construction. 7
Figure 1 is a side elevation (partly in section) and. Fig. 2 is a plan of a triple chain constructed according to this invention, and Figs. 3 and tare similar views of a double chain. Figs. 5 and 6 are sections on the lines and 6-6, Figs. 1 and 3. Figs. 7 and 8 are sectional end elevations showing the chains interposed between two surfaces moving relatively to each other. Figs. 9 to 17 are detached views of the parts of the chains.
The chains are to a great extent built up of parts which are the same for all the chains. Figs. 11 to 13 show a block 1 cut from a bar rolled in the L section shown at Fig. 11. This block has two holes bored in it the hole 2 being a plain hole while 3 is tapped. In the hole 2 is riveted the spindle 4 on which a horizontal roller 5 is mounted while the spindle 6 of a vertical roller '7 screws into the hole 3 and is secured by a split pin 8. In the double chain the roller 7 is mounted directly on the spindle 6 as shown at Fig. 6 but in the middle chain of the triple chain the vertical rollers of the middle chain are mounted on ferrules 9on the spindle 6 the two ferrules being forced apart by a spring 10 as shown at Fig. 5. If the rollers 7 tend to move axially the springs 10 allow of this movement without putting undue strain on the parts and bring the rollers back to their central position when they are'relieved from pressure. The other rollers may also be provided with springs for a similar purpose. The spindles of the vertical rollers of the two outer chains of the triple chain are attached to the loops hereinafter described and not to blocks 1.
11 are four sided spring boxes or frames which are preferably trapezoidal as shown at Figs. 1 and 16 but they may be rectangular as shown at Fig. 3. Two opposite sides of these boxes fit in grooves 12 (Figs. 11 and 13) in the blocks 1 and have in them holes through which the spindles l of the horizontal rollers pass. '13 are springs hearing at one end against the other sides of the spring boxes and at the other end against sheet metal loops 14 and 15 which have in them holes 16 to receive the spindles 6 of the vertical rollers. The loops 14 (Figs. 9 and 10) and 15 (Figs. 14' and 15) are'exactly alike except that 14 is sufficiently wider to fit outside 15 as shown at Figs. 2, 4, 5 and (3. The object of the boxes 11 being of trapezoidal form is to diminish the difference in the compression of the two sides of the spring when the chain is passing around a curve by causing a difference in the opposite direction when the chain is straight.
It wifl be observed that in both chains the tops of the horizontal rollers are only slightly below the tops of the vertical rollers while their bottoms are considerably above the bottoms of the vertical rollers so that the projections of a vertical and a horizontal roller upon a plane at right angles to the length of the chain forms a crossthe arms of which divide the stem unequally. It is desirable that the horizontal rollers should be barrel shaped as shown. Fig. 7 shows the manner in which the triple chain is used to prevent friction be tween two surfaces moving relatively to each other. One surface 17 is in the form of a trough while the other 18 is a flat sur face having two flanges 19 projecting from it. The rollers 7, run between the bottom of the trough 17 and the surface 18 while the rollers 5 run between the sides of the trough 17 and the flanges l9; j
The arrangement shown at Fig. 8 is similar to that shown at Fig. 7 but in this case the surface 18 only has one flange.
l. The combination of a row of sprin g frames, a set of 'rollers lying in one plane, each roller being interposed between and pivoted to the ends of two adjacent spring frames, and a second set of rollers in a different plane, each of the latter rollers being pivoted to the side of one of the spring frames.
2. The combination of a row of spring frames of-trapezoidal form, a set of rollers lying in one plane each roller being interposed between and pivoted to the ends of two adjacent spring frames, and a second set of rollers in a different plane, each of the latter rollers being pivoted to the side of one of the spring frames.
3. The combination of a plurality of parallel rows of rollers, adjacent rollers-in each row being in difi'erent planes, means for permitting some of the rollers to move axially, and springs resisting this n'iovement.
means for permitting some'of the rollers to m'ove axially, and springs resistmg this movement.
5. The combination of a row of spring frames of trapezoidal form, and'rollers in-' tel-posed between and pivoted to the ends of two adjacent spring frames.
- (3. The combination of a plurality ofparallel rows of spring frames, tWo sets of rollers lying in parallel planes, each roller being interposed between and. pivoted to the ends of two adjacent spring frames,'and a third set of rollers in a plane at right angles to the first planes, each of the latter rollers being pivoted to the side of one of the spring frames. i
