ROLL-BACK HUB FOR LOCKS.
No. 923,755. Specification oi Letters Patent.
Patented June 1, 1909. Application led September 8, 1908. Serial N o. 451,979.
To all whom it may concern:
Beit known that I, AUGUST ARENs, a citi-` zen of the United States, residing at New Britain, county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Roll-Back Hubs for Locks, of which the following is a full, clear, and exact description.
My invention relates to improvements in locks and particularly to an improved rollback construction.
In locks, the means commonly employed for operating the latch or bolt mechanism is what is termed alrollback", the general style of which is well known. Through this roll-back passes a knob or key spindle which, When manually turned, causes the roll-back to turn therewith. Suitable connecting devices leading from the roll-back to the bolt or latch cause said bolt or latch to be moved when the roll-back turns. Since a roll-back is ordinarily mounted so as to oscillate only within the lock case, the result is, if for any reason the lock should be applied to a door carelessly and so as to be out of a plane at right angles to the plane of the operating` spindle, a cramping` or binding of the spindle occurs which interferes with the proper action of the lock.
The object of my invention is to provide a construction which will overcome this obj ec tion to the ordinary roll-back.
In the drawings, Figure 1 is a side elevation of a roll-back constructed to embody my invention. Fig. 2 is a longitudinal section through the axis of the roll-back hub. Fig. 3 is a perspective view of -a detail of construction detached. Fig. 4 is a perspective view of a modification of the detail shown in Fig. 3.
My improved roll-back comprises the main body 1 having the reduced bearing ends 2 2 and the roll-back arm or arms 3 3. Extending longitudinally through the body 1 and from end to end thereof is a passage to afford clearance for a spindle. The usual cross-sectional outline of a spindle is square and in the present case such is preferably the outline of the spindle passage in the body 1. At asuitable point (preferably about midway) Within this passage is located one or more spindle bearing plates 4 4 these plates may be of any suitable shape externally and each of them is provided with a passage approximately fitting the spindle designed to be used, yet affording a slight play. The size of the passage through each plate 4 is somewhat less than the size of the spindle clearance passage through the body 1; the result is, when a spindle is passed through this rollback, it has its main operative bearing within the washer 4, the larger passage through the hub permitting said spindle to be tilted very considerably (as indicated by the dotted lines in Fig. 2), without danger of cramping or binding the roll-back.
In Fig. 4 I have shown a spindle bearing plate 4, in which the outer edge is angular instead of round, as shown in Fig. 3. This serves to better anchor the member 4a in place.
What I claim is:
1. A roll-back for locks comprising a main body, having bearing ends and having a spindle clearance passage therethrough extending from one end to the other', a separate perforated spindle bearing plate rigidly mounted Within said body and arranged to embrace a spindle and arranged transversely of the spindle clearance passage, the inner edge of the said spindle bearing plate projecting into and reducing the diameter of the spindle clearance passage.
2. In a roll-baol for locks, a main body l ranged therein, said plate having a rectanguhaving a spindle clearance passage extending therethrough from one end to the other, a
separate spindle bearing plate embedded Within the material ol the main body and arranged transversely of the Clearance passage therethrough, and at a point intermediate the ends of the same, and a passage through said bearing plate adapted to receive a spind e,
3. In a roll-back for locks, a main body having a spindle clearance passage extending therethrough, a perforated spindle bearing plate arranged and embedded Within the inaterial of the said body at a point intermediate the length oisaid passage, and arranged to reduce the diameter of the passage at such intermediate point through the roll-back and to afford a bearing Wall for the spindle.
il. In a roll-back for looks, a main body having a spindle clearance passage extending therethrough, a spindle bearing plate ar lar passage and being embedded partially Within the material of the said body, a pertion of said spindle bearing plate reducing the size of the passage through the roll-back to allord a bearing wall for the spindle, said plate being located intermediate the ends el the roll-back.
5. In a roll-back for looks, a main body having a spindle clearance passage extending therethrough, perforated spindle bearing plates arranged side by side and embedded Within the material of said body at a peint n* intermediate the length of said passage, said plates reducing the diameter of said passage at suoli intermediate point te allord a bearing Wall for the spindle.
