LUKE ANDERSON, OF LONDON, COUNTY OF SURREY, ENGLAND, ASSIGNOR OF ONE-HALF TO LEICESTER BRADNEY STEVENS, OF SAME PLACE.
REVERSIBLE BACK-STOP.
SPECIFICATION forming part of Letters Patent No. 396,188, dated January 15, 1889.
Application 'filed August 21, 1888. Serial No. 283,380. (No model.) Patented in England February 23 1887, No. 2,787, and in Belgium March 29, 1887, No. 76,900.
To all whom it nmy concern:
Be it known that I, LUKE ANDERSON, a subject of the Queen of Great Britam, residing at London, in the county of Surrey, England, have invented a certain new and useful Reversible Back-Stop for Revolving Shafts, (for which I have received Letters Patent in Great Britain, No. 2,787, dated February 23, 1887, and in the Kingdom of Belgium, No.
IO 76,900, dated March 29, 1887,) of which the following is a specification, reference being had to the accompanying drawings.
My invention consists of a novel kind of back-stop, which can be used in place of the I 5 ratchet-wheel and pawl hitherto used for this purpose and can be applied to any kind of revolving apparatus.
In the drawings, Figure 1 is a plan view of the back-stop, and Fig. 2 is also a plan view showing a modification of the back-stop,
A is a revolving shaft, which may be the main shaft of a turnstile or any other device which is ordinarly supplied with a ratch etand-pawl back-stop.
B is a toothed wheel secured upon shaft A.
O is a pinion, which gears into the said wheel B and is revolved by it.
E is a fixedbracket.
The pinion C is retained in gear with the wheel B by having its spindle journaled in the slot D of bracket E, as shown in Fig. 1, or it may be kept in gear by the arm D, one end of which encircles the shaft A.
The bracket E is provided with two holes,
F and F, one on each side of the pinion O, and G a stop pin or plug which may be slipped into either of the said holes. The slot D permits the pinion. O to vibrate, the amplitude of the vibration being limited by the length of the slot. The arm D also allows the pinion to vibrate, and the motion is limited by the stops H and H upon the bracket E, against which the arm strikes.
When the shaft A is revolved in the direction of the arrow in Fig. 1, and the pin G is in the hole F atihe left hand of the bracket, the pinion O is pushed to the righthand end of the slot 1) by the motion of wheel B, and the pinion continues to revolve as long as the revolution of shaft A is continned in the direction of the arrow. If the direction of the motion is reversed, the pinion O is pushed to the left-hand end of slot D and the pinion-teeth engage with the pin G, the pinion C and wheel 13 being thereby both prevented from revolving.
The device is changed to operate in the reverse direction by merely changing the pin G from hole' F to hole F.
The operation of the modification shown in Fig. 2 is precisely the same as that of the device shown in Fig. 1.
It is obvious that the back-stop may be arranged to work in one direction only by making the stop-phi G a fixture at either F or F.
What I claim is 1. The combination, with a rcvoluble shaft, of a toothed wheel secured on the shaft, a laterally-movable pinion gearing into the toothed wheel, and a stop adapted to engage with the said pinion and prevent the back motion of the shaft, substantially as set forth.
2. The combination, with a revoluble shaft, of a toothed wheel secured on the shaft, a laterally-movable pinion gearing into the toothed wheel, a fixed bracket provided with a hole on each side of the pinion, and a removable stop adapted for insertioninto either of the said holes for arresting the motion of thepinion, substantially as and for the purpose set forth.
The combination, with a revoluble shaft, of a toothed wheel secured 011 the shaft, a fixed bracket provided with a central slot and a hole upon each side of the slot, a laterally-movable pinion gearing into the said wheel and guided by the said slot, and astop adapted for insertion into either of the said holes for arresting the motion of the pinion, 0 substantially as and for the purpose set forth.
In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
LUKE ANDERSON.
