Abstract: 1514455 Cutting loop pile fabric MILLIKEN RESEARCH CORP 19 July 1977 [13 Aug 1976 11 Aug 1976] 30284/77 Heading D1S Apparatus for cutting a loop pile fabric 10 with a selvedge comprises a rotor 12 or 14 with a plurality of rows of cutters 50, Figs. 2 and 4, arranged in operation, to rotate against the pile face of the fabric and cut the pile loops, a selvedge protector 48 at at least one end of the rotor and comprising protecting elements 54 extending between the rows of cutters 50 for holding the margin of the fabric away from the cutters, means 46 for sensing an edge of the fabric, and a servo-mechanism responsive to the means 46 automatically to adjust the position of the protector 48 in the axial direction of the rotor. As shown in Fig. 1, the fabric 10 is fed over two cutting rotors 12, 14 by rolls 18, 20 driven by a motor 16, the rotors 12, 14 being driven by separate motors 34, 36. Each rotor 12, 14 is cleaned by a brush 38 driven by a motor 40. Selvedge protector fingers 54, Figs. 2 and 4, each having a toothed surface 56 to provide a lateral pull on the selvedge, are positioned between each row of cutting blades 50 and are slidably mounted in notches in a collar 58 at each end of each rotor. Projections 92 on the fingers 54 prevent the fabric falling between the fingers 54 and the blades 50. At each end of their respective rotor, the fingers 54 are connected to a circular ring 52 engaged with the collar 58 and driven with the rotor. The ring 52 rotates about a stub shaft 60 movable coaxially of a shaft 64 by a hydraulic actuator (66), Fig. 3 (not shown), to move the protector 48 inwardly and outwardly. The edge sensor 46 is mounted on a bracket 80 on a member 74 movable with the shaft 60. If the fabric has a pile-free margin adjacent the selvedge thereof, the sensor 46 senses the selvedge when the width of the margin is less than a predetermined amount and, when the width of the margin exceeds this amount, the sensor 46 senses the edge of the pile. The sensor 46, Fig. 6, comprises pivotal flag members 120, 122 for sensing the selvedge and the pile edge, respectively, and jointly controlling the pressure of a fluid controlling the servomechanism. The back of the margin of the fabric runs against a plate 124 and the members 122 pivots in dependence upon the extent to which a feeler 128 thereon rides up the edge of the pile and thus moves away from the plate 124.

Title: Improvements in or relating to gradient meters, clinometers and the like
IPC: G01C9/08
Filed: 1923-12-07
Abstract: 230,186. Lynden, (Robert Aernout), Baron van. Dec. 7, 1923. Addition to 210,913. Clinometers.-In a gradient indicator or clinometer for moving vehicles, as claimed in the parent Specification, a weighted wheel is driven through differential gearing from a spindle rotated at a speed proportional to that of the vehicle, one member of the differential gear being connected to the gravityactuated indicator so that a constraining force due to the inertia of the wheel is exerted on the indicator when the speed of the vehicle varies. In the form shown the horizontal spindle 1 rotated at a speed proportional to that of the vehicle carries a pinion 6 gearing with a pinion 7 secured to a spindle 8 which also carries the pinion 9 forming one of the planet pinions of a. differential gear. Freely mounted on the spindle 1 is a sleeve 17 the lower end of which carries the sun pinion 19 and a plain portion 18. The floating annulus 13 is provided' with two internally toothed portions 15, 1'6 separated by a plain portion 14. The annulus is centred by rollers 10 carried by the planet pinions. The toothed part 16 of the annulus drives a second set of planet pinions 24 which are carried by a floating member 22 and are geared to a pinion 25 on a sleeve 26 coaxial with the sleeve 17 on which it is supported by a ball bearing 27. The weighted wheel 31 is carried partly by the sleeve 26 and partly by a sleeve 32 supported by a ball bearing 33 on a sleeve 34 secured to the spindle 1. The gearing is such that the inner race 34 rotates faster, and the inner race 17 more slowly, than the wheel, so as to eliminate the effect of friction in the bearings. The member 22 is provided with external teeth gearing with a pinion 37 on a spindle 38 which also carries a pinion 39 gearing with a sector 41 on an arm 42 secured to the pivoted bar 43 supporting the pendulum 44, 45. An extension of the spindle 38 carries the indicating-drum 40. A speedometer drum and a mileage indicator, actuated by the spindle 1 may also be arranged in the casing. In a modification the axis of the pendulum is coaxial with the spindle 1 and the inner races of the bearings 27, 33 are so mounted that one is stationary and the other rotates with the spindle, the gearing in this case being such that the wheel rotates at half the speed of the spindle.

Title: Improvements in automatic change-speed gear
IPC: F16H61/02
Filed: 1936-11-12
Abstract: 466,652. Automatic change-speed gearing. METZLER, H. Nov. 12, 1936, No. 30867. [Class 80 (ii)] Change-speed gearing is operated automatically according to torque by the slipping in succession of cam lobe clutches. In a preferred form, these cam lobes 7, 12, 14, Fig. 1, are directed axially so as to engage coned rollers or cam followers 3 on a carrier 2 splined on a load shaft 1 and thrust towards the lobes by a control spring 4. A driving-shaft 23 through a clutch 22 and middle shaft 5 drives directly the cam 7 with the shortest lobes. The shaft 23 through a countershaft 18 and one-way clutches 20, 17 drives the cams 12 and 14 at different reduced speeds, the lobes 12 overhanging the lobes 7, and the lobes 14 overhanging still further. A high-speed direct drive to the followers 3 and carrier 2, is effected in the position shown from the central cam lobes 7, the outer lobes 12, 14 being carried round at the same speed idly, with overrunning at 20 and 17. As the load increases, the lobes 7 slip round clear of the followers 3, with a yielding of the spring 4, and the load is picked up on middle speed by the lobes 12 and the free-wheel 20. On further increase of load, the lobes 12 also slip round clear of the followers 3 and the drive is picked up on first speed by the longest lobes 14 and the free-wheel 17. A manual control may be superposed by moving the carrier 2 against the spring 4 positively, or by manipulating the clutch 22 and solid gears 30, 29 in substitution for the freewheel gears 21, 19. A modification is shown in Fig. 5, in which che cam lobes 60, 61, 62 increasing in length in succession are radial and coact with cylinder roller followers 3 on spring-pulled oscillating frames 63 pivoted upon a carrier 2 fast on a driving-shaft 1, There are free-wheels at 17 and 20.
Patent GB-308707-A (GB)
Abstract: 308,707. Gounouilhou, D. March 27, 1928, [Convention date]. Totalizators; registering receipts.-In a ticket-issuing machine particularly applicable for totalizators or other registering apparatus, two electromagnets are employed one for connecting the machine with the operating source of power and the other for controlling the setting-mechanism. The ticket strip is fed from a roll 72 by means of rollers 68, 69, 70 and passes between separately operated platens 52, 48 and the various type carriers to the severing blade 76. The date type carrier 14 and value type plate 13 print the invariable matter, and the horse number, race number, and kind of bet (place or win) are printed by type on carriers 4, 11, 12 respectively, set by hand. The horse number is selected by a hand-wheel on the shaft of which is a triangular conducting plate 22 for bridging a fixed ring 24 and a series of contacts one for each horse number. A spur wheel 2 fixed to the shaft serves to set the carrier 4 and bears a locking rim engageable by a spring-controlled bolt 17 operated by a pedal. The various settings having been effected the pedal is depressed and the bolt 17 thereupon locks the wheel 2 and is latched up by a pawl 19 rigid with a lever carrying the armature of an electromagnet 21. The outer end of the lever is provided with a bridge 20 to complete the circuit for an electromagnet 38 which thereupon attracts a lever 35, Fig. 4, to clutch the motor-driven shaft 30<1> to the main shaft 42<1> adapted to drive shafts 43<1>, 44<1>, 45<1> and also to actuate through a star wheel 63 the voucherstrip feeding and printing rolls 68, 69, 70. The resilient platens 48, 52 are moved to impress the ticket by means of eccentrics on the shafts 43', 44<1> and the strip is partly severed by a knife carried by the platen 48. On the shaft 45<1> is a drum 45<a> provided with contact strips engaged by brushes to control the registering and operating circuits as follows. The parts having been set and locked by the pedal, the distributor 81, or 82, Fig. 5, depending upon the setting of the win or place switch 80 closes the registering circuit through the grand counter 83 or 84, switch 56, 57 provided by drum 45<a>, the magnet 21 and the selected horse counter 85 or 86. The magnet thereupon releases the pedal and the bridge 20 closes another circuit through a contact ring 60 on the drum 45<a> and the magnet 38. The ticket-issuing mechanism is now set in motion with the result that the registering circuit is immediately broken at 56, 57 and the magnet 21 is de-energized thus allowing the bridge 20 to return. Meanwhile however the operating circuit has been held by the contact ring 60 and a brush 61 until at the end of the cycle the circuit is broken at the interruption of this ring.
