PINION GUARD FOR CIRCULAR LOOMS. APPLIOATION'IILBD mm: 17, 1904.
VERNON BOYLE, OF PATERSON, NEW JERSEY.
PlNlON-GUARD FOP CIRCULAR LOQIVISH Specification of Letters Patent.
Patented Jan. 30, 1906.
Application filed June 17, 1904. Serial No. 212,925.
To aZZ whom it may concern:
Be it known that I, VERNON BOYLE, a citizen of the United States, and a resident of Paterson, in the county of Passaic and State of New Jersey, have invented. a new and useful Pinion-Guard for Circular Looms, of which the following is a specification.
My invention relates to a pinion-guard for circular looms, and is intended to apply more particularly to a circular loom of the type shown, described, and claimed in United States Letters Patent No. 795,228, granted to Albert de Laski July 18, 1905, with the object in view of roviding a guard which will effectually shied the pinion from threads, dust, and foreign matter and which may at the same time, without the necessity of handling tools, be thrown back out of the way of the pinion for gaining access to the pinion for any purposes desired.
In the accompanying drawings, Figure 1 represents the guard in side elevation in connection with such parts of the loom as are in immediate proximity thereto, said loom parts being shown partly in side elevation and partly in section. Fig. 2 is a top plan view of the parts, taken in the plane of the line A A of Fig. 1. Fig. 3 is a top plan view in detail of the guard partially opened. Fig. 4 is a top plan view in detail of the collar and arm for supporting and looking the parts of the guard, and Fig. 5 is an end elevation of the same.
The pinion-guard consists of two sections 1 and 2, the body of each forming substantially one-third of a hollow cylinder and each provided with stem portions extending upwardly and downwardly from the body portions, the upwardly-extending stem on the body 1 being denoted by 3 and the downwardly-extending stem on the same body portion 1 being denoted by 4, it being assumed that similar upwardly and downwardly extending stem portions are also formed on the section 2. From the upward stem portion a lateral arm 5 extends and is provided at its outer end with a ring 6, which surrounds a vertical support 7, fixed in a suitable supporting-frame, in the present instance in an upper bracket 8 and. lower bracket 9. From the downwardly-extending stem portion 4 of the section. 1 an arm 10 extends laterally and is provided at its outer end with a ring 11, which embraces the vertical support 7. In a similar manner the upwardly and downwardly extendingstem portions on the section 2 of the guard are pro vided with laterally-extending arms 12 and 13, respectively, and these in turn are provided at their outer ends with rings 14 and 15, which embrace the vertical support 7. The construction is such that when closed, as shown in Figs. 1 and 2, the body port ons 1 2 will form continuously about two-thirds of a cylinder for embracing and housing about two-thirds of the pinion 16, fixed on the shaft or spindle 17 and driven by a pinion 18,111 gear with a master-wheel 19.
The upper and lower stem portions on the sections 1 and 2 fit and partially embrace the shaft or spindle 17 above and below the pinion 16, which the guard is intended to protect. The sections 1 2 may at any time, however, be swung apart on the vertical support 7 as a hinge-pintle traveling in opposite directions and being finally swung back entirely out of the way of the pinion 16 and its shaft or pintle. The guard-sections 1 and 2 are supported during this swinging movement by a collar 20, fixed on the upright 7 conveniently by means of a set-screw 21. The collar 20 is provided with an inwardly-projecting arm 22, which is provided on its upper face with a notch 23 for the reception of the lower of the two arms 5 and 12, in the resent instance the arm 5 on the stem 3, am; with a step 24 for the reception of the upper of said arms, in the present instance the arm 12. When the sections 1 and 2 are swung into their closed position, (shown in Figs. 1 and 2,) the parts will be held by the notch 23 and step 24 in closed adjustment by the action of gravity on the parts 1 and 2. When it is desired to open them out to gain access to the pinion 16, a slight lift will free them from their retaining-notch and step 23 24 and leave them to be swung about the upright 7, while they are held against vertical displacement by the collar 20.
From the above structure it will be clear that while the guard effectually houses the pinion 16 against liability of interfering with the threads or with foreign matter it provides a simple and effective means for quickly throwing the guard out of the way when ac cess to the pinion is required and that the locking of the guard in its place around the pinion is effected by gravity and. that it may by unlocked without the use of tools.
What I claim is-- 1. The. combination with a shuttle-driving pinion of a circular loom and its upright IIO shaft, of an upright support spaced from the spindle and a pinion-guard mounted on the said upright support and comprising hollow sections adapted to swing toward and away from each other into and out of position in proximity to the said driving-pinion.
2. A pinion-guard comprising hollow sections provided with laterally-extending arms for hinging the sections to a support and means for locking the sections in closed adjustment under the influence of gravity.
3. A pinion-guard comprising hollow sections provided with laterally-extending arms for hinging them to a support and a notched arm for receiving the arms on the sections to hold the sections in closed adjustment 4. The combination with an upright support, an upright shaft spaced from the up right support and a pinion on the shaft, of a pinion-guard comprising hollow body portions for housing the pinion and laterally-extending arms provided with rings for embracing the upright support and a collar adjustably secured to the upright support for holding the guard-sections against a downwardlysliding movement of the upright support, the said collar being provided with a notched arm projecting therefrom for locking the guard-sections in closed adjustment under the influence of gravity. 7
In testimony that I claim the foregoing as my inventionl have signed my name, in presence of two witnesses, this 13th day of June,
VERNON ROYLE. l/Vitnesses:
ELIAS BROWN KING, HENRY SOHOONOVER.
