JOHN W. MACKENZIE, OF SAN FRANCISCO, CALIFORNIA.

IMPROVEMENT IN FLAG-HOISTING APPARATUS.

Specification forming part of Letters Patent No.126,46l), dated May 7, 1872.

I, JonN W. MACKENZIE, of the city and county of San Francisco, State of California, have invented certain Improvements in Flag Apparatus, of which the following is a specication:

The object of my invention is to provide an enabling means of clearing iags when foul aloft, vand to avoid the necessity of hauling them down and going through the various ensuing details necessary to clear and reset them, and to avoid the danger of tearing and soiling them. Another object is to provide mea-ns for a neater and more uniform system of bendingand setting' flags without encroaching upon established forms and regulations. The invention consists, first, of an improved truck, so arranged and combined in structure as to act automatically and in union with other means employed and acted upon by the wind. The truck is a round metallic box, arranged with a circular opening between the edges of its upper and lower parts. Its inside contains a carriage upon wheels, movin g upon an inside circular road that is formed upon either side ofthe circular opening. Connected with the carriage and coming through the opening to the outside is a means for attaching the halyard-blocks or thimble that is used for hoisting the flag, which is acted upon by the wind, and revolved around and cleared or prevented from becoming wrapped around the stati'. The trucks are made of a combination of metals; brass, wrought and cast iron may be used in making them; second, upon the lower part of the sta-ft', and in connection with the truck I use the follower for the purpose of saving the time and labor of unbelaying and belaying again. The belayed parts can be revolved around to a line perpendicular to the head of the nag. In construction it is a iat metal ring, working in a metal collar, and having belaying-pins upon its outer edge. Parts 3, 4, 5, and 6 relate to improvements that are applied to the flag itself, and having a necessary and dependent connection in carrying ont the object and purpose of the invention; third, is the roping of the edges of the flag with horse-ha-ir twine, thereby making it less prehensile, and preventing it from being held Wrapped fast aloft around the stays or other ropes. The twine is laid up two-stranded, and made with long jaws; fourth, is a selvagestrap for ting-heads. It is a marled skein, formed with two eyes in its bights, and is put over one partof the eyelet and single part of the head-cloth, then the other part of the head cloth is placed over the eyelet and. selvage, then the other plate is placed on and riveted down, showing the selvage between the headcloth. The selvage is used to prevent the twisting ofthe liag upon its head, as is the case when a twisted rope is used; fifth, is an improved brass grummet-buckle. lts iiange plate is formed with a neck in which the tongue is hinged. Theeye of the halyards is passed through the gruxnmet and buckled with the tongue. This does away with knotting or toggling. The utility of this device is neatness and despatch in bending. The grummet-buckles may be lnade either round or oval; sixth, the improved fair leader is made of wire, and is formed with a loop in the center. A rightand-left worm is formed on each of its ends. The bight of the hoisting part of the halyards is turned into the center of the worm, thereby avoiding the necessity of iinding the end and reeving it through.

Disclaimer.

I do not claim as new the principle of inner wheels working upon an inner roadway, as that principle was patented by me November 12, 1861; neither'do I claim any of the parts embraced in this invention separate from the uses and purposes in which they are employed, as set forth herein.

O'Zcim.

I claim- The combination of the roadway b b, metallic box-truck and followerfj', constructed and operated substantially as herein set forth.
