HANDLE-CLAMP FOR STREET OR STABLE BROOMS.

SPECIFICATION forming part of Letters Patent No. 508,522, dated November 14, 1893.

Application filed Janua y 28, 1893. Serial No. 460,066. model.) 1

New York city, in the county andState .of New York, have invented a new and Improved Handle-Olamp for Street or Stable Brooms, of which the following is a full, clear, and exactdescription.

My invention relates to an improvement in handle clamps especially adapted for use in connection with street and stable brooms, and it has for its object to provide a clamp by means of which a handle may be connected with the head of a broom in a manner which will admit of the handle being readily disconnected from the head and the position of the clamp reversed, thereby providing for the even and regular wear of the broom, since when the broom has commenced to show wear to a predetermined extent at one side, the handle can be placed at the opposite side of the head and the opposite side ofthe broom be brought directly into active wear, and the shifting of the handle may be effected from time to time as occasion may demand.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully described and pointed out in the claim.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar figures and letters of reference indicate corresponding parts in all the views. 7

Figure 1 is a plan view of the handle clamp, illustrating it as applied to the broom head. Fig. 2 is an end view of a stable or street broom, illustrating the device as applied to the head,-the device being inside elevation; and Fig. 3 is a vertical section taken essentially on the line 3-3 of Fig. 2.

In carrying out the invention the body of the clamp consists of two parallel side bars 10 and l1,which are connected near their rear by a cross bar 12. Each side bar at each end is carried vertically downward from the body, whereby jaws 14, are formed, standing at a right angle to the body. One jaw of each .side bar 10 and 11, is provided with a set screw 15, the said set screw being passed through apertures in the jaws the walls of which are threaded. The inner ends of the of the socket 18.

set screws are pointed, as shown in Figs. 1

- and-2; and near the head of each set screwa collar-16, is formed, which-limits the inward travel of the screws. The set screws are preferably placed in what may be termed the front jaws of the body of the clamp; and the 10 and 11 near their front ends, a split sleeve 20, is supported, the sleeve inclining downwardly and rearwardly, facing the front end The sleeve is parted at its upper portion and is provided at its ends with flanges 21, and through the flanges an adj usting screw 22, is passed in order that the flanges may be drawn together or forced apart as occasionrmay demand. The split sleeve 20, is located some distance above the body of the clamp, being supported bystandards 23, as shown best in Fig. 3, and while, the split sleeve faces the socket 18 the socket is considerably lower than the sleeve, as the former is located quite close to the body of the clamp, as illustrated in Fig. 2.

The handle A employed is made conical at its lower end, and the conical portion is passed through the sleeve 20 and into the socket l8; and after the sleeve has received the handle it is made ,to clamp it firmly by drawing the flanges 21 together through the medium of the adjusting screw 22.

In operation, the body of the clamp is placed over the head B of the broom, the jaws of the body extending downward at opposite sides of the head. The set screws, 15, are then turned until they enter the head and force the spurs 17 to enter the head also. Thus the body of the clamp is expeditiously and conveniently secured upon the broom head, and it isevident that it may also be readily removed and reversed, insuring the even wearing of the body of the broom at each of its sides.

The device is exceedingly simple, durable and economic in its construction, and the scraper may be brought into action whenever desired to loosen any object which it is desirable to have removed, and which can not be removed by the body of the broom.

In order that the broom handle may have horizontal back or body provided at its front and rear edges with dependinglugs or flanges 14 those at one edge being provided with clamping screws 16, an inclined socket 18 on the upper side of the back at the forward edge thereof an inclined split clamping sleeve 20 in rear of said socket and provided with a clamping screw 22, and the scraping prong or finger 19 projecting upwardly and forwardly from the socket 18, substantially as set forth.
