BERNARD IVIOLSBERGER, OF FORT SAM HOUSTON, TEXAS.

RENEWABLE BROOM.

Application filed August 6, 1923.

To all whom it may concern:

Be it known that I, BERNARD MoLsBERGEn, a citizen of the United States, residing at Fort Sam Houston, in the county of BeXar and State of Texas, have invented new and useful Improvements in Renewable Brooms, of which the following is a specification.

This invention relates to brooms and has for its object the provision of a broom structure which may be called renewable inasmuch as it includes a head designed for permanent retention and use and so constructed as to clamp a bundle of broom straw to form the complete broom, the broom straw or other material being removable and replaceable by a new bundle when excessively worn.

An important object is the provision of a broom of this character which will be simple and inexpensive in manufacture, a great economizer and a general improvement in the art.

With the above and other objects and advantages in View the invention consists in the details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings in which:

Figure l is a front elevation of a broom constructed in accordance with my invention,

Figure 2 is a vertical section therethrough taken through the center,

Figure 3 is across section on the line 33 of Figure 1,

Figure 4: is a detail section showing the mounting of one of the clamps and Figure 5 is a perspective view of one clamping member.

Referring more particularly to the drawings I have shown my device as comprising a hollow head constructed of suitable material preferably metal and which might be a casting or stamping as preferred, and which may moreover be finished in any desired manner to have a pleasing appearance and to avoid rusting or corrosion. At its top this head is formed with a threaded socket 11 which receives the threaded lower end of a suitable handle 12. In conjunction with this head I make use of a bundle 13 of broom straw or other material of a like nature, which bundle is sewed at 1 1 in the customary manner with cord or the like to hold the fibers together, though it should be distinctly understood that this bundle or broom Serial No. 655,99?v

proper is not as elaborate in its formation as the conventional broom head.

For holding the broom head proper within the holder, I provide a pair of elongated clamping plates 15 provided with teeth 16 which will bite into the broom head or material for obtaining a firm grip thereon. It is to be noted that the ends of these clamping members are curved so as to conform substantially to the cross sectional configuration of the broom head or bundle. Screwed through the sides of the holder 10 are screws 17 provided at their outer ends with handles 18 and having their inner ends reduced as shown at 19 and threaded as indicated at 20. The outer sides of the clamping members 15 are formed with hollow bosses 21 having threaded holes 22 therein.

In assembling the clamping members, the screws 17 are turned so that the threaded ends thereof will be screwed through the holes 22 and will then be passed entirely therethrough with the threaded ends located within the hollow bosses and the reduced neck portions 19 passing through the holes 22. This is the equivalent of a swivel connection and will permit adjusting of the screws 17 in or out as the case may be without disconnecting them from the clamping members. The broom head proper 13 is clamped between the members 15 and is held firmly by screwing in the screws 17. The broom is of course used in the same manner as any other but has the great advantage that when the broom proper becomes worn out it may be replaced with a new one after loosening the screws 17 In this way it is quite obvious that the device will be very economical in use especially in such places where large numbers of brooms of ordinary construction are employed and discarded each week.

lVhile I have shown and described the preferred embodiment of the invention it is of course to be understood that I reserve the right to make such changes in the form, con struction and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention I claim:

1. A device of the character described comprising a hollow holder formed with a socket for engagement upon a handle, a broom head disposed within the holder, a

IOU

pair of elongated clamping plates within the holder at opposite sides of the broom head, and screws threaded through opposite sides of the holder and engaging said plates for holding the same in clan'lping relation to the broom head.

2. A broom structure comprising a holder of hollow formation provided with a socket carrying a handle, a sewed bundle of broom straw constituting a broom head proper disposed within the holder, a pair of elongated clamping plates located within the holder in engagement with opposite sides of the broom head, and screws threaded through the hold er and having a swivel connection with the clamping plates.

3. A device of the character described comprising a hollow holder formed with a socket for engagement upon a handle, a broom head disposed within the holder, a pair of elongated clamping plates within the holder at opposite sides of the broom head, and screws threaded through opposite sides of the holder and engaging said plates for holding the same in clamping relation to the broom head, said plates being formed throughout their lengths with ridges biting into the broom head for preventing shifting thereof and the ends of said plates being curved toward each other.

In testimony whereof I atfix my signature.

BERNARD MOLSBERGER.
