REENFORC ING ROD HOLDER Filed Jan. 29, 1932 2 Sheets-Sheet 2 Patented Jan. 19, 1933 PAE DOLPH LOZELLE, F DETROIT, MICHIGAN nnnnroncine non nonnnn Application filed January 29, 1932.

This invention relates to a reenforcing rod holder and has for its primary object to provide, in a manner as hereinafter set forth, a device of this character embodying a novel construction, combination and arrangement of parts through the medi'umof which the same may be expeditiously attached to areenforcing rod without the necessity of threading the ends of said rod and which may be easily detached from the rod after the cement has become sulficiently firm.

Other objects of the invention are to provide a reenforcing rod holder of the character set forth which will be simple in construction, strong, durable, efiicient and reliable in use and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of thefollowing specification, taken in connection with the accompanying drawings wherein like characters of reference designate correspondwherein Figure 1 is a view in vertical section through a portion of a concrete form which has been filled with concrete showing a rod held in position therein through the medium.

of holders constructed in accordance with the present invention, said rod and holders be ing shown in side elevation.

designates a conventional form which has been filled with concrete, as indicated at 2. The reference numeral 3 designates a reenforcing rod which, for the purpose of con necting holders in accordance with the present invention thereto, is provided with substantially right angularly turned end portions 4.

' Thereference numeral 5 designates a bar of circular cross section which terminates, at one end, in a reduced shank 6. Extending into the shank 6 from its free end is a bore 7, said bore, of course, extending longitudinally in the shank. Also, extending into the shank 6 from its free end is a spiral slot 8 6 the inner end of which is spaced from the shoulder 9 at the inner end of the shank. The shank 6 is still further provided, at a point between the shoulder 9 and the inner end of the spiral slot 8, with a circumferen tial groove 10. The spiral slot 8, of course, communicates with the bore 7 Mounted on the shank 6 is a sleeve 11 having one end enclosed, as at 12. A key 13 is anchored in the open end portion of the sleeve 11 and engages'in the groove 10 for securing the sleeve on the shank 6 in a manner to permit relative rotation therebetween but to prevent relative longitudinal movement between the sleeve and shank. The inner end of the sleeve 11 abuts the shoulder 9.

The sleeve 11 is provided with a longitudi nal slot 14 which extends into the end wall 12 of said sleeve, as at 15. The slot 14: communicates with the spiral slot 8 in the shank 6 and the portion 15 of said. slot 14 communicates with the bore 7.

In use, the opposed walls of the form 1 are provided with aligned openings 16 for the reception of the holders. The ends of the rod 3 are inserted through the portions 15 of the slots 14: into the bore 7 of the shanks 6, the angular portions l of said rods projecting laterally through the spiral slot 8 in the shank and through the longitudinal slot 14 in the sleeve 1. The bars 5 are then given substantially a quarter turn, and the shanks 6 are drawn over the end portions of the reenforcing rod by the engagement of the end portions 4 of said rod in the spiral slots 8.

In this position, the sleeves 11 substantially close the bores 7 and the spiral slots 8 to prevent the entrance thereinto of the concrete when said concrete is poured and other foreign matter. After concrete has been poured and has had time to become sulficiently firm, the holders may he expeditiously detached therefrom by rotating said holders substantially a quarter turn in the opposite direction and withdrawing said holders from the form through the openings 16.

It is believed that the many advantages of a holder constructed in accordance with the present invention will be readily understood, and although the preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

lVhat is claimed is l. A rod holder comprising a member having a bore therein and further having a substantially spiral slot communieatingwith the bore, said bore and slot for the reception of the rod, and a sleeve rotatably mounted on the member having a slot therein communieating with the bore and the first named slot and accommodating the rod.

2. A rod holder comprising a member having a longitudinal bore therein and further having a substantially spiral slot therein communicating with the bore, said bore and slot for the reception of the rod, the member still further having a circumferential groove therein, a sleeve rotatably mounted on the member, said sleeve having a slot therein comn'ninicating with the bore and with the first named slot and accommodating the rod,

and a pin anchored in the sleeve and engaged in the groove for rotatably retaining the sleeve on the member.

3. A rod holder comprising an elongated member having a bore extending longitudinally thereinto from/one end thereof, said member further having a substantially spiral groove extending thereinto from said one end thereof, said spiral groove communicating with the bore throughout its length, said bore and spiral slot for the reception of the rod, and a sleeve, having one end closed, rotatably mounted on the member said sleeve having a slot therein communicating with the bore and the spiral slot and accommodating the rod, the slot in the sleeve extending into the closed end of said sleeve.

4. A rod holder comprising an elongated member having a bore extending longitudinally thereinto from one end thereof, said member further having a substantially spiral groove extending thereinto from said one end thereof,said spiral groove communicating with the bore throughout its length, said bore and spiral slot for the reception of the rod and, a sleeve, having one end closed, r0- tatably mounted on the member, said sleeve having a slot therein communicating with the bore and the spiral slot and accommodating the red, the slot in the sleeve extending into the closed end of said sleeve, the member still further having a circumferential groove therein, and a key anchored in the sleeve and engaged in the groove for rotatably retaining the sleeve on the member.

5. A rod holder comprising a bar of circular cross section, a reduced shank projecting longitudinally from one end of the bar, said shank having a bore extending longitudinally thereinto from its free end and further having a substantially spiral slot extending thereinto from its free end, said slot communicating with the bore, and a sleeve rotatably mounted on the shank having a longitudinal slot therein communicating with the spiral slot in the shank and with the bore in said shank, the slots and the bore accommodating the rod for detachably connecting the holder thereto.

6. A rod holder comprising a bar of circular cross section, a reduced shank projecting longitudinally from one end of the bar, said shank having a bore extending longitudinally thereinto from its free end and further having a substantially spiral slot extending thereinto from its free end, said slot communicating with the bore, and a sleeve rotatably mounted on the shank having a longitudinal slot therein communicating with the spiral slot in the shank and with the bore in said shank, the slots and the bore accommodating the rod for detachably connecting the holder thereon. the sleeve being closed at its outer end, the slot in said sleeve extending into the closed end of said sleeve.
